Benefit Summary HTML

Utah DOT developed a project based on the initial 2016 deployment of a full Dedicated Short-Range Communications (DSRC) corridor that supported transit signal priority (TSP) controls to leverage connected and automated vehicle (CAV) technology. The deployment site is located along Redmond Road, an 11-mile urban corridor with 30 signalized intersections located in Salt Lake City. Onboard communication devices were installed on transit vehicles to support the TSP system.

The project aimed to collect bus data along the DSRC corridor to evaluate the efficiency of the technology's investment and perform a benefit-cost (B/C) analysis. Moreover, this project integrated adaptive traffic  and signal coordination controls into the existing system to optimize signal timing at the intersection level and offset at the corridor level. A microscopic simulation environment based on the DSRC corridor was developed to evaluate the potential effects of the proposed signal control system.
