Optimized traffic flow at a single intersection: traffic responsive signalization

Abstract

We propose a stochastic model for the intersection of two urban streets. The\nvehicular traffic at the intersection is controlled by a set of traffic lights\nwhich can be operated subject to fix-time as well as traffic adaptive schemes.\nVehicular dynamics is simulated within the framework of the probabilistic\ncellular automata and the delay experienced by the traffic at each individual\nstreet is evaluated for specified time intervals. Minimising the total delay of\nboth streets gives rise to the optimum signalisation of traffic lights. We\npropose some traffic responsive signalisation algorithms which are based on the\nconcept of cut-off queue length and cut-off density.\n
