Abstract:

The accurate identification of intersection traffic state is the premise and basis for the implementation of corresponding control strategy. According to the problem of traffic state identification, the intersection traffic state distinction method that based on comprehensive projection is proposed. At first, by studying the inner link between each stage flow and split of intersection, traffic and split diagram is established. And from the perspective of the two stage control of intersection focus on the analysis of intersection traffic state, through time- line diagram to determine each phase under different traffic states intersection line up, so as to match the traffic state. The second, on the basis of the two phase control intersections, through the projection and the projection comprehensive projection method is put forward, and a traffic state distinction method that suit multi- stage control is established. At last, the distinction of the actual intersection verified the feasibility and effectiveness of this method.
