Direct Traffic Incident Detection Based on Video Technology

Expressways and urban expressways are the main roads for China's road transport and urban road transport. It has many characteristics such as fast speed and high flow rate. Once a sudden traffic accident occurs, it can easily cause traffic accidents, seriously affecting the road's capacity and operations. effectiveness. In the daily traffic operation and traffic management, if only relying on artificial reports, television monitoring and other non-automatic detection methods to discover traffic incidents, it is not only a waste of large amounts of resources, but also not comprehensive and timely, and brings hidden dangers to traffic safety. Therefore, the technology of automatic detection of traffic incidents has increasingly become a research hotspot of intelligent transportation, aiming at quickly discovering the location of traffic incidents at the first time and facilitating the timely handling of traffic incidents.

Traffic incidents refer to traffic situations such as accidental traffic accidents, broken down vehicles, bad weather, scattered cargo, road maintenance, sports events, and scale assembly. The parking, retrograde, slow traffic, congestion, pedestrian crossing, and traffic accidents that occur on expressways and on the urban expressways are traffic events that need to be controlled and controlled. When these traffic incidents are discovered, the automatic detection system for traffic incidents can immediately report an alarm, automatically record violations and violations, and quickly dispose of traffic incidents to eliminate potential safety hazards and reduce traffic accident losses.

Overview of Video Detection Technology for Traffic Incidents Automatic Detection Method for Traffic Incidents The research methods for traffic incident detection are divided into automatic and non-automatic detection methods. Non-automated technologies mainly include manual reports and television monitoring. Automatic technologies mainly include direct and indirect detection methods. The direct detection method is a video-based processing method that directly detects traffic events through a traffic incident video detection algorithm. Indirect detection method is a kind of processing method based on traffic flow parameters. It integrates traffic flow data to detect traffic events through pattern recognition, mathematical statistics, traffic model, and artificial intelligence.
