The Researching And Implementation For Simulating Models Of Cooperative Vehicles Kinematic Behaviour Based On Discrete Time

With the development of social economy, security factors within vehicles kinematic behavior becomes more and more important. Considered the impediment of huge data information during the behavior and enormous expenses of experiment, the simulation of vehicles behavior is one of the best styles for researching works. Traditional simulation style is mostly researching under macroscopic level, shows the real traffic condition by using systematization traffic simulation. Since vehicles behavior is one kind of complicated and meticulous topic, it needs using a lot of knowledge about mathematics and physics. That is not easy to restore the concrete situation because vehicles’behavior is also affected by driver, weather, traffic and so on.This project is creating one new simulator with discrete time under microcosmic level. Comparing the traditional functions of simulation, discrete time method could restore the simulation by using steps separately. This kind of simulation could restore the behavior of vehicles more clearly, which is doing worthy for further researching and analysis.The simulator could design custom traffic models under different traffic situation. And it designed two scenarios of cooperative vehicles behavior:collision avoidance and car following model. Collision avoidance model is mostly using for the researching of cars moving from opposite direction. And car following model is simulating the usual traffic flow. It is using for the researching of keeping distance.The project is using MATLAB tool to visualize the custom designed scenarios. By using the collected data, map models could be drawn. Visualization performance could be used to express the characteristics of vehicles behavior.
