The Timing Optimization of One-Way Traffic Signal Intersection Based on Vissim Simulation

The signal timing plan plays a pivotal role in influencing the efficiency of one-way traffic operations. In this study, we focused on optimizing the performance of a one-way traffic intersection in Xi’an to alleviate urban traffic challenges. Firstly, we introduced a signal timing optimization scheme. Afterwards, we utilized Vissim simulation software to model and compare intersection performance before and after the optimization process. Three key evaluation metrics—travel time, queue length, and delay—were employed to assess the impact of the optimization. The results demonstrate that Vissim simulation proves an effective tool for optimizing one-way traffic signal timing, providing a clear basis for comparing outcomes before and after the optimization.
