Advanced Traffic Signal Control Algorithms
Highway congestion is largely caused by the inefficiency with which the roadway network capacity is managed. Traffic signals are the mechanism for managing arterial network capacity, yet the control of traffic signals has not significantly changed over the past several decades, despite rapid and profound changes in electronics, sensors and communication technologies, and software. The main impediment to improvements in traffic signal systems has been the limited ability of available fixed-point detectors to measure the true state of the traffic network and its response to signal changes.
The goal of this project is to develop advanced signal control strategies based on connected vehicle data, i.e., real-time information on a vehicle's location, speed, and characteristics, as well as communication to the signal control infrastructure.
