The simulation of traffic flow at signal intersection by using object-oriented database models

The paper builds up traffic flow simulated models at signal intersection and describes analysis, design and implementation of software system by applying software engineering theory. The paper makes use of the object-oriented technology which imitates man´s thinking to model the rule of vehicle arriving intersection, the rule of lane choice, the rule of vehicle leaving from intersection. The simulation of traffic flow at signal intersection is an up-to-date method to research traffic control. It is expected that this paper contributes to the understanding of how to describe the complicated traffic phenomenon with computer language.
