摘要：
Concepts and attributes list of vehicle multi-agent(VMAs) in cooperative vehicles infrastructure system(CVIS) are introduced at first. Decision strategies in both traditional and CVIS circumstance are compared to analyze differences in traffic status judgment and decision at intersections and links between two circumstances. Single lane traffic flow models in CVIS are established. Microscopic traffic flow models such as acceleration and deceleration are given too. Furthermore, the intersection impacts are taken into consideration in analyzing the signal influence. The numeral experiments analyze the trajectories and macroscopic parameters in both circumstances. The results show that VMAs in CVIS decline sharply in total travel time, average travel time and average delay time which indicate that vehicles in CVIS are more stable and successive than those in traditional circumstance. Besides, headway and velocity variances in CVIS are lower than those in traditional circumstance which increases the fleet stable.
