An Eco-Traffic Signal System Based on Connected Vehicle Technology Thesis uri icon



  • Thesis (M.S., Computer Science) -- University of Idaho, 2016 | The Intelligent Transportation System uses Dedicated Short Range Communications (DSRC) for vehicle-to-vehicle and vehicle-to-infrastructure communication. This technology is used for applications that intend to increase safety and to improve traffic management and operation. For the latter it promises applications with advanced features in order to reduce fuel consumption. This research presents the design and implementation of a system architecture, diverse algorithms, and communication methods of an Eco-Traffic Signal System. The application uses vehicle-to-infrastructure communications to control traffic light timing with the goal of avoiding unnecessary stops of heavy vehicles, which in turn results in energy savings. The architecture takes advantage of Basic Safety Messages in connected vehicle technology and executes an application inside of the Road Side Unit employed in future traffic intersections. This unit facilitates the necessary algorithms and communication support to instruct the traffic controller to manage signal timing. A proof of concept of the Eco-Traffic Signal System was implemented and its functionality was verified in field tests using commercial DSRC equipment.
