Coordination strategy for vehicles passing multiple signalized intersections: A connected vehicle penetration rate study

In this paper, a hierarchical control architecture is applied to coordinate a group of connected vehicles passing through multiple interconnected signalized intersections. The traffic signal phase and timing (SPAT) information is assumed to be available for the intersection controller as well as the connected vehicles. With the SPAT information, our proposed approach is able to avoid or reduce the connected vehicle red light idling, thus improving the vehicle fuel economy and traffic mobility. The scenario with both connected and unconnected vehicles have also been considered in this paper. The simulation results show the effects on overall fuel economy caused by various connected vehicle penetration rates and the unconnected vehicle's position in the convoy.
