Traffic organization optimization at complex intersection of mountain cities

Complex intersection is the bottle-neck of urban traffic.Reasonable traffic organization is an important way to improve the capacity of complex intersection.Based on the geometric features,traffic operation and management,a method of traffic organization optimization at complex intersection is proposed.A case study in Chongqing is shown,in which the software,SIDRAINTERSECTION,is used to analyze the traffic organization optimization schemes.The results show that this method can combine traffic channelization with traffic signal control to significantly improve the traffic movements and increase the efficiency.
