Technical Field
The invention relates to a safety warning system, in particular to an intelligent safety warning system for pedestrians and motor vehicles at an intersection.
Background
The phenomenon of 'ghost probe' in the traffic field refers to a scene that when the A vehicle goes beyond the B vehicle (also refers to that the A vehicle is in a stationary state on the way of running, vehicles on both sides or vehicles on one side) the A vehicle suddenly runs out of pedestrians or vehicles from vision blind areas such as the front of the head of the B vehicle, the tail of the reverse vehicle or buildings on both sides of a road due to the blocking of the vision of the A vehicle by the vehicles or obstacles. This phenomenon makes it difficult for a driver in driving to judge in advance, and often causes traffic accidents. In addition, the surrounding barrier and the green isolation belt of the construction road section are easy to relax vigilance due to good road surface passing conditions, but the non-motor vehicles and pedestrians suddenly come out of the surrounding barrier and the green isolation belt can make the straight vehicles worry about; the road entrance and the building are the same in shielding, because isolation belts are arranged between a general main road and an auxiliary road, and if pedestrians enter the main road, vehicles are difficult to find, and if double-service vehicles are too fast, danger is easy to occur; the crossroad and the T-shaped intersection are also high-incidence areas of ghost probe accidents; the danger index of the accident is very large, pedestrians and non-motor vehicles are the most damaged, private vehicles are easy to cause the accident due to 'ghost probes', and some operating vehicles and buses have the accident.
