Description
Technical field
The present invention relates to traffic information technical fields, and in particular to one kind carrying out road congestion prediction based on automobile data recorder
Method and apparatus.
Background technology
Automobile data recorder i.e. record vehicle travels the instrument of the relevent informations such as image and sound on the way.Driving recording is installed
After instrument, it is able to record the video image and sound of running car overall process, evidence can be provided for traffic accident.Like self-driving travel
People can also record the process for conquering difficulties and dangers with it.It is recorded a video when driving when walking, while time, speed, institute is in place
It sets and is all recorded in video recording, suitable black box.Also it can be in and shoot the joy of life as DV, or make as household monitoring
With.Parking monitoring can also be usually done, automobile data recorder is installed, video data cannot be cut, if cut, in liability accident
Help can not be then provided after generation.Also for preventing those social inevitable blackmail behaviors now.
Different automobile data recorder products has different appearances, but it organizes Chengdu and has substantially：(1) host：Including microprocessor
Device, data storage, real-time clock, display, camera lens module, operation key, printer, data communication such as connect at the devices.If
Do not include display, printer in host main body, then should show and print out interface there are corresponding data.(2) speed passes
Sensor.(3) Data Analysis Software.
With the raising of people's living standard, the more private car owning rate the more artificial in ascendant trend year by year
Facilitate trip and has purchased automobile.Vehicle drastically increases, corresponding to be more and more crowded road and be blocked on road
More and more intensive automobile.Due to various reasons, China loses about 170,000,000,000 yuan for 1 year caused by traffic congestion, and year by year on
It rises.If the road conditions of urban road can be monitored, it can take appropriate measures when congestion occurs in road, to avoid
There is the phenomenon that long-term congestion in road, to a certain extent the case where alleviation road traffic congestion.It mainly monitors in the following way at present
The road conditions of urban road：By being adopted using tools such as map coil, velocity radar and the cameras that tests the speed on the major trunk roads in city
Collect the road conditions such as occupancy, vehicle flowrate and the speed of road.However, although said program can realize the road conditions to major urban arterial highway
Monitoring then needs the tools such as resettlement figure line circle, velocity radar and the camera that tests the speed on each major trunk roads in city, scheme real
It is higher to apply cost.
Patent No. 201180031766.0 discloses a kind of congestion prediction device, including：Speed detecting mechanism, detection
Come from the speed of vehicle and exports testing result；Vehicle headway testing agency, detection it is described from vehicle and other vehicles it
Between vehicle headway and testing result is exported；Related operation mechanism, according to the testing result of the speed and the workshop
The testing result of distance carries out it related operation (related coefficient both to obtain), and operation result is exported；It is stifled
Vehicle projecting body predicts the generation of traffic congestion according to the operation result of the related operation.
The vehicle headway of foregoing invention monitors to obtain by radar installations, and detailed process is：Pip test section 31
Go out to reflect the position of the pip of signal from radar installations 12 according to the signal detection exported, and testing result is exported.Other
Vehicle detection portion 32 is for example, according to the testing result from the position to pip that pip test section 31 exports, and according to phase
Distribution of the distance between the adjacent pip with multiple pips, detects to be present in other vehicles from vehicle periphery,
And testing result is exported.Wherein, the quantity of other vehicles of detection is at least at 1 or more.Vehicle headway test section 33 for example,
According to the testing result (at least 1 or more other vehicles) of other vehicles exported from other vehicle detection portions 32, detect
From the distance between vehicle and other vehicles (vehicle headway), and by testing result and the quantity (platform of other vehicles detected
Number) it exports together.Operational part 34, according to the testing result to the speed (speed) from vehicle exported from vehicle speed sensor 11 with
And exported from vehicle headway test section 33 to the testing result from the distance between vehicle and other vehicles, calculate, with
The relevant quantity of state of possibility to block up from front of the traveling of vehicle, and the output of (operation) result will be calculated.
The inventors discovered that the speed detecting mechanism and vehicle headway mechanism for monitoring and related operation mechanism of foregoing invention
It is all different equipment, volume of transmitted data is big, and data processing amount is also big, of high cost, and server burden is big.
Inventors have discovered that between the stabilization transport condition not blocked and blocking generating state, it is assumed that when workshop
Between=speed/vehicle headway, when the value bit of inter-vehicular time and vehicle headway is within the scope of some, vehicle is to be in not block up
The stabilization transport condition of plug, when inter-vehicular time and vehicle headway are in another within the scope of some, then vehicle is to be in blocking
State.
