The concept of circular coloring is introduced and the number of optimized phase of traffic flow signal at an intersection in a city is boiled down to the circular chromatic number of the traffic flow model graphs.The traffic conditions on a few classes of special crossroads are analyzed and,from the confliction relations of traffic flow we can get the traffic flow model graphs and their circular chromatic numbers,namely,the optimization phase number of corresponding traffic signal.
