Intelligent traffic signal control based on multiple agents

At present, with the rapid development of social economy, people's living standards have been gradually improved, and the number of urban motor vehicles has been increasing, resulting in increasingly prominent traffic problems, and traffic congestion has become an urgent problem to be solved. Wireless sensor network (WSN), as a new information acquisition and processing technology, has the characteristics of unrestricted environment, self-organization and distribution in traffic signal control system. However, due to the limitation of single sensor node itself, the multi-agent theory can be used as an effective method to describe and analyze. Based on this, this paper introduces the multi-agent technology to study the intelligent traffic signal control in the multi-agent environment, focusing on the single intersection signal control method and multi-intersection signal coordination control method.
