Accessibility index for comparison between private and collective transport modes

Abstract Aiming a qualitative and/or quantitative improvement of the offered transport services and its base infrastructure, it is observed the need to provide tools to evaluate accessibility, in order to diagnose the level of service to the users by the different modes of transport. This paper proposes to formulate an index allowing comparison of the accessibility of private and collective transport modes. The proposal is the result of extensive literature research, seeking to analyze characteristics, limitations and applicability of indices developed in previous studies. The proposal applicability was verified in a study developed in the city Palmas-TO. The index formulated gathers variables that allow its application to both private and collective modes, translating in terms of travel time different variables that characterize each mode. As a result of the analysis it is possible to evaluate in an integrated and spatialized way the accessibility to transport for different categories of users, besides allowing the simulation of interventions, aiding in the process of urban and transportation planning.
