Description
Technical Field
The invention relates to the field of traffic signal control, in particular to a pedestrian and vehicle self-perception early warning system for a sidewalk based on a piezoelectric road surface.

With the popularization of private cars, more and more people choose the private car to go out, and the number of traffic accidents also shows an ascending trend. Researches show that traffic accidents frequently occur on sidewalks, and the time period is mainly concentrated at 4-6 pm, and the time period is the off-duty peak of students who go to school and office workers. With the popularization of smart phones, more and more 'head-lowering families' appear on roads, and even some drivers can occasionally stare at mobile phone reply information in the driving process. This further aggravates the occurrence of accidents on the sidewalk. There is also data showing that the probability of a driver giving a pedestrian at late night is reduced, depending on the speed of travel and night vision.
At present, most areas still stay at traffic lights to control people and vehicles to pass through, and voice 'red light crossing over the line' broadcasting devices are additionally arranged in the small areas.
