Abstract
Mode choice model explicitly considering travel time reliability is developed. This model quantifies travelers' attitudes towards travel time fluctuation as well as average travel time. Discrete choice model is estimated using survey data of new town commuters' decision making, which is drastically changed after major transportation closure.
First, this paper discusses the background of the research. Second, the significance of reliability of transportation systems is presented in chapter 2 where a state-of-the-art is briefly shown. Chapter 3 describes the case study area and the incident which caused the major transportation service halt. In chapter 4 and 5, mode choice model for assessing travel time reliability is proposed, after several models are tested using the actual data for normal period. Finally, change in mode choice behavior before and after the temporal closure of major transportation service is presented. The commuters' attitude towards travel time reliability is discussed for normal and abnormal periods.
