In the following, by further being illustrated the embodiment of the present invention with reference to Fig. 2：
The acquisition of step 1, mobile phone signaling data：
According to the principle of global mobile communication, switch location technology using Mobile Location Technology and mobile phone, transported by mobile
The mobile phone signaling acquisition system for seeking business obtains mobile phone signaling data, and the mobile phone signaling in preset time is mainly gathered in the present embodiment
Data, such as intraday mobile phone signaling data.Mainly include in the mobile phone signaling data of acquisition：International mobile subscriber identifier
Treated result MSID, time stamp T ime, Location Area Code LAC, cellular cell number Cell ID and thing that IMSI, IMSI be anonymous
Part type Event ID.
Step 2, data prediction：
Intraday mobile phone signaling data enormous amount, it is therefore desirable to be processed for mobile phone signaling data in data
Management and reduce data processing complexity.The mobile phone signaling data of acquisition is pre-processed, first, in accordance with passenger's
Travel time sorts, and the main of pretreatment that the mobile phone signaling data of passenger after sequence carries out is included：
First, the invalid information and missing data in original mobile phone signaling data are rejected；Invalid information refers in data
In gatherer process, since signal acquiring system and the system performances such as cordless communication network is unstable cause the mobile phone signaling number of passenger
According to recording not exclusively and losing, the identification of urban track traffic trip route is imperfect, goes out including None- identified into website, goes out website
Or website etc. is changed into judge, because the missing of mobile phone signaling data can not match corresponding website.
One complete mobile phone signaling data includes multinomial data item, in order to effectively analyze mobile phone user's travel behaviour point
Analysis by simplifying to original mobile phone signaling data, i.e., simplifies to being based on the required data item of position analysis, only protects
It stays based on the required data item of position analysis.These data item include：At international mobile subscriber identifier IMSI, IMSI anonymity
Result MSID, time stamp T ime, Location Area Code LAC, cellular cell number Cell ID and event type Event ID after reason.
It might have data acquisition missing during the collection of data, therefore can be positioned according to 3 points：The signaling data of collection
3 effective time stamps (into website, intermediate station goes out website) and position area number at least to be included because in practice, multiplying
Visitor is removed by information such as transfer stops, at least to include entering the station with it is outbound.Invalid data mainly pass through：First, missing data, data
There are the data that field value is sky in row.2nd, identical repeated data exists complete in signaling event database of record
Repeated data, i.e., all fields are identical, during the appearance of this repeated data is there are signaling record generation and number
According to storing process in.3rd, invalid Event ID data item filtering, some are triggered in the signaling of Fail Types, since failure is former
Because unknown, therefore this part signaling records the actual position of the possible simultaneously non-user of reacted location information.
2nd, data integrity inspection；Integrity check out of the station is the integrality to a track traffic travel behaviour
It tests, including：
The validity check of time：Passenger, according to the size of trip distance, always expends one in track traffic trip
Time in a zone of reasonableness.Using mobile phone signaling data identify in once trip into website and website is gone out, theoretically regard
For a trip route.Pass through the setting time threshold progress between website is changed to for the track traffic passenger of secondary trip more than a day
Differentiate, if it exceeds certain threshold valueIt is then rejected from this trip, i.e. the Rule of judgment of the validity check of time is：WhereinRepresent the passenger of monitoring into the website time,Represent when the going out website of passenger of monitoring
Between,Represent the threshold value set according to the travel time of subway line.
Space finiteness is examined：Dubious zone, which is examined, mainly carries out the integrality of a track traffic travel behaviour
It examines.Once complete track traffic trip includes at least behavior and the outbound behavior of entering the station.On the one hand in data analysis, track
It in the matching of traffic trip website, can not carry out judging the behavior of disengaging website, the matching of trip website be caused to be omitted, although can
By other intermediate stations differentiate in fullpath that the passenger goes on a journey in this subway, also it is judged as route matching not
Completely, this trip is rejected according to the principle of validity.
By carrying out the inspection of data integrity and uniformity to the mobile phone signaling data collected, data can be eliminated and made an uproar
Sound, removal are recorded with the signaling that passenger's actual activity track is not inconsistent, and identify the signaling record of true reflection individual activity.Noise number
According to mainly invalid redundant data and the abnormal data when path is identified, the abnormal data such as drift data and table tennis
Data etc...
3rd, it is combined with track traffic base station database, filters out the trip user of subway, reduces the calculating work of sample
Make.
Step 3 expands sample and contracting sample：
Since the total and actual track traffic passenger of the passenger identified in practice using mobile phone signaling data is total
Number is inconsistent, on the one hand might have the gaps and omissions of information gathering, makes data smaller than real data；On the other hand；Current intelligence
Energy mobile phone support double-card dual-standby or a passenger have a case that the mobile phone of two, are actually subjected to the data collected ratio big.
Expansion sample for data can carry out expansion sample using current AFC data, while carry out data contracting according to the historical data of acquisition
Sample.
Data contracting sample is compared according to history AFC data, if the mobile phone signaling data of acquisition is much larger than AFC numbers
According to, then comparing is carried out in the mobile phone sig data information storehouse of the passenger of urban track traffic, if discovery different identity
The passenger of No. MSID, and all in the same time in multiple trip, which is accurate to the second, that is by No. MSID of different identity
Passenger is considered as same passenger, rejects other passengers, only retains the mobile phone signaling data of a passenger.
Since signal acquiring system and the system performances such as cordless communication network is unstable cause subscriber signaling data record not
It completely and loses, it is therefore desirable to data be carried out to the mobile phone signaling data collected and expand sample.Pass through the mobile phone signaling that will be collected
Data are compared with urban track traffic trip customer data base, if the mobile phone signaling data collected is considerably less than AFC
The user of system acquisition, then increase the quantity of mobile phone signaling data by the historical data of AFC.It can be adopted by AFC system
The historical data volume of the flow of passengers of collection, which is configured, expands the ratio of sample to carry out data expansion sample.
Step 4 establishes data message storehouse：
In the present invention in embodiment, traffic information is extracted using mobile phone signaling data, it is necessary to by urban track traffic
The base station information data of communication network and the geographic information data of Metro Network, by establishing track traffic base station information number
According to the geographic information database GIS of storehouse and Rail traffic network (Geographic Information System), mobile phone is believed
The location information of data is made to be mapped on actual geographical location.The process of the mapping includes：Believed according to the initial mobile phone of mobile phone
Make the number of the Location Area Code LAC in data and cellular cell number Cell ID that mobile phone are located in corresponding base station and radiate model
In enclosing, longitude and latitude is positioned further according to geographic information database, so as to obtain the routing information of passenger's trip.The routing information includes
The travel route of passenger such as enters from A websites, and goes out from B websites, wherein have passed through C stations and D stations, which can be from
It is shown in display device in the form of map.
Step 5, the identification of track traffic passenger trip route：
The identification in passenger path mainly includes the identification into website, changes to the identification of website, the identification of intermediate station, goes out website
Identification.
If the location information that mobile phone uploads at the i moment is：P(UIDP；LACi；CIi；t；EventIDi), wherein：UIDPIt represents
The Customs Assigned Number of passenger P, LACiRepresent the corresponding LAC numbers in i moment positions, CIiRepresent the corresponding base station of i moment location informations
Number, wherein, t=tiRepresent location updating time, EventIDiRepresent i moment corresponding event type.Routing information is carried out
The step of identification, includes：
(1) the mobile phone signaling data of the passenger screened in step 3 is ranked up according to the time order and function of generation；
(2) differentiated successively by the time order and function order of the mobile phone signaling data of passenger, as P (UIDP；LACi；t；
EventIDi) first appear LACi∈Set{LACLineNAnd CIi∈Set{CIk, while EventIDiIt is updated for spanning position area
During event, then by CIiEnter the station website of the corresponding subway station as passenger.
(3) continue to differentiate the mobile phone signaling data of same passenger, if first appearing P (UIDp；LACi+m；CIi+m；
ti+m；EventIDi+m), wherein：CIi+n-1∈Set{CIk, LACi+m∈Set{LACLineN}。CIi+m∈Set{CIk, work as LACi+m
≠LACi, m>0, meanwhile, EventIDiFor the update event of spanning position area when, then assert CIi+nCorresponding subway station multiplies for this
The one of transfer website of visitor's trip.
(4) continue to differentiate on the basis of (3) step, if signaling P (UIDp；LACi+n；CIi+n；EventIDi+n) formula
Middle n ＞ m,LACi+n-1∈Set{LACLineN, CIi+n-1∈Set{CIk, meanwhile, EventIDi+nFor
When spanning position area updates, then CI is asserti+n-1The outbound website that corresponding subway station is this time gone on a journey for passenger, terminates this path
Identification.
(5) in practice, passenger there is a situation where repeatedly to take subway, thus repeat step (2), (3), (4) after
Continuous that mobile phone signaling data is identified, until all mobile phone signaling datas, all identification finishes.The recognition result that will be obtained
Establish database out of the station.
The preservation form of disengaging subway station information is in the database out of the station：
Wherein, UIDPRepresent the Customs Assigned Number of passenger P,It represents
The trip of passenger's P x: ths subway is entered the station the time,Represent the outbound time of passenger's P x: ths subway trip,Represent passenger
P enters the station the corresponding base station number of website,Represent the outbound time point of passenger's P x: ths subway trip for base station number.
Step 6, subway route distinguishing validity：
Passenger can tentatively be obtained in track traffic trip into website, transfer stop by being matched by base station with subway station
Point goes out website.But the loss of data, nothing may be caused due to the problem of signal transmission during actual data acquisition
Method matching trip website.Therefore need to carry out validity check to matched website.
Validity check mainly includes：First, to the inspection of the origin and destination integrality of trip, mainly route matching is being carried out
The missing for finding to have the website either outbound website that enters the station in the process then assert that this time trip is invalid, during once going on a journey
Setting is entered the station the timeWith the outbound timeThere are interval thresholdsIfThen judge multiple travel behaviour.
2nd, to changing to the rational inspection of website, test mainly for the reasonability of transfer website.
The matching of step 7, passenger's riding scheme based on route map of train：
The specific path of passenger can be identified by step 3,4,5, can monitor passenger by mobile phone signaling data arrives
