| Abstract: | Based on the parallel processing techniques and object-oriented architecture, a framework for parallel and distributed traffic simulation is presented in this paper. Two modeling schemes are put forward: the first is an object-oriented and message-oriented parallel simulation approach for partitioned network. The other is a distributed discrete event simulation approach with standard clock for integra-ted network. The distributed traffic simulation approac h introduced in this paper will improve the computation efficiency gre atly and meet the needs of large-scale traffic network, high efficien cy and real-time operation of Intelligent Transportation Systems (ITS) . |
