Effects of Dynamic Travel Information on Drivers' Heterogenous Adaptation Behavior to Traffic Accidents on Expressways

Focusing on the real-time traffic information, this study applies a stated preference (SP) survey and a data mining technique, called Exhaustive CHAID, to evaluate the effects of the information on drivers’ heterogeneous adaptation behavior to the occurrence of traffic accidents on expressways. Three decision scenes are targeted: before departure, on the way to expressway, and on expressway. SP survey is designed to reflect the influence of each respondent’s personal driving experience and preference for traffic information on the SP responses. Different from existing studies, several new types of traffic information are additionally examined. Taking the expressway of West NEXCO, Japan as an example, 10,000 SP responses were collected for each scene. Analyses identified about 30 adaptation patterns with considerably different influencing information contents. The importance of developing individualized traffic safety information systems is confirmed.
