Application of vision sensing technology in urban intelligent traffic control system

With the acceleration of urbanization, the increasingly complicated urban traffic conditions and the continuous expansion of the overall scale have posed great challenges to urban traffic management. It is necessary that Intelligent Transport System is introduced for the future development of urban traffic management. Based on this background, the visual sensing technology is applied to the intelligent traffic control system. The CCD camera with 5 million resolution is designed and used to analyze real-time traffic entering at each intersection of urban road and calculate the traffic volume of each lane and queue, such as the vehicles length, average waiting time and other traffic parameters, which could provide real-time data to the signal light control system for dynamic signal parameter configuration to achieve intelligent single-point light signal control, trunk control and regional control. The system can be popularized and applied in the fields of intelligent signal light control and traffic information collection.
