Improved signal timing optimization of plane intersections under ARRB model
Traffic capacity of road intersection is an important part of road service level,and the optimization of signal timing at intersection is an important means to improve traffic capacity and improve vehicle operation efficiency.Taking a road intersection as an example,field survey was conducted and corresponding data was collected.It was simulated using Vissim,and outputting parameters such as maximum queue length,parking delay and per capita delay.The operating condition of the road intersection was evaluated according to the relevant standards,the green light time of the road intersection was optimized through the ARRB signal cycle model,and Vissim was used to simulate and output relevant parameters,comparing with the parameters before optimization.The results showed that under the optimized signal timing scheme,the average maximum queuing length decreased by 29.83%,the average parking delay decreased by 40.17%,the average per capita delay decreased by 34.49%,and the traffic efficiency of the road intersection was significantly improved.
