Problems solved by technology
The traffic data that various types of detectors can detect include one or more of traffic flow, speed, occupancy rate, travel time, queue length, license plate, headway, vehicle trajectory, etc., but no type of detector can cover All traffic parameters
Moreover, with the ever-changing requirements of urban traffic management and control, the detection of traffic volume is far from meeting the needs of system planners, managers and designers, and more and more detection requirements have been proposed for daily traffic management and control, such as traffic accidents, congestion levels, illegal parking, etc.
Therefore, pure traffic data detection can no longer meet the front-end information requirements of modern traffic

The invention discloses an urban traffic perception system based on millimeter-wave radar, which belongs to the technical field of road traffic state detection, and solves the problem that the traditional traffic information detection system cannot meet the information requirements of the front section of modern traffic. It mainly includes data detection module, data transmission module, data receiving module, data processing module, data analysis module and data sharing module, as well as simple and efficient data processing method and analysis method. Data detection and information estimation, and a set of functional modules and implementation methods of the traffic perception system are proposed, which realizes the precise positioning of accidents, and also realizes the estimation of accident information required by other traffic management and control. Strong economic and social benefits are of great significance in the field of intelligent transportation technology.
Description
technical field [0001] The invention belongs to the technical field of road traffic status, and in particular relates to an urban traffic perception system based on millimeter wave radar. Background technique [0002] With the continuous improvement of national urbanization and economic level, the number of urban motor vehicles and the travel demand of residents are increasing rapidly, and the increasing traffic congestion, traffic accidents, exhaust emissions and energy consumption have become important factors affecting urban development and the construction of modern ecological civilization. obstacle. Through the vigorous development of new technologies such as cloud computing, big data, the Internet, and mobile Internet, the intelligent transportation system based on data perception has been further developed, especially in traffic planning and design, intelligent signal control, traffic guidance, and intelligent public transportation. etc. have been implemented and app...
