Research On Intelligent Traffic Control Of Urban Intersection

With the continuous development of the city, the city’s traffic problems increasingly become a common problem in major cities. The city intersection as an important node in the city’s transportation hub, intelligent control its traffic signals, will play a crucial role in modern cities and urban intelligent process. How to use limited transportation resources, how scientific and rational urban intersection traffic signal control, to maximize the capacity of the city intersection, it has always been an important topic in the field of urban transport engineering research. Integrated technology to develop advanced information technology, computer technology and associated control algorithms implemented at city intersections and traffic lights intelligent control system can significantly reduce the cost of traffic operation and management, improve transportation efficiency. The continuous development of related technology and theory of intelligent control, the control system of urban intersection traffic signal provides a new solution.Firstly, urban intersection traffic signal intelligent control technology research background and significance are described in study after study researchers at home and abroad, combined with China’s specific national conditions, analysis of existing urban intersections Run the model and its Improve. Then, it introduces the related technologies and systems Intelligent Urban Traffic Signal Control Systems evaluation, depending on the application and Urban Intersection Signal Control, the system needs analysis from functional and non-functional aspects. On the basis of the above system requirements analysis, urban intersection signal control system for the overall design, detailed design of the system design and simulation models, and thus presents intelligent urban traffic signal based on fuzzy logic and genetic algorithms Control System. Finally, the system of the system operating environment, from console systems and simulation runs.Finally, intelligent urban traffic signal control system functional modules to achieve the simulation analysis, and with the traditional timing control system were compared, the results show that the designed urban traffic signal intelligent control system of the vehicle at the intersection in each direction reach under the similar circumstances, in terms of the average delay time, than traditional urban intersection control method has a large advantage and reached the system design goals.
