Description
Technical field
The utility model relates to traffic guidance technical field, in particular to a kind of highway driving based on lane grade lures safely
Guiding systems.
Background technique
National highway is since weather causes closing to have become the norm, because of the more frequency of traffic accident caused by extreme weather
It is numerous.As soon as the extremely low burst group's mist of dense fog especially visibility is at the head for inducing serious accident on expressway to autumn and winter
Number killer, has threatened the safety of area's public way in all parts of the country and the sustainable development of national economy.How to ensure
Extreme weather traffic safety improves vehicle pass-through rate and has become traffic control department urgent problem to be solved.
Phenomenon 1 at present: some roads are handed on road surface and install ground induced light on peace markings, usually work and are being always on mode
Or flash pattern, such mode have certain warning function, but cannot judge whether there is vehicle on road.
Phenomenon 2 at present: pass through and intelligent fog lamp apparatus for deivation (can show amber light and red light) is installed on the guardrail of both sides of the road.
When blocking the way road passes through without vehicle, road profile (constant or flashing) is shown with amber light；It is aobvious with red light when there is vehicle to pass through
It warns section (constant or flashing).This method that can show road profile has certain limitation, because driver opens
Vehicle is more the front lane of concern vehicle, rather than the entire road profile in front.But it on the whole can be to a certain extent
Prevent the generation of greasy weather rear-end collision.
Defect: highway is typically all to be made of multiply lane in practical application, is filled since existing intelligent fog lamp induces
Vehicle driving cannot be detected in which lane information, when other lanes have without vehicle in the safe range of the lane of traveling front by setting
Che Shi, front also can show vehicle by being mounted on the device display red light of road two sides, and such driver takes in front of lane
There is vehicle to reduce speed now, lane occupancy ratio is caused to increase, congestion is easily caused to cause some unexpected things instead.
The frequency that phenomenon 1 is flashed with lamp in phenomenon 2 generally cannot be adjusted, if it is possible to according to the vehicle in driving process
The fast frequency that amber light and blinking red lamp are controlled with slowly of speed, then can more play the warning for reminding driver safety to drive and make
With.
Cause the deficiency in phenomenon 1 and phenomenon 2 mainly due to the following:
1, ground induced light does not have radio transmission-receiving function；2, the induction of ground only show a kind of lamp color (it is red,
Yellow or other colors), it cannot show two kinds of lamp colors (for distinguishing lane)；3, it can not judge vehicle driving at which
The device in lane is only through a pair of of infrared transceiver device at present to judge whether a section has vehicle to pass through；4, existing
Which lanes coil car test/microwave car test/ultrasonic wave car test be able to solve vehicle the problem of, but site operation trouble
Also unrealistic (generally every 15 meters or so installation set of device).Coil car test ground fluting, microwave car test will install drive test again
On high bar, ultrasonic wave workshop will be mounted on the portal frame above each lane.
