Exploring the travel behavioral differences for the elderly mobility on public transit

초록

Developing an integrated transportation system has required strategies to improve mobility in public transportation networks. This study aims to construct a route choice model incorporating heterogeneous travel behaviors and suggest policy improvements considering travel behavioral characteristics for the elderly in transportation planning. A stated preference survey has been established to explore the travel behaviors on public transit. The behavioral differences of elderly travelers are compared with young adult travelers by the parameters of travel time attributes. Travel time multipliers are developed to compare the time impedance for the travels on public transit using the concept of willingness to pay. Travelers are reluctant to increase the transfer time for all types, resulting in multipliers ranging from 1.91 to 2.11. The results provide the implications of transport policy for the elderly considering a convenient transfer on the integrated transit system in an aging society.
