Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the method and system for identifying bus trips of a mobile phone user provided by the present invention are described in detail below with reference to the accompanying drawings.
The method and the system for identifying the mobile phone user bus trip provided by the invention can be used for identifying whether the mobile phone user adopts the bus trip at a certain specific time period.
Fig. 1 is a flowchart of a method for identifying a public transportation trip of a mobile phone user according to an embodiment of the present invention, and as shown in fig. 1, the method includes:
and step S1, acquiring the identification data of the mobile phone terminal in the period to be identified.
The identification data of the mobile phone terminal in the period to be identified comprises: the mobile phone terminal comprises the starting time of the period to be identified, the ending time of the period to be identified, the position information of the mobile phone terminal at the starting time of the period to be identified and the position information of the mobile phone terminal at the ending time of the period to be identified.
For convenience of description, the identification data of the period to be recognized is denoted as [ (a1, B1), (a2, B2) ], where a1 represents the start time of the period to be recognized, a2 represents the end time of the period to be recognized, B1 represents the position information of the handset terminal at the start time of the period to be recognized, and B2 represents the position information of the handset terminal at the end time of the period to be recognized. Optionally, the location information is latitude and longitude information.
And step S2, according to the position information of the mobile phone terminal at the starting time of the period to be identified, determining the bus stop closest to the mobile phone terminal at the starting time of the period to be identified, recording the bus stop as a first bus stop, and calculating the first distance between the mobile phone terminal and the first bus stop.
According to the pre-acquired bus running route data and the position information B1, a bus stop closest to the position information B1 is determined and recorded as a first bus stop, and a first distance between the first bus stop and the position information B1 is calculated.
It should be noted that the bus operation route data in the present invention includes two parts, wherein one part records the position information of all bus stops in the bus operation network, and the other part records the driving route of each bus (stop-and-go bus stop) in the bus operation network.
In step S2, as an alternative, the distance between the position information B1 and each bus stop in the bus operation network may be calculated, and then the calculated distances may be sorted to determine the first bus stop closest to the position information B1 and the corresponding first distance.
It should be noted that other manners may also be adopted in the present invention to determine the first bus stop closest to the position information B1 and the corresponding first distance; for example, whether a bus stop exists is searched in an area with the position information B1 as a center and a preset length (which can be adjusted according to actual conditions) as a radius; if not, increasing the value of the preset length, and searching again; if 1 bus stop exists, the bus stop is a first bus stop, and a first distance between the first bus stop and the position information B1 is calculated; if 2 or more bus stops exist, the distances between the bus stops and the position information B1 are respectively calculated, the bus stop with the minimum distance is the first bus stop, and the minimum distance is the first distance. In the present invention, the technical means employed to determine the first bus stop and the first distance are not limited.
And step S3, according to the position information of the mobile phone terminal at the ending time of the period to be identified, determining the bus stop closest to the mobile phone terminal at the ending time of the period to be identified, recording the bus stop as a second bus stop, and calculating a second distance between the mobile phone terminal and the second bus stop.
Based on the same principle as in step S2, the second bus stop closest to the position information B2 and the corresponding second distance may be determined.
In the present invention, the technical means used for determining the second bus stop and the second distance is not limited.
The bus stops closest to the mobile phone terminal at the starting time and the ending time of the period to be identified and the corresponding distances can be determined through the steps S2 and S3.
And step S4, identifying whether the travel mode of the mobile phone terminal holding user in the period to be identified is a bus travel or not according to the first distance and the second distance.
In step S4, it can be identified whether the holding user of the mobile phone terminal is on a bus trip in the period to be identified according to a first distance between the mobile phone terminal and a first bus stop closest to the mobile phone terminal at the start time of the period to be identified and a second distance between the mobile phone terminal and a second bus stop closest to the mobile phone terminal at the end time of the period to be identified.
Fig. 2 is a specific flowchart of step S4 in the present invention, and as shown in fig. 2, as an alternative, step S4 includes:
step S401, judging whether the first distance and the second distance are both smaller than a first preset distance.
In step S401, if it is determined that both the first distance and the second distance are smaller than the first preset distance, step S402 is executed; otherwise, step S404 is performed.
And S402, judging whether buses passing through the first bus stop and the second bus stop in sequence exist or not based on the bus running line data.
The running routes of the buses are recorded in the bus running route data, and the running routes of the buses can be screened to determine whether the buses passing through the first bus stop and the second bus stop in sequence exist.
In step S402, if it is determined that there are buses passing through the first bus stop and the second bus stop in sequence, step S403 is executed; otherwise, step S404 is performed.
And S403, recognizing that the travel mode of the user holding the mobile phone terminal in the period to be recognized is bus travel.
And S404, recognizing that the travel mode of the holding user of the mobile phone terminal in the period to be recognized is not bus travel.
Through the steps S401 to S404, whether the mobile phone terminal user is in a bus trip or not in the period to be identified can be identified.
It should be noted that, in step S4, other algorithms may be further used to identify whether the holding user of the mobile phone terminal uses a bus trip in the period to be identified. For example, when it is determined that both the first distance and the second distance are smaller than the first preset distance, the travel mode of the user holding the mobile terminal in the period to be identified is directly identified as a bus travel (the determination in step S402 is not required). It should be known to those skilled in the art that all technical means for identifying whether the travel mode of the mobile phone terminal holding user in the period to be identified is bus travel based on the first distance and the second distance belong to the protection scope of the present invention.
The embodiment of the invention provides a method for identifying public transport trips of a mobile phone user, which can effectively identify whether the trip mode of the mobile phone terminal holding user in the period to be identified is public transport trips or not according to identification data of the mobile phone terminal in the period to be identified, and enriches the research range of the user behavior analysis field.
Fig. 3 is a flowchart of a method for identifying a bus trip of a mobile phone user according to a second embodiment of the present invention, and as shown in fig. 3, the method includes:
and step S01, acquiring the user travel mode characteristic data element of the mobile phone terminal in real time.
In step S01, relevant data of the mobile phone terminal may be collected in real time, where the relevant data includes: the vertical direction vibration displacement number of the mobile phone terminal, the longitude and latitude information of the mobile phone terminal and the data acquisition time. Each time the relevant data is collected, one user trip mode characteristic data element can be generated by packaging and is marked as (a, b, c); wherein, a is the vertical vibration displacement number of the mobile phone terminal, b is the longitude and latitude information of the mobile phone terminal, and c is the data acquisition time.
The packaging format of the user travel mode feature data elements is as follows:
| number of vertical vibration displacements | Latitude and longitude information | Time of data collection |
| a | b | c |
And step S02, determining the measure vibration-free time period of the mobile phone terminal according to the acquired vibration displacement data in the vertical direction.
In step S02, based on the data of the vertical vibration displacement number of the mobile phone terminal obtained in step S01 changing with time, a measure vibration-free time period of the mobile phone terminal may be determined, and the identification data of the measure vibration-free time period are marked as [ (a1, b1, c1), (a2, b2, c2) ]; wherein, (a1, b1, c1) represents the user travel mode feature data elements acquired at the starting time of the measure no-vibration period, (a2, b2, c2) represents the user travel mode feature data elements acquired at the ending time of the measure no-vibration period;
[ (a1, b1, c1), (a2, b2, c2) ] satisfies the following condition:
under the condition one, c1 is selected from a time when the vertical direction vibration displacement number of the mobile phone terminal jumps from non-zero to zero, and c2 is selected from a time when the vertical direction vibration displacement number of the mobile phone terminal jumps from zero to non-zero.
It should be noted that, when the holding user of the mobile phone terminal is in a bus riding state, since the vehicle runs relatively stably, the mobile phone terminal basically does not generate vibration displacement in the vertical direction, and therefore, in the time period of taking the bus, the vertical vibration displacement number of the mobile phone terminal is continuously zero.
For convenience of description, at any time t, if the vibration displacement number of the mobile phone terminal in the vertical direction is changed from nonzero to zero, the time t is called the negative singular point time of the mobile phone terminal; if the vertical vibration displacement number of the mobile phone terminal is changed from zero to non-zero, t is called the positive singular point moment of the mobile phone terminal.
c1 is a negative singularity time (corresponding to the time of getting on the vehicle by the user) and c2 is a positive singularity time (corresponding to the time of getting off the vehicle by the user).
Conditions two, c1, and c2 satisfy: c2-c1 is alpha, alpha is a preset constant.
Wherein, alpha can be determined according to the minimum value of the normal driving time between all adjacent stations in the bus running network; in practice, α should be greater than or equal to the minimum value of the normal travel time between all adjacent stations in the bus operating network.
Condition three, the measure of the four-dimensional space curve with the endpoints of (a1, b1, c1) and (a2, b2, c2) is 0 formed by the user travel mode feature data elements collected in the time period of c1 to c 2; wherein, the measure of the four-dimensional space curve refers to: and (3) projecting the four-dimensional space curve phi to a three-dimensional space where the (a, b) is located to obtain a three-dimensional space curve gamma, projecting the three-dimensional space curve gamma to a plane where the longitude and latitude information b is located to obtain a two-dimensional space curve L, and measuring a three-dimensional space curved surface area S defined by the three-dimensional space curve gamma and the two-dimensional space curve L to obtain the four-dimensional space curve phi.
In step S02, mining in real time whether there is a measure non-vibration period satisfying the above three conditions; if so, taking the measurement non-vibration time interval as the time interval to be identified to enter the step S1; if not, the excavation is continued.
The following steps S1 to S4 are specifically described:
and step S1, acquiring identification data of the mobile phone terminal in the measurement vibration-free time period.
And step S2, according to the position information of the mobile phone terminal at the initial time of the measured non-vibration time period, determining the bus stop closest to the mobile phone terminal at the initial time of the measured non-vibration time period, recording as a first bus stop, and calculating the first distance between the mobile phone terminal and the first bus stop.
And step S3, according to the position information of the mobile phone terminal at the ending time of the measured no-vibration time period, determining the bus stop closest to the mobile phone terminal at the ending time of the measured no-vibration time period, recording the bus stop as a second bus stop, and calculating a second distance between the mobile phone terminal and the second bus stop.
In step S4, it can be identified whether the holding user of the mobile phone terminal is on bus travel in the measurement non-vibration period according to a first distance between the mobile phone terminal and a first bus stop closest to the mobile phone terminal at the start time of the measurement non-vibration period and a second distance between the mobile phone terminal and a second bus stop closest to the mobile phone terminal at the end time of the measurement non-vibration period.
For the description of step S1 to step S4, reference may be made to the contents of the first embodiment, and details are not repeated here.
In the embodiment, the characteristic data elements of the user trip mode of the mobile phone terminal are obtained in real time, and after the measure non-vibration time period is found, the measure non-vibration time period is used as the time period to be identified, so that whether the trip mode of the user holding the mobile phone terminal in the measure non-vibration time period is bus trip or not is identified. When the travel mode of the mobile phone terminal holding user in the measurement vibration-free time period is recognized as bus travel, the first bus stop can be determined as the getting-on stop of the mobile phone terminal holding user, and the second bus stop is the getting-off stop of the mobile phone terminal holding user.
