Synergistic Optimization Model of Length and Signal Timing Parameters of Left-Turn Short Lane

The optimal configuration of time and space resources was discussed in allusion to the signalized intersections where the left-turn short lane had been channeled.According to analyzing the impact of short lane on saturation flow rate of approach,a combined signal timing optimization model was established and solved by applying MATLAB and using traffic survey data from Dalian City.Then the simulated experiments were designed by VISSIM.The results show that the synergistic design of traffic organization and signal control can optimally configure time and space resources of intersection so that the performance of intersection can be fully exerted.
