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.
