Smart Crosswalk System
Recognizes pedestrians in the crosswalk waiting area, links them to the signal, and displays warnings when vehicles approach to prevent accidents.
Solution
An intelligent traffic safety system that detects pedestrians and approaching vehicles in real time and links multiple safety devices to create a safe crossing environment
Using video recognition technology, the system detects pedestrians waiting at or crossing the crosswalk and approaching vehicles in real time. It analyzes pedestrian movement and signal status to coordinate a range of safety devices, including pedestrian signal extension, voice guidance, VMS displays and in-ground pedestrian signals. It is an intelligent traffic safety system that helps pedestrians cross safely and alerts drivers to pedestrians and hazards in advance, preventing traffic accidents in crosswalks.
- Detects pedestrians waiting, entering and crossing in real time to extend pedestrian signals and support safe crossings
- Links VMS, voice guidance and in-ground pedestrian signals according to signal status and hazards, providing real-time safety information to pedestrians and drivers
Components
Main components
Camera
- Collects real-time video through high-definition cameras and detects a wide range of objects, including pedestrians, bicycles and personal mobility (PM) devices, through deep learning-based video analytics
Red signal countdown display
- Shows the remaining green crossing time and remaining red waiting time of the pedestrian signal in numbers and graphics, helping pedestrians read signal information intuitively and cross safely
Video recognition software
- Analyzes depth information for the crosswalk and waiting area to detect pedestrians reliably day and night, and tracks movement paths to recognize waiting, entering and crossing in real time
In-ground pedestrian signal auxiliary device
- Collects pedestrian signal status from the traffic signal controller and shows a synchronized signal on the in-ground display, improving signal awareness and visibility for pedestrians
VMS display
- Displays information such as crossing in progress, jaywalking, emergencies and public service messages as text, images and animations based on signal status and pedestrian detection, providing real-time safety information to pedestrians and drivers
Voice guidance device
- Automatically broadcasts voice guidance on signal changes, jaywalking and hazards in conjunction with pedestrian detection and signal status, helping pedestrians recognize signals and cross safely
Strengths
Key features
Pedestrian actuated signal and signal extension
