    This paper, on the base of basic dynamic model and through the modification of the speed equation presents an extended dynamic model of freeway traffic to describe a complex traffic flow such as that on inner urban freeways and improve the accuracy of traffic analysis and control system design. The author has accomplished modeling and simulating for a real freeway.
