Description

{SAFETY APPARATUS ON A CROSSWALK FOR PEDESTRIAN}

[0001] The present invention relates to a pedestrian safety device, and more particularly, to a pedestrian safety device for pedestrians in connection with a traffic light, which provides a virtual image of a pedestrian in a pedestrian crossing area to prevent a traffic accident The present invention relates to a pedestrian safety device provided with a virtual pedestrian image.

In general, a crosswalk is installed on a road so that a pedestrian can safely cross the road. In order to inform that there is a crosswalk at night, a warning light is turned on or a crosswalk is illuminated, So that the driver is alerted to safety.

However, if there are no pedestrians crossing the pedestrian crossing, there are people who run across the pedestrian crossing, ignoring the stoppage of the traffic light on the pedestrian crossing, . However, there is a dark place because there is no lighting device such as a street light around the crosswalk, which makes it difficult for the driver to easily grasp the pedestrian passing through the crosswalk.

Therefore, if the driver ignores the stop signal of the traffic lights installed on the crosswalk and drives the crosswalk, there is a risk of causing a traffic accident. Therefore, it is necessary to output a virtual pedestrian image on a pedestrian crossing regardless of whether the pedestrian is crossing or not, and a proper lighting device is installed around the pedestrian crossing so that the pedestrian passing through the pedestrian crossing can be easily recognized by the driver. There is a problem that it is not easy to install a separate lighting device around the traffic lights because it is economically burdensome.

In order to solve such a problem, a lighting device capable of illuminating a pedestrian crossing is installed on a signal lamp mount provided horizontally on the road surface at the top of a lap of a traffic signal for a vehicle.

When the illuminating device is installed on the signal lamp mount, the light emitted from the illuminating device may be diluted due to the light emitted from the illuminating device. When the illuminating device is installed on the signal lamp mount, There is a problem that the supporting crossbars and supports are bent or broken.

On the other hand, since a traffic light for a vehicle is usually installed near a safety line (or a stop line), the driver of the vehicle stopped at the safety line installed adjacent to the crosswalk can not visually confirm the signal lamp installed in the traffic light for the vehicle, It is troublesome to check the traffic light for crossing protection. In particular, if the width of the road is wide and the vehicle next to the vehicle is covered by the traffic light for the crosswalk, the driver can not confirm that the driver directly switches from the pedestrian signal to the vehicle signal. This increases the risk of accidents.

Korean Patent No. 10-1145955
