The Research Of Multi-intelligent Vehicles Collaborative Control Methods Based On Miniature Traffic Intersection Environment

The multi-intelligent vehicles collaborative helps to solve the actual problem such as traffic accidents on crossroad and road congestion, can improve the security of intelligent transportation system, and run efficiently. Due to high costs using real vehicles for studying multi-intelligent vehicles collaboration control, and software simulation can’t reflect real time, so this paper carries out the research of multi-intelligent vehicles collaborative control methods based on miniature traffic environment platform.Firstly, in order to study better of multiple vehicles collaboration control at miniature traffic crossroad, It sets miniature traffic platform composed of the typical traffic scene and multi-intelligent vehicles, and establishes the team model of system, which can emulate the actual convoy system in dynamics and communication and so on. These are the basis of completing the more cars collaboration system control.Secondly, in order to meet the real-time and reliability requirements of multi-intelligent vehicles collaboration system based on miniature traffic environment, it uses the ZigBee communication technology to design wireless communication network for multi-intelligent vehicles collaboration and control on miniature traffic crossroad, to realize car-car and car-road communication modes to exchange information, and come true share of the car status and position in the system. It uses MAC layer and physical layer and application layer and network layer of ZigBee network OSI seven layer model structure, which improves reliability and real-time of multi-intelligent vehicles collaboration control system.Finally, in view of the miniature traffic intersection with traffic lights or not, It designs two different control algorithms. Under the condition of traffic lights, the main consideration is how fast, we use fuzzy control method based on GA to implement the intelligent vehicles through the intersection quickly. Under the condition of no traffic lights, it adopts conflict table control method to realize the safe passage of the vehicle and avoid the collision between vehicles. The experimental results show the effectiveness and efficiency of these two kinds of control algorithm.
