Smart Pedestrian Crossing System

Operating Scenarios

The system supports four flexible, programmable scenarios:

1. Loop Control – Pedestrian Priority

• When the pedestrian push button is pressed, the system activates the green signal for pedestrians and the red signal for vehicles.
• An underground magnetic sensor, placed 50 meters from the intersection, detects approaching vehicles.
• After 5 seconds from button activation, vehicle traffic is stopped, and pedestrians are allowed to cross safely.

2. Congestion Management Mode

• Automatically prioritizes pedestrians or vehicles based on real-time congestion levels detected by sensors.
• Ensures smooth traffic flow and fair signal time distribution.

3. Radar-Based Pedestrian Priority

• Radar detects vehicles 80–100 meters from the intersection.
• If no speeding violation is detected, vehicles are allowed to pass within their allocated time.
• If a speeding vehicle is detected, its signal turns red for an additional 10 seconds to allow pedestrians to cross safely.

4. Simple Push Button Activation

• Pedestrians can activate the green signal by pressing a button.
• Signal times for both pedestrians and vehicles are pre-configured.

3. Centralized Control Unit

• Modular design, expandable to suit intersection size.
• Controls up to 32 intersections simultaneously.
• Supports multiple modes, including fixed time and green wave.
• Synchronization between intersections via GPS.
• Connectivity through RS485 or Ethernet.
• Runs on a smart card-based Linux operating system.
• Compatible with high-level communication protocols.

4. User Management & Software

• Multi-level access permissions for users.
• Logs all user actions for full accountability.
• Cloud-based remote access after device configuration.
• Remote programming via RS485 cable or internet.
