Description
Technical field
The present invention relates to traffic information technical fields, and in particular to a kind of to carry out road congestion prediction using automobile data recorder
Method and apparatus.
Background technology
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
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.
Application No. is 201410256474.2 patents to disclose a kind of real-time road monitoring method and real-time road monitoring
Equipment, a kind of real-time road monitoring method, including：The driving note of vehicle where obtaining the car-mounted terminal of car-mounted terminal feedback
Record information；According to the driving recording information of the vehicle, the current traffic information of the vehicle is determined and recorded, wherein described
The current traffic information of vehicle includes：The current direction of traffic of section that the vehicle is presently in, the vehicle and described
The current running speed of vehicle；If the current running speed of the vehicle is less than predetermined threshold value, it is N number of full to judge whether that record has
The traffic information of other vehicles of sufficient condition, wherein the N is greater than or equal to 1；If record has N number of other vehicles for meeting condition
Traffic information, then judge that the section that the vehicle is presently in is in congestion status；Wherein, described to meet the other of condition
The traffic information of vehicle is specially：The time point at the record time point and the driving recording information for obtaining the vehicle of traffic information
The vehicle for being spaced in predetermined threshold value, and being recorded in traffic information residing for section and direction of traffic and the car-mounted terminal institute
It is identical in vehicle, and the running speed recorded in traffic information is less than the predetermined threshold value.The judgement current institute of vehicle
The section at place is in congestion status, further includes later：All mobile terminals into monitoring range send reminder message, described to carry
Awake message indicates that the section that vehicle where the car-mounted terminal is presently in is in congestion status.The judgement vehicle is current
Residing section is in congestion status, further includes later：To in the preset range in the section that the vehicle is presently in
Mobile terminal sends reminder message, and the reminder message indicates that the section that vehicle where the car-mounted terminal is presently in is in and gathers around
Stifled state.
The inventors discovered that foregoing invention require by the connector of golo equipment be inserted into vehicle onboard diagnostic system (OBD,
On-Board Diagnostic) interface, to realize the connection of the OBD of golo equipment and vehicle, when golo equipment and vehicle
After OBD connections, golo equipment can capture in real time by vehicle OBD interfaces submitting signal (signal include vehicle driving note
Record information), golo equipment captures carry out data dissection process after signal after feed back to above-mentioned server.But above-mentioned road conditions
Monitoring method needs mobile unit (golo) to upload mass data to server process, the processing of server by wireless network
It bears bigger.
