A Coordinated Adaptive Traffic Control Strategy Based on Phase-Time Network

Successful traffic signal system implementation will maximize available resources for effective coordinated operations during under saturated conditions, demand variations, and near-saturation conditions. These strategies will allow signal systems to react quickly to anticipated volume surges, to manage queues better, and to recover quickly from congestion by implementing coordination settings such as using early return, late arrival, and platoon identification schemes. These operational guidelines could also be used to take advantage of many currently available traffic monitoring and signal system fine-tuning capabilities to postpone the possibility of oversaturation on many highways and major arterials. Earlier, coordination has been used in actuated traffic control systems and fixed timed traffic-controlled system. However, in this paper we are going to do time-based coordination in an adaptive traffic control system using in the phase time network. This indicates the uniqueness of this work where we used an adaptive controller in a coordinated intersection to analyze the performance of an isolated intersection using the phase time network model.
