Meet with road conditions and refer to vehicle encounters traffic congestion, traffic hazard, traffic control, pavement behavior etc. and the vehicle relevant accident of traffic information of travelling.
When road conditions administrative center obtains the semantization map location of vehicle according to the geographic position that receives, obtain the current geographic position type of vehicle according to the geographic position, if current geographic position is highway, then search nearest outlet or the position, refuelling station of this section highway at electronic chart, with the semantization map location of this nearest exit position as current geographic position; Otherwise, then search from the nearest point of interest of current geographic position at electronic chart, and with the semantization map location of this point of interest as current geographic position.Obtain the semantization map location according to geographical location type, by obtaining of semantization map location, can more conveniently obtain the traffic jam state intuitively, the traffic jam inquiry service can be provided more quickly and accurately.
All define a point of interest in the zone by title in the electronic chart, sight spot for example, the shop, hotel etc. by with the semantization map location of this point of interest as current geographic position, can realize the location to the semantization map location rapidly.Because the famous degree difference of different point of interest definition, therefore when electronic chart is searched the nearest point of interest of current geographic position, take all factors into consideration the famous degree of point of interest and choose near the higher point of interest of popularity as the semantization map location to two parameters of distance of point of interest.
Original geographic position Location is expressed as on the electronic chart:
Location=(Object，Name+Namespace，Properties)
Wherein, Object is position coordinates, Name is the textual description of position, because same Name position may have repetition, as " liberation road " arranged in different cities, need to adopt namespace to limit unique proper geographic position, Properties is the set of a series of attributes in position itself and attribute, as famous degree importance etc.
Semantization map location L_result is expressed as:
L_result=(Name,Distance)
Wherein, Name represents the title of semantization map location, and Distance represents the distance of this point of interest.
For example work as the vehicle semantization map location that the somewhere obtains on highway and be " apart from Hang Jin thoroughfare high speed Hangzhou outlet 1km ", wherein Name is the outlet of Hang Jin thoroughfare high speed Hangzhou, and Distance is 1km.

L
resultPOI＝max(importance/Distance)
When obtaining the traffic jam situation in the step 3), the obstruction threshold speed at first is set, obtain the initial geographic position of the transmission of same car in the fixed time then and finish the geographic position, obtain initial geographic position and finish between the geographic position distance and should be in the fixed time average overall travel speed of vehicle, if this average overall travel speed is lower than the obstruction threshold speed, then judge the end geographic position corresponding semantization map location generation traffic jam of this vehicle.In addition, at first arrange in the step 3) in the present embodiment and stop up the spacing threshold value and stop up acceleration rate threshold, if the current spacing with front truck of a certain vehicle is less than stopping up the spacing threshold value, and acceleration is lower than the obstruction acceleration rate threshold, then judges the corresponding semantization map location of the current geographic position generation traffic jam of this vehicle.Present embodiment is realized blocking up detecting by above-mentioned two kinds of methods and is judged, can submit the accuracy of detection to.Present embodiment is realized blocking up detecting by above-mentioned two kinds of methods and is judged that the method for obtaining the traffic jam situation can adopt following formula to represent:
State＝（（t≥T)&&（（v＜V)||s＜S&&a＜A))
That is, if T historical time car average velocity v is less than threshold speed V, or car and leading vehicle distance s less than spacing threshold value S and acceleration a less than acceleration rate threshold A, judge that current situation is traffic jam.
Generally speaking, meeting has high building to stop and other disturb under the bigger situation, comprises that hop appears in the geographic location signal of GPS easily.The default filter velocity threshold value of road conditions administrative center in the step 3), if hop appears in the geographic location signal that receives, then at first obtain geographic position and the interval time of taking place before and after the hop twice, calculate then the average speed value of hop in interval time takes place, if filter in the geographic position that average speed value above default filter velocity threshold value, then will take place after the hop; If average speed value surpasses default filter velocity threshold value, then adopt the method for linear interpolation compensation data to obtain its geographic position to the geographic position between the geographic position that obtains for twice; If do not receive geographic location signal in the fixed time, then obtain current geographic position by the method for linear interpolation compensation data.By filtration, linear interpolation compensation data, can effectively improve the availability of geographic location signal, for traffic jam provides more rationally, accurate localization information.
