Description
Technical field
The present invention relates to expressway safety technical fields more particularly to a kind of expressway traffic accident to monitor reminding method.
Background technology
Nowadays motor vehicles are more and more, and traffic accident probability is also increasing.Especially on a highway,
Serious block up occurs since the bad weather of the low visibilities such as various climatic issues such as dense fog, severe snow, heavy rain causes highway
Vehicle, car accident, the event for the major traffic accidents such as even shunt into one another occur again and again, in case of not having after traffic accident
Timely processing often causes danger to later vehicle.
Highway is often by the way of video monitoring, by manually checking prison for the monitoring of peril at present
Control video or the phone that receives the report for police service learn, this for the processing of peril and not in time, especially peril not
It is very big to later vehicle risk during processing, the easy generation for just causing second accident.Therefore, expressway traffic accident prison is realized
Visualization, systematization and the intelligence of survey are the important measures for improving freeway management level.
Invention content
The technical problem to be solved by the present invention is to：The present invention is directed to the limitation and deficiency of the prior art, provides a kind of high speed

With the second section third runway X23For, average overall travel speed V23=113km/h is in the section and the driving
Road vehicle maximum travel speed threshold value V23·MAX=the 120km/h and minimum traveling threshold speed V of vehicle23·MIN=110km/h it
Between, therefore think section runway X23Zero defects occurs, and belongs to normal reach.
Step2.2：If certain section runwayVehicle average overall travel speedIt is higher than
The vehicle maximum travel speed threshold value of corresponding runwayBoth formula (2) requirement had been met, then it is assumed that the section runwayThere is the possibility having an accident, belongs to section to be endangered, it will be in the first two section of the section, i.e. Xa-1And Xa-2Section prompts
Alarm to be endangered is shown in screen, to remind back car；The road section information is sent to traffic control department simultaneously；
Specifically：
With the first runway of third section X31For, average overall travel speed V31=124km/h is in the section and the driving
Road vehicle maximum travel speed threshold value V23·MAXOn=120km/h, therefore think section runway X31Belong to section to be endangered, it will
In the first two section of the section, i.e. X2And X1Alarm to be endangered is shown in section prompting screen, to remind back car；It simultaneously should
Road section information is sent to traffic control department.
Step2.3：If certain section runwayVehicle average overall travel speedLess than pair
Answer the minimum traveling threshold speed of the vehicle of runwayBoth formula (3) requirement had been met, then it is assumed that the section runwayHave peril, belongs to dangerous section, it will be in first three section of the section, i.e. Xa-1、Xa-2And Xa-3Section prompts
Hydropac is shown in screen, to remind back car；The road section information is sent to traffic control department simultaneously.
Specifically：
With the 4th the second runway of section X42For, average overall travel speed V42=74km/h is in the section and the driving
The minimum traveling threshold speed V of road vehicle42·MINUnder=90km/h, therefore think section runway X42Belong to dangerous section, it will
In first three section of the section, i.e. X3、X2And X1Alarm to be endangered is shown in section prompting screen, to remind back car；Simultaneously will
The road section information is sent to traffic control department.
Embodiment 2：The present invention uses section driveway partition method and video-based vehicle detection velocimetry, in conjunction with vehicle average row
The magnitude relationship of speed and the minimum traveling threshold speed of vehicle maximum travel speed threshold value, vehicle is sailed to traffic accidents
Generation carry out intelligent monitoring and prompt, if monitoring to have section endanger or danger section, in the preamble area of the section
Warning information is shown in section prompting screen, and to remind back car, the road section information is also sent to traffic control department with right in addition to this
Peril is handled.Compared with prior art, the present invention realizes visualization, the systematization monitored to expressway traffic accident
And intelligence, it can fundamentally improve the management level of highway.
Embodiment described above only indicates embodiments of the present invention, the description thereof is more specific and detailed, but can not manage
Solution is limitation of the scope of the invention.It should be pointed out that for those of ordinary skill in the art, not departing from this hair
Under the premise of bright design, several variations and modifications can also be made, these belong to the scope of the present invention.
