Abstract: The various problems in urban roadway traffic are discussed. The progress in the traffic flow models based on fluid dynamics, gas kinetics, car following and cellular automaton is summarized from the point of view of continuous, probability and discrete methods. The features of these models are described. At last, the further prospective research on traffic flow is cxamined.

Key words: urban roadway traffic, traffic flow models, computer simulation
