Est. Total Project Cost:           $580,000 
Est. State and Local Taxes:         $15,000 
ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to (1) proceed with adding
train arrival time displays for the South Loop and Shuttle trains at Seattle-Tacoma International
Airport; (2) procure required hardware, software, vendor services, and maintenance; and (3) use
Port staff for implementation, for a total project cost not to exceed $580,000. 
SYNOPSIS 
Under the Airport NorthStar project, software was developed by Information & Communication
Technology (ICT) to display next train location and arrival times above the train doors in the
north satellite loop train stations. In addition, a textual message function was provided so that 
the Airport Communication Center (ACC) can communicate real time information to travelers. 
This project will expand the new system to the remainder of the train stations including the south
terminal loop and shuttle stations. ICT, Aviation Maintenance, and Port Construction Services
(PCS) resources will complete the project. Total project costs are estimated to be $580,000.
Funding for this project was not included in the 2016-2020 capital budget and plan of finance.
The budget for this project (C800835) will be transferred from the aeronautical allowance CIP
(C800404) resulting in no net change to the Aviation Division capital budget. Recurring
maintenance costs will be budgeted within the ICT and Aviation Maintenance department's
operating budgets. 
BACKGROUND 
In 2015, the NorthStar project included as a component of the early work package at Alaska
Airline's request,displays with train progress information to the north terminal airport train 
stations. This includes main terminal north, the north satellite, and concourse C train stations.

This solution, deployed in April 2016, does not include train progress information for the south
terminal or shuttle trains which include the main terminal south, main terminal north, south
satellite, and concourse B stations. 
PROJECT JUSTIFICATION AND DETAILS 
With increasing passenger flow utilizing SeaTac airport, crowds are becoming the norm rather
than an exception. During peak times, demand for trains can be significant, increasing traveler
anxiety especially after going through security lines at the checkpoint. The display of time to the
next train information can provide a level of assurance that they can safely wait for another train.
In addition, train service reliability may be increased if travelers are not holding doors open. 
Over the next several years, train service interruptions or other impacts will occur as construction
for the new International Arrivals Facility (IAF)  commences. Targeted communications
regarding train service will be important to keep passengers moving. 
Project Objectives 
Improve customer service by displaying a consistent countdown to train arrival at the
south terminal loop and shuttle stations as deployed on the north terminal loop. 
Eliminate discrepancies in customer service information between train locations. 
Enable targeted communications to passengers regarding train service interruptions. 
Scope of Work 
Expand Airport train display software to include south terminal loop and shuttle
locations 
Install eleven (11) displays above doors at the south terminal loop and shuttle station
locations

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Do not expand Train Display System to South Terminal Loop and Shuttles 
Cost Implications: $0 
Pros: 
(1)   Capital is available for other projects. 
Cons: 
(1)  Train arrival and construction related train service interruption notices are not
available for customers traveling to the south satellite or using the shuttle train. 
(2)  There is a discrepancy in the customer service level for passengers using the north
terminal loop trains and those using other airport trains.  This is especially
noticeable in the main terminal north where the shuttle arrives directly across from
the north loop train. 
This is not the recommended alternative. 
Alternative 2  Purchase a vendor developed system to provide train countdown displays 
Cost Implications:  This alternative has been estimated to cost $205,000 more than the
recommended option. 
Pros: 
(1)  An off-the-shelf solution would require less involvement for ICT staff making them
available for other efforts. 
Cons: 
(1)  Existing vendor solutions do not provide limited functionality. ICT has already
developed a feature rich, working system at lower cost. In addition, an off the shelf
system cannot be readily customized, enhanced, or improved. 
This is not the recommended alternative. 
Alternative 3  Expand the train countdown display already developed by ICT to the south loop
and shuttle train stations. 
Cost Implications: The cost for this recommended alternative is $580,000. 
Pros: 
(1)  Passengers will be provided consistent visual information about train arrival time
and other important notifications at all airport train stations. This has been proven to
lessen anxiety and improve passenger flow. 
Cons: 
(1)  Capital is not available for other projects 
This is the recommended alternative.
