Problems solved by technology

[0004] The shortcoming of prior art is: but the traffic situation in the highway tunnel is often difficult to count, if the tunnel is too long, just need to install multiple monitoring cameras in the tunnel, realize monitoring without blind spot, just can obtain the vehicle condition in the tunnel, its installation cost Too high, and the longer the tunnel, the higher the installation cost

Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 , 2 Shown: a kind of highway tunnel traffic identification method, is to carry out as follows:

[0031] Step 1: Arranging an entrance vehicle identification device 1 and an entrance vehicle speed detection device 2 at the entrance of the road tunnel, and an exit vehicle identification device 3 and an exit vehicle speed detection device 4 at the exit of the road tunnel;

[0032] The output terminals of the exit and entry vehicle identification devices and the exit and entry vehicle speed detection devices are all connected to the central processing unit 5;

[0033] The exit and entrance vehicle identification device 1 is a camera, wherein the entrance camera is set at 100m-350m away from the road tunnel entrance, and the exit camera is set at 100m-350m away from the road tunnel exit.

[0034] If it is a doubl...

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. [0003] Indirect detection mai...
