With the quickening of Transportation Infrastructure Construction process, due to reorganization and expansion, maintenance activity and the road construction area generated
It is more and more.The appearance in road construction area significantly reduces road passage capability, and driver is as most living in traffic system
Jump most uncontrollable factor again, in the driving environment complicated in this way of construction area its behavior easily generate larger fluctuation, once not
Corresponding driving measure can be taken in time, it is more likely that cause serious traffic accident.Therefore, construction area is reduced to cause driver
Harmful effect, improving vehicle operational efficiency becomes one of urgent problem to be solved.
Currently, construction area generally prompts driver by the way that the method for trackside static mark is arranged, while can profit
It is assisted with flashing index, changeable-message sign etc..But under different traffic behaviors, driver's converges behavior table
Now and differ.When the magnitude of traffic flow is smaller, the behavior of driver is relatively free, how driver to be allowed smoothly to be converged with present speed
The problem of conjunction is control of traffic and road department overriding concern；And the magnitude of traffic flow it is excessive when, driver slow down too early so that stop come
Searching suitably converges gap, can cause the delay of waste and the traffic of path resource, how guide driver suitable at this time
Position converge, be top priority.
Invention content
Multistage early warning can be provided to driver according to different traffics the purpose of the present invention is to provide a kind of, be

The time of alert module publication three-level early warning, TReactionThe reaction after the pre-warning signal that Vehicle Controller is sent out is received for driver to determine
The plan time.According to the previous investigation and experience of engineers and technicians, in the present embodiment, T can be setLane-change=6s, TEarly warning=4s,
TReactionAfter hearing three-level early warning, carrying out corresponding driver behavior can be at by=3s, three-level early warning position at this time namely driver
Work(lane-change and the extreme position for not hitting construction area related facility.
If S4, vehicle are in track where construction area, central controller message processing module compares vehicle location in real time
(XVehicle) and early warning position (X1、X2、X3), judge whether to need to issue warning information；
Work as XVehicle=X1When, level-one early warning is issued, warning information is：" men working area, before hearing next voice prompt
It please keep keeping straight on "；Work as XVehicle=X2When, two level early warning is issued, warning information is：" men working area, it is noted that converge "；Work as XVehicle≤
X3And VVehicleWhen ≠ 0, three-level early warning is issued, warning information is：" excessively close away from men working area, please to wait for parking ".
S5, warning information is if desired issued, then central controller is sent to Vehicle Controller by signal projector, there is vehicle
After set controller receives, warning information is issued by warning module.
In conclusion the present invention is by acquiring construction section information of vehicle flowrate, according to each vehicle location and speed, in conjunction with
Construction location determines level-one early warning position and two level early warning position, then is combined by level-one early warning position and two level early warning position
Car speed calculates three-level early warning position, and vehicle is combined according to level-one early warning position, two level early warning position, three-level early warning position
Real time position judges whether to send warning information, by Vehicle Controller reception warning information, to be provided reliably for driver
Driving strategy, avoid the generation of construction section traffic jam, improve traffic route utilization rate and traffic efficiency, ensure that
The safety of road construction.
