Traffic Intersection Scheduling System Based On ARM And Fuzzy Theory

With the development of economy and rise in level of urbanization, the vehicle volume of city increased rapidly and the traffic jam become more serious. We must take some measures to deal with the serious traffic jam that will counterwork our economy development. To urban road, the key is intersections where all traffic streams converge and turn. In China city, the mixed traffic of intersections makes order become rouge and tumble. This situation becomes more serious than before. In traffic engineering field , more importance has been attached to how to make the use of existing road, increase traffic capacity as well as relieve congestion in intersections as much as possible by means of scientific reasonable measures.The subject of the design is"traffic intersection scheduling system based on ARM and fuzzy theory."The system uses Samsung S3C44B0X to control the traffic intersection. It uses vehicle detection sensor to detect the cars flow, and according to the cars flow the system uses fuzzy algorithm to adjust automatically traffic lights time and complete the traffic junction management. This system design and product hardware circuit and software flow, including the following parts: the main program, fuzzy subprogram, time and signal lights subprogram.
