In order to alleviate the problems of vehicle delay and low traffic efficiency at large intersections,the paper takes the intersection of Nanneihuan Street and Jianshe South Road in Taiyuan City as the research object,through on-the-spot understanding of the traffic situation of the intersection,the paper puts forward the short-term and long-term optimization design schemes of the intersection from the plane channelization design,slow traffic design and signal timing design,and simulates different schemes with VISSIM software.The analytic hierarchy process(AHP)is used to comprehensively evalua...
