AI Technical Summary

Technical Problem

Conventional zebra crossings lack active warning mechanisms to alert drivers about pedestrians, leading to increased risks of collisions, especially in adverse conditions, and existing systems fail to provide timely deceleration or braking commands to vehicles.

Method used

A pedestrian crossing warning device that uses sensors to detect pedestrians and vehicles, activating warning lights with adjustable intensity and mode based on distance, and sending braking commands via V2X technology, powered by a piezoelectric energy generation system.

Benefits of technology

Enhances driver awareness of pedestrians, improves visibility, and reduces collision risks through graded warnings and active braking, ensuring improved traffic safety at zebra crossings.
