This study is focused on the concept of vehicle-to-infrastructure (V2X) cooperation via the Intelligent Transportation Systems (ITS) initiative; something which could provide comprehensive real-time information on the movements of vehicles throughout the entire road network, lead to a transformational change in how traffic is controlled, and address the significant problem of congestion along arterial routes. Until recently, 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. However, the widespread availability of traffic probe data can now provide real-time measures of effectiveness that allow objective signal control and measurable improvements in the efficiency of the traffic network.
