Abstract

The article discusses tools for network modeling of information traffic and the integration of such tools with various models of road transport. The architecture of interaction of a discrete micro model, a macro model and a technology of road traffic control based on intelligent transport systems has been developed. OpenFOAM environment is used as macro model based on the modified Navier–Stokes equations. In this model the velocity– pressure relationship is resolved within the framework of the modified SIMPLE algorithm. The data obtained from the macro model is used to make decisions about possible routes of movement in the micro model, where the standard of wireless data transmission in mesh networks 802.11p is used to inform about the current and predicted traffic situation. The simulation parameters for the heterogeneous environment SUMO and OMNeT++ are presented. Built section of a real map, which is the part of the road network of St. Petersburg city. Several scenarios were used to generate traffic congestion during the experiments, where traffic flows were carried out without fixed routes. Experiments have been carried out showing a reduction in the time of movement of a stream of cars in a busy period of time using notification mechanisms and a macro model at given speed limits
