Description
Technical Field
The invention belongs to the technical field of traffic control, and particularly relates to a traffic guidance and alarm system.
Background
With the wider and wider coverage of the expressway in China, people can go out more and more conveniently, but the traffic problems caused by severe weather conditions (such as fog, ice and snow, high temperature, rainy days and the like) are also endless. In particular, "cloud", snow and ice, high temperature, rainy weather, which can be the most dangerous weather conditions on highways:
the 'cluster fog' is basically fog, is influenced by the microclimate environment of local regions, and is fog with thicker and lower visibility in the local range of tens to hundreds of meters. Because the fog is not matched with the large-scale atmospheric environment, the fog group can not only be found in the foggy weather, but also be possibly found in remote mountainous areas or rural areas under the condition of good weather conditions. Due to the fact that the 'cluster fog' prediction is difficult and the regional performance is strong, vehicles are difficult to be informed or warned in advance, the vehicles often drive into the 'cluster fog' region and cannot slow down at all, and serious traffic accidents are often caused.
The ice and snow also greatly influence the safety of the expressway, and the expressway has the characteristics of difficult prediction and forecast and strong regionality, so that vehicles are difficult to be informed or warned in advance, and serious traffic accidents are often caused.
For a high-temperature road section, the temperature of the road surface can reach thirty to forty ℃, and the friction causes the temperature of the tire surface of the vehicle to rise due to the high-speed running of the vehicle on the highway, and if the vehicle runs for a long time, the tire is easy to burst at high temperature, thus causing traffic accidents.
When the automobile runs in rainy days, the sight line is poor, the road surface is wet and slippery, and the road surface is accumulated in a heavy rain section, so that the influence on the high-speed running safety is great.
In addition, as the safety distance of a driver is too small, the high-speed traffic accidents are often caused by human factors such as fatigue driving and the like.
After an accident occurs, high-speed traffic is often influenced, high-speed congestion is caused, and particularly, once the accident occurs due to large traffic flow in holidays, large traffic congestion is caused, a vehicle behind cannot move for a long time due to congestion, and the specific situation of the accident in front cannot be known; in addition, after congestion occurs, due to the fact that drivers are not neat in quality level and careless, the vehicles are further crowded forwards and even occupy emergency lanes, traffic congestion is serious, or due to the fact that the vehicles are crowded and have traffic accidents such as scraping, difficulty and workload of dredging are further increased, rescue workers or law enforcement workers cannot enter rescue and law enforcement sites due to the fact that the vehicles are crowded and occupied emergency lanes, rescue time is delayed, and the law enforcement workers cannot conduct on-site command and evacuation timely.
In addition, once congestion occurs at a high speed, traffic control and shunting are required to be performed in time, further congestion caused by the fact that more vehicles run to the high speed is avoided, the existing traffic control is relatively late, shunting is not timely, and specific traffic control and shunting cannot be transmitted to traffic polices in jurisdictions at the first time.
