The Variable Speed Limit (VSL) application provides travelers with dynamic speed advisory information to keep optimal traffic flow conditions for freeways and corridors under both recurrent and non-recurrent congestion incurred by incidents and/or work-zones. By coupling VSL and Connected Vehicle (CV) environment enabling two-way wireless communications for vehicle-to-vehicle and vehicle-to-infrastructure, it is expected to achieve improved performance of VSL as a viable traffic congestion mitigation tool. This digest paper presents the impact of connected vehicle on the effectiveness of VSL on a freeway bottleneck section by using a microscopic simulation model. Simulation experimental results show that CV-powered VSL improves the traffic congestion conditions up to 7–12% depending on CV market penetration rates.
