Abstract

The invention discloses a sidewalk pedestrian and vehicle self-sensing early warning system based on a piezoelectric pavement. The sidewalk pedestrian and vehicle self-sensing early warning system comprises a comprehensive indicating rod, a piezoelectric speed measuring device, a piezoelectric vehicle sensing device, a piezoelectric pedestrian sensing device and a sidewalk piezoelectric sensing device. The piezoelectric speed measuring device is arranged on the road surface on one side of the sidewalk, and is used for sensing the time difference before and after the vehicle runs by utilizing the piezoelectric road surface so as to obtain the running speed of the vehicle. The piezoelectric vehicle sensing device is installed in front of a red light vehicle stop line and used for detecting vehicles passing through the line in the red light period. The piezoelectric pedestrian sensing devices are buried in the two sides of a sidewalk and used for dynamically sensing waiting pedestrians. The sidewalk piezoelectric sensing device is arranged on a sidewalk and used for sensing the walking state of pedestrians. The comprehensive indicating rod is installed beside a sidewalk and used for displaying and reminding the state of pedestrians and vehicles. The early warning system can effectively perform early warning, ensures pedestrian safety, and reduces sidewalk traffic accident rate.

Description

Technical field [0001] The invention relates to the field of traffic signal control, in particular to designing a sidewalk and pedestrian vehicle self-sensing early warning system based on a piezoelectric pavement. Background technique [0002] With the popularity of private cars, more and more people choose private cars to travel, and the number of traffic accidents is also on the rise. Studies have found that most traffic accidents occur on the sidewalk, and the time period is mainly at 4-6 pm. This time period is the peak of students leaving school and office workers. With the popularization of smart phones, more and more "head-downers" have appeared on the road, and even some drivers will occasionally stare at their phones to reply to messages while driving. This has exacerbated the occurrence of sidewalk accidents. There are also data showing that the probability of drivers giving way to pedestrians in the middle of the night will decrease, which is related to driving spee...
