The communication between roadside units (RSUs) and onboard units (OBUs) using dedicated short range communication (DSRC) was implemented across 22 intersections on Mahan corridor in the City of Tallahassee with the aim of broadcasting signal phasing and timing (SPaT) and intersection map (MAP) information to OBU-equipped vehicles. The overall goal of this project was to evaluate the efficacy of SPaT/MAP broadcasting in improving efficiency and safety of road users along a signalized corridor. There were four main tasks that were undertaken: (1) pre-ATSPM/CV operational and safety studies; (2) overall performance evaluation of SPaT/MAP broadcasting and the other underlying potential applications brought about by the DSRC implementation on the Mahan corridor; (3) evaluation of driver behavior and attitudes towards SPaT/MAP deployment; and (4) qualitative review of C-V2X communication systems in relation to enabling infrastructure owners and operators (IOO) to broadcast roadway, traffic, weather, and signalization information. The report is divided into four chapters detailing the tasks undertaken, the results obtained, and the conclusions and recommendations made.
