Abstract
Scientific optimization design of isolated intersection, which as the key point of city arterial road, is of great significance to improve traffic capability. The core intersection on the arterial road in Shenyang was selected as research object. Based on traffic parameter investigation and delay evaluation of intersection status, bus station settings, traffic organization and signal control were optimized and the optimization effect was simulated. The results show that intersection saturation and queue length decrease, while traffic flow average speed increase, further, vehicle average delay is reduced from 60 to 25 s, while intersection level of service is raised from E to C. The optimization effect is obvious and perfect. It suggests that the optimization design of intersection can actually not only reduce the traffic delay, improve the level of service, but also ensure city arterial road being safe and smooth.
