CHAPTER 8
Improving Public Transportation
Mode Share for Employees
Chapter 8 describes ways to improve the public transportation mode share for airport employ-
ees. The chapter begins with a discussion of factors that influence employee use of public trans-
portation. Next, the results of a survey of the employee commuting patterns at representative
airports are summarized and key considerations for improving employee public transportation
mode share at airports are presented.
The Objective and the Challenge
Airport employees represent a large potential market for public transportation. As Table 8-1
shows, the average number of daily employees at major U.S. airports can exceed 40,000. There
are a number of challenges, however, to implementing successful public transportation services
for employees at an airport. First, airports are usually located in suburban locations, which can
be difficult to serve with traditional transit services. Second, airports are in operation 24 hours a
day, and many work shifts do not coincide with typical transit schedules. Third, airports have
multiple employers, each of whom has a variety of constraints and regulations regarding shift
timing, parking reimbursement, overtime, etc. Taken together, these challenges can affect
employee mode choice.
Factors That Influence Employee Use
of Public Transportation
Although data on employee transit use are limited, four factors are believed to influence the
mode choice of airport employees:
· The availability of transit service at the employee residences. Is transit service to the airport
reasonably accessible in areas where employees live? In many communities, available public
transportation links the airport with the regional core or major activity centers. Employee res-
idences, however, may be concentrated in other corridors where housing is less expensive and
travel is less congested. Public transportation connections to the airport may not be readily
available in these locations.
· The accessibility of the employee's worksite to transit service. Does the transit service pro-
vide a convenient connection to the employee's final destination on the airport? Many airport
employees work in areas beyond the passenger terminal, such as ramp areas, cargo centers,
aircraft maintenance facilities, and other employment sites scattered around the airport
property.
· The availability of transit during non-traditional work hours. Does the transit service offer con-
venient frequencies of service when employees need to travel to work? Many airport employees
