Problems solved by technology
However, tunnels are usually built in mountains, the light is poor, and the width of the tunnel is generally narrow due to the influence of the strength of the mountain. Once traffic congestion occurs in the tunnel, the vehicles that are about to enter the tunnel cannot be known in advance, which will easily lead to more and more serious congestion. Even lead to safety accidents, there is a greater safety hazard
At present, most of them rely on on-duty personnel for control, which is a waste of manpower and low work efficiency

Embodiment
[0054] Such as Figure 1-2 As shown, a road condition management system based on the number of vehicles in the tunnel or road, including the left-hand lane road condition warning subsystem, the right-hand lane road condition warning subsystem, the road central control room alarm and the road condition warning display; the number of road condition warning displays There are at least two, and they are respectively set at a certain preset safe distance in front of the two entrances of the tunnel; the specific preset safe distance can be set according to the actual situation, and the function is to enable the driver according to the traffic conditions in the tunnel displayed on the road condition warning display. Road condition information and road condition warning information to make adjustments to driving route and driving speed;
[0055] The left-hand lane road condition warning subsystem includes a first PNP photoelectric sensor group SG arranged at the entrance of the left-h...

The invention discloses a road condition management system based on the number of remaining vehicles in a tunnel or on a road. The road condition management system comprises a left lane road condition early warning subsystem, a right lane road condition early warning subsystem, a road central control room alarm and a road condition early warning display. The left lane road condition early warning subsystem and the right lane road condition early warning subsystem respectively send the calculated road condition information and the road condition change trend to the road central control room alarm for reminding an operator on duty to check and monitor whether a traffic accident occurs or not in real time, and simultaneously send the road condition information and the road condition change trend to the road condition early warning display for reminding drivers who do not drive into a tunnel or road. According to the invention, a driver going to enter a tunnel or road can be informed of the road condition information and the road condition change trend in the current tunnel or road in advance within a certain preset safe distance, so that the driver has enough time to adjust the driving route and the driving speed in time, traffic congestion in the tunnel or the road is effectively prevented, and potential safety hazards are reduced.
Description
technical field [0001] The invention relates to the technical field of traffic management, in particular to a road condition management system based on the number of vehicles remaining in tunnels or roads. Background technique [0002] With the rapid development of urban construction in our country, the number of expressway tunnels is increasing. However, tunnels are usually built in mountains, the light is poor, and the width of the tunnel is generally narrow due to the influence of the strength of the mountain. Once traffic congestion occurs in the tunnel, the vehicles that are about to enter the tunnel cannot be known in advance, which will easily lead to more and more serious congestion. Even lead to safety accidents, there is a greater potential safety hazard. At present, most of them rely on on-duty personnel for control, which wastes manpower and lowers work efficiency. Contents of the invention [0003] In order to solve the above problems, the present invention ...
