Description

Obtain the method and system of traffic information
Technical field
Embodiment of the disclosure is related to the method and system for obtaining traffic information, and relates more specifically to a kind of based on figure The method and system of the acquisition traffic information of picture and/or video.
Background technology
The primary technology of urban traffic situation digging system is, by obtaining transport information and carrying out data mining, therefrom to extract and hand over Logical status information, carries out data fusion to realize to traffic state information.Under normal circumstances, it is necessary to periodically gathered data, And data are handled, by the correlation technique of data mining, urban history and current road conditions are obtained, and then lure by traffic The mode such as lead, mitigate and prevent traffic congestion, and finally realize reasonable distribution of the traffic flow on each section of road network, improve city City's traffic efficiency.
The main source of current traffic information data has three classes:Physical sensors, Floating Car and video detector.Pass through thing The equipment of reason sensor gathered data includes:Coil checker, supersonic detector, infrared detector etc..These sensors are more For fixed sensor, the vehicle pass-through situation in a certain fixed position or region is gathered.Floating Car refers to be provided with positioning and nothing The common vehicle of line communicator, this vehicle can enter row information with traffic information center and exchange.When Floating Car is on road During traveling, the information such as latitude and longitude coordinates, instantaneous velocity, direction, the turn around time of vehicle can be reported immediately.Video detector is Fixing point detection device, by carrying out graphical analysis to collection traffic image, the traffic parameter in multiple tracks can be detected simultaneously.
After the data for collecting above-mentioned separate sources, by technological means such as data fusion, big data analyses, it can calculate Show that vehicle flowrate, average speed, time headway, time occupancy, space occupancy, traffic density of each bar road in city etc. are believed Breath, classification is made to the traffic behavior of each bar road.Traffic can be typically divided into:Unimpeded, jogging, congestion and seriously gather around Stifled four classes.Finally, by modes such as broadcast, web page display, current traffic condition can be presented to user, and pass through navigation Guiding is made to vehicle etc. mode, so as to realize the effect for avoiding congestion, improving operational efficiency.
Chinese patent application the 200710043538.0th discloses a kind of visual intelligent traffic control system and in fact Existing method, it is included:Electronic license plate, remote vehicle identifying device, data storage device and communication interface arrangement.The long distance It is arranged on incessantly on road from vehicle identifier, the number will be stored in after the information of vehicles identification in vehicle electric car plate It is connected according to storage device, and with communication interface arrangement communication, urban transportation command centre is uploaded in real time, vehicle is carried out Be remotely located track, remotely test the speed, dredging automatically under each section vehicle flowrate and busy state.
Chinese patent application the 03134351.1st is related to a kind of mechanical transport management method based on GPS technology, the party The geography information that method is sent to the unit that wireless transmission is received is encoded, then geographical the believing to wireless transmission receiving unit reception Breath is decoded.Coded system is the geographical position of confirmed other vehicle codes as coding using the license number of a certain vehicle Confidence breath could be by reception processing, and display distance information.This mechanical transport management method based on GPS technology, Ke Yishi The distance and distance change of the fore-aft vehicle travelled on highway are now understood at any time, while not affected by environment.
By physical sensors or video detection technology collection traffic data, it is necessary to each bar road, intersection in city Mouth etc. is unified to install physics, video sensor.Therefore there is cost of installation and maintenance height, coverage is small, be only capable of detection fixation The shortcomings of data of position.By the restriction of the factors such as manpower, fund, this fixed sensor is difficult to obtain large-scale promotion.
Floating car technology can collect the running status of vehicle in real time, be currently that most commonly used transport information is adopted Diversity method.But in actual applications, traffic is influenceed by many factors such as vehicle flowrate, time headway, traffic densities, And this method can only collect the data such as the coordinate of single car, speed, it is difficult to which the overall condition to road makes assessment.And by In need to install particular acquisition vehicle coordinate, speed equipment (such as GPS device), under conditions of installation is limited, it is difficult to In real time, condition of road surface is accurately provided.Moreover, the travel speed of vehicle is influenceed larger by the signal facility such as traffic lights, it is single Speed data can not reflect the lights state of vehicle front.For the vehicle run at a low speed, it is difficult to which differentiation is by red light Or congestion causes.Therefore, it is relatively low for the classification accuracy of congestion in road state.
