Traffic warning system

Abstract

The traffic warning system of this invention includes a vehicle sensor, a plurality of pedestrian sensors, and a plurality of light sources electrically connected to the vehicle sensor and each of the pedestrian sensors. In this invention, the vehicle sensor generates a first activation signal after detecting a vehicle and the pedestrian sensors generate a second activation signal after detecting a pedestrian, thereby activating each of the light sources to emit warning light, so that the driver of the vehicle can clearly know that there are pedestrians crossing the pedestrian crossing, thereby providing a warning function.

Claims

1. A traffic early warning system, comprising: Vehicle sensors are installed on both sides of the pedestrian crossing to generate an initial start signal after a vehicle is detected passing by. A plurality of pedestrian sensors are deployed at both ends of the pedestrian crossing to generate a second activation signal after a pedestrian is detected crossing; and a plurality of light sources are electrically connected to the vehicle sensor and each of the pedestrian sensors and are installed on the pedestrian crossing, wherein each of the light sources emits light toward the middle of the pedestrian crossing when it simultaneously receives the first activation signal and the second activation signal.

2. The traffic warning system as described in claim 1, wherein, The vehicle sensor and each of the pedestrian sensors are pressure sensors, light sensors, or a combination of pressure sensors and light sensors.

3. The traffic warning system as described in claim 1, wherein, Each of these light sources is a light-emitting diode.
