Embodiment
As shown in Figure 1, the implementation step based on the road conditions management method of running information in the embodiment of the invention is as follows:
1) gather to meet with the road conditions vehicle geographic position, speed, acceleration and with the spacing of front truck;
2) be sent to road conditions administrative center with the geographic position of gathering, speed, acceleration with the spacing of the front truck back of packing by wireless network;
3) road conditions administrative center obtains the semantization map location of vehicle according to the geographic position that receives, and obtains the traffic jam situation of current semantization map location according to the speed that receives, acceleration with the spacing of front truck.
Meet with road conditions and be meant the accidents relevant such as vehicle encounters traffic congestion, traffic hazard, traffic control, pavement behavior with the vehicle ' traffic information.
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 a highway, then on electronic chart, search the nearest outlet or the position, refuelling station of this section highway, with the semantization map location of this nearest exit position as current geographic position; Otherwise, then on electronic chart, search from the nearest point of interest of current geographic position, 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,, can more conveniently obtain the traffic jam state intuitively, the traffic jam inquiry service can be provided more quickly and accurately by obtaining of semantization map location.
All define a point of interest in the zone in the electronic chart by title, sight spot for example, the shop, hotel or the like by with the semantization map location of this point of interest as current geographic position, can realize the location to the semantization map location apace.Because the famous degree difference of different point of interest definition, therefore when on electronic chart, searching the nearest point of interest of current geographic position, take all factors into consideration the famous degree of point of interest and near the higher point of interest of popularity two selection of parameter of distance of point of interest as the semantization map location.
Original geographic position Location is expressed as on the electronic chart:
Location=(Object,Name+Namespace,Properties)
Wherein, Object is a 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.
When vehicle during in other positions, Name is near the title of the point of interest the original GPS positional information, and for example the semantization map location that obtains in the city of Hangzhou position is " apart from 100 meters of bridge cut-off ", and wherein Name is the point of interest bridge cut-off, and Distance is 100 meters.Because different point of interest interest rank differences, the mode of specifically choosing which point of interest be according to merchant's maximum of the famous degree of point of interest and two parameters of distance and position choose neighbouring and point of interest that popularity is higher as L_result POI.Be better than as " apart from 100 meters of bridge cut-off " " apart from 100 meters of crossings, Shi Han road, Beishan Mountain road ", then final semantization map location is " apart from 100 meters of bridge cut-off ".Select the expression formula of point of interest as follows according to famous degree of point of interest and distance and position:
L result = ( roadexit | | gasstation , Dis tan ce ) ( Location = highway ) ( L result POI , Dis tan ce ) ( Location = city )
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 pairing semantization map location generation traffic jam of this vehicle.In addition, at first be provided with 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 pairing 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 a 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 the 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.
Suppose P I-2 (x I-2, y I-2)And P I-1 (x I-1, y I-1)For two points of signal, P are arranged before the hop signal I (x i, y I)Be the estimated value of signal hop, v iBe the average velocity of vehicle current driving, t is P I-1And P iInterval time.Estimated value according to the method signal hop of linear interpolation compensation data is as follows,
x i = x i - 1 + v i * t * x i - 1 - x i - 2 ( x i - 1 - x i - 2 ) 2 + ( y i - 1 - y i - 2 ) 2
y i = y i - 1 + v i * t * y i - 1 - y i - 2 ( x i - 1 - x i - 2 ) 2 + ( y i - 1 - y i - 2 ) 2
In the present embodiment, the filter velocity threshold setting is 200km/h, if certain a bit surpasses 200km/h with last 2 average velocitys, can infer obviously that then the geographic position that obtains makes a mistake, thereby the geographic position filtration of hop will take place.
Gather artificial report voice and live video in the step 1) in the lump with event type information; Step 2) will manually report the packing of voice and live video in the lump and be sent to road conditions administrative center; In the step 3), define event type rank α at first respectively, positional information rank β, the rule list of time rank γ and weather rank δ, manually report voice and obtain event type rank α by speech recognition then according to rule list, set road conditions according to the different event type and report the report object, obtain positional information rank β according to vehicle current geographic position type and rule list, according to current time and rule list acquisition time rank γ, weather and rule list according to current region obtain weather rank δ, (road conditions in this geographic position of alpha+beta+γ+δ)/4 calculate are reported significance level Rank, and the size of reporting significance level Rank according to road conditions is reported the pairing report object of type to road conditions successively and sent road conditions and report information according to Rank=then.In the present embodiment, event type rank α, positional information rank β, time rank γ and weather rank δ be greater than 0 less than 1, road conditions report significance level Rank also greater than 0 less than 1.Report significance level Rank by road conditions, can realize significance level classification to different road conditions reports, realize the priority processing of significant problem, and can report the pairing report object transmission of type road conditions to road conditions according to the road conditions type and report information, thereby can notify traffic, hospital, road maintenance department and same fleet the very first time, thereby can respond rapidly, solve the road conditions problem.
