Research on traffic light setting based on single objective nonlinear programming

We establish a time-scheduling optimization model of single-objective nonlinear programming with the goal of minimizing parking length, and obtain the green flashing time which should be arranged and allocated theoretically. At the same time, field research and data recording are carried out in combination with the T-shaped traffic lights and intersections in Nanchong city. By studying the indefinite period timing strategy, a mathematical model is established from the perspective of mapping, and all the combinations of driving routes (the one-to-one combination of the main road and the compatible routes that can pass at the same time) are analyzed, the theoretical allocation time of cycle is solved and predicted, and the rationality of the model is verified according to the vehicle passing rate before and after optimization.
