Modelling Modal Shift from Personal Vehicles to Bus on Introduction of Bus Priority Measure

Abstract

This study is concerned with estimation of the probable shift of the personal vehicle users to bus due to increase in its level of service, due to provision ofexclusive bus lanes, on Indian city roads. The quantum of increase in level of service of bus, due to introduction of exclusive bus lane, was determined using a recently developed simulation model of heterogeneous traffic flow. The data of the other factors (variables) that might cause modal shift from personal vehicles to bus were collected through home-interview survey based on stated preference approach. Modechoice models to explain the shift behaviour of the users of motorised two-wheeler, auto-rickshaw and car to bus are developed. Modal shift probability curves are also developed, to serve as user friendly tool to analyze the probable modal shift for a wide range of the involved variables.
