Vehicle traffic lights control method for controlling the approach speed of the vehicle approaching the crosswalk in the protected area

摘要

The present invention relates to a vehicle traffic light control method for controlling the access speed of a vehicle approaching a pedestrian crossing in a protected area, the present invention in order to prevent a safety accident of a pedestrian occurring at a pedestrian crossing in which a pedestrian traffic light is installed in the protected area, In the vehicle traffic light control method for controlling the driving speed of a vehicle approaching the crosswalk based on the visible motion of the pedestrian traffic light using a radar, all driving approaching the crosswalk through the vehicle traffic light Displaying a red signal on the vehicle; Determining a driving speed and a proximity distance of a driving vehicle approaching the crosswalk using the radar; When the driving vehicle approaches the crosswalk within a preset distance and is in a constant speed driving state that complies with the speed limit of the protected area, and the pedestrian traffic light displays a red signal, the driving vehicle through the vehicle traffic light Changing and displaying a red signal to a green signal until passing through the crosswalk; And when the driving vehicle approaches the crosswalk within a preset distance and violates the speed limit of the protected area, or when the pedestrian traffic light displays a green signal, the red displayed on the vehicle traffic light. It provides a vehicle traffic light control method for controlling an approach speed of a vehicle approaching a pedestrian crossing in a protected area, including the step of maintaining a signal. According to the present invention, by inducing a deceleration of a driving vehicle in a protected area and driving at a cruise, it prevents traffic accidents of children with low cognitive ability, impulsive, slow reaction, and lack of agility for dangerous situations, as well as in the event of a traffic accident. It can significantly reduce the fatality rate from accidents. When the above-described decelerated driving vehicle reaches a constant speed driving state, a green signal is quickly displayed on a vehicle traffic light, thereby preventing a child traffic accident and inducing smooth communication of a vehicle approaching an intersection.
