The detection radar 200 is a component that detects an object in a crosswalk. Here, objects include pedestrians. The detection radar 200 is installed on a pole of a traffic light. A crosswalk is formed in the second lane, and generally a crosswalk is installed at a location where a vehicle turns right in the first lane and enters the second lane, that is, at a point where a curve ends. In this crosswalk, there are frequent accidents between unprotected right-turning vehicles and pedestrians, especially due to obstruction of vision by the A-pillar.

The detection radar 200 is installed on a pole of a traffic light installed in the crosswalk, and detects an object by irradiating a laser toward the crosswalk. Here, the detection radar 200 may detect the presence or absence of an object from the time when the laser is irradiated and received again.

In addition, a voice module 400 is installed on the pole of the traffic light. The voice module 400 is a component for outputting a voice message to a pedestrian. More specifically, it is a configuration for outputting a warning sound or a warning message to a pedestrian.

Accordingly, the driver of the vehicle driving in the first lane can confirm that the traffic light of the crosswalk in the second lane is a walking signal when the vehicle entry prevention rod 100 emits light. Accordingly, even if there is a blind spot due to the A-pillar, it is possible to recognize that there is a high possibility that there are pedestrians in the crosswalk. In addition, more preferably, it is possible to prevent a more reliable accident by not turning right since it can be known that it is already a walking signal before turning right.

In addition, the control unit 500 receives whether the first sensor 300 detects a vehicle when the traffic light is a walking signal, and outputs a voice message through the voice module 400 when the first sensor 300 detects a vehicle. do.

Specifically, when the applied pressure is released after the first sensor 300 detects a pressure higher than a predetermined level, it is recognized that the tire of the vehicle has passed over the first sensor 300 and the driving of the vehicle can be sensed. It is preferable that the first sensor 300 be installed at the boundary between the first lane and the curve, or installed close to the curve.

When the traffic light of the crosswalk is changed to a walking signal at the time when the vehicle leaves the first lane, there is a possibility that the vehicle enters the crosswalk even if the vehicle entry prevention bar 100 emits light.

Accordingly, in the case of a walking signal, when the first sensor 300 detects vehicle driving, the controller 500 outputs a voice message through the voice module 400 to warn the pedestrian that a vehicle may enter. can do.
