Intelligent projection zebra crossing control method and intelligent projection zebra crossing device

Abstract

The invention discloses an intelligent projection zebra crossing control method and an intelligent projection zebra crossing device, wherein a stop line and the projection of a zebra crossing are controlled according to the lighting states of a pedestrian traffic light and a road traffic light, and the position of the stop line projected by a stop line projector is controlled to be far and near from the center of an intersection according to the number of waiting pedestrians in a pedestrian waiting area on the left side of the advancing direction of a road; the projection of the zebra crossing is divided into a first zebra crossing and a second zebra crossing, the first zebra crossing and the second zebra crossing are respectively indicated by forward arrows with opposite projection directions according to a rule of moving forward to the right, and the width of the first zebra crossing and the width of the second zebra crossing projected by a zebra crossing projector are controlled according to the number of people waiting in pedestrian waiting areas on the left side and the right side of the road in the forward direction. According to the invention, the zebra crossing projection mode and the transverse width are adjusted to shorten the time for the pedestrian flow to go across the road, so that a certain improvement and guidance effect is achieved on the traffic condition.

Description

technical field [0001] The invention relates to a method and device for controlling a projected zebra crossing, in particular to an intelligent projected zebra crossing control method and an intelligent projected zebra crossing device. Background technique [0002] Zebra crossings are generally composed of multiple parallel white solid lines. The function of zebra crossings is to guide pedestrians to cross the road safely. Traditional zebra crossings are printed on the road with white paint, providing pedestrians with passageways and traffic reminders. However, in actual use, traditional zebra crossings are prone to problems such as pollution and damage. At the same time, because they are not self-adaptive, they cannot adjust themselves according to changes in traffic conditions to achieve the purpose of ensuring pedestrian safety and improving traffic conditions. [0003] Based on the above problems, the patent "Pavement Prompt Unit and Intelligent Zebra Crossing" (applica...

AI Technical Summary

Problems solved by technology

Although the above-mentioned method can restrain and warn pedestrians from crossing red lights, it does not give full play to the huge advantages of system flexibility in projection mode. The above-mentioned patents do not consider and utilize the role of zebra crossing in guiding traffic flow.
