The problem of traffic regulation has been a big problem in many countries for many years. One of the most acceptable methods of decoupling the traffic flow is to optimize the operation of the traffic light. This article presents a simulation method used to find the optimal modes of operation of a traffic light at a given intersection. Models were created that simulate the transport networks of the city, on the basis of which the experimental results of this simulation were obtained. The simulation was carried out on the basis of optimizing the time of the traffic light on the given sections of the routes. To optimize the operation of traffic lights, the following sequence of operations was implemented: during the iteration, optimization parameters were selected from those specified in the database, followed by work on the model based on these parameters; at the end of one cycle of the model, the value of the optimizing function was determined at the time of the cycle completion. The resulting optimizing function is analyzed and, if necessary, new values of the optimization parameters are introduced, a new value of the optimization function is found, and the process is repeated until the function satisfies the specified initial conditions or reaches a constant value. The data obtained as a result of the optimization showed that the optimization made it possible to increase the capacity of busy intersections by almost three times. |
