Computer simulation of traffic flows

Abstract

The paper is presented to the simulation of traffic flows in conditions of traffic light regulation. A simulation multi-agent model of traffic flows was developed, which includes three agents: a car, a traffic light, a generator. A computational algorithm for the movement of vehicles for imitating the movement of vehicles along the driving lanes and its behavior at the intersection was developed. The simulation multi-agent model and the computational algorithm are implemented in the form of an intelligent analytical system that includes a database designed in the MS SQL DBMS environment, as well as a visualization module. During the simulation of traffic flows in the system, the required output parameters of the model are fixed. By simulation tools one of the problematic road sections of the city of Izhevsk was built, including a network of intersections of 10 years of October Street, Udmurtskaya Street, Pushkinskaya Street. The developed simulation model allows calculating the indicators of the average queue length at different times of the day, taking into account the intensity of input traffic flows. Thus, graphs of the dynamics of changes in the average queue length can be obtained and, on their basis, the time periods of congestion occurrence are determined. For example, during the simulation of the operation of a section of the transport network of the city of Izhevsk, it was established that there are two time periods for the occurrence of traffic congestion: from 7:00-9:00 AM and 5:00-7:00 PM, in which the indicator of the maximum queue length reaches 40 cars.
