Drivers’ Route Choice Behavior Analysis Based on Cumulative Prospect Theory

Due to different travel experiences, travel attitude varies from people of different levels of familiarity with urban route network. Expected utility theory (EUT) is usually used to describe travelers’ route choice behavior. But there is huge discrepancy between reality and the results under the condition with network uncertainty when the cumulative prospect theory (CPT) is more attractive to describe the travelers’ route choice behavior. Based on CPT this study designs scenarios at different levels of familiarity with urban road network, analyzes route choice behavior in all scenarios and conclude travelers’ behavior characteristics compared with reality investigation results. It shows that CPT is really more powerful to describe the travelers’ behavior under risk and people of high familiarity level are more relied on constraint time and tend to take a risk for more gain.
