The invention discloses a pedestrian early warning method, device and electronic equipment at urban road intersections. The invention uses the four aspects of pedestrian speed, vehicle speed, pedestrian area and driver's state as the judgment basis to carry out risk assessment for pedestrians passing through the intersection. Early warning, so as to output different collision warning levels, so as to send a collision warning prompt to the driver of the vehicle, and send a warning reminder to pedestrians in combination with the luminous signs at the intersection, voice early warning devices and zebra crossing warning lights; through the above design, the present invention integrates Considering the factors affecting the safety of pedestrians, the collision warning level of pedestrians passing through the intersection is accurately obtained, and two-way warnings can be realized for drivers and pedestrians. Therefore, the accuracy and timeliness of pedestrian warning can be realized, thus effectively Reduce the risk of traffic accidents at intersections.
Description
A pedestrian warning method, device and electronic device at an urban road intersection technical field The invention belongs to the technical field of early warning of pedestrians at urban road intersections, and is specifically related to a kind of pedestrian at urban road intersections Early warning method, device and electronic equipment. Background technique With the improvement of people's living standards, the frequency of use of vehicles in people's lives is getting higher and higher, and vehicles give people While life brings convenience, it also brings traffic accidents; at present, road vehicles collide with pedestrians and cause traffic accidents. This happens frequently, which brings huge loss to people's life and property safety. According to the statistics of the National Bureau of Statistics, as of the end of 2018, the national traffic accident data has exceeded 240,000 Since then, the number of people killed due to various traffic accidents has rea...
