|Project Description:||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.|
|Start Date:||February 16, 2010|
|End Date:||August 30, 2013|
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.
|Test Methodology:||Work performed under this project presents an opportunity to overcome this impediment and to fundamentally rethink traffic signal operations based on the impending widespread availability of traffic probe data. Vehicle-infrastructure cooperation via the connected vehicle initiative could provide this comprehensive real-time information on the movements of vehicles throughout the entire road network, and allow a transformational change in how we control traffic and, finally, significantly address the problem of congestion along arterials.|
|Expected Benefits:||Work performed under this project presents an opportunity to overcome this impediment and to fundamentally rethink traffic signal operations based on the impending widespread availability of traffic probe data.|
