Embodiment 1

[0022] An expressway tunnel vehicle illegal behavior analysis warning device, including a tunnel entrance vehicle collection device, a tunnel exit vehicle collection device, a tunnel comprehensive analysis early warning device, a tunnel exit safety warning device, a tunnel entrance safety warning device, the tunnel entrance vehicle collection device When the vehicle enters the tunnel, the image sensor is used to obtain the vehicle photo according to the vehicle, and the license plate color and license plate number are automatically recognized, and at the same time, the non-video traffic flow counter is used for counting. And upload the identification number plate color, number, counting information and lane information to the tunnel comprehensive analysis early warning device, the tunnel exit vehicle collection device obtains the vehicle photo according to the vehicle through the image sensor when the vehicle drives out of the tunnel and automatically recognizes the number plate...

Embodiment 2

[0024] The tunnel comprehensive analysis early warning device includes a preset early warning output corresponding to a high-risk vehicle depot. The tunnel comprehensive analysis early warning device compares the queued vehicles entering the lane with the high-risk vehicle depot, and if the preset high-risk vehicle information is included, the corresponding early warning output is displayed through the early warning output module and the tunnel entrance safety warning device.

Abstract

The invention discloses a lane changing and overtaking early warning device and method for expressway tunnels, and relates to the technical field of expressway tunnel traffic management. The device comprises a tunnel entrance vehicle collection device, a tunnel exit vehicle collection device, a tunnel comprehensive analysis and early warning device, a tunnel exit safety warning device and a tunnelentrance safety warning device, wherein the tunnel entrance vehicle collection device and the tunnel exit vehicle collection device are both set according to the lanes; the tunnel entrance vehicle collecting device, the tunnel exit vehicle collecting device, the tunnel exit safety warning device and the tunnel entrance safety warning device are all connected to the tunnel comprehensive analysis and early warning device; and the tunnel comprehensive analysis and early warning device comprises a vehicle number plate and traffic flow data extraction module, a lane queue analysis module and an illegal early warning information output module. The lane changing and overtaking early warning device and method have the beneficial effects of carrying out early warning for the traffic risk and lanechanging in the tunnel and the overtaking illegal vehicles in real time at the tunnel exit and entrance, and reminding drivers to drive safely.

Description

technical field [0001] The invention mainly relates to the technical field of highway tunnel traffic management, in particular to an expressway tunnel lane change and overtaking early warning device and method. Background technique [0002] Expressway tunnels are the focus of traffic safety management and also the difficulty of traffic management. Illegal lane changes and overtaking in tunnels are the main causes of traffic accidents in tunnels. However, due to the poor lighting conditions and exhaust gas in the tunnel, the direct installation of illegal lane change and overtaking evidence collection devices in the tunnel has problems such as poor evidence collection photos, equipment lenses are easily polluted, heavy maintenance, and illegal evidence collection cannot cover the entire tunnel. [0003] The information management of highway tunnels belongs to the category of intelligent transportation (ITS), and usually has two technical directions. One is the tunnel informa...
