Abstract :
Increasing efforts are devoted to test and improve the performance of commercial traffic simulation software now. However, most previous approaches emphasized microscopic car-following and lane-changing features but neglect the macroscopic traffic dynamics. In this paper, we compare the traffic flow phase transition behaviors of three popular simulation software: PARAMICS 6.5, TransModeler 2.0 and VISSIM 5.1 on a single yet typical scenario. Our testing re-sults show that their slight differences in microscopic models can be appropriately magnified and intuitively displayed in the phase diagram.
