This paper defines transit access incorporating the system attributes, viz, availability of access modes, their availability distance from residence, the difference in detour and airline distance to transit station and the condition of fixed facilities and flow entities, the shift potential under the effect of policies and the economic implications of pollution loading. The analysis is based on revealed and stated preference data. 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 the commuter, the economic and environmental implications and the behaviour of commuter 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 is found defining transit accessibility satisfactorily for the study area. (Author/publisher).
