Optimization design and simulation evaluation of traffic organization at level intersection

As a component of traffic system, the level intersection is the node most likely to cause traffic congestion and traffic accidents. Based on the causes of congestion and the current traffic organization survey of the level intersection of Fushou Road and Xinxing Road in Liaoyuan City, were the road canalization and the optimization of signal timing phase for the intersection of Fushou Road and Xinxing Road were conducted. Indicators such as capacity, saturation, service level, queue length and vehicle delay were used for evaluation and analysis, and VISSIM simulation was used to verify the scheme. The results show that the intersection capacity of the optimized scheme was improved by 43.78%. The saturation level decreased by 45.04%. The level of service was improved to level 2. Vehicle delays decreased by 33.01%. The maximum queue length decreased by 33.63%. The traffic condition at the intersection of Fushou Road and Xinxing Road in Liaoyuan City was improved, which can demonstrate the effectiveness of the scheme.
