Improving the Operations of Managed Lanes through Vehicle Infrastructure Cooperation

This paper introduces innovative mobility services and explains how these services could operate and might improve the performance of managed lanes on freeways. The mobility services outlined include real-time freeway management, speed adaptation services, car following services, condition warning services, and merge integration services. These basic mobility services can be deployed through the fundamental vehicle-infrastructure cooperation (VIC) communications architecture that has been proposed for the Vehicle- Infrastructure Integration (VII) partnership, complemented by additional in-vehicle service applications. The author discusses the potential value of these applications in the context of real-world situations that compare the potential performance of a freeway with a designated HOV/HOT lane with and without the inclusion of vehicles with VIC-enabled car following services. The author concludes that these innovative mobility services can have significant benefits to traffic throughput and level of service, and will also result in improved safety performance.
