Title: Delay Analysison Inside Left-turning Flow Based on VISSIM Simulation
Abstract: Taking the intersection with two separate left-turning lanes as an example,this paper analyzes the delay of inside left-turning flow which is always affected by lateral left-turning flow through VISSIM simulation system.In the process of simulation,the traffic flow parameters of the inside left-turning lane are set as constants while the corresponding parameters of the lateral left-turning lane are to be variables,and then the discrete data is obtained.The linear regression is conducted and the influence factor model is obtained for the inside left-turning delay.Furthermore,the paper proposes some improvement measures based on the simulation results.From the comparisons of the delay of inside left-turning and the intersection at each cycle that before and after the improvement,is the measures are proven to be effective.It also provides references for other similar intersections.
