Multi-lane tunnel traffic flow control system based on traffic monitoring

Abstract

The invention discloses a multi-lane tunnel traffic flow control system based on traffic monitoring. The system comprises components such as a monitoring module, a control module, a signal display module and an emergency processing module. The monitoring module is mainly composed of monitoring equipment with an image memory recognition function, and is used for recording and counting the number of vehicles in each lane at the entrance of a tunnel or inside the tunnel. The control module is mainly used for carrying out analytical processing on data counted by the monitoring module and sending a command for the signal display module and the emergency processing module. The signal display module is mainly composed of an LED signal lamp, and comprises a flashing light lamp, a traffic guidance screen and the like. The emergency processing module is used for triggering to send out an alarm after receiving an accident command sent by the control module and informing a tunnel control department of developing corresponding work. Under the premise of without influencing the existing traffic control system of tunnel, effective control for traffic flow in the tunnel is realized, the traffic environment inside the tunnel is improved, and the traffic efficiency and safety level are improved.

Description

technical field [0001] The invention relates to the field of traffic safety, in particular to a multi-lane tunnel traffic control system based on traffic monitoring. Background technique [0002] With the improvement of road construction technology, tunnels, as an important structure of road traffic, have also developed rapidly. As of the end of 2013, my country has built 11,359 road tunnels with a total length of 9,606 kilometers. While the scale of highway tunnel construction is expanding, tunnel traffic safety has also become an important topic of concern. A tunnel is a traffic structure buried in the ground, so it is difficult for outsiders to know the traffic conditions in the tunnel. Therefore, it is inevitable that sometimes a lane in a multi-lane tunnel suddenly becomes denser or smaller. The distribution is seriously unbalanced. The emergence of this situation will cause some drivers to ignore the regulations of "no overtaking" and "no lane change" in tunnel drivi...

Problems solved by technology

At the same time, according to the statistics of the transportation department, when the traffic density of the tunnel exceeds a certain threshold, the probability of traffic accidents will increase.
