As shown in figure 1, the embodiments of the invention provide a kind of vehicle analysis of agglomeration method, may comprise steps of：

Step 101：Determine that target is detained event.

Step 102：It is determined that at least one first frequent delay bayonet socket that the target is detained the first vehicle of event occurs, And determine at least one second bayonet socket of the first bayonet socket Logic adjacent corresponding with the target delay event.

Step 103：Obtain first bayonet socket, each described second bayonet socket each corresponding delay event respectively.

Step 104：It is performed both by for each the described delay event got：It is determined that currently it is detained event and the mesh Mark the common delay duration of delay event；It is determined that at least one second that current second vehicle for being detained event occurs is frequent It is detained bayonet socket；Judging that the common duration that is detained be not less than the first predetermined threshold value, and described at least one first is frequent stagnant When including first bayonet socket when staying different in bayonet socket and at least one second frequent delay bayonet socket, first car is determined Generate aggregation event between second vehicle.

The embodiments of the invention provide a kind of vehicle analysis of agglomeration method, determines that target is detained event；It is determined that target occurs The each of first vehicle of delay event is often detained bayonet socket, each the of the first bayonet socket Logic adjacent corresponding with target delay event Two bayonet sockets；Obtain the first bayonet socket, each second bayonet socket each corresponding delay event respectively；For each delay event got It is performed both by：It is determined that currently it is detained the common delay duration that event is detained event with target；It is determined that occur current to be detained the of event The each of two vehicles is often detained bayonet socket；Judging that being detained duration jointly is not less than the first predetermined threshold value, and the first bayonet socket is different When for the frequent delay bayonet socket of the first vehicle and the second vehicle when, determine to generate aggregation event between two vehicles.Based on each vehicle In the passage situation of each bayonet socket, it may be determined that vehicle assembles event.Vehicles data amount is big, wide material sources, therefore the present invention is real The False Rate of vehicle aggregation event can be reduced by applying example.

In an embodiment of the invention, bayonet socket can be expressway mouth, traffic light intersection etc., can be collected at bayonet socket By the license plate number of vehicle, and registration of vehicle passage time etc..

In the embodiment of the present invention, for any vehicle, the vehicle through a bayonet socket A by a bayonet socket B when, when used current Between can as the vehicle bayonet socket A delay duration.Under normal circumstances, vehicle first passes through bayonet socket A, then by bayonet socket B, therefore should Being detained duration can think that transit time of the vehicle in bayonet socket B subtracts the difference of the transit time in bayonet socket A.

Wherein, bayonet socket A and bayonet socket B can be same bayonet socket, or different bayonet sockets.

Such as one vehicle can be after some bayonet sockets in way of driving a vehicle, bayonet socket A and bayonet socket B can be the two of arbitrary neighborhood Individual bayonet socket, it might even be possible to close on crossing for any non-conterminous two.

For another example, it is assumed that after a bayonet socket, car owner gets off and stopped the vehicle, for example car owner goes home, car owner a to mesh Ground it is state-run etc., car owner gets on the bus and driven after stopping certain time, then vehicle can be through the bayonet socket backtracking, in this way, bayonet socket A It is same bayonet socket with bayonet socket B.

Based on the above, in the embodiment of the present invention, when delay duration of the vehicle in bayonet socket A is not less than respective settings threshold value When, it is believed that there occurs be detained event in bayonet socket A for the vehicle.

In the embodiment of the present invention, effective car quantity excessively between two bayonet sockets can also be determined：For above-mentioned bayonet socket A and bayonet socket B, No matter through bayonet socket A by bayonet socket B, or through bayonet socket B by bayonet socket A, as long as determining that a vehicle is used between two bayonet sockets Transit time when being not more than respective settings threshold value, effective car quantity of crossing between bayonet socket A and bayonet socket B adds 1.

Based on the above, in the embodiment of the present invention, if in corresponding preset time period, effective between two bayonet sockets crosses car number When amount is not less than respective settings threshold value, it is believed that two bayonet socket Logic adjacents.

Based on the above, in the embodiment of the present invention, situation is detained according to the bayonet socket of each vehicle, it may be determined that any two Common delay duration of the vehicle at any bayonet socket, if the common delay duration is not less than respective settings threshold value, it is believed that should There occurs aggregation event at this bayonet socket for two vehicles.

For example, vehicle 1 is in 13:00 by bayonet socket A, after being detained 5h, in 18:00 returns through bayonet socket A again, vehicle 2 In 14:00 by bayonet socket A, after being detained 4.5h, in 18:30 by bayonet socket B, in this way, the common holdup time section of the two vehicles Can be 14:00~18:00, it may thereby determine that out the two vehicles a length of 4h in bayonet socket A common delay.

Based on the above, in the embodiment of the present invention, according to two vehicles delay duration at bayonet socket A respectively, and Both bayonet socket A common delay duration, can be directed to vehicle aggregation event, further determine that holdup time similarity.

Such as situation 1：The a length of 5h in bayonet socket A delay of vehicle 1, vehicle 2 a length of 4.5h in bayonet socket A delay, two Person a length of 4h in bayonet socket A common delay；

Situation 2：The a length of 5h in bayonet socket A delay of vehicle 1, vehicle 2 a length of 4.5h, Liang Zhe in bayonet socket A delay A length of 1h during bayonet socket A common delay；

Situation 3：The a length of 10h in bayonet socket A delay of vehicle 1, vehicle 2 a length of 4.5h, Liang Zhe in bayonet socket A delay A length of 4h during bayonet socket A common delay；

For above-mentioned three kinds of situations, it is believed that the holdup time similarity in situation 1, it is higher than situation 2, also compare situation 3 is high.

Based on the above, in the embodiment of the present invention, for any vehicle, the institute of delay event occurs for the vehicle There is bayonet socket, if the vehicle is when the number that delay event occurs for a bayonet socket is relatively more, it is believed that the bayonet socket is the vehicle Often it is detained bayonet socket.Under normal circumstances, the number of the frequent delay bayonet socket of any vehicle is at least one.Such as user residence Ground, user are easily confirmed as often being detained bayonet socket with handling official business.

Based on vehicle defined above be detained duration, be detained event, between bayonet socket it is effective cross car quantity, bayonet socket Logic adjacent, Vehicle aggregation, holdup time similarity, vehicle are often detained bayonet socket etc., vehicle provided in an embodiment of the present invention can be assembled and divide Analysis method carries out further specific limit.

In an embodiment of the invention, in order to illustrate a kind of possibility implementation for determining target and being detained event, so, The step 101, including：

A3：According to following formula (1), calculate and be detained duration corresponding to the current record of current bayonet socket；

A4：Judge whether the delay duration is not less than the second predetermined threshold value, if so, determine that the target is detained event, And step 102 is performed, otherwise, using the current record of next bayonet socket as the current record of current bayonet socket, and perform A2；

In detail, staff can set above-mentioned first preset time period, above-mentioned second predetermined threshold value on demand.Such as Above-mentioned first preset time period can be the same day, this month, nearly 3 months.If it is considered as just to be detained to reach 1h, thus it is above-mentioned second pre- If threshold value can be 1h.

In detail, when staff thinks to need to analyze above-mentioned first vehicle, the license plate number of first vehicle It will be designated, so as to obtain the current record of the bayonet socket of first vehicle in a preset time period.Under normal circumstances, each card The current record of mouth may each comprise vehicles identifications, bayonet socket mark, transit time.When being detained for convenience of the vehicle calculated at each bayonet socket Between, can be according to bayonet socket current record carry out order arrangement of the time order and function order to collecting.

Then, based on the current record of the bayonet socket arranged, delay duration of first vehicle at each bayonet socket can be calculated, and Contrasted with respective threshold, if being not less than threshold value, illustrate that the first vehicle holdup time at the bayonet socket is longer, it is stagnant so as to exist Event is stayed, if being less than threshold value, can continue to calculate next delay duration.

When determining to exist delay event, i.e., when above-mentioned target is detained event, it can perform and be detained thing for the target Part, perform above-mentioned steps 102.

But when the duration of above-mentioned first preset time period is longer, in the bayonet socket communications records collected, above-mentioned first Vehicle may have multiple delay events.In this way, after above-mentioned steps 101 to step 104 has been performed, can determine again Each is detained event, and each delay event for determining, repeats above-mentioned steps 101 to step 104.

Certainly, in an alternative embodiment of the invention, can also be determined whole according to the bayonet socket communications records collected Delay event, and each delay event for determining, above-mentioned steps 101 are performed respectively to step 104.

It is worth what is proposed, for example, the first preset time period is the 8 of the same day:The 8 of 00 to next day:00, the second default threshold It is worth for 1h, if the transit time of the current record of the bayonet socket for being arranged in last position is the 21 of the same day:00, due in the absence of next bayonet socket Current record, it is apparent that vehicle was in the 21 of the same day:The 8 of 00 to next day:Between 00, do not pass through any bayonet socket, vehicle in 11h It is detained.Therefore, it is to calculate to be detained duration, in above-mentioned formula (1), calculation during i ＜ n and i=n is different.

Based on the above, in an embodiment of the invention, vehicle can be built and be detained event computation model：Utilize Hadoop MapReduce distributed computing frameworks, calculating analysis is carried out to the delay event of the magnanimity given category number-plate number. According to specified license plate number, retrieve in Hbase databases, the vehicle at the appointed time current record of the bayonet socket in section, and with logical Row time order and function order arranges, and forms result set LIST1；Traversing result collection LIST1, since recording Article 2, this record Transit time subtracts a record transit time, is holdup time of the vehicle in a upper bayonet socket；If during the delay Between be more than setting time threshold value T₀, then the license plate number, upper bayonet socket transit time, this bayonet socket transit time, a upper bayonet socket are compiled Number, this bayonet socket numbering, the holdup time be recorded in Hbase be detained event table in.

In detail, the delay event of each vehicle can determine in advance before above-mentioned steps 101 to step 104.Such as This, staff can be as needed, is detained event using any delay event as target, to carry out subsequent analysis.

In an embodiment of the invention, in order to illustrate a kind of possibility implementation for determining often to be detained bayonet socket, so, Further comprise before the step 102：

For at least one number calculated, maximum times therein are determined；

It is performed both by for each the described number calculated：According to following formula (2), calculate current number with it is described most First difference of big number；When judging that first difference is not more than three predetermined threshold values, the current number pair is recorded The 3rd bayonet socket answered often is detained bayonet socket for the first of first vehicle；

In detail, the frequent delay bayonet socket of any vehicle is analyzed, it is necessary first to collect the vehicle and delay event be present All bayonet sockets, i.e., above-mentioned at least one 3rd bayonet socket.Wherein it is possible to recorded according to the vehicle pass-through of the bayonet socket collected, base In the holdup time corresponding to each bayonet socket calculated, to determine each the 3rd bayonet socket.

For example, it is computed, in the range of nearly 1 year, according to the order of number from big to small, the first vehicle is each Three bayonet sockets occur delay event number be respectively：Bayonet socket 01：20000 times, bayonet socket 03：1.5 ten thousand times, bayonet socket 10：0.8 ten thousand times, card Mouth 04：0.1 ten thousand times, bayonet socket 06：0.09 ten thousand times ....In this way, maximum times be 20,000 times, be computed, 20,000 times with 20,000 times First difference is 0%, and 1.5 ten thousand times and first difference of 20,000 times are 25%, and 0.8 ten thousand times and first difference of 20,000 times are 60%. Assuming that above-mentioned 3rd predetermined threshold value is 30%, then in above-mentioned bayonet socket, only bayonet socket 01 and bayonet socket 03 are the frequent delay of the first vehicle Bayonet socket.

In an alternative embodiment of the invention, calculate the first vehicle each 3rd bayonet socket occur delay event number it Afterwards, each number and a setting value can equally be contrasted, if being not less than setting value, may be considered the first vehicle Frequent delay bayonet socket.For example the designated value, when being 0.5 ten thousand times, in above-mentioned bayonet socket, bayonet socket 01, bayonet socket 03 and bayonet socket 10 are The frequent delay bayonet socket of first vehicle.

Based on the above, in an embodiment of the invention, vehicle can be built and be often detained bayonet socket computation model：Profit With Hadoop MapReduce distributed computing frameworks, calculating point is carried out to the delay event of the magnanimity given category number-plate number Analysis.According to the vehicle at the appointed time current record of the bayonet socket in section, and with logical in specified license plate number retrieval Hbase databases Row time order and function order arranges, and forms result set LIST2；Traversing result collection LIST2, since recording Article 2, this record It is holdup time of the vehicle in a upper bayonet socket that transit time, which subtracts a record transit time, if the holdup time More than setting time threshold value T2, then the license plate number is detained number in the long-time of a upper bayonet socket and adds 1.After the completion of traversal, for The delay number that each license plate number corresponds to bayonet socket finds out the bayonet socket being often detained using clustering algorithm.

In detail, the frequent delay bayonet socket of each vehicle can determine in advance before above-mentioned steps 101 to step 104.

According to the above, any vehicle can be directed to, determines that it is often detained bayonet socket, the embodiment of the present invention is not made herein Repeat.

In an embodiment of the invention, in order to illustrate a kind of possibility implementation for determining bayonet socket Logic adjacent, so, Further comprise before the step 102：Determine at least one 4th bayonet socket, wherein, first bayonet socket with it is any described Distance between 4th bayonet socket is not more than the 5th predetermined threshold value；

In detail, physical distance of any of the above-described 4th bayonet socket generally between the first bayonet socket is nearer.

In detail, above-mentioned current duration used, is not only related to the vehicle pass-through from current 4th bayonet socket to the first bayonet socket Record, also relate to and recorded from the first bayonet socket to the vehicle pass-through of current 4th bayonet socket.

Based on the above, in an embodiment of the invention, bayonet socket neighborhood calculation model can be built：Utilize Hadoop MapReduce distributed computing frameworks, car data is crossed to magnanimity bayonet socket and carries out calculating analysis.Retrieve the vehicle in specified time section The current record of bayonet socket, and arranged with the number-plate number, transit time sequencing, form result set LIST3；Traversing result collection LIST3, since Article 2 record, by this bayonet socket G2 transit time subtract it is upper one record by bayonet socket G1 it is current when Between, be the vehicle in the holdup time of a upper bayonet socket, if the holdup time is less than setting time threshold value T3, by G1- G2 is effective to cross car quantity record plus 1；Until traversal is completed, some adjacent bayonet sockets and effective key-value pair collection for crossing car quantity are obtained Close, such as { " G1-G2 "：200000, " G1-G3 "：100000, " G4-G5 ":10000 ... ... }；Travel through this set, if certain two The effective car quantity of crossing of individual bayonet socket is more than threshold value N1, then this two bayonet sockets regard as Logic adjacent bayonet socket.

In detail, each Logic adjacent bayonet socket can determine in advance before above-mentioned steps 101 to step 104.

In an embodiment of the invention, in the step 104, further comprise：Judge the current delay event It is detained whether duration is not less than the 7th predetermined threshold value, if so, perform the current event of being detained of the determination is detained thing with the target The common delay duration of part.

As an example it is assumed that vehicle when the delay duration of a bayonet socket exceedes setting value 1h, that is, is thought delay event occurs, So as to screen out some holdup times shorter vehicle pass-through situation on a large scale.When analyzing for specific aggregation event When, can further it be screened out according to the delay duration for being detained event.I.e. aggregation is generally detained, but is detained and is not necessarily assembled.

Such as, it is necessary to when analyzing gambling situation, it is contemplated that the duration that lasts of gambling is generally no less than half a day, therefore 7th predetermined threshold value can be defined as 5h.In this way, when though a delay duration for being detained event is more than 1h but during not less than 5h, The delay event can be screened out, without calculating common delay duration and follow-up process, this implementation can be full While sufficient demand, greatly reduce data amount of calculation.

Similarly, in above-mentioned steps 104, it is desirable to which the common duration that is detained is not less than the first predetermined threshold value.For example assembled a crowd about dividing During gambling situation, first predetermined threshold value can be defined as 4h.If although one is detained event and is detained duration more than 5h, its with When target is detained the common delay duration only 0.5h of event, because common delay duration is shorter, it is believed that both do not gather Crowd's gambling, i.e., do not produce aggregation event.

Judgement for assembling event, for example, the resident family of same cell, both of which are detained in a bayonet socket, and jointly It is detained duration to meet to require, but both are actually in the limit of consideration of analysis gambling situation, therefore in above-mentioned steps 104 In, it is desirable to it is the first vehicle and the frequent delay bayonet socket of the second vehicle during the first bayonet socket difference.

In this way, when assert the aggregation of two vehicles, the first bayonet socket can meet following either conditions：

Condition 1：First bayonet socket is often detained bayonet socket for the one of the first vehicle；

Condition 2：First bayonet socket is often detained bayonet socket for the one of the second vehicle；

Condition 3：First bayonet socket is neither the frequent delay bayonet socket of the first vehicle, is not also the frequent delay card of the second vehicle Mouthful.

Based on the above, when judging aggregation event, processing considers common delay duration, is detained duration, is often detained Outside bayonet socket, it is that big data operand is reduced on the basis for ensureing judgment accuracy, holdup time phase can be determined whether Like degree.

In detail, for above-mentioned condition 1 or condition 2, there may be following situations 1：

When user A goes to the user B family to act as a guest, the holdup time of vehicle is generally relatively long used in user A, car used in user B Holdup time it is generally relatively short.Such as 18 on the day of user A:During 00 goes back home, and in next day 8:00 is away from home, then Holdup time is 14h, 18 on the day of user B:30 act as a guest into user A family, and in the same day 21:30 leave, then the holdup time is 3h。

In detail, for above-mentioned condition 3, there may be following situations 2：

User A and user's B phases a restaurant of dividing out are had a dinner party, and the holdup time of vehicle used in user A and user B is generally relatively It is short.For example user A is in 13:00, which sets out, reaches restaurant and in 15:00 leaves, then holdup time 2h, user B is in 12:45 go out It is dealt into up to restaurant and in 15:00 leaves, then holdup time 2.25h.

Contrast situation 1 and situation 2, it can be seen that the holdup time similarity in situation 1 is relatively low, stagnant in situation 2 Stay time similarity of a relatively high, in this way, above-mentioned 3 kinds of modes can be directed to, different decision thresholds is set.

Based on the above, in an embodiment of the invention, in order to illustrate that one kind is determined according to holdup time similarity The possibility implementation of adopted aggregation event, so, in the step 104, further comprise：According to following formula (3), institute is calculated State the holdup time similarity that current delay event is detained event with the target；

In summary, in an embodiment of the invention, vehicle aggregation event computation model can be built：Utilize Hadoop MapReduce distributed computing frameworks, result set caused by vehicle delay event computation model is analyzed, analysis is every one by one Individual delay event.Specifically include following flows：(1) bayonet socket G1 where target is detained event is obtained；(2) according to bayonet socket neighborhood calculation Model, the bayonet socket set M1 of all Logic adjacents of bayonet socket G1 is searched, and will separately increase bayonet socket G1 itself in M1；(3) according to bayonet socket Set M1, search the vehicle that all bayonet sockets occur in set and be detained event sets M2；(4) traversal is detained event sets M2, by it In every be detained event and carry out com-parison and analysis with current event of being detained, from be detained duration, to be detained duration, holdup time jointly similar Degree, vehicle judge that duration is more than respective threshold, the common duration that is detained is more than corresponding threshold if be detained in terms of being often detained bayonet socket Value, holdup time similarity are more than respective threshold, and are that the vehicles of two vehicles is often detained bayonet socket when being detained bayonet socket difference, then Two cars for judging currently to compare generate aggregation event.
