Mode Choice Model for Intercity Travel - A Case Study

Abstract

Intercity transportation planning is a vital link in the overall transportation planning process which directly affect between the urban transportation and regional transportation planning. The traditional method of estimating the travel demand function is to decompose it into a number of travel attributes associated with each of the descriptors of travel (origin, destination, mode and route etc.). Out of these "modal split" stage is very important as considerable amount of work has been done on trip generation and distribution and not much on this stage. The modal split stage involves establishing the modal share for the existing travel pattern, determining the response to causative factors and finally projecting the modal share for the future. There are number of routes along which both rail and road facilities are available. Without proper analysis and control of various variables responsible for modal split, there is every possibility of bus and train modes becoming competitive when they actually must be complementary. In this study it is proposed to do the mode split analysis using DOGIT model calibrated with the help of WLGIT Computer package. Eluru-Vizag corridor in Andhra Pradesh is selected to test the validity of the computer package WLOGIT.
