Using simulation case studies to evaluate connected vehicle applications.

Summary Information

This research evaluated the benefits of cooperative vehicle intersection control (CVIC) systems. A microscopic simulation model (VISSIM) was constructed to represent a hypothetical arterial consisting of four single-lane intersections spaced 400 meters apart. At each intersection an Intersection Control Agent (ICA) and an advanced algorithm were used to collect and analyze V2I data and recommend vehicle control actions to optimize network performance. The simulation included eight congestion scenarios ranging from low to high traffic volume conditions. Each scenario was analyzed to estimate network performance with and without the CVIC on a baseline network of coordinated actuated control at each intersection.

The authors discussed several important assumptions in the analysis including a market penetration rate that was set at 100 percent and the technical performance of wireless communications for connected vehicles which was assumed perfect.


Delay was defined as standstill time resulting from congestion at intersections.
  • Compared to actuated control systems the CVIC system reduced total delay times between 82 and 100 percent depending on the traffic volume levels simulated.
