The solar radar speed sign is designed to address the increasing issue of vehicle speeding, which has led to frequent traffic accidents and posed challenges for traffic management. By leveraging radar technology, this system effectively monitors and displays vehicle speeds, promoting safer driving behaviors and reducing accidents caused by overspeeding. It consists of a radar detector, a rear-end speed display module, and passive reflective patterns and text, forming a comprehensive solution for speed warning and enforcement.
