Arterial Coordination Optimization Based on Trajectory Data

With the rapid development of urban traffic, the problem of urban traffic congestion is becoming more and more serious. Solving the traffic congestion of the main arterials of urban area is of great significance to alleviate the urban traffic congestion. Arterial coordination optimization is an effective method to improve arterial capacity, service level, and alleviate the urban traffic congestion. In this paper, an arterial coordination optimization model has been proposed with the analysis and processing of the vehicle trajectory. First, the characteristic trajectories are extracted according to the velocity distribution of the arterial line. Then, the intersection delay model is established to optimize the characteristic trajectories to obtain the phase difference for each intersection. The simulation result by SUMO software shows our method has 45.48% improvement in parking delay and 14.08% improvement in the average queue length at each intersection, which proves effectiveness of the proposed method.
