Abstract
Through researching the traffic flow regularity of single intersection, this paper puts forward an intelligent traffic light (design) method based on BP neutral network principle and fuzzy control theory, in which the variable parameter is the dynamic change of traffic flow. The traffic light control system based on the neutral network fuzzy control technology breaks through the traditional mechanical timing pattern and general control mode. According to the real-time traffic flow, this technology can operate flexibly, and it has “Associative Memory” function when it realizes the fuzzy inference by neutral network .Thus it can meet the emergency of single transformation under any circumstance and then reach the optimum delay time of green light. The simulation result by MATLAB shows that the neutral network fuzzy control technology is superior to general fuzzy control method, which greatly improves the traffic utilization and brings the obvious economic benefit.
