STUDY OBJECTIVES
The Commission of the Port of Seattle (the Port) requested that the staff of SeattleTacoma International 
Airport (the Airport) prepare a comprehensive review of commercial ground transportation (GT) operations 
at the Airport. To assist in preparing this review, the Port retained LeighFisher to research commercial 
ground transportation operations at peer airports and to document the relevant best practices. This review 
describes how other airports manage and operate the ground transportation system at their airport. This 
review also addresses how other airports are accommodating the rapid change in the ground transportation 
industry resulting from the introduction of transportation network (TNC) services (e.g., Lyft, Sidecar, and 
Uber) and peertopeer rental car services (e.g., Flightcar and RelayRides). 
The information presented in this report is intended to assist Airport staff develop and evaluate options to 
manage and operate groun d transportation considering the Port's key objectives for ground transportation 
operations and services at the Airport including: 
Provide the travelling public with superior service and a menu of transportation options 
Assure the 24 hours/7 daysa week availability of adequate ground transportation capacity to meet 
expected passenger demands 
Provide service in a manner that allows it to be efficiently and effectively managed by Port staff 
Establish business arrangements with the providers of ground transportation services that, at a 
minimum, allow the Port to recover its costs and potentially increase revenue 
Promote opportunities for small businesses 
Expand economic opportunity for the region 
Support regional environmental and sustainability goals 
In addition to these key objectives of the Port, Airport staff wish to implement programs that: 
Are consistent with best industry practices including those used at peer airports 
Conform to the legal and operational constraints within which the Port must operate 
Consider a 5 to 10 year time horizon (which is prior to any major renovations to SeaTac's roadway 
system associated with the Sustainable Airport Master Plan (SAMP), currently in development) 
The initial sections of this report define the terminology used in this report and list the peer airports (and 
how they were selected). Subsequent sections compare these peer airports with SeattleTacoma 
International Airport in terms of the: 
1.  Commercial ground transportation services offered to the travelling public 
2.  Business structures (or operational models) employed and the fees charged 
3.  Responsibilities of and resources available to the landside/parking departments
4.  Operating budgets of these departments and the revenues they collect or manage
5.  Facilities used by commercial vehicles dropping off and picking up airline passengers 
6.  Regulation of TNCs and peertopeer rental car businesses 
The final sections of this report, prepared by Port staff, describe (1) the current commercial ground 
transportation providers at the Airport and their specific business models, and (2) the key constraints on 
commercial ground transportation operations at the Airport.

DEFINITIONS 
The following paragraphs define technical terms used in subsequent sections of this report:
Commercial ground transportation  Rubbertired publicly and privately operated transportation 
service transporting customers to/from airports including taxicabs, limousines, transportation 
network companies (TNCs), sharedride vans, courtesy vehicles, chartered buses and vans, but 
excluding rail service and parking shuttles, rental car shuttles, or other buses operated by or on 
behalf of the Airport. 
Costrecovery fee  A fee charged to commercial vehicle operators doing business on an airport 
(i.e., picking up passengers) which allows the airport owner to recover the costs of providing, 
operating, and maintaining the roadways, curbsides, hold areas, and other facilities used directly by 
the commercial ground transportation operators.
Courtesy vehicle or courtesy shuttle  Doortodoor, sharedride transportation provided by the 
operators of hotels/motels, rental car companies, parking lots, and other businesses solely for their 
customers, and with the cost of such service considered to be incidental to the primary service 
offered the customer.
Deadhead trip  A nonrevenue trip which occurs prior to picking up a customer or after dropping 
off a passenger. 
Dwell time  The total time a vehicle spends at the terminal curbside while waiting for a passenger 
to arrive or to actively load or unload. 
Exclusive Provider  A contract (frequently referred to as a concession contract) between an airport 
operator and a commercial ground transportation business under which the airport provides the 
company certain rights or privileges (e.g., the exclusive right to offer a specific transportation service 
or use designated areas of the airport) and in turn the exclusive provider or concessionaire agrees 
to pay the airport a fee which frequently involves a minimum annual guarantee (MAG) amount 
and/or an amount that reflects the volume of airportrelated business conducted by the company 
(e.g., a percent of gross revenues).
. 
Hold area  An area designated for use by commercial vehicles such as taxicabs, limousines, shared
ride vans, and buses/vans to wait in (or stage) until they are called to the curbside. Also referred to 
as staging area, hold lot, or holding area. 
Improper solicitation Improperly or illegally offering transportation services to airline passengers 
such as licensed and unlicensed limousine drivers (or their representatives) soliciting business from 
passengers who have not made prior arrangements for such service from the driver or company.
Licensed enforcement officer (LEO) A police officer monitoring Airport curbside facilities who is 
capable of issuing tickets for moving violations and arresting offenders. 
Limousine  Transportation service offered in town cars or luxury vehicles, most frequently on a 
prearranged basis, where the provider is compensated based upon the length of time the vehicle is 
hired regardless of the number of passengers transported or distance travelled. At some airports 
ondemand limousine service is available.

SeattleTacoma International Airport                                                              2

Minimum annual guarantee (MAG)  The minimum fee or amount that a business, concessionaire, 
or exclusive provider agrees to pay on an annual basis regardless of the revenues collected or 
business volume conducted. A similar fee may instead be assessed on a monthly basis as a minimum 
monthly guarantee (MMG). 
Ondemand service  Transportation service (e.g., taxicab service) that is provided in direct 
response to a customer's request via telephone, street hail, or other form of communication as 
opposed to prearranged transportation service. At an airport, ondemand services are available on 
a walkup basis at the curbside without prior arrangement or interaction between the customer and 
the provider. 
Owner/operator  An individual who both owns and operates a vehicle (e.g., a taxicab driver who 
owns a taxicab and drives the vehicle). Frequently owner/operators may operate a vehicle as a 
franchisee or as part of a fleet owned/controlled by others. 
Peertopeer  Services that are shared among users rather than owned by a company 
Prearranged service  Transportation service (e.g., limousine, transportation network company, or 
bus/van service) that is provided in response to a prior request from a customer via telephone, 
company provided smartphone application, or other method as opposed to ondemand service that 
is available on a walkup basis. Often the transportation service is required to have an electronic 
receipt or waybill showing the customer's name, pickup point, party size, destination, and arrival 
time, or other details depending on the type of transportation service. The precise definition of 
prearranged varies from community to community.
Privilege fee  As used in this report, a fee charged commercial vehicle operators that reflects the 
overall business benefits the commercial ground transportation operators receive and privileges 
they enjoy as a result of the presence of the entire airport and from the operators' access to the 
traveling public. Typically such fees are calculated based on the volume of airportrelated business 
conducted by the operator. 
Scheduled service  Fixed route transportation operated at set headways or departure times 
Sharedride service  A service providing doortodoor transportation for multiple customers or 
parties to or from an airport whereby each passenger pays a predetermined fare regardless of the 
number of passengers transported or distance travelled. The service, most commonly provided in 8 
to 12 passenger vans, may make multiple enroute stops and may be available on a walkup or pre
reserved basis. 
Taxicab  A vehicle  typically a sedan or van  providing nonstop, doortodoor transportation for 
a single party (one or more passengers) between locations of the passenger's choice with the fare 
established based upon a taximeter or zone system regardless of the number of passengers 
transported. The precise definitions for taxicabs, taxicab companies, and taxicab drivers vary from 
community to community. Taxicab service at airports can be classified as ondemand taxicabs 
available to walkup customers, or prearranged/belledin taxicabs that are serving customers who 
have made prior reservations. Prearranged (e.g., personals) or belledin taxicabs may be licensed 
by a jurisdiction or regulatory authority other than one regulating ondemand taxicabs at the 
airport.

Thirdparty management contractorA qualified business, retained by an airport operator to 
provide and oversee, at the airport's direction, specific services (e.g., management of parking 
facilities) and which is reimbursed for labor hours they furnish and other authorized expenses they 
incur.
Traffic control officer (TCO)  An enforcement officer capable of issuing tickets for nonmoving 
violations but not arresting an offender 
Transportation network company (TNC) A business that connects its affiliated drivers who, using 
their personal vehicles, transport customers desiring doortodoor transportation and who have 
requested this service using the businesses' proprietary smartphone application. The fare is 
typically established based upon time and distance traveled. Service may be nonstop or shared 
with another party depending on the type of service selected. 
SELECTED PEER AIRPORTS 
In cooperation with Airport staff, fifteen airports were selected for comparison with SeattleTacoma 
International Airport. These airports, which are listed in Table 1, were selected to include airports which:
Serve a similar volume of originating and terminating airline passengers. The volume of originating 
and terminating passengers, which excludes passengers connecting between flights, reflects the 
potential users of commercial ground transportation services. As shown below, SeattleTacoma 
International served about 25.9 million originating and terminating passengers in 2013, the most 
recent year for which originatingterminating airline passenger data are available from the Federal 
Aviation Administration 
Serve a passenger mix similar to that served by SeattleTacoma in terms of trip purpose (business vs. 
leisure passengers) and place of residence (local resident versus nonresident passengers) 
Are operated by either a port or airport authority, as is SeattleTacoma International, or by a city or
county 
Employ a range of commercial ground transportation business structures or operating models 
including those considered to have best of industry practices.

The airport staff responsible for the daytoday management of ground transportation at each of the above 
airports were contacted and invited to participate in a detailed telephone survey. Surveys were completed 
with fourteen airports; representatives from Detroit Metropolitan Wayne County Airport (DTW) did not 
respond to requests to participate in the survey.
The resulting survey data were supplemented with data LeighFisher gathered during the conduct of the 
forthcoming Airport Cooperative Research Program Report 146 (Commercial Ground Transportation at 
Airports: Best Practices) and other data contained in LeighFisher's files.
COMPARISON OF OVERARCHING GROUND TRANSPORTATION STRATEGIES 
Airports have a variety of overarching strategies that guide their decisionmaking processes. As shown in 
Figure 1, the primary strategies the peer airports consider when making decisions regarding ground 
transportation operations were customer service (11 of 15 peer airports) and revenue generation or cost 
recovery (8 of 15 peer airports). Other important considerations cited include maintaining efficient 
operations by minimizing traffic congestion, ensuring safety and security for customers, and maintaining 
high levels of accessibility to the airport.

Figure 2 summarizes the extent to which environmental and customer service initiatives are incorporated 
into ground transportation agreements or rules and regulations. Three of the peer airports (PHX, SFO, and 
YVR) place a high importance on environmental initiatives or sustainability. PHX and SFO both require 100% 
alternative fuel vehicles for at least two modes of commercial ground transportation. YVR previously 
provided discounted permit fees for alternative fuel vehicles, but ended this incentive program in 2014 with 
a taxi fleet that is more than 75% alternative fuel. YVR also places a strong focus on sustainability overall. 
PDX considered encouraging alternative fuel vehicles; however, without any incentive program the fleet mix 
is already more than 80% green. BOS, DEN, and IAD offer a discounted permit fee to vehicles using 
alternative fuels, with IAD's applying only to hotel/motel courtesy vehicles. 
Customer service is an important component of ground transportation agreements, rules, and regulations at 
seven of the airports. Common customer service initiatives include requiring all drivers to complete a 
customer service training program, implementing higher vehicle and driver standards than required by the 
local regulator, requiring that ground transportation operators accept credit cards and process them in a 
secure manner, and limiting the age or mileage of vehicles that can be used to provide service at the airport. 
MSP and PDX each have a specific customer service program outside of these common customer service 
initiatives. At MSP, the airport overall sets Widely Important Goals (WIGS). Specifically, the MSP ground 
transportation staff have a goal to create a memorable moment every day (e.g., by approaching a lost 
passenger and asking if he or she needs help finding their ground transportation).

At PDX, the ground transportation operators participate in the airport's "PDXpectations" initiative and are 
educated on the five guiding principles (be knowledgeable, be friendly, speak with body language, be 
respectful, be proactive). Prizes are given out in the hold lot several times per year to encourage drivers to 
approach a booth where customer service handouts outlining the PDXpectations are distributed at that 
time. Airport staff meet with all managers/owners of companies to discuss the PDXpectations. There is also 
a reward program that allows a driver recognized by a customer for good service to be eligible to receive a 
plaque, be recognized by airport management, earn a free lunch, and be entered into a drawing to attend 
an annual dinner. 
COMPARISON OF AVAILABLE COMMERCIAL GROUND TRANSPORTATION SERVICES 
The types of ground transportation services offered at each of the peer airports are summarized in Figure 3. 
All airports provide ondemand taxicab service and prearranged limousine services, and all but YVR offer 
sharedride service. Most airports allow nonlocal or noncontracted taxicabs (i.e., belledin taxicabs) to pick 
up prearranged customers at the airport if the driver obtains a permit and pays the required fees, whether 
an annual permit or occasional use/day pass. At most airports these taxicabs are considered to be pre
arranged services like limousines and regulated as such, rather than being allowed to use the same boarding 
areas or pay the same fees as taxicabs. Some airports such as FLL, MIA, and MSP do not allow outside 
taxicabs to pick up at the airport on either an ondemand or prearranged basis. 
Four of the peer airports have established permits for transportation network companies. At IAH there is 
only one operator (Uber), at DEN and PDX there are two operators (Lyft and Uber), and at SFO there are four 
TNCs (Lyft, Sidecar, Uber, and Wingz). Five airports have agreements in place with peertopeer rental car 
companies such as FlightCar or RelayRides. All five airports classify these operators as offairport rental car 
companies. Four other airports do not yet have agreements in place with any peertopeer rental car 
companies, but have either had discussions with company representatives about operations beginning or 
are aware that the companies are currently operating without an agreement in place.

COMPARISON OF BUSINESS STRUCTURES AND BASIS OF FEES 
General pros and cons of business structures 
There are three basic types of business arrangements (or models) that airports use with commercial ground 
transportation companies. These are: open access, restricted or exclusive access, or a hybrid blend of these 
two. Airports typically use an open access model for their business relationships with all courtesy vehicles, 
prearranged limousines, scheduled vans/buses, and charter vans/buses. Airports may use either an open or 
an exclusive (or semiexclusive) model for their business relationships with taxicabs, sharedride vans, and 
ondemand limousines.
Each model has its advantages and disadvantages. The key differences are (a) the airport's ability to control 
the customer experience and operations, including vehicle and driver standards, (b) the amount of staff 
effort required to implement and oversee operations, and (c) the amount of competition among companies.
Open Access. With an open access system any vehicle having a valid permit issued by the local regulatory 
agency may serve the airport. This allows for greater competition among operators. This competition is the 
key benefit of an open systemall licensed companies have the opportunity to serve the airport. However, 
an open system frequently leads to an oversupply of taxicabs or sharedride vans. An oversupply of taxicabs 
frequently leads to reduced taxicab driver income, reduced motivation for the drivers to properly maintain 
their vehicles, and reduced customer service. As a result, an open system requires increased effort by 
airport staff to ensure that drivers and their vehicles comply with the airport's minimum standards and its 
rules and regulations. Enforcement requires greater staff effort because (a) penalties are limited to 
Comprehensive Review of Commercial Ground Transportation Operations 
SeattleTacoma International Airport                                                              9

monetary fines or service suspensions, and (b) staff, particularly those at large airports, must oversee the 
operation and compliance of hundreds of drivers and their vehicles. Airport staff may also need to 
implement measures to balance the supply of taxicabs with customer demand for service. These measures 
include rotation systems or closing the hold lot at times.
Exclusive Access. With an exclusive (or semiexclusive system) an airport awards a contract to one or several 
companies and only this company may pick up customers at the airport. These contracts are awarded 
through a competitive bid or proposal process. The selected concessionaire(s) is typically responsible for 
daytoday operations including vehicle dispatching from the hold area, curbside operations, and staging 
area management; furnishing the communication and other equipment needed to dispatch vehicles and 
oversee vehicle queues; ensuring the appropriate balance between customer demands and the number of 
waiting vehicles; providing an adequate number of waiting vehicles at all times including during inclement 
weather or irregular operations; and, ensuring that service is provided using vehicles and drivers that meet 
or exceed the standards set forth in their proposal. Compared to an open access contract, enforcement 
requires significantly less effort from airport staff because (a) the airport has a contractual business 
relationship with the ground transportation provider, rather than a regulatory one, and (b) the airport is 
interacting with a single ground transportation provider(or typically fewer than three ground transportation 
providers) rather than hundreds of individual drivers. Customer service is enhanced because companies 
competing for the concession contract are incentivized to propose levels of service that exceed the airport's 
minimum standards.
The major disadvantage of an exclusive or semiexclusive access model is that some properly licensed 
companies will not be selected and these companies will be precluded from conducting ondemand business 
at the airport, and thus denied a business opportunity. A second disadvantage is that if one company is 
awarded the contract, when there is a recompete for the contract the incumbent will have a perceived 
advantage over its competitors, assuming the incumbent has been performing satisfactorily.
Typically companies that are awarded semiexclusive concession contracts allocate the customers using a 
predetermined method (e.g., based upon the number of authorized taxicabs). However, at some airports 
individual taxicab contracts are awarded by terminal building or terminal curbside (e.g. TPA), and individual 
sharedride van services may be awarded by geographic area.
Another practice to allow greater opportunities for small or disadvantaged businesses is to award contracts 
to a driver collective or consortium (such as the contract previously awarded to SITA at SEA and now in place 
at Sacramento International Airport), where multiple smaller independent owner/operators agree to work 
collaboratively together as one group, creating a fleet large enough to serve the airport.
Ondemand taxicabs 
Best practice is typically to have a closed ondemand taxicab system. This is due to the benefits described 
previously including a better experience for customers, higher incomes for the drivers, and a system that is 
easier to manage for airport staff. Figure 4 summarizes the taxicab systems at the peer airports. Of the peer 
airports, eight have an open taxicab system. This includes PDX where all taxicabs are allowed to operate at 
the airport but only every other day (a rotation system). Of the six peer airports with a closed system, BWI 
has a single concessionaire, TPA has two concessionaires, and both IAD and PHX have three concessionaires. 
YVR is unique in that the airport decides on the number of taxicab permits needed, then releases a miniRFP 
for the number of new permits needed to reach that limit. In total there are currently sixteen companies 
who have contracted with YVR in this way. DEN is also unique, as there are only five taxicab companies 
licensed by the local authority, thus each company is allocated a percent of the available permits based on 
the proportion of their business in the city as a whole. It is then up to the companies to decide which drivers 
may use those permits and pick up passengers at the airport on a given day.

When asked what they would change about ground transportation operations at their airports if anything 
were possible, two of the eight peer airports with open taxicab systems said they would prefer to operate a 
closed ondemand taxicab system with only one or a few companies if there was support from 
management. Implementing a closed taxicab system can be a difficult task for airports that must seek 
approval from a City Council or local commission, as airport management will likely face political opposition 
from some taxicab drivers and companies.

Figure 5 summarizes the fees paid by, annual revenues received from, and length of the agreements with 
ondemand taxicabs at the peer airports. The chart also describes how the fees were originally determined, 
when known by airport staff. At some airports, trip or permit fees have been in place without being updated 
for many years, particularly at the open access airports. The majority (nine) of the peer airports determine 
their fees using a cost recovery analysis  determining the fees that would be necessary to fully recover the 
costs associated with managing the taxicab service, including providing and maintaining the curbsides, 
dispatching and other equipment, staging areas, and the roadways and other facilities used by the taxicab 
operators. At airports with a closed system, the companies awarded the concession contract are typically 
required to pay a MAG, a pertrip fee, or a percent of gross revenues when they submit their bid for the 
concession contract. Other airports negotiate with the contracted taxicab concessionaire(s) to determine a 
fee amount that is acceptable to both the provider(s) and the airport. 
Many airports will at times have insufficient taxicabs waiting at the airport to pick up ondemand 
passengers, particularly when there are irregular flight operations, severe weather that impacts the 
condition of the roadways such as ice or heavy storms, or when there are unusually high demands for 
taxicabs elsewhere in the community. Figure 6 shows the methods used by the peer airports to manage 
customer wait times and ensure the availability of taxicabs during these times. At airports with a closed 
system and a formal agreement with the taxicab operator(s), the taxicab companies (the concessionaires) 
have a contractual obligation to pick up waiting passengers within a prescribed amount of time, ranging 
from three minutes at TPA to twenty minutes during offpeak times at BWI. PHX has a customer wait time 
limit of 5 minutes. If a customer must wait longer and the company does not have at least 85% of its taxicab 
fleet in operation, then it is assessed a fine of $295 per occurrence. At DEN there is no prescribed time limit 
for customers waiting to be picked up, but if there are long lines and any of the five companies are 
consistently found to not be providing sufficient taxicabs, then the airport may reallocate some of their 
permits to another company. The airports reporting that a lack of taxicabs is not an issue (e.g., IAD and IAH) 
also report having excessive numbers of waiting taxicabs during most hours. 
At most of the other airports not previously mentioned, if there are insufficient taxicabs then the airport 
taxicab dispatcher will contact the companies and alert them that additional taxicabs are needed. BOS uses 
a unique system where the airport taxicab dispatcher updates a Twitter account to alert licensed taxicab 
drivers to how many taxicabs are currently in the airport taxi pool, whether additional taxicabs are needed, 
and what time the last flight is scheduled to arrive if there have been delays. This provides the drivers with 
uptodate information that they can check from any location, allowing them to make an informed decision 
about whether to serve the airport at that time.

Ondemand limousines 
Only four of the peer airports (BWI, FLL, PDX, and YVR) have ondemand limousine contracts. PDX is 
contracted with three companies; however, they are currently reviewing their contract and are unsure 
whether it will be renewed. Those three companies currently pay the airport a trip fee of $3.00 per pickup. 
The single contracts at BWI and FLL are operated by the same companies that hold the sharedride contracts 
at the airports. At BWI the operator pays the greater of 9% of gross revenues or a minimum annual 
guarantee (MAG) of $100,000. At FLL the contract is combined with the sharedride agreement, with a fee of 
$0.461 per deplaned passenger with a MAG of $500,000 from both the ondemand limousine and shared
ride operations. YVR was unable to share the details of their ondemand limousine contract. 
Until recently PHX had an ondemand limousine contract; however, when the contract expired airport staff 
determined that it was not viable to renew the contract because (1) the contracted company was struggling 
to make their required payments, (2) the amount of curb space allocated to the service did not seem to be 
warranted, (3) conflicts between the ondemand limousine drivers and taxicab drivers, and (4) the service no 
longer seemed to be needed due to the recent improvements in the quality of taxicab service. The previous 
concessionaire is now operating on a prearranged basis instead, and the airport provided the company with 
advertising on the airport website and in the terminal to assist them during the transition period. 

Comprehensive Review of Commercial Ground Transportation Operations 
SeattleTacoma International Airport                                                             14

With the advent of TNCs and their related services such as UberBlack (provided in both personal cars and 
licensed limousines), there is less need for an airport to offer ondemand limousine service to passengers.
This is because (1) customers can now select from traditional ondemand taxicabs, prearranged limousines 
including UberBlack, and TNCs, (2) it is questionable as to what advantages airports can offer a prospective 
ondemand limousine provider other than the ability to have a waiting vehicle parked at the curb, and (3) 
the value of the concession contract appears to have been diminished, and in the view of some, is no longer 
financially attractive. 
Ondemand sharedride service 
Best practice for sharedride service is to have a closed system where the airport has a contractual 
(concession) agreement with one or a few companies (an exclusive or semiexclusive concession). Of the 
peer airports, seven have an exclusive agreement with one sharedride provider and one has an agreement 
with two providers. YVR does not have sharedride service. The other five airports that responded to the 
survey have an open access system. A summary of the type of agreements and customer service standards 
for sharedride operators at each airport is provided in Figure 7.
With a closed system, it is easier to implement and enforce customer service standards such as maximum 
customer wait times, secure credit card processing, vehicle age limits, and driver training. Eight of the 
airports have maximum customer wait times, typically between 20 and 30 minutes. Many of the airports 
require that the sharedride providers accept credits card, but only IAD, MSP, and PHX specify the method of 
credit card processing in their contracts to ensure transactions are conducted securely. At other airports 
such as MIA, the company requires drivers to use secure credit card processing without any requirement 
from the airport. 
Six of the airports have an age requirement for sharedride vehicles. IAD and SFO have a maximum age of 
four model years, and MIA and MSP have a maximum age of five years. BWI and PHX both limit the vehicle 
age at the start of the contract, but do not have a maximum age limit. At PHX 75% of the fleet must be new 
at the start of the contract, with the other vehicles no more than 2 years. The PHX contract is for five years, 
with one fiveyear option. BWI requires that all vehicles be no more than 5 years at the start of the fouryear 
contract. 
Only three of the peer airports have measures in place to encourage or require sharedride operators to use 
alternative fuel vehicles. PHX and SFO both require that 100% of the sharedride fleet use alternative fuels, 
with PHX using propane and SFO using CNG. DEN offers a reduced trip fee incentive for operators choosing 
to use alternative fuel vehicles.
Other customer service initiatives referenced by the airports interviewed include training programs (BWI 
and MIA), providing a way for customers to give feedback through comment cards or another method (MIA, 
MSP, PHX), driver and vehicle appearance standards (IAD, PHL), and the ability for the customer to make 
reservations and payments for the sharedride service online (PHX).
Figure 8 summarizes the basis and amounts of the sharedride fees and, when available, a recent annual 
amount received. Six of the peer airports (BOS, DEN, MSP, PDX, PHL, and SFO) determine their fees based on 
a costrecovery analysis, and four of the airports' sharedride fees are based on bids received by the 
operators (BWI, MIA, PHX, and TPA). At the four airports with bids, both MIA and TPA originally set a 
minimum bid amount. 
When asked what they would improve about the ground transportation systems at their airports, two 
airports indicated that the sharedride system would be an area for improvement. Both were airports with 
open sharedride systems who would prefer to have a closed system with fewer operators, and in one case,

have a company with better brand recognition for customers. In both instances local regulations and politics 
were the limiting factor on those airports being able to do so.

NEW INDUSTRY PROVIDERS 
Recent changes in the industry due to the rise of the sharing economy have resulted in two new types of 
companies entering the ground transportation/rental car business at airports. These new services include 
transportation network companies (TNCs) where a passenger uses a smartphone application to connect to a 
driver using their personal vehicle, and peertopeer rental car companies, where a customer rents an 
owner's personal vehicle while it is not in use. The most wellknown of these companies are UberX and Lyft 
for TNCs and FlightCar and RelayRides for peertopeer rental car companies.
Transportation Network Companies 
Airport staff at all of the peer airports except YVR reported that TNCs are operating in their area, although 
most are doing so without the airports' approval. Only four of the airports (DEN, IAH, PDX, and SFO) have a 
permit in place for TNCs. PHX is currently in discussions with the TNCs to develop a TNC permit, but some 
TNC drivers have obtained a prearranged operator permit to operate at the airport. IAD has developed a 
draft permit which is being reviewed by their board.
The process for a TNC to begin operations at each of the four airports with permits is similar. The company 
must first obtain an operating permit from the local regulatory authority, then complete an application for 
an airport permit, agreeing to pay fees and comply with the airport's rules and regulations, including 
displaying the company's trade dress. At SFO there was a onetime activation fee to cover the unpaid fees 
the companies incurred prior to agreeing to sign the airport's permit. IAH is unique in that in addition to the 
company signing an airport permit, each driver must also be licensed by the City of Houston and receive an 
airport permit by showing proof of their City registration. 
Table 2 summarizes the fees charged to TNCs at the four airports with TNC permits. At all four airports, the 
trip fee was originally determined based on the existing trip fee for other operators. At DEN and PDX, 
however, a trip fee is charged for both drop off and pick up, even though other operators are only charged 
for pick up. At PDX this is because taxicabs and limousines must pay an annual vehicle permit fee in addition 
to the company permit, which TNCs are not required to pay. At SFO limousines also pay for trips on a pick up 
and drop off basis. 
At all four airports, TNC drivers are required to stage outside of the main terminal area. Table 3 shows the 
location where TNC drivers must wait for, pick up, and drop off customers. At all of the airports, the TNCs 
wait in a location separate from the taxicab holding area. The drivers at DEN wait in one of two remote 
parking facilities infrequently used by customers except during peak travel weeks. At IAH, PDX, and SFO 
there are designated holding areas for commercial vehicles or TNCs only with minimal amenities. 
The TNCs at each of the four airports currently selfreport their trips and associated fees. SFO is able to 
verify the trips using software airport IT staff developed. The software also enables airport enforcement 
staff to see the TNC vehicles currently at the airport in realtime, the company they are operating for (as 
some drivers work for more than one TNC), and information about the vehicle's trip history including how 
long they have been on airport property and whether the driver dropped off a passenger. PDX is currently 
developing their own version of this enforcement software. In the meantime, PDX has audited the 
companies and found them to have complied with their reporting requirements.

Both DEN, IAH, and SFO reported that the main challenge in managing the TNCs has been in educating the 
drivers on how to operate properly while on the airport (i.e., how the airport "works") and ensuring they 
comply with the rules and regulations, particularly given the high driver turnover rate and use of non
professional drivers. SFO also cited concerns about the large number of TNC vehicles operating at the airport 
and congestion on the roadways. PDX did not have any complaints about their TNC operations. 
The other peer airports where the TNCs are operating without a permit in place were also asked what 
challenges they have faced with regard to the TNCs and how this new service has impacted other 
commercial ground transportation operations. At these airports the main challenge is in enforcing the 
airport's current regulations against the companies who are operating there illegally. In Miami, the airport 
and city combined have issued over $2 million in fines. PHX has also been issuing citations to unpermitted 
drivers and had Uber implement a geofence to limit the areas where vehicles can wait for a customer. IAD 
also had issues with TNC drivers dwelling in prohibited areas.

The peer airports found mixed impacts of the TNCs on airport taxicab operations. PDX found that taxicab 
trips increased yearoveryear but at a slower rate than in previous years (23% compared with 11% in 
2014). DEN and IAH did not report any impacts to the taxicab providers, and at PHX taxi trips were up 10% 
over the previous years. At IAD there was a decrease in both the inbound (6%) and outbound (3%) taxicab 
trips, however. SFO also found that inbound taxi trips were affected more than outbound trips, which 
increased yearoveryear.
There were also mixed results for the impact on other commercial ground transportation operators. At DEN 
there has been an impact on both sharedride providers and limousine operators, many of whom are now 
using application based software similar to the TNCs. At FLL the sharedride/ondemand limousine operator 
has reported a decrease in passengers, although the company is not required to report trip data to the 
airport. Similarly, the sharedride operator at MIA has also reported a decrease in business, but the airport 
has not seen much of an impact on either the sharedride or limousine operators. At PDX the number of 
limousine and sharedride trips have remained about the same as in previous years despite passenger 
growth at the airport. Similarly, sharedride passenger numbers were flat yearoveryear at PHX.

PeertoPeer Rental Car Companies 
The two main peertopeer rental car companies (FlightCar and RelayRides) typically have very different 
business models at airports. FlightCar typically operates off of the airport property, often at a nearby off
airport parking or hotel/motel site. Customers can use the parking or hotel operator's courtesy shuttle to 
travel to and from the airport terminal or consolidated rental car facility. Owners leave their vehicles at 
FlightCar's lot and receive free parking while their vehicle is available to be rented by customers. Their 
competitor, RelayRides, more often leaves the vehicle owner to arrange for pick up or drop off of the vehicle 
with the customer directly. Many of the vehicles advertised as available at an airport on their website are in 
fact located at the owner's home or other location in the area surrounding the airport. In these instances, 
the airport does not have an agreement with RelayRides. Some drivers will meet or drop off passengers at 
the airport or arrange to have their vehicle dropped off in an airport parking facility however.
At SFO both FlightCar and RelayRides operate using the typical FlightCar business model. The airport 
considers these companies offairport rental car providers and has an agreement in place accordingly. 
Similarly, the other four airports that have agreements in place with a peertopeer rental car company (all 
currently with FlightCar) also consider the company to operate as an offairport rental car company. At all 
four of these airports (BWI, DEN, PDX, and PHX) the airport's business relationships with these peertopeer 
rental car companies are managed by the same airport staff responsible for management of the traditional 
rental car companies rather than the ground transportation staff responsible for oversight of commercial 
ground transportation services. 
OVERVIEW OF AIRPORTS' GROUND TRANSPORTATION ORGANIZATION AND RESOURCES 
Table 4 summarizes the staff resources available to the airport sections or departments responsible for 
oversight and management of commercial ground transportation operations. As shown, the number of full 
time equivalent (FTE) staff varies from two or fewer (BWI, FLL, IAD, and YVR) to over 100 (IAH and MIA).
Several of the airports, particularly those with open taxicab systems and limited staff resources, employ 
thirdparty management contractors to assist with the oversight and management of commercial vehicles 
and curbside operations. Airports employing thirdparty contractors to assist with commercial vehicle and 
curbside operations include DEN, FLL, IAD, PDX, PHL, PHX, and SFO. 
Figure 9 shows the responsibilities of the airport staff responsible for oversight and management of 
commercial vehicle operations. The key differences are which group is responsible for taxicab 
dispatching,vehicle inspections, driver permitting, control of the staging areas, and management of the 
roadways used by private vehicles.

FACILITIES USED BY COMMERCIAL VEHICLES TO DROP OFF AND PICK UP PASSENGERS 
This section summarizes the curbside and other facilities used by commercial vehicles when dropping off 
and picking up airline passengers. Key features considered when contrasting the dropoff and pickup 
facilities of the peer airports are:
1.  Is access to the boarding areas gate controlled? 
2.  Does the airport have more than one terminal? 
3.  Are forhire vehicles, particularly, ondemand taxicabs and sharedride vans, visible from the 
baggage claim exit doors? 
4.  How is the available curb space allocated among users? 
5.  What amenities are available to customers waiting for commercial vehicles? 
This section also addresses holding lots or staging areas and the amenities provided to commercial vehicle 
drivers in these lots. 
Gatecontrolled access to commercial vehicle boarding areas 
Airports place control gates (often AVIactivated gates) at the entry to the commercial vehicle boarding 
areas in order to prevent unauthorized vehicles from entering. Gates can also be placed at the exits to 
monitor vehicle dwell times and support the implementation of fines or dwell time fees to discourage 
excessive dwell times. Thus the use of gates simplifies vehicle management and enforcement. However, 
the ability to have gate controlled roadways depends on the terminal area roadway layout (e.g., having a 
dedicated commercial vehicle roadway and space for vehicle queues which may form at the entry gate). The 
peer airports with gate controlled access to the commercial vehicle boarding area include DEN, MSP, and 
TPA. Access for some but not all commercial vehicles is gate controlled at PHL (forhire vehicles only) and 
PDX (taxicabs only). 
Number of terminals 
Airports with multiple terminals typically have a greater amount of curb length. However, oversight and 
management of multiple curbs requires more enforcement personnel, more taxicab or sharedride 
dispatchers, and allocation of space for each vehicle class at each terminal. Of the peer airports, those with 
multiple terminals (and the number of physically separated terminals) are: BOS (4), DTW (2), FLL (4), IAH (5), 
MSP (2), and PHX (3). 
Visibility of forhire vehicles from baggage claim exits 
Passengers exiting baggage claim expect to be able to easily find waiting taxicabs and the boarding areas 
assigned to forhire and other commercial vehicles. These expectations are a result of airline passengers, 
including those travelling in commercial vehicles, traditionally being dropped off adjacent to the checkin 
area and being picked up adjacent to the baggage claim area. Since most large airports have multilevel 
terminal buildings with checkin lobbies on the upper level and baggage claim areas on the lower level 
airline passengers are typically dropped off on the upper level and picked up on the lower level. This

SeattleTacoma International Airport                                                             24

layoutan upper level dropoff curbside and a lower level pickup curbside for all vehiclesrepresents the 
most common or conventional airport curbside layout.
Examples of airports having conventional twolevel curbside layouts Ten of the selected peer 
airports have twolevel curbside including BWI, BOS, DTW, FLL, IAH, MIA, PDX, SFO, and YVR. At these 
airports, with the exception of BOS and SFO, passengers exiting baggage claim areas can easily see waiting 
taxicabs, sharedride vans, courtesy vehicles, and scheduled buses.
At BOS, three of the four unit terminals (Terminals A, B, and C) have two level curbsides, but the 
fourth (Terminal E) has a single level curbside. At Terminals A and C passengers exiting the baggage 
claim area can see the boarding areas for all commercial vehicles. However at Terminal B, due to a 
lack of curbside capacity, the taxicab and limousine boarding areas were recently moved from the 
lower level curbside to the Terminal B garage located on the opposite side of the curbside roadway.
Passengers seeking taxicabs must exit the baggage area and walk across the curbside roadway to the 
Terminal B garage. Taxicab and limousine boarding positions, which occupy an entire level of the 
garage, are configured in two rows of angled, pullthrough spaces. This space layout (1) improves 
customer throughput/reduces customer wait times as multiple taxicabs or limousines can be 
boarded simultaneously, (2) provides for covered/weather protected boarding positions, (3) allows 
for efficient oversight and control by Airport staff, and (4) minimizes conflicts between vehicles and 
pedestrians. 
At SFO sharedride vans, transportation network company vehicles, and courtesy vehicles (except 
those serving offairport rental cars which are required to use the consolidated rental car center) are 
required to both drop off and pick up passengers on the upper level due to a lack of curb space 
capacity.
At IAH passenger dropoff and pickup areas are located on two levels at Terminals A, B, C, and E.
Terminal D only has a dropoff curbside as it only serves departing international passengers. At 
Terminals A, B, and C the pickup curbsides are adjacent to the baggage claim area, but at each 
terminal there are three separate pickup curbsides  one each on the south, north, and west 
facades of the terminal building. Each curbside serves a different ground transportation service 
(e.g., private vehicles on the north curb, rental cars and taxicabs on the west, and courtesy vehicles 
on the south). However, because of the roadway design, some vehicles stop with the driver's side 
adjacent to the curb (considered "wrong way" loading as passengers must board the vehicle while 
standing in an active traffic lane). Because IAH has 15 individual curbside areas, each physically 
separated, more staff are required to control traffic and enforce these curbsides than a conventional 
curbside.
Airports having curbside layouts with three or more levelsDEN, IAD, and MCO. A few U.S. airports 
have more than two curbside levels include DEN, IAD, and Orlando International (MCO). At these airports all 
vehicles are required to dropoff passengers on the upper level (adjacent to ticketing). Commercial vehicles 
are required to pickup passengers on one of the two remaining levels the middle level at DEN, and the 
ground levels at IAD and MCO. At MCOwhich was not one of the selected peer airports because of the 
large proportion of nonresident airline passengersthe threelevel curbside configuration is replicated on

both sides of the terminal building, and supplemented by a fourth boarding area beneath the terminal 
building restricted for use by prearranged limousines that have been inspected by security staff.
TPA has curbsides on two sides of the terminal building (the red and blue sides) each having separate 
passenger dropoff and pickup areas. At TPA the dropoff curbside used by all vehicles and the pickup 
curbside used by private vehicles and limousines are traditional linear curbsides. These linear curbsides are 
supplemented by four surface parking lots which are reserved for use by taxicabs, sharedride vans, and 
courtesy vehicles. The surface parking lotsreferred to as Quad Lots as they are located in each quadrant 
of the buildingare immediately adjacent to each end of the baggage claim areas. 
Airports having nontraditional curbsidesPHL, PHX, MSP, and DTW. PHL and PHX have non
traditional curbsides, but their layout permits passengers exiting the baggage claim areas to easily see 
waiting taxicabs, sharedride vans, courtesy vehicles, and scheduled buses.
At PHL the checkin lobby and baggage claim areas are located in two separate buildings for each of the five 
terminals. These buildings are separated by a railroad track with elevated walkways connecting the aircraft 
gates/departure terminals and the baggage claim building. All vehicles dropoff passengers on the 
departures road adjacent to the checkin lobbies. There are two arrivals curbsides, one on either side of the 
baggage claim building, with the south side used by private vehicles and courtesy vehicles, and the north 
side used by forhire vehicles. 
At PHX there are curbside roadways on both sides of Terminals 3 and 4. Terminal 3 has a single level 
curbside. Boarding areas for taxicab and rental car shuttles are provided on both the north and south curbs 
while the boarding areas for all other commercial vehicles are located only on the south curb. Terminal 4 
has a twolevel curbside with upper levels on both sides used for dropoff by all vehicles, and a lower level 
on both sides used for pickup by all vehicles. At the lower level there is an inner and outer curbside with 
private vehicles using the inner curbside and taxicabs, rental car shuttles, and courtesy vehicles using the 
outer curbside. 
As described below the commercial vehicle boarding area is not adjacent to or visible from the exits from 
the baggage claim areas at MSP and at DTW's McNamara Terminal.
At MSP passengers board taxicabs, limousines, sharedride vans, scheduled vans, and courtesy 
vehicles from a Ground Transportation Atrium located within a parking structure opposite the 
terminal. Access between the terminal and the Ground Transportation Atrium is provided via an 
underground walkway that passes airline checkin desks located in the ground transportation 
center.
At DTW both terminals have Ground Transportation Centers, where passengers board taxicabs, for
hire vehicles, and courtesy vehicles. The Ground Transportation Center is located in a parking 
structure at the McNamara Terminal.

Allocation of available curbside space 
The peer airports consider multiple factors when allocating the available curb space on the inner or outer 
roadways or along the length of the curbsides among the commercial vehicles. The factors include:
Passenger and vehicular safety. Provide adequate curb space for maneuvering vehicles (especially large 
buses and coaches), minimize the volume of passengers crossing roadways, separate private and 
commercial vehicles, and enforce dwell times
Customer expectations. Locate services that customers expect to find at the curbside (e.g., ondemand 
taxicabs) in visible locations 
Use of public transportation. Provide convenient boarding areas for scheduled buses/vans and public 
transit services. Some airport operators (e.g., BOS and SFO) assign these services to the curbside areas 
immediately adjacent to the terminal unless prevented from doing so by vertical clearance, structural 
loads, or roadway widths. At MIA, shuttles must use the outer roadway due the lack of bypass lanes on 
the inner roadways. Conversely, at PHX these vehicles use the outer curbsides, in part to enhance traffic 
operations. 
Nonairline revenues. Allocate the more visible and convenient curbside spaces to services that generate 
significant revenues (e.g., onairport parking and rental car shuttles) 
Competition among ground transportation operators. Separate competing operators (e.g., ondemand 
taxicabs, sharedride vans, and limousines) while attempting to provide them with equivalent access to 
deplaning airline passengers. Airports also attempt to distinguish between on and offairport parking 
courtesy vehicles.
Separation of private and commercial vehicles. Improve ability to control and enforce pickup areas by 
separating private and commercial vehicles, and if space is available, providing separate boarding areas 
for each type of commercial ground transportation service 
Examples of curbside space allocations: 
Due to the City of San Francisco's "Transit First" policy, priority is given to curb space for HOVs at 
SFO 
Due to curbside capacity constraints the upper level curbside is used for both dropoff and pickup 
by most hotel/motel courtesy vehicles at MIA and by all courtesy vehicles, TNCS, and sharedride 
vans at SFO
At MIA and SFO's International Terminal, courtyards are reserved for the use of charter buses (e.g., 
cruise ship buses) 
Amenities provided waiting passengers 
Most of the peer airports provide bus shelters and benches for passengers waiting for commercial vehicle.
However several airports provide additional amenities: 
At MSP the Ground Transportation Atrium contains a heated/air conditioned seating area, having 
padded chairs, floortoceiling windows to allow waiting passengers to see arriving vehicles, and 
counter space for the regional shuttles 
At TPA there are enclosed, air conditioned waiting areas adjacent to the Quad Lots

There are counter areas for the commercial ground transportation providers available for lease at 
DEN, PHL and PHX. Several of the airports with exclusive shared ride van concession contracts (e.g., 
BWI, FLL, IAD, and IAH) provide or lease counter space to the concessionaire.
At PDX a glass canopy covers all the curbside areas 
SUPPORTING TECHNOLOGIES 
Ten of the peer airports have AVI systems. Those that do not are BWI, IAH (which formerly had one and is 
evaluating reinstalling a system), TPA, and YVR. PDX recently acquired an AVI system which is scheduled to 
be operative by September 1, 2015.
Airports having handheld devices used by curbside staff for enforcement or dispatching purposes and to 
supplement their AVI systems include FLL, IAD, MSP, PHX, and SFO, although IAD report that they never use 
the devices. PHX and IAH IT staff developed their own device while the other airports acquired the device 
through their AVI system vendor. 
Most of the airports rely upon radios or mobile phones to dispatch taxicabs and other vehicles from the 
staging lot to the curbside boarding positions. MSP staff developed a unique software program which 
among other features monitors the position of each waiting taxicab and automatically dispatches the vehicle 
to the boarding area. SFO is in the midst of acquiring a system to monitor both taxicabs and sharedride 
vans. IAD has an automated taxicab dispatching system developed by an outside vendor. At those airports 
having a contracted taxicab or sharedride system the contractor is responsible for acquiring and 
maintaining the dispatch system.
None of the airports surveyed have airport provided mobile phone applications (apps) for arranging forhire 
vehicle trips. 
COMMERCIAL VEHICLE STAGING AREAS/HOLDING LOTS
Table 5 summarizes the capacity and use of the commercial vehicle staging areas. Most of the peer airports 
have one staging lot, but FLL, MIA, MSP, PHL, PHX, and SFO have multiple areas. At IAD and PHL there is a 
remote main holding area and a small stack or lot closer to the terminal. At MIA and SFO there is one area 
for taxicabs and one for all other commercial vehicles. At PHX one area is used primarily by black cars and 
the other area by all other operators.

The reported sizes include all the available staging lots as well as supplemental stacking areas located near 
the terminal. The lot sizes vary from about 150 spaces (PHX) to over 1000 spaces (IAD). The number of 
spaces provided reflect the volume of taxicab business, the number of waiting taxicabs, the average length 
of time the drivers spend in the hold lot (which varies from under 2 hours in BOS to nearly 4 hours at IAH), 
and the availability of convenient sites on the airport. Other information gathered from the peer airports 
includes: 
The travel time from the staging areas ranged from 1 to 10 minutes. Airports with 10 minute travel 
times (e.g., FLL and IAD) were more likely to have supplemental stacking areas.
Generally the staging areas serve taxicabs, sharedride vans, limousines, and charter buses, with the 
areas for taxicabs separated from the other services by fences or barriers. However staging area at 
MIA and SFO are reserved exclusively for taxicabs. Waiting taxicabs park in nosetotail queues at all 
the airports except IAD, MSP, and PHX. Each of these three airports have reader boards that 
indicate each driver's position in the waiting queue, allowing drivers to park their cars in

conventional spaces and avoid the need to move up when preceding taxicabs are dispatched to the 
terminal.
Staff of the peer airports reported that commercial vehicles never or rarely park in adjacent 
communities, and that when they do it is typically not a concern of the local communities. 
Figure 10 presents information about the driver lounges. BOS and SFO reported not having a lounge, and 
FLL's consists of a tent and wood deck. Generally the lounges contain TVs (sometimes provided by the 
drivers rather than the airport), microwaves, and most offer WiFi access. The lounge at MSP is in the rear 
of a convenience store/service station, allowing access to food, beverages, and gas/oil for their vehicles. IAD 
provides a virtual hold lot, allowing drivers to exit the hold lot and monitor their position remotely without 
losing their place in the queue.
Five of the airports provide facilities for meditation, reflection or religious practices. At some this implies a 
quiet area, while others have provided special fixtures (e.g., foot washes).
Six of the peer airports reported that one to two staff were present in the holding area at all times and 
provided some form of office space for these staff. DEN has eight staff (including two from their 
management contractor). 
AIRPORT DESIRED IMPROVEMENTS AND EXAMPLES 
Twelve of the fourteen airports provided examples of airports whose ground transportation systems as a 
whole or a specific aspect of an airport's ground transportation system they found desirable. The twelve 
responses included 28 references to 14 airports. The airport that received the most references was MCO, 
which was highlighted in four responses. SEA and SFO were each mentioned by three others and five 
airports were mentioned by two others. PDX and TPA also selfidentified as having desirable systems, PDX 
specifically for its busing and TPA overall. Another airport called out PDX's taxicab rotation system. 
Of those airports that received multiple references, the references were mostly for different aspects of the 
system. For example, references to MCO highlighted the Mears buses, curbside layout, shuttles, and rental 
car facility (which was outside the scope of the study). Only MSP (taxi system) and DFW (tolling system) 
received multiple references for the same reason. Specifically, other airport staff liked the taxi dispatch 
system and pullthrough curb spaces at MSP. PHX was called out for its handheld devices and likecolored 
taxicabs, and ATL's commercial vehicle loading areas with stall parking and covered walkways was also 
referenced. SEA received references for its rental car facility, taxicab system, covered commercial vehicle 
area, and amount of curb space (from PDX staff). Several of the staff interviewed listed additional curbside 
capacity as a desired improvement for their own airports.

Limitations of Translatable Documents

PDF files are created with text and images are placed at an exact position on a page of a fixed size.
Web pages are fluid in nature, and the exact positioning of PDF text creates presentation problems.
PDFs that are full page graphics, or scanned pages are generally unable to be made accessible, In these cases, viewing whatever plain text could be extracted is the only alternative.
