Supercomputer Technology for Traffic Simulation in a Metropolis

The present paper is aimed at the creation of a universal computational technology of multilane traffic and the development of robust tools for the simulation of vehicular traffic flows in megacities using parallel computing. The software is based on macro- as well as microscopic models. The macroscopic model uses the continuum approach and draws the analogy with the known quasigasdynamic system of equations. The multilane microscopic model is based on the cellular automata theory. Depending on the model different parallelization techniques are proposed to adapt city road networks to multiprocessor architectures. The models are implemented as program packages including the User Interface and Visualization module for transferring data to computational modules and providing visual interpretation of results. A number of test predictions have proven the effectiveness of the developed technology.
