Description

Vehicle entry prevention screen device for crosswalk {SAFE SCREEN APPARATUS FOR CROSSWALK}

The present invention relates to a vehicle entry prevention screen device for crosswalks, and more particularly, a crosswalk vehicle capable of preventing a safety accident by preventing a vehicle from entering the crosswalk when a pedestrian signal is signaled at a crosswalk such as a child protection zone. It relates to an entry prevention screen device.

In general, traffic lights installed at crosswalks repeat walking signals and vehicle signals sequentially according to a predetermined period, and blue (green) signals for pedestrians (walking signals) that allow pedestrians to walk while waiting at the crosswalk. When lights up, you will cross the crosswalk.

In addition, according to a signal installed on the road, drivers drive when a driving signal (green signal) is used, and stop driving when a driving prohibition signal (red signal).

At this time, when a pedestrian does not come into view, drivers may ignore the pedestrian signal at the crosswalk and pass through the crosswalk.

On the other hand, in recent years, traffic accidents at crosswalks in children's protection zones are frequently occurring, which is a social problem.

School zones are children's protection zones, and are generally implemented on roads within a radius of 300m from the main entrance of an elementary school or kindergarten.

In this school zone, the speed of automobiles is limited to within 30 km/h in Korea, but many vehicles violate this regulation speed, and as a result, many children are at risk of traffic accidents.

In particular, when recognizing a walking signal, such as young children, they are easily exposed to the risk of accidents because they enter the crosswalk without checking the presence or absence of a vehicle.Since their bodies are relatively small, they are not easily recognized in the driver's field of view, resulting in a traffic accident. There is a problem.

In addition, when it is difficult to secure a view at night or due to snow or rain, there is a problem that the frequency of accidents among the elderly is further increased.

On the other hand, when the green light of the pedestrian traffic light is lit on the roadway around the crosswalk, a stop line is provided for the safety of pedestrians crossing the crosswalk.

However, since there is no separate structure on the stop line, the driver often stops over the stop line, and there are cases where the stop signal cannot be confirmed because the traffic lights are covered by vehicles with high total height, such as a freight car, so that pedestrians feel a threat to safety. A problem arises.

In addition, pedestrians also often wait close to the roadway when the pedestrian traffic light is red or wait after getting off the roadway, and in this case, there is a high possibility that an accident may occur due to contact with the vehicle.

Accordingly, a technology capable of preventing a traffic accident at a crosswalk as described above has been developed.

As a related prior art, there is an intelligent safety blocking device for crosswalks disclosed in Korean Patent Publication No. 10-1061583.

These prior art technologies include a traffic light recognizer that detects the lighting state of traffic lights located around the crosswalk with a signal detection sensor, and the roadway at both ends of the crosswalk by a blocking bar that moves up and down according to the lighting state of the traffic light detected by the traffic light recognizer. The vehicle is equipped with a safety breaker that isolates and communicates with pedestrians crossing the crosswalk, and is provided on the center line of the roadway located around the crosswalk, and is synchronized with the lighting state of the traffic light detected by the traffic light recognizer. It is a configuration that includes a bollard that regulates the progress of

However, the prior art as described above can only visually warn that a vehicle enters the stop line of a crosswalk through the lighting of the bollard, but there is a limit in that it cannot physically block the entry of the vehicle to the stop line of the crosswalk. .
