Application of distributed and parallel computing in traffic network simulation
|
Abstract:
The paper designed framework of parallel traffic simulation system using domain decomposition method according to parallel characteristics of traffic network simulation, which meant that traffic network was partitioned to several sub-network, and each processor of clusters was responsible for a different sub-network of the simulated region. Used a network-partition al- gorithm based on the number of vehicle to optimize load balancing. Described information exchange mechanism between subnetworks, the developed parallel simulation system in parallel computing platform based on message passing interface. From the results of numerical example, the proposed parallel simulation algorithm can improve speed and efficiency of traffic network simulation.
