Description
Technical field
The present invention relates to field of traffic safety on the street crossing line (zebra crossing) of road, has police more particularly to a kind of
Show the drive recorder and its control method of the signal lighties of other vehicles, the vehicle for being provided with the drive recorder is horizontal in the people that passes through
During diatom (zebra crossing), when having pedestrian by Video Detection on front street crossing line (zebra crossing), with outside signal lighties
Form warning is with other vehicles of track to the left and right, the traffic safety of the zebra crossing that watches for pedestrians (zebra crossing).
Background technology
At present, in order to ensure the unimpeded of road, set crossing overwhelming majority someone's row on the section of Urban Streets
The traffic signal of zebra crossing (zebra crossing) and crossing warning mark, when vehicle passes through these zebra crossings, if sight line
It is obstructed, and not Reduced Speed Now, when unsighted direction someone rushes out, it is easy to vehicle accident occurs, when unsighted direction
People be to ride bicycle, electric motor car or tricycle to rush out, it is easier to there is vehicle accident.
Although traffic law is fixed：Motor vehicles pass through crossing when, should Reduced Speed Now；Meet pedestrian horizontal by people's row
Road, should Stop and give way.But in reality, the zebra crossing region of process is not had pedestrian seeing which by total some vehicle
When, so as to not Reduced Speed Now, some vehicles, at this moment can also give it the gun, when unsighted by zebra crossing in order to as early as possible
Direction zebra crossing on have pedestrian to rush out, have little time that Stop and give way, so as to there is vehicle accident.Especially taxi,
In Jing zebra crossing not Reduced Speed Now, its side line in the same direction is taken in has big driving in crossing to the dillies such as private car
Line front reduction gear or parking, the dilly of now these not Reduced Speed Now are easy to vehicle accident at crossing.
Certainly traffic method also specifies：Steer bicycle, electric bicycle, tricycle cross car lane on section, should
When implementation of getting off.But in reality, people are in steer bicycle, electric bicycle, tricycle in the zebra crossing on the section
When (zebra crossing), side's convenience, few people are got off implementations, in addition have in order to cross car lane as early as possible, can also accelerate to ride
OK, now, if just there is being the vehicle of not Reduced Speed Now in front when crossing is passed through, it is easy to which major traffic accidents just occur.
It is known that:Big driving when Jing crossings give precedence to pedestrian, if small-sized on the track in the same direction of its left and right sides
When vehicle and not Reduced Speed Now, it is easier to which vehicle accident occurs.Because the big vehicle body that driving was not only high but also length is roomy is just as wall
(as the common buses in city have 9 meters long, 2.5 meters high, air-conditioned coach has 11 meters long, 2.8 meters high), now it is big driving dead ahead
And the pedestrian on zebra crossing (zebra crossing) region of right front is the dilly Driver Vision on the track in the same direction of left side
Blind area, the dilly on the track in the same direction of left side are the zebra crossing (zebra crossing) of the dead ahead of big driving and right front again
Pedestrian vision dead zone on region；Pedestrian on the big dead ahead of driving and the Ren row Heng Dao Xian ﹙ Ban Ma Xian ﹚ regions of left front
It is the dilly Driver Vision blind area on the track in the same direction of right side, the dilly on the track in the same direction of right side is big driving again
Dead ahead and left front Ren row Heng Dao Xian ﹙ Ban Ma Xian ﹚ regions on pedestrian vision dead zone.So now dilly is driven
The person of sailing mutually goes into vision dead zone with the pedestrian on Ren row Heng Dao Xian ﹙ Ban Ma Xian ﹚, now, when Ren row Heng Dao Xian ﹙ Ban Ma Xian ﹚'s
There is pedestrian in blind area, due to can't see, dilly driver will be considered that no pedestrian passes through, even if there is pedestrian, pedestrian also can
It was found that the vehicle, so as to pedestrian can go slowly or wait, therefore dilly not Reduced Speed Now, or not parking give way；And people's row this moment
Pedestrian the dilly is can't see in blind area on zebra crossing (zebra crossing), will be considered that in front of zebra crossing (zebra crossing) again not
Have vehicle to pass through, even if there is vehicle also find pedestrian and Reduced Speed Now, give precedence to pedestrian, thus pedestrian quickly walking is horizontal in people's row
On diatom (zebra crossing).There is vehicle accident so as to cause the vehicle of not Reduced Speed Now and the pedestrian of quick walking.
Meanwhile, it is being provided with the zebra crossing (zebra crossing) of when red, is stopping having oversize vehicle when footpath green light, by
Dilly driver on the track of side is caused to produce the pedestrian's situation on zebra crossing (zebra crossing) in oversize vehicle vehicle body
Blind area, and many pedestrians often can be also done last " spurt " when footpath green light closes to an end,.Oversize vehicle is often started to walk
It is relatively slow, so when driving green light is lighted, on the track of side, dilly driver may think that nothing on zebra crossing (zebra crossing)
People, first is robbed head start, if someone's " spurt " on Ren Hangheng roads line ﹙ speckles horse line ﹚ this moment, it is possible to which traffic thing can occur
Therefore, therefore on the Ren row Heng Dao Xian ﹙ Ban Ma Xian ﹚ for having when red, when vehicle driver is to the row on zebra crossing (zebra crossing)
People's situation can also occur vehicle accident when producing blind area.
Jing is looked into, and the outer lamp on current automobile is mainly used in the traffic safety of vehicle and the driving behavior by vehicle
Prompting rear car and vehicles and pedestrians around note this car, are not also documented and apply：When the front zebra crossing (speckle of this car
Horse line) on when having pedestrian, on the track in the same direction of open signal lamp warning both sides, other vehicle drivers answer Reduced Speed Now, give precedence to pedestrian
Case.On the track of side, other vehicle drivers are pointed out by observing the signal lighties of this car in the same direction, are confirmed by the body shadow of this car
Ring, whether have pedestrian in the region of blind area on the zebra crossing (zebra crossing) of formation, so as to reduce zebra crossing (zebra crossing)
