Description
Technical field
The present invention relates to cross walk safety device.
Background technology
Cross walk relies on traffic lights to ensure traffic safety usually.But still always occur that people's car passes through the situation of cross walk in practice simultaneously, and often therefore cause dangerous situation.The technical scheme solving cross walk safety problem has a lot.Such as ZL200820119094.4 Chinese utility model patent, it discloses a kind of Crosswalk warning board.The technical scheme that this patent adopts utilizes flashing lamp to make the signal lamp at cross walk place more eye-catching.ZL201120155466.0 Chinese utility model patent and KR19980022414 korean patent application then warn the pedestrian passing through cross walk violating the regulations by warning system.The scheme of No. ZL200420150519.X Chinese utility model arranges horizontal bar to walk to prevent pedestrians disobeying traffic rule at cross walk place.These schemes all lay particular emphasis on the management to pedestrian.But we find, turning vehicle is a more serious problem and danger at the row of robbing at cross walk place.This turning vehicle rob row, part is because driver have ignored the traffic rules of turning and allowing and keeping straight on, and is on the other hand because the position of the traffic lights at cross walk place makes driver be difficult to see.
Summary of the invention
The present invention aims to provide a kind of cross walk safety device, it can not only reduce the possibility that pedestrians disobeying traffic rule passes through, also turning vehicle can be reminded when cross walk gives a green light to dodge the pedestrian normally passed through simultaneously, thus greatly reduce the danger at cross walk place.
According to cross walk safety device of the present invention, there are cross walk traffic lights, the roadside that this cross walk is other arranges fixing contents, it holds within it with when the traffic lights of cross walk are red light, one can being warned article locking, and unlock when the traffic lights of cross walk are green light, described warning article can be taken out, carry when walking cross walk for pedestrian, thus prompting vehicle driver, now cross walk green light, pedestrian has right of way, and vehicle should be dodged.
Because pedestrian carries warning article when crossing street, the driver of turning vehicle just learns that the traffic lights of now cross walk are green light, thus the pedestrian of right of way is dodged in parking.Moreover, and when traffic accident appears in cross walk also easily responsible party is judged.That is, when pedestrian cross walk passed through has staff to hold described warning article, if there is Vehicular impact pedestrian, must be that vehicle driver's all responsibility is broken rules and regulations.Otherwise if when vehicle bumps against pedestrian, cross walk not having the pedestrian of hand-held described warning article, is then probably pedestrian running red light.
