Abstract:
Traffic is one of the biggest problems of modern societies that followed by numerous problems such as wasting time, increased fuel consumption and environmental pollution, vehicle depreciation, reduce safety and increase accidents and casualties of the financial. Thus, increasing the efficiency of network traffic, reducing congestion and improving safety, considered one of the important objectives around the world. Network traffic intersections are an important part of urban streets that they are the core of congestion and contributing factors to the traffic flow. Traffic management in traffic-light-less intersections is a major challenge because the passage of vehicles regardless of the priority of traffic rules, may lead to accidents or deadlock at the intersection and make traffic or increase the average waiting time of vehicles due to traffic jam. Therefore, in this study proposed a mechanism that receive primary context information of vehicles and concludes effective secondary context information in decision making, then the priority of vehicles is calculated. Proposed mechanism uses a formula to calculate the priority vehicles that is obtained using the concepts of multi criteria decision making with regard to the effectiveness of any of the information effective in reducing the average latency of intersection. Processing operation is carried out to investigate the confirmation/ rejection of crossing the intersection on their priorities. This mechanism is designed so that traffic management prevents the creation of deadlock, hungry and traffic nodes and significantly reduce the average waiting time of vehicles. The results of simulation of proposed mechanism compared with five traffic management system that shows at intersections with different arrival rate, the proposed mechanism reduces the average delay to each of these five mechanisms.
