Intersections,especially the complex and irregular ones,are often the most disorderly,traffic congested,and accident prone points in the urban road network with the lowest traffic efficiency,frequent traffic congestion,and the highest accident rate.Studying traffic control measures is the key to improve the overall efficiency of the road network.It also needs to be optimized and adjusted dynamically with the improvements of road networks and changes of traffic flow characteristics.Taking the complex intersection of Hongqiao Road,Yan'an Road and Gubei Road as an example,this paper further studies the improvement measures on the basis of a lot of optimizations already done in the present situation.The improvement schemes are proposed from the aspects of network diversion,traffic organization and node design.Traffic simulation technology is used to verify the effectiveness of improvement measures.
