Reducing Traffic Congestion in Modern Cities, A Challenge Based on Physico-Mathematical Theories and Wireless Sensor Network

During the last decade, the ever increasing number of vehicles has worsened the traffic congestion which has become a hot topic in large urban areas. The solution to reduce this congestion in modern cities is based on the optimization of light signals through communication between the wireless sensor placed on each lane and the traffic light controller. It leads to phase duration changes implied by traffic demand. To be more exhaustive, the traffic control at a crossroads aims at therefore determining the sequences of vehicles crossing i.e. the distribution sequences to enjoy the right of crossing (green traffic light). This new strategy of traffic control has plenty potentialities to exploit the abilities of the intersection. Through this article we will take into account the parameters to diminish the effects of the congestion traffic, as we get on a physico-mathematical model so as to increase the flow of road traffic and avoid road traffic and congestion.
