Abstract:

Variable message signs (VMS) can be used to divert traffic to less congested areas of road networks and enhance network performance. Central to these goals are ensuring the increased acceptability of the suggested guidance and improving the credibility of VMS information among drivers. This paper aims to develop a behavior-consistent anticipatory en-route guidance methodology to determine VMS-based route guidance strategies that are consistent with the controller’s objectives and drivers’ en-route diversion behavior. The optimization procedure of route guidance strategies comprises a VMS control heuristic model that determines the desired diversion rates to satisfy some system-wide objectives of the controller, a VMS-based route guidance model that updates the VMS message strategies to minimize the difference between the desired diversion rates and the diversion rates obtained from the diversion behavior model, and a controller-estimated drivers’ en-route diversion behavior model that predicts the likely driver route choice decisions in light of the updated VMS message strategies. The implementation results demonstrate that the VMS-based guidance information displayed by the proposed model is well received by drivers. The findings also reveal that the integrated and coordinated VMS-based route guidance strategies effectively provides guidance to drivers, enhances the accuracy of traffic state prediction, and encourages better use of roadway capacity, thereby resulting in better system performance over the same period of operations.
