Traffic light synchronization

Abstract

Traffic Synchronization mechanisms aim at minimizing traffic bottle necks, controlling traffic flow, by means of dynamic adjustments in Traffic Signal timings. This paper presents a two level synchronization approach, Local Synchronization and Global Synchronization for synchronizing the traffic flow. Focusing upon determining the traffic light timings based not only upon the current lane densities perform the local synchronization which itself is standalone, and also the determination of the green time of the traffic signals based on the densities of the peer junctions at various levels, along with a set of parameters associated with these to provide Global Synchronization, easing out the traffic flow from the heavier density areas to the lower density zones. Hence, implementing two level intelligence platforms, the system serves as a reliable standalone traffic control system control even if either one of the intelligence platform goes down. © 2013 Springer-Verlag.
