Description
Technical field
The present invention relates to field of intelligent transportation technology, and in particular to one kind can carry out vehicle and vehicle/pedestrian's progress is two-way
The prior-warning device of early warning.
Background technique
It is shown according to mechanism survey data, the traffic accident at intersection of no control mode of transportation accounts for national traffic accident
33.83%, death toll accounts for the 32.49% of annual toll on traffic.Just there is a pedestrian by vapour within average every seven minutes
Vehicle is wounded, and every two hours left and right just has a pedestrian to capture life by traffic accident.Especially on state's provincial highway, County Highway, with village
The non-lamp control crossing that the village intersects, pilot's line of vision is limited, if pedestrian, non-motor vehicle are pierced by from crossing go across the road suddenly, easily
Driver is caused to have little time to slow down and cause traffic accident.Especially the traffic accident accounting caused by night-time hours is very big,
And often major casualties are in the majority, lack the generation that effective technological means are prevented accident always.Rather than lamp control crossing
The probability of generation accident is higher with respect to the probability at lamp control crossing.Currently, it is all detection row that non-lamp control crossing early warning system is most of
People has crossing behavior, and how far there is no be monitored vehicle distances.
Particularly, mountain road is in the key points and difficulties of traffic administration, especially mountain road by mountain peak or other barriers
" elbow the is curved " section for hindering object to obstruct the view, these roads generally only have two lanes up and down, due to lacking effective prompting
Device, easily generation traffic accident, though some places using the facilities such as convex lens carry out traffic reminding, be limited to installation site and
Reflection angle reminds effect generally unsatisfactory.
Therefore, how prior art defect is solved, is urgent problem now.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide vehicles at a kind of non-lamp control intersection or bend two sides
With the two-way prior-warning device of vehicle/pedestrian, with solve non-lamp control crossing or " elbow is curved " section etc. can not have in the prior art
Effect early warning pedestrian and vehicle lead to the technical issues of traffic accident easily occurs.
The present invention is achieved by the following technical solutions:
The present invention provides vehicle at a kind of non-lamp control intersection or bend two sides and the two-way prior-warning device of vehicle, the device packets
Include first information acquisition device, for showing that the first display device, the second information of first information acquisition device acquisition information are adopted
