| ABSTRACT:Commuting is one of the most basic and important travel activities in metropolitan residents’daily life. Compared to other travel activities, it is more invariable in trip time and space. With the expansion of urban scope and separation between residential and work areas, the commuting distance is increasing. The commuting corridor is a geographically linear transportation system serving for commuters traveling between residential subdivisions and urban central business districts (CBD). Generally, major commuting corridors in metropolitan areas comprise multiple transportation modes for commuters, such as transit (subways or buses), private vehicles, and park-and-ride (P&R) combinations.This thesis studies the basic theories of P&R system and travel mode choice, develops a mode choice model for major commuting corridors, conducts a field survey to analyze the influence factors of mode choice behaviors, and evaluates the current state of P&R facilities’utilization in Beijing.In this study, a concept of transportation serviceability is introduced to evaluate a transportation service status for a certain mode in a specific link, route, road, or network during a certain period. The serviceability can be measured by the possibility that travelers choose a specific type of transportation service at a certain travel cost. The commuters’modal-choice possibilities are calculated using a stochastic equilibrium model based on general travel cost. The modeling results illustrate how transportation serviceability is influenced by non-commuting background traffic flow in a corridor, value of comfort for railway mode, and parking fee distribution.Based on the data analysis of field survey, some key parameters are provided and advice for P&R’s design improvement is proposed. |
