Developing Analysis, Modeling, and Simulation Tools for Connected Automated Vehicle Applications: Traffic Optimization for Signalized Corridors–Case Studies in Ann Arbor, MI, and Conroe, TX

Traffic Optimization for Signalized Corridors (TOSCo) is an innovative connected and automated vehicle application that has the potential to generate substantial mobility and air quality benefits for public agencies and potential fuel savings benefits for the traveling public. Under the TOSCo system, vehicles equipped with TOSCo functionality use signal phase and timing and queue information from the infrastructure to plan speed trajectories that allow them to reduce the likelihood of stopping at TOSCo-supported intersections. The TOSCo system also includes a coordinated launch feature that allows a string of TOSCo-equipped vehicles to leave an intersection simultaneously, in a coordinated fashion, to reduce the startup loss time, which, in turn, increases the capacity of the intersection. This report presented the methodology and results of traffic simulation activities supporting the development of the TOSCo system, especially the infrastructure-based algorithms. This report used a developed traffic simulation to evaluate the effectiveness and potential mobility and environmental benefits that could be generated through the application of the TOSCo system in both low- and high-speed corridor environments.
