英文摘要：

For traffic evaluation system,the computer simulation method has many advantages such as being less time-consuming and less expensive,safer and more feasible.With the development of parallel computing technologies,fast simulation in large-scale road network can be done.We first analyze the feasibility of parallel simulation for microscopic traffic network and then provide a generalization and comparison of the two algorithms AIMSUN and TRANSIMS.We develop a suitable method and strategy for the parallel simulation of microscopic traffic network.The tests on a large scale traffic network show that the method is efficient and scalable.
