Abstract

Freeway traffic flow and safety are the main subjects of the current highway traffic operation in an intelligent transportation system. The traffic flow model and traffic safety evaluation model were studied in this paper to analysis the traffic operation under a new traffic rule of variable traffic flow density. The classic car-following model is used to describe the traffic flow under the intelligent traffic system, and the variable traffic flow density is derived according to the constraints of the left overtaking. The corresponding interval values of average speed discrete degree are obtained to score the traffic safety degree. Then cellular automata is used to simulate the model, finding that traffic flow remains unchanged, while the safety of the traffic increases.
