Abstract: In order to explore the traffic diversion adjacent to the highway work zone, this paper investigates the effect of the short-term and long-term work zone with the simulation method. Additionally, a predicting model for the traffic diversion was built based on the demand/capacity ratio and number of days. The results indicate the dynamic traffic assignment and day-to-day learning module are able to simulate effects of travel time variance on travelling route choice. Moreover, the time variable is not significant for the diversion in short-term work zone, while the long-term work zone is mainly affected by the demand/capacity ratio. The simulation approach and traffic diversion predicting model is meaningful for the traffic management in highway work zone.

Key words: highway work zone, traffic diversion, dynamic traffic assignment, predicting model for diversion
