An Intelligent Guidance System for Pedestrian Crossing with Movable Laser Wall

Abstract

The invention relates to an intelligent guiding system, with a movable laser wall, for street crossing of pedestrians. The system comprises video collectors arranged at the two ends of a pedestrian zebra crossing respectively, video analyzers connected to the video collectors respectively, signal lamp controllers and a laser lamp controller connected to the video analyzers, laser lamps connected to the laser lamp controller, a V2I information emitter connected to the signal lamp controller, and vehicle-mounted information receivers arranged on motor vehicles respectively. The system satisfies the street crossing requirement of pedestrians to the largest degree, accords with street-crossing features of different types of pedestrians, can limit violated street crossing behaviors of the pedestrians effectively, and avoids disorder of street crossing in a crossing.

Description

technical field [0001] The invention relates to an intelligent guiding system for a movable laser wall for pedestrians crossing the street, which belongs to the field of intelligent transportation and also relates to the field of optoelectronics. Background technique [0002] Pedestrian crossing facilities are measures to ensure the safety, speed and convenience of pedestrians and vehicles in varying degrees. [0003] Among the existing pedestrian crossing facilities, the most common ones are plane pedestrian crossing facilities, such as pedestrian crossing, zebra crossing, pedestrian safety island, and crossing signal lights. The existing street-crossing signal lights are mainly based on the timing control mode, and the timing control is simple to use and set, but there are many defects. One is that when there are few or even no pedestrians needing to cross the road in a certain direction at a certain time period, the control machine will release pedestrians at a fixed tim...

AI Technical Summary

Problems solved by technology

One is that when there are few or even no pedestrians needing to cross the road in a certain direction at a certain time period, the control machine will release pedestrians at a fixed time and stop motor vehicles, greatly reducing the road traffic in a certain direction. traffic efficiency

Second, when a large number of pedestrians need to cross the road in a certain direction in a certain period of time (such as the intersection in front of a school or a factory), and there are fewer vehicles on the road at this time, the control machine still releases the machine at a fixed time. Moving vehicles prevents a large number of pedestrians from crossing the road for a short time, which will easily cause the phenomenon of "Chinese-style crossing the road" illegally crossing the road.

The third is that the existing signal light intersections are often equipped with auxiliary countdown display equipment. Although the countdown equipment can serve as a warning for the remaining time for pedestrians to cross the street, sometimes it often leads to the occurrence of pedestrians rushing to cross the street.

my country's traffic management departments mostly focus on education and safety publicity for pedestrians' illegal crossing behaviors. The existing governance methods cannot effectively restrain pedestrians' illegal crossing behaviors, and there is no reasonable legal basis for pedestrians' illegal crossing behaviors.
