Impact of the Signal Timing Optimization on Traffic Environment of Urban Road Based on TSIS

At present, traffic jams and the atmospheric environment have become worse and worse in Jinan City. In this paper, the authors adopt traffic simulation method and try to find out an effective solution for these problems by optimizing the signal timing schemes. The road section near the east gate of Baotu Spring was taken as an example, and a series of field measurements were conducted on this section to obtain some parameters as the input for TSIS software. The parameters, such as average traveling speed, the vehicle emissions, the average fuel consumption and the traffic delay, were taken as the optimal objects. Some reasonable timing schemes were recommended for signal controlling. On the basis of TSIS, the authors quantitatively analyze the improvement of the above parameters. The optimal scheme can increase the average speed of vehicles in the road section by 24%, decrease the average control delay by 25%, reduce the overall fuel consumption by 17%, and CO emission by 7%, and the simulation result is then validated.
