Methodology of developing a tour mode choice model of workers in western province, Sri Lanka

Abstract

This study is based on work tours which can identify by considering all the trips as a chain starting and ending at home. Tour mode estimation is one step in the Activity-Based Model needed to be followed once tour patterns are identified. The socio-economics/demographic characteristics of individuals and households, level of service attributes, tour/trip details, and land-use attributes influence tour mode. A choice model needs to estimate the tour mode using these influential factors. Assigning a tour mode for each tour is required before model formulation. The main objective of this paper is to propose a method to estimate tour modes for individuals in Western Province, Sri Lanka. The required travel details were collected from the CoMTrans 2013/14 Household Visit Survey data. This paper includes only the work tours and describes the methodology to estimate the tour mode choice model. The authors introduce a process to identify the tour modes out of trip modes. The descriptive analysis of tour mode with the tour pattern details is included. The estimated results in tour mode for the Colombo district were presented. The mathematical techniques, details of data needed, and required software for estimating the tour mode choice model are mentioned in this paper.
