Model Predictive Control for Three-Intersection Traffic Control Including Bus-Only Lanes

In this paper, we propose a model predictive control (MPC) method based on an enhanced urban traffic model. The aim is to enhance intersection access efficiency and alleviate congestion. The model incorporates two main improvements: 1) the separate modeling of ordinary vehicles and buses on urban roads, taking into account dedicated lanes and stops for buses, and 2) the inclusion of three intersections in the traffic network to capture the interactive influence of two road sections. Building upon this improved model, we design an MPC controller to regulate the traffic light status at the intersections and effectively control traffic flow. We provide simulation results of the controller implemented in the traffic network and compare with other scheme to validate the effectiveness of the model and control strategy.
