Smart pedestrian light crossing control solution

1.Program Objectives

The Smart Pedestrian Light Crossing Control Program aims to improve the safety and convenience of pedestrian crossings through intelligent technical means, while optimizing traffic order, alleviating the problem of insufficient police force, and reducing the occurrence of traffic accidents.

2.Technology and Functions

Pedestrian detection and warning: Use cameras, infrared sensors, radars and other equipment to monitor pedestrian dynamics in real time. When pedestrians approach the zebra crossing, the system automatically activates warning functions such as voice prompts and LED flashing to remind pedestrians to pay attention to the status of traffic lights.

Capture and exposure of illegal behaviors: The system can automatically capture pedestrians who run red lights, expose illegal behaviors in real time through the high-brightness display screen at the intersection, and support illegal behavior recording as a basis for law enforcement.

Multimodal interactive design: Combine voice prompts, LED screen displays, face recognition and other methods to cover the needs of different groups and improve the interactive effect.

Ground warning system: Install LED luminous tiles or road studs in the zebra crossing area, display colors synchronously with traffic lights, clearly outline the zebra crossing area, remind drivers to slow down and give way, and provide ground reminders for people who look down at their phones.

Intelligent signal control: Dynamically adjust the timing of traffic lights according to real-time traffic flow and pedestrian needs, reduce pedestrian waiting time, and avoid pedestrians risking running red lights due to waiting too long.

3.System architecture

Independent brain, no interference: The intelligent pedestrian integrated column and the ground equipment controller have separate main control units and distributed operation. The failure of one device will not affect the operation of other devices.

Low-voltage power supply, safe and reliable: The ground equipment system uses DC 24V to operate, avoid leakage risks, and ensure the safety of pedestrians and vehicles.

Communication and data transmission: Through 4G and other communication modules, the data transmission between the front-end equipment and the back-end platform is realized, the intersection information is transmitted in real time, and it supports docking with mainstream signal control systems.

4.Application scenarios and cases

School surroundings: In the road sections near the school, the pedestrian crossing application button is used for control. When a pedestrian presses the button, the signal light automatically switches to the pedestrian traffic mode to ensure the safety of students going to and from school.

Commercial blocks and transportation hubs: In areas with large pedestrian flow, intelligent luminous zebra crossings and integrated signal lights are used to improve the safety of pedestrian crossings and optimize traffic order.

Non-light-controlled intersections: For intersections without signal lights, a variety of triggering methods such as mechanical buttons, infrared sensors, and camera recognition are used to automatically switch the signal light status and warn vehicles and pedestrians in both directions.

5.Advantages and effects

Improve pedestrian safety: Reduce conflicts between people and vehicles and traffic accidents through all-round sound and visual warnings.

Relieve insufficient police force: With non-site automatic evidence collection, the system can work around the clock and effectively curb pedestrians from running red lights.

Optimize traffic efficiency: Intelligent signal control and ground warning systems reduce pedestrian waiting time and improve intersection traffic efficiency.

Energy saving and environmental protection: Some equipment uses solar power to reduce energy consumption and carbon emissions.

The smart pedestrian light crossing control solution provides pedestrians with a safer and more convenient crossing experience through intelligent and humanized technical means, while optimizing urban traffic management.
