Embodiment
In intelligent transportation field, certain density is reached (such as bayonet socket deployment：Vehicle in normal driving process,
A bayonet socket is necessarily passed within 10 minutes) city, based on each prolonged bayonet socket of car in the city cross car record, warp
Statistical analysis is crossed, the driving trace rule of vehicle is formed.By vehicle driving trace rule model, the space-time for obtaining each car is lived
Dynamic rule, main driving trace, so as to further analyze residential location, occupational characteristic, the outdoor activity rule of car owner,
Studied and judged eventually for suspicious and high-risk vehicle.Such as：Normal private car, should from the point of view of long-term driving trace rule
There is obvious feature in this.For normal private car on and off duty, morning, afternoon on weekdays, residence and workplace
Between driving trace more fix.And the driving trace such as weekend, the friend-making of festivals or holidays, trip is relatively fewer.From this kind of vehicle
Long-term trajectory diagram from the point of view of, it should show obvious trunk track, less bifurcated track.Meanwhile, above-mentioned vehicle at dead of night,
The driving trace of the particular times such as morning, it should relatively fewer.
And the vehicle of illegal activity is engaged in, it can run helter-skelter mostly, (taxi, logistics fortune are excluded without obvious normal trace
The vehicle of particular job property such as defeated car).From the point of view of the long-term trajectory diagram of this kind of vehicle, whole track is relatively random.Meanwhile, this
Class vehicle at dead of night, the driving trace of the particular time such as morning, it is relatively many.Vehicle with above-mentioned driving trace rule, just
It is suspicious and high-risk vehicle.
How the bayonet socket in database crosses car record, and it is to be worth a problem of research to form vehicle driving trace.
How same vehicle by tracking clustering extracts trunk track (total degree that the track is travelled, total a plurality of track of many days
Time is generally up to about) it is also a problem for needing to consider.
The solution of above-mentioned two problems is, it is necessary to overcome following difficulty：
Simple dependence bayonet socket crosses car and records to form vehicle driving trace, relatively difficult when judging whether vehicle stops, i.e.,
It is difficult to judge whether a driving trace has terminated.
There is certain defect in existing bayonet vehicle identification intelligent algorithm, be stained, blocked by illumination, car plate etc. it is a variety of it is objective because
, there is Car license recognition mistake, cross that car identification is omitted, bayonet socket crosses the more problem such as clap car more, have a strong impact on track of vehicle in element influence
The accuracy of generation.Due to the influence of these problems, when polymerizeing to the same vehicle a plurality of driving trace of many days, if
The pattern matched according to the point of bayonet socket one by one, causes path matching to fail greater probability, ultimately causes the aggregate rate of track
It is too low.
In view of the above-mentioned problems, the present invention proposes a kind of track of vehicle generation method and the track for the generation is carried out
The method of tracking clustering.Described in detail below by way of specific embodiment.
It please join Fig. 1, Fig. 1 gives the flow chart of track of vehicle generation method.
S11, the bayonet socket for inquiring about from database the beginning and ending time section vehicle license plate cross car record, and suitable according to time order and function
Record is ranked up described in ordered pair；Car record is crossed using first record after sequence as current.
Magnanimity bayonet socket is saved in database crosses car record data, is made a slip of the tongue car record extraction carrying out a certain vehicle card
When, it is thus necessary to determine that spend the beginning and ending time of car record.The beginning and ending time is generally also the cycle time to form one track of a car.
Such as, it is necessary to when analyzing the car driving trace of one day, generally can using 24 hours as one analytical cycle, than
Such as same day 6:00 AM to 6 points of beginning and ending times as Track Pick-up of the next morning.For example, inquiry car plate is in database
Zhejiang A12345 vehicle is lighted the car of crossing stopped to 6 points of May 21 day in 2014 from 20 days 6 May in 2014 and recorded；Assuming that inquire
Crossing car record has 10, and these, which cross car record, needs to be ranked up according to the priority for spending the car time, and table 1 is to cross car note after sorting
Record.
Table 1
Next need for the generation that car record carries out track of crossing after sequence.With Zhejiang A12345 this car 2014 5
On the moon 20 8:05 crosses car record by bayonet socket 121 as current, starts the generation of track.
S12, calculate it is current cross car record and its next cross car record time difference.
For above-mentioned example, that is, vehicle Zhejiang A12345 is calculated by bayonet socket 121 and by the time difference of bayonet socket 122；According to
Upper table, the time difference is：540 seconds (20 days 8 Mays in 2014:05 and 2014 on May 20,8:14 time interval).
S13, inquiry be current to cross car record and its next is crossed car and record being averaged the car time between corresponding two bayonet sockets.
Before the track of vehicle for carrying out proposition of the embodiment of the present invention extracts flow, bayonet socket mistake that can be in database
Car is recorded, and realizes the statistics to the car time that was averaged of city any two bayonet socket, and a bayonet socket is formed in database and is averaged
Cross car timetable.The example that the average time crosses car table is as follows：
| ID | Bayonet socket is encoded | Bayonet socket is encoded | It was averaged the car time (in seconds) |
| 1 | 121 | 122 | 600 |
| 2 | 122 | 123 | 700 |
| 3 | 123 | 124 | 600 |
Table 2
Two bayonet sockets for not being direct neighbor, also can averagely be crossed in bayonet socket in car timetable increases respective record, this
The car time that was averaged between two bayonet sockets is the car time sum that was averaged of all direct neighbor bayonet sockets.
There is the statistics of the car time that was averaged of city any two bayonet socket, to inquire about and currently cross car record and its next
It is exactly lead-pipe cinch feelings to spend the car time that was averaged that car recorded between corresponding two bayonet sockets.
Or with above-mentioned example illustrate, inquire about obtain it is current cross car record and its next cross car record corresponding two
The car time that was averaged between bayonet socket is 600 second.
It should be noted that there is no sequencing between above-mentioned steps S12 and S13.
S14, the duration travelled according to the time difference, be averaged car time and the termination of default vehicle judge car
Traveling whether is terminated between described two bayonet sockets, if it is, turning S15, otherwise, turn S16.
S15, using it is current cross car record corresponding bayonet socket as the tail bayonet socket of the track of vehicle.
S16, using it is current cross car record corresponding bayonet socket as a non-tail bayonet socket in track of vehicle；Will be current next
Bar crosses car record as current and crosses car record, returns and performs S12, and until all records, all processing is completed.
Step S14 according to obtained in abovementioned steps " it is current cross car record and its next cross car record time difference " and
" current cross car record and its next is crossed car and record be averaged the car time between corresponding two bayonet sockets ", and combine " default
Vehicle terminates the duration of traveling " judge whether vehicle terminates traveling between two bayonet sockets.Judge vehicle is between two bayonet sockets
The no traveling that terminates is intended to judge whether the terminal for reaching track.The temporary parking of vehicle in the process of moving is not construed as car
Terminate traveling.So " default vehicle terminates the duration of traveling " could be arranged to 10 minutes according to common experience, or
For more time.
Specifically when whether progress vehicle terminates the judgement of traveling between two bayonet sockets, it can operate as follows：
Judge whether " current to cross car record and its next time difference for crossing car record " is less than the duration that default vehicle terminates traveling,
If it is, confirming that vehicle is in transport condition, traveling is not terminated；Otherwise, further according to " current car of crossing records next with its
It's the time difference of car record pasts bar " and it is " current to cross car record and its next mistake car records being averaged between corresponding two bayonet sockets
Spend the car time " judge whether vehicle terminates traveling between described two bayonet sockets.
When being determined whether according to time difference and the car time that was averaged, the side in following examples can be used
Method：
If two bayonet sockets were averaged the car time within 15 minutes, and two time differences for crossing cars record are less than 2 times
It was averaged the car time, then judges that vehicle is in transport condition, and otherwise judged that vehicle is in and terminate transport condition.
If two bayonet sockets averagely spend the car time within 15 minutes to 45 minutes, and two time differences for crossing car record are small
In 1.5 times of average times, then judge that vehicle is in transport condition, otherwise judge that vehicle is in and terminate transport condition.
If two bayonet sockets averagely spent the car time more than 45 minutes, and two time differences for crossing car record are less than average time
Plus the sum of 20 minutes, then judge that vehicle is in transport condition, otherwise judge that vehicle is in termination transport condition.
When judge vehicle it is current cross car record corresponding bayonet socket with it is current cross car record next cross car record it is corresponding
Bayonet socket between when terminating traveling, current car of crossing is recorded into corresponding bayonet socket as the tail bayonet socket of the track of vehicle, otherwise will be current
Cross car and record corresponding bayonet socket as a non-tail bayonet socket in track of vehicle, and continue to cross car record as currently using next
Cross car record, return and perform step S12 and start new round processing, cross car record until all processing is completed.
In above-mentioned example, vehicle Zhejiang A12345 is 540 seconds by bayonet socket 121 and by the time difference of bayonet socket 122；Bayonet socket
The car time that was averaged between 121 and bayonet socket 122 is 600 second；Default vehicle terminate traveling when a length of 600 seconds.So according to
Above-mentioned judges whether vehicle terminates the method citing of traveling, it can be deduced that the vehicle is not whole between bayonet socket 121 and bayonet socket 122
Only travel, so bayonet socket 121 is a bayonet socket in the track of vehicle, " the bayonet socket list that track is passed through can be recorded in
In ".Then, car record, i.e., 2014 on May 20,8 are crossed by next of the vehicle:14 cross car note by this of bayonet socket 122
Record and cross car record as current, restart to perform step S12~S16.This is crossed car and records last implementing result：Bayonet socket
122 be a middle bayonet socket (non-tail bayonet socket) in the track of vehicle, is recorded in vehicle " bayonet socket row that track is passed through
In table ".The bayonet socket 123,124 crossed in car record is equally judged as the middle bayonet socket of the track of vehicle, is recorded in its " rail
In the bayonet socket list that mark passes through ".
For the vehicle 20 days 8 May in 2014:39 perform step S12~S16 by the car record of crossing of bayonet socket 125：Should
Car record is crossed as current and crosses car record, car is crossed for next and is recorded as " 20 days 18 May in 2014:03 passes through bayonet socket 258 "；Meter
The current car record of crossing of calculation spends the time difference for spending the car time that car is recorded with its next, is as a result 24 minutes 9 hours；Inquiry is current
Cross car and record corresponding bayonet socket and next and cross car and record be averaged the car time between corresponding bayonet socket, it is assumed that inquire about obtained card
The car time that was averaged between mouth 125 and bayonet socket 258 is 900 second；Default vehicle terminate traveling when a length of 600 seconds.According to
Judge whether vehicle terminates the method citing of traveling described by step 14, it can be deduced that the vehicle is in bayonet socket 125 and bayonet socket 258
Between terminate traveling, so bayonet socket 125 is the tail bayonet socket of the track of vehicle, be recorded in " track pass through bayonet socket list "
In.So far the driving trace generation of the vehicle is finished.Table 3 gives the example of one " the bayonet socket list that track is passed through ".
| Vehicle license plate | Track sequence number | Numbered by bayonet socket | By bayonet socket sum | Total travel duration |
| Zhejiang A12345 | 1 | 121->122->123->124->125 | 5 | 34 minutes |
Table 3
Cars record, another track of generation that can be same are crossed for the other of the vehicle in table 1, and is added to
In " the bayonet socket list that track is passed through ", table 4 please be join.
Table 4
The bayonet socket that the track of vehicle not only recorded in table 4 passes through, is also recorded for by the total of bayonet socket and passes through this
The total travel duration of a little bayonet sockets.
Explanation is needed exist for, car record is crossed for the last item of the vehicle in table 1, when as current
When crossing the car record above-mentioned Track Pick-up step of execution, it does not have corresponding next to cross car record, can now suspend and handle this
Cross car record.When the car of crossing for extracting next beginning and ending time section vehicle is recorded, when proceeding by new round trajectory extraction, by this
The car record of crossing of pause processing crosses car record as the current of new round trajectory extraction, the first mistake of next beginning and ending time section
Car record crosses car record as its next and performs above-mentioned steps S12~step S16.If final implementing result is the pause
The car of crossing of processing records corresponding bayonet socket for tail bayonet socket, then is added to track unfinished before and passes through in bayonet socket list.
The last item directly can be crossed car and record corresponding bayonet socket as tail bayonet socket by a kind of certain more simple treating method.
In above-described embodiment flow, the situation for judging vehicle abnormality can be increased.Such as, if step S12 is calculated
The time difference gone out is more much smaller than the car time that was averaged that step S13 inquiries are obtained, then there will be likely some deck.Now, exit
Track Pick-up flow.In another example, if continuous two after sequence are crossed car, to record corresponding bayonet socket identical, and two are crossed cars note
The time difference very little of record, such as less than 1 minute is likely to be then bayonet socket causes more to once crossing to clap car, then exits track
Product process.
Vehicle is generated behind some tracks of many days, it is necessary to be carried out to these tracks in the flow with the embodiment of the present invention
It polymerize to extract trunk track.The method that the following examples provide tracking clustering.
If the first, the bayonet socket quantity no more than preset value that two tracks include, is matched, when each bayonet socket one by one
When identical, judge that two tracks, as same track, are polymerize.
Such as, two tracks for being less than or equal to 3 by bayonet socket number were pressed car time order and function order, entered
Row is matched one by one.If identical, then it is assumed that two tracks are same tracks, are polymerize.For example, track 1：By card
Mouth 121, time 8:05；Bayonet socket 122, time 8:14；Bayonet socket 123, time 8:21.Track 2：By bayonet socket 121, time 7:43；
Bayonet socket 122, time 7:53；Bayonet socket 123, time 7:59.When track 1 and track 2 are matched one by one according to time order and function order,
It is identical, so this two tracks are same tracks.The polymerization of track can include performing following operate：Statistics correspondence track
The total degree of traveling, travels total time, the time point information often travelled etc..Such as, track 1 and track 2 are judged as identical
During track, the travel times of the same trajectories are 2 times, and traveling total time is this running time sum twice, often travel when
Between point can analyze two tracks and draw the time point information of traveling by the time of bayonet socket.
2nd, when two tracks for same vehicle are polymerize, if the bayonet socket quantity that two tracks include is more than in advance
If value, then m bayonet socket of starting, n bayonet socket of end when two tracks is identical, judges two tracks as same track, carries out
Polymerization.M and n can be identical numerical value.
The flowcollector aggregation scheme FlowCollector is when judging whether same trajectories, for by the more track of bayonet socket number, mainly considering rail
Starting bayonet socket, the end bayonet socket of mark, middle bayonet socket is not considered.Because vehicle is during actual travel, as long as original position, knot
Beam position is identical, and is constantly in transport condition, accordingly even when middle of the road is varied slightly, it is also actually that can treat as phase
Same track.
Such as, when track is more than 3 by bayonet socket number, only judge 3 bayonet sockets of starting, the knot of two tracks
3 bayonet sockets of beam pressed car time order and function order, if identical.If identical, then it is assumed that be same track.As an example
Son, vehicle Zhejiang A12345 two tracks are respectively：Track 1 sequentially passes through bayonet socket 121,122,123,124,125；Track 2 according to
Secondary process bayonet socket 258,257,256,255,254；3 bayonet sockets of starting 121,122,123 and the starting 3 of track 2 due to track 1
Individual bayonet socket 258,257,256 is differed, 3 bayonet sockets of end 123,124,125 of track 1 and 3 bayonet sockets 256 of end of track 2,
255th, 254 differ, so this two tracks belong to different tracks, it is impossible to polymerize.Give one example again, track 1 is passed through
Cross bayonet socket 121,122,123,124,125,126,127,128,129,130,131,132；Track 2 by bayonet socket 121,122,
123、211、212、213、214、130、131、132；When pressing car due to 3 bayonet sockets of starting, 3 bayonet sockets of end of two tracks
Between sequencing be identical, so this two tracks are judged as identical track, can be polymerize.
3rd, when two tracks for same vehicle are polymerize, if the bayonet socket quantity that two tracks include is more than in advance
If value, then when having m1 bayonet socket identical in m bayonet socket of starting of two tracks, terminate have n1 bayonet socket identical in n bayonet socket, sentence
Fixed two tracks are similar track, are polymerize；And this two similar tracks are used as the next track to be polymerized of the vehicle
Reference locus, wherein m1 are less than m, and n1 is less than n.
The tracking clustering mechanism is referred to as self study and the approximate match mechanism of similar track.In view of starting m of track
Bayonet socket, n bayonet socket of end, there is also various disturbed conditions such as bayonet socket identification mistake, leakage identifications, therefore add similar track
Self study and approximate match mechanism.Such as, two tracks for being more than 3 by bayonet socket number, if of two tracks
Begin 3 bayonet sockets, 3 bayonet sockets of end, pressed car time order and function order, and had 2 identical, 1 differences, then it is assumed that be similar track,
It is polymerize.And increase the self-study mechanism of similar track：These tracks can be listed in similar track list.Subsequently exist
When carrying out tracking clustering judgement, to all similar tracks of learning records, matched one by one.As long as wherein there is a similar rail
Mark and path matching to be polymerized, then it is assumed that be similar track, polymerize, and the similar track row learnt to final track
In table.It is illustrated below：
Such as：Track A 3 bayonet socket codings of starting are 1,2,3, and it is 4,5,6 to terminate 3 bayonet socket codings；Track B starting
3 bayonet socket codings are 7,2,3, and it is 4,5,8 to terminate 3 bayonet socket codings.When track B is matched with track A, due to preceding 3 bayonet sockets
The bayonet socket that bayonet socket is encoded to 2,3 is matched with A, and the bayonet socket that the bayonet sockets of rear 3 bayonet sockets is encoded to 4,5 is matched with A, therefore track B meetings
A similar track is treated as, while B statistics is added into A, B is learned in similar track list.
Subsequently to track C (C 3 bayonet sockets of starting coding is 7,2,9, terminate 3 bayonet sockets codings be 10,5,8) and rail
When mark A is matched, because the bayonet socket of the similar track B recorded in track C and A 3 bayonet sockets of starting is encoded to 7,2
Match somebody with somebody, the bayonet socket of rear 3 bayonet sockets is encoded to 5,8 matching, therefore can also be treated as similar track, added up by C statistics
While to A, C is learned in final track A similar track list.
By that analogy, by the self study based on similar track list and approximate match mechanism, substantial amounts of path implementation
Polymerization.Because the aggregate rate of track is greatly improved, the disturbing factors such as Car license recognition mistake, identification omission are effectively reduced to identical
