Abstract

This study examines the existing pattern of access trips to rail transit in Bombay, India, through the collection of revealed and stated information from randomly selected households, develops a policy-sensitive access mode choice model, and defines accessibility to transit with inputs from socio-environment aspects. A maximum information procedure is developed to identify the shift potential due to the provision of better access conditions. A model is developed using joint estimation approach for the prediction of mode shares under policy effects. The environmental transit accessibility index, defined in this study, considers the effect of socioeconomic characteristics of commuters, the economic and environmental implications and the behavior of commuters under the hypothetical scenarios. The index is defined both for base year and for scenario year. A scale for evaluating environment transit accessibility is proposed. The approach developed here seems to define transit accessibility satisfactorily for the study area, and can be extended for examining the effect of policy on all types of transit facilities.
