Abstract

A wearable pedestrian safety radar system including a harness with a pocket and a portable radar speed detection and display device to be worn on the front and back of the harness by a pedestrian while on a roadway. The device includes a radar system, LED lights, a microcontroller, a proximity sensor, a camera, a strobe light, an audible alert unit and a vibration unit. The device detects a speed of an on-coming motor vehicle. If the vehicle is exceeding a predetermined speed limit, the speed is displayed on the device. If the vehicle does not slow down below the speed limit within a distance detected by the proximity sensor, the camera records the vehicle while the strobe light blinks to warn the driver of the recording. The audible alert unit and vibration unit alert the pedestrian. The system may be used to relay data to a law enforcement agency.
