Method of traffic light intelligent control based on FPGA and MRFO algorithm
摘要
Abstract
In order to carry out adaptive traffic light adjustment according to traffic flow conditions,maximize traffic efficiency,and improve the level of intelligent traffic management,a method of traffic light intelligent control based on FPGA and MRFO algorithm is proposed.The traffic light intelligent control framework based on field-programmable gate array(FPGA)is constructed by analyzing the actual demand of traffic light intelligent control.Based on the intelligent control framework,the minimum objective function and related constraint conditions of the delay time of all traffic flow direction vehicles at the traffic intersection are constructed according to the actual traffic operation.The Manta ray foraging optimization(MRFO)algorithm is used to iteratively optimize the objective function of intelligent control of traffic lights under the condition of satisfying constraints,and the optimal control strategy is obtained to realize intelligent control of traffic lights.After experimental verification,this method can realize low delay level with less training samples and highly efficient.It can also adaptively adjust the signal light duration based on the traffic flow at intersections,ensuring the vehicle passing rate of over 96%.It effectively proves that the method can alleviate road congestion,reduce the occurrence of safety accidents,and thereby enhance traffic safety level.Its effectiveness is verified.关键词
