Traffic network simulation describes movement behaviors and track of individual *** network is scale-up, the process takes more time and computing resources. Moreover,computing capacity of single processor computer cannot satisfy simulation requirement.A distributed and parallel computing approach to such a large-scale traffic system might be economical and *** paper designs framework of parallel traffic simulation system by using dornain decomposition method according to parallel characteristics of traffic network simulation,in other words, traffic network is partitioned to several sub-networks,and each processor of clusters is responsible for a different sub-network of the simulated region.A network-partition algorithm based on the number of vehicle is used to optimize load *** exchange mechanism between sub-networks is *** developed parallel simulation system is implemented in parallel computing platform based on Message Passing *** the results of numerical example,the proposed parallel simulation algorithm can improve speed and efficiency of traffic network *** algorithm provides a foundation for larger scale traffic network simulation and real-time applications.
