The distribution of traffic lights has close relation with the delaying vehicles at the intersection, and the question whether we can dispatch the traffic lights effectively and reasonably or not is the key to solve traffic congestion and jams.So this paper is intend to put forward a real-time dynamic distrbution model of traffic lights.Taking the Jiedaokou of Wuhan city as an example,we find that the model has really a useful value in solving the traffic congestion when compared with the traditional fixed dispatch models. 周期 相位 绿信比 cycle phase green ratio O231 国家自然科学基金资助项目 （ 7992 80 0 1,79870 0 91,A0 2 2 40 17） 2003-03-01 2021-04-01 3
