Development of a connection method of large-scale microscopic road traffic from parallel processing

Abstract

In recent years, a high-speed acceleration simulation with a road traffic simulator is needed because of a large-scale traffic jam calculation etc. To satisfy the demand of this society, we improve microscopic road traffic simulator MITRAM, and have developed parallel MITRAM that can simulate a larger-scale region. However, an existing parallel system hardly corresponded to a complex road connection, and it was difficult to simulate it in a complex urban area. In the present study, it aims developing a new connection method for this parallel MITRAM, and doing with parallel MITRAM even what complex and vast urban area simulation it is. Moreover, the performance comparative simulation is done in parallel MITRAM and usually, and how the improvement of the acceleration performance and the load reduction is verified.
