Abstract

The invention discloses a highway tunnel traffic identification method, which is characterized in that 1. an inlet vehicle identification device and an inlet vehicle speed detection device, an outlet vehicle identification device and an outlet vehicle speed detection device are arranged; 2. a central processing unit obtains the information and speed of the inlet vehicles and the information and speed of the outlet vehicles, and the entering and exiting times of the vehicles are recorded; 3. practical traveling time is calculated; 4. the threshold value range of the traveling time of the vehicles normally and safely passing through the tunnel is determined; 5. abnormal vehicles are determined; 6. abnormal conditions occurring in the tunnel are determined; and 7. the number of the vehicles besieged in the tunnel and average queuing length are calculated and a traffic abnormal event alarming is sent. The invention has the obvious effect that the line laying is simple, implement is easy, cost is low, and real-time monitoring is carried out aiming to the highway tunnel traffic conditions so as to facilitate statistic data; and whether the abnormal conditions occur or not can be obtained in time, and the conditions in the tunnel after the abnormal conditions occur can be predicted.

Description

technical field

[0001] The invention mainly belongs to the technical field of road tunnel safety detection and monitoring, in particular to a road tunnel traffic identification method. Background technique

[0002] At present, my country's traffic anomaly detection is mainly divided into two categories: direct detection and indirect detection. Direct inspection includes manual on-site inspection and video inspection. Since the highways currently under construction in my country are generally equipped with TV surveillance cameras, video inspection has basically replaced manual inspection, allowing managers to monitor road traffic conditions in the monitoring center. With the development of pattern recognition, digital image processing and computer vision technology, video traffic anomaly detection system will be widely used in the field of traffic management and become an accurate and reliable data source for intelligent transportation system.
