MODELING EN-ROUTE DIVERSION BEHAVIOR UNDER ON-SITE TRAFFIC INFORMATION

Abstract

Real-time traffic information is considered as system which can alleviate traffic congestion. Effective information will help drivers make efficient travel decisions, and improve network performance. To make efficient strategy of providing information, the analyzer should quantify the reduced congestion by the traffic information. Many other route diversion models considered only media-information as information sources and ignored the influence of on-site information such as visible delay or average speed, which in practice affects drivers' route diversion decision. In those models, the influence of on-site information could be disguised to the influence of media information, and the effectiveness of media information would be over-estimated. The proposed model including the influence of on-site information will contribute to estimate accurately the influence of information on drivers' route diversion decision and network performance.
