摘要

In order to solve the problem existing in the single control mode of intelligent signal, a method for intelligent signal dynamic optimization based on grey system is proposed. Firstly . on the basis of the trend of traffic flow, the most similar sequence. one of the historical sequences in the same interval of various dates, is obtained by using grey relational analysis; Then, grey prediction model is established based on the change of trend of traffic flow and the most similar sequence, the dynamic prediction value is obtained; Futhermore, for the objective of the smallest delay time ,an optimization model is constructed in advance of the next signal cycle and split; Finally, traffic experiment on the section of Youyi Avenue is done in order to compare the signal system effection before and after optimization, the result shows that the inducted effects of optimized signal is improved significantly, which play the role of real-time controlling.
