Analysis on the Stated Preference of Route Choice Behavior under the Travel Time Information

Abstract

In recent years, we have been facing the decline of city functions by traffic jams during the peak hours of traffic in urban areas. It is necessary to conduct policies for the relaxation of traffic jams that cause big loss in social economic activities and road environment. It has been attached importance to policies of software side such as providing with information of route guidance or Transportation Demand Management (TDM). Demand of drivers have been diversified by the progress of information technology. As one the road traffic policies that make use of information technology, we can pick up the practical use of Intelligent Transport Systems (ITS). The provision of road traffic information for drivers is one of the ITS policies. The shortening of travel time is expected as one of the effects of information provision, and it is considered that we can drive cars more smoothly and comfortably. However, it is necessary to carry out detailed analysis on the reaction of drivers in order to develop the information provision service that can be accepted by car users.
We pay special attention to the travel time information system in this study and we take up route choice and change behavior as the reaction of driver to the virtual travel time information. In this study, we try to grasp the influence of provision of travel time information on the decision making of route choice behavior before the trip departure time.
