Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Public transport networks in cities are complex, the geographic positions of different public transport lines are distributed differently, functional areas of peripheral cities are different, and people covering passengers are different, so that advertisement audiences of different public transport lines and different time periods are different, and the different types of advertisements are different in reverberation. The method enables the accurate delivery of the bus-mounted advertisements to be the target of all advertisers, namely, the accurate delivery of the advertisements to target groups, target areas and target subjects, and the most suitable advertisements are spread to the most suitable audiences in the most suitable time and place, so that the maximum value of the advertisements is exerted.
Fig. 1 shows a schematic view of a delivery scene of a public transportation advertisement. When the public transport advertisement is put in, firstly, an advertiser is provided, and the requirement of the advertiser is to select k lines from a public transport network and put the advertisement in the buses with the k lines. When selecting an advertisement delivery route in a public transportation network, it is necessary to determine a plurality of factors related to an advertiser product based on the advertisement product itself, for example: the advertisement theme, the delivery area, the number of covered crowds and the like, when the advertisement delivery line is selected in the public transport network, the attribute of each public transport line needs to be considered, such as POI distribution around each public transport line, and the number of transfer people of the public transport line covered by the public transport line is far greater than that of the common public transport station because the number of transfer people of the public transport station is far greater than that of the common public transport station, so that the effect of delivering the advertisement to the public transport station is relatively good under the common condition.
The problem to be solved urgently is how to search the best advertisement delivery line in the urban public transportation network, wherein k lines are selected as the advertisement delivery lines in the public transportation network. Three challenges are involved with this problem:
1. the mass public transport network ensures that a solution space for selecting k lines from the mass public transport lines to carry out advertisement promotion is very large;
2. the passenger space-time mobility makes the bus line extraction unable to be carried out in isolation, and the comprehensive solution needs to be carried out by considering the time and space context; for example, on weekdays, a large number of passengers commute between residence and workplace, and by the end of the week, the commute start and end points become shopping and tourist attractions;
3. the attribute diversification of the lines, including the positions of the bus stops in the whole bus network, the administrative regions where the bus stops are located, the surrounding POI environments and the like are all factors influencing the advertising promotion effect.
At present, bus-mounted advertisement putting routes are mainly selected in the following three ways:
1. manually selecting a throwing line according to experience or a reference historical throwing scheme;
2. evaluating the number of passengers and the line length of all bus lines, and selecting the bus line with the most passenger data or the longest line;
3. and automatically extracting the optimal route from the public transport network by using a data mining method such as association rules and the like.
However, the adoption of the above mode to select the bus-mounted advertisement putting line has a common fault: the bus route is selected by taking the passenger volume as the only standard, however, the bus route and the passengers have respective characteristics which have space-time dynamic characteristics, and the characteristics are not captured and analyzed in the prior art, so that the advertisement cannot be spread to the most appropriate audience, and the advertisement putting effect cannot be guaranteed.
For example, some public transportation lines cover more business offices, some public transportation lines cover more tourist sites, and the audience of passengers on the two lines and their psychological state when taking a bus are different, and thus, the sensitivity and reverberation for different types of advertisements are also different. In addition, in each city, especially in large and medium-sized cities widely using bus body advertisement delivery, the bus routes are complicated, the method for manually selecting the delivery routes has low efficiency, poor expandability, scalability and operability, and the advertisement delivery effect cannot be estimated. That is, the traditional advertisement putting route selection method generally does not analyze the characteristics of the bus route and passengers and the space-time dynamic characteristics of the characteristics, so that the bus-mounted advertisement is difficult to exert the maximum effect.
In view of the above problem, an embodiment of the present invention provides a method for selecting a vehicle-mounted advertisement delivery bus route, fig. 2 is a flow diagram illustrating a method for selecting a vehicle-mounted advertisement delivery bus route according to an embodiment of the present invention, and as shown in fig. 2, the method for selecting a vehicle-mounted advertisement delivery bus route according to an embodiment of the present invention includes:
step S202, intelligent bus card data are obtained, and passenger track data are obtained based on the intelligent bus card data;
step S204, acquiring each bus line in the designated area and bus stations covered by each bus line;
in this step, the designated area may be a designated city (e.g., beijing city, shijiazhuang city, etc.), a designated province (e.g., hebei province, shandong province, etc.), a certain administrative area in the designated city (e.g., beijing hai lake area, beijing chaoyang district, etc.), etc., and the designated area is not specifically limited in the present invention.
Step S206, calculating the measured junction degree of each bus station as a transit station based on the passing bus station sequence of each passenger track in the passenger track data;
and S208, selecting one or more bus lines from the bus lines according to the hub degree of each bus station to launch vehicle-mounted advertisements.
According to the selection method of the vehicle-mounted advertisement delivery bus route, provided by the embodiment of the invention, the passenger track data can be obtained based on the intelligent bus card data, the junction degree of each bus station is calculated according to the bus station sequence of the passing of each passenger track in the passenger track data, and one or more bus routes are selected from each bus route according to the junction degree of each bus station to carry out vehicle-mounted advertisement delivery. The method is particularly suitable for advertisement putting scenes of widely spread scenes, namely, the advertisement putting scenes have no tendency of specific putting topics and regions. When the partial advertisement is put in, audiences do not need to be distinguished, and only the bus line is required to cover passengers as much as possible. The hub degree of the bus station refers to a measure of the bus station as a transit station. The more the number of buses at the station is, the larger the number of passengers is, the larger the junction degree is, and the passenger flow of the bus station can be measured. Based on the method provided by the embodiment of the invention, one or more bus lines are selected from the bus lines according to the hub degree of each bus station for vehicle-mounted advertisement delivery, so that the requirement of an advertiser on passenger flow can be met, and the advertisement delivery effect is further improved.
The data of the Smart Card Transaction (SCT) includes the record of each Card holder taking the bus. One record comprises a record of one-time taking of the card holder, and specifically comprises a bus card ID, a bus card type, record insertion time, a bus line ID, a bus ID, passenger boarding time, passenger disembarking time, a boarding station ID, a disembarking station ID and the like. The bus taking track of each passenger can be comprehensively obtained based on the intelligent bus card data, the bus taking tracks of the passengers are analyzed and summarized, the passenger tracks refer to the flowing tracks of the passengers in the bus, and the data records comprise the getting-on time, the getting-off time and the bus station passing sequence. And calculating the junction degree of each bus station based on each passenger track.
When bus routes are selected, one of the keys is to acquire passenger track data. Therefore, in a preferred embodiment of the present invention, when the intelligent bus card data is acquired and the passenger trajectory data is acquired based on the intelligent bus card data, the method may further include: acquiring intelligent bus card data comprising bus line numbers, getting-on and getting-off time and getting-on and getting-off station numbers; passenger trajectory data is obtained based on the smart bus card data.
Obtaining passenger trajectory data based on smart bus card data may further include:
firstly, recording the number of a passenger getting on or off a bus station in the intelligent bus card data as a station charging number;
secondly, calculating the logical serial number of the station where the passenger gets on or off the bus in the intelligent bus card data based on the time for the passenger to get on or off the bus and the charging serial number of the station where the passenger gets on or off the bus in the intelligent bus card data;
and finally, determining a passing station number sequence according to the logical numbers of the passengers for getting on and off the bus station in the intelligent bus card data to obtain passenger track data comprising a bus line number, the time for passengers to get on and off the bus and the passing station number sequence.
In life, the number of the station of getting on the bus and the number of the station of getting off the bus in the original data of the intelligent bus card are the charge number of the station, and the problem that a plurality of stations share one charge number exists. This numbering method may not allow accurate analysis of the traffic volume at each station, and thus, it is necessary to map the charging number of each station to an actual logical number.
Taking the determination of the logical number of the boarding station as an example, the logical number of the boarding station can be obtained through the following steps:
s1-1, sorting the intelligent bus card data on the same bus according to the passenger boarding time to obtain the sorted intelligent bus card data;
step S1-2, the sorted intelligent bus card data are grouped, and passengers in the sorted intelligent bus card data are divided into a group with the same charging number of the stations where passengers get on the bus;
s1-3, clustering each group of intelligent bus card data by using a clustering algorithm, and taking the obtained clustering number as the actual station number corresponding to the station charging number;
step S1-4, calculating the average value of the getting-on time according to the intelligent bus card data in each cluster;
and S1-5, sequencing the clusters according to the average boarding time, and determining the logical number of the boarding stations of the passengers of the intelligent bus card data in each cluster according to the sequencing.
Likewise, the logical number of the getting-off station may be acquired as follows:
s2-1, sorting the intelligent bus card data on the same bus according to the getting-off time of the passengers to obtain the sorted intelligent bus card data;
step S2-2, grouping the sequenced intelligent bus card data, and grouping the passengers in the sequenced intelligent bus card data into a group with the same charge number of the getting-off station;
s2-3, clustering each group of intelligent bus card data by using a clustering algorithm, and taking the obtained clustering number as the actual station number corresponding to the station charging number;
step S2-4, calculating the getting-off time average value aiming at the intelligent bus card data in each cluster;
and S2-5, sequencing the clusters according to the getting-off time average value, and determining the logical serial number of the passenger getting-off station of the intelligent bus card data in each cluster according to the sequencing.
Based on the method for acquiring the logical numbers of the stations for getting on and off the train, different logical numbers can be accurately distributed to each station, so that the track data of each passenger can be accurately acquired, and the passenger flow of each station can be accurately analyzed. When assigning the logic number, the logic number may be assigned according to the sequence of the arabic numerals, or assigned in other manners, which is not limited in the present invention.
Fig. 3 shows the serial numbers of the bus stations covered by the buses of the 510 beijing route, as shown in the figure, the serial numbers of the bus stations covered by the buses of the 510 beijing route and the corresponding stations are "duquambodong 1", "subway forest bridge station 4", "beijing garden north gate 4", "forest intersection north 5", "aolin spring district 5", "yilin jiayuan east gate 5", "south ditch mud river 6", and the like, and the serial numbers of "subway forest bridge station" and "beijing teacher north gate" in the SCT data are the same (both are 4). This numbering method may result in failure to accurately analyze the passenger flow volume of each station, and thus it is necessary to map the charging number of the station to an actual logical number.
The specific processing method of the getting-on station mapping in the SCT record comprises the following steps:
s3-1, sorting the SCT records on the same bus according to the getting-on time;
step S3-2, grouping according to the getting-on station number (here, the charging number) recorded by the SCT;
s3-3, clustering each group of SCT records by using a K-Means algorithm, wherein the clustering number K is the actual station number contained in the toll station with the corresponding number;
step S3-4, calculating the average getting-on time value according to the SCT records in each cluster;
s3-5, sorting the K clusters according to the average value of the boarding time;
and step S3-6, determining the logical number of the boarding station recorded by the SCT in each cluster according to the sequence.
The process of mapping the charging number of the station to the actual logical number may be: firstly, sequencing the intelligent bus card data on the same bus according to the passenger boarding time to obtain the sequenced intelligent bus card data.
And secondly, grouping the sorted intelligent bus card data, and grouping the passengers in the sorted intelligent bus card data into a group with the same charging number of the stations where the passengers get on. As in the beijing 510-route bus in fig. 3, "double quanbutong" may be divided into a first group, "subway forest bridge station" and "beijing opera north gate" may be divided into a second group, "south ditch mud river" may be divided into four groups, and the other stations shown may be divided into three groups.
And then clustering each group of intelligent bus card data by using a clustering algorithm, wherein the obtained clustering number is used as the actual station number corresponding to the station charging number. Here, the K-Means algorithm may be used to cluster each set of smart bus card data. Of course, other clustering algorithms may also be adopted, and this is not specifically limited in the embodiment of the present invention. For example, after the intelligent bus card data corresponding to the first group of stations "double quanburg dong" are clustered, the obtained clustering number is 1, and after the intelligent bus card data corresponding to the second group of stations "subway forest bridge station" and "Beijing teacher garden Beimen" are clustered, the obtained clustering number is 2.
And finally, calculating the average value of the getting-on time aiming at the intelligent bus card data in each cluster, sequencing the clusters according to the average value of the getting-on time, and determining the logical serial number of the passenger getting-on station of the intelligent bus card data in each cluster according to the sequencing. For example, the row with the smaller time-to-vehicle average value in each cluster is ranked in front of the row with the larger time-to-vehicle average value in the row with the smaller time-to-vehicle average value in the cluster. The logic numbers of the bus stations covered by the Beijing 510 road and the corresponding bus stations can be 'Shuangquanberg east 1', 'Metro Lin Cuoqiao station 2', 'Jingshi Yunyuan Beimen 3', 'Lin Jinguan Beijing 4', 'Aolin Chunshun district 5', 'Yilin Jiayumen Dongmen 6', 'Nangou mud river 7', and the like.
And similarly, mapping the getting-off station charging number in the SCT record into a logic number.
After the passenger trajectory data is obtained, the hub degree of each bus station can be calculated according to the passing bus station sequence of each passenger trajectory in the passenger trajectory data.
Optionally, stations with a distance less than 100m can be combined according to the longitude and latitude coordinates of the bus stations, so that the subsequent calculation time is saved, and the calculation efficiency is higher; and according to the information of the getting-on station, the getting-off station and the bus route station in the SCT record, the passing station sequence of the record can be obtained, and therefore the passenger track data can be obtained. Thus, each SCT record corresponds to one piece of passenger trajectory data.

step S5-2, excavating a sequence pattern, excavating a sequence with the length larger than n based on the passenger track data, wherein n can be self-defined, and 2 can be selected; counting the number of passenger tracks which are the same as each sequence as the weight of the sequence; all the sequence sets are marked as P (capital letter P), a certain sequence is marked as pattern (abbreviated as small letter P), and the weight value of the sequence P is marked as w (P); FIG. 5 shows that pattern1 includes bus stops S1, S2, S3; p2 includes bus stops 1, 2; p3 includes bus stops 8, 9; p4 includes bus stops 4, 2, 6; p5 includes bus stops 2, 3, 6;
step S5-3, merging the sequence modes; combining sequences containing the same station to obtain a connection mode network; the weight of the sequence from 1 to 2 is w1, the weight of the sequence from 2 to 1 is w2, the weight of the sequence from 2 to 6 is w4, the weight of the sequence from 4 to 2 is w4, the weight of the sequence from 2 to 3 is w1+ w5, and the weight of the sequence from 3 to 6 is w 5;

Meanwhile, the selected bus line can be deleted from the candidate line set, the passenger track covered by the bus line is added to the covered passenger track set and deleted from the candidate track set, so that the interference of the selected bus line is eliminated when the bus line is selected again, and the selection result is more accurate.
The above embodiment is explained in detail below by means of a preferred embodiment.

The embodiment provides a scheme for selecting an advertisement delivery bus route in an advertisement delivery scene under a widely spread scene. In addition, the method can also have a theme scene with a directional function, under the scene, the advertisement has obvious theme tendency, and if the advertisement can be spread aiming at corresponding audiences, the effect and the cost performance of the advertisement can be greatly improved. If the website advertisement is recruited, the advertisement is put on more bus lines passing through commercial and office areas.
When advertisement delivery is performed in a subject scene with a directional function, POI (Point of interest, user interest Point data) of each bus station needs to be analyzed. The user interest point data is information of public places in a designated area, such as schools, parks, restaurants, shopping malls, cinemas, 4s shops, office buildings, public buildings, communities and the like. One record contains information of a place, specifically including the name, address, latitude and longitude coordinates, description of the place, and the like.

Furthermore, the advertisement delivery scene can also be a targeted administrative region scene, and in such a scene, the advertisement has a remarkable administrative region tendency and needs to be spread only for the audience of the relevant region. For example, the advertisement of the market in the core urban area, the advertisement should be put on the public transportation line in the core urban area (not the suburban area).
When the administrative region attributes of each bus station are determined, the administrative division attributes of the bus station can be determined by means of a map Application Programming Interface (API) according to the longitude and latitude coordinates of the geographic position of the bus station.

The sequence of the steps in the above process is not specifically limited in the embodiments of the present invention.
The embodiment of the present invention exemplifies the above formula to calculate the weight of all passenger tracks to the bus route and the coverage of each bus route, but it should be noted that the technical solution protected by the present invention is not limited to the solution implemented by each formula listed above and in the description, and those skilled in the art can think that the technical solution of the present invention can still be implemented by reasonably changing, increasing and decreasing the proportion, adjusting the coefficient, increasing the weight, and the like, and these solutions that are not exhaustive are also within the scope of the present invention.
Of course, no matter which advertisement putting scene is aimed at, when at least one bus route is selected in each bus route according to the multidimensional attribute of the bus station, the putting requirements of the advertisement putting person need to be considered, such as the putting time range (specific to hours), the number of the bus routes (such as 2-3 routes, 4 routes and the like), the bus route length range (such as 5000 meters, 3000 meters and the like), the bus route passenger flow range and the like, so that at least one bus route is selected in each bus route according to the multidimensional attribute of the bus station by combining the putting requirements, and the advertisement putting bus route serving as the advertisement putting scene is recommended.
Referring to fig. 6, a process of selecting an advertisement delivery bus route aiming at different advertisement delivery scenes based on intelligent bus card data SCT, map data, and user interest point POI data according to an embodiment of the present invention will be described in general. In this embodiment, the multidimensional attributes of the bus stop include hub degree, administrative district affiliation, and function topic distribution, which respectively correspond to the hub degree, administrative district distribution, and function topic distribution of fig. 6.
The coverage scenario is maximized for a widely spread scenario, i.e., the passenger flow in fig. 6. Firstly, the track data of passengers are extracted according to the intelligent bus card data. And then, excavating the hub degree of the bus station by adopting a Temporal-Id eaGraph algorithm based on the passenger track data. The specific calculation process of the passenger trajectory data extraction and the bus station junction degree is referred to above. And then calculating the coverage of any bus line in the designated area by adopting the improved Max k-cover and combining the passenger track data, and selecting the bus line with the maximum coverage as an advertisement delivery bus line for selection. And finally, the selected bus routes are put into a scene with maximized coverage of the passenger flow. The specific algorithm of the bus route coverage is as described above.
The coverage scenario is maximized for targeted administrative areas scenarios, i.e., the target administrative areas in fig. 6. First, geographical location information of a bus stop, i.e., geographical coordinate mapping in fig. 6, is acquired according to map data. And then excavating the administrative area distribution of the bus station based on the geographical position information. And then calculating the coverage of any bus line in the designated area by adopting the improved Max k-cover and combining the passenger track data, and selecting the bus line with the maximum coverage as an advertisement delivery bus line for selection. And finally, the selected bus routes are put into a scene with maximized coverage of the target administrative area.
The coverage scenario is maximized for the directed function theme scenario where, i.e., the target function zone in fig. 6. First, POI data within a specified distance around the geographical location information of the bus stop, i.e., POI data in fig. 6, are collected from map data. After POIs data are obtained, topic modeling is achieved through a topic distribution model LDA, and functional topic distribution of each bus station is obtained. And then calculating the coverage of any bus line in the designated area by adopting the improved Max k-cover and combining the passenger track data, and selecting the bus line with the maximum coverage as an advertisement delivery bus line for selection. And finally, putting the selected bus route into a scene with the maximized coverage of the target function area.
After the vehicle-mounted advertisement public transportation delivery line meeting the demand of the advertiser is selected, the selected public transportation line can be evaluated based on the following three indexes.
1.Coverage
Coverage, audience Coverage, refers to the proportion of advertisement audiences in the target population, that is, the proportion of passenger tracks covered by the delivery routes in all passenger tracks, and the calculation formula is as follows:
wherein coverage is audience coverage of the advertisement, traj _ covered is passenger track set covered by advertisement delivery line, traj is all passenger track set, numtraj_coveredNumber of tracks in traj _ covered set, numtrajThe total number of passenger trajectories.
2.OTS
Ots (opportunities To see), which means the number of times each audience contacts the advertisement, and may be defined as the number of stations where the audience takes the bus on average in the bus advertisement, and the calculation formula is as follows:
where the OTS exposes the audience to advertisements times,for passenger's trackNumber of buses passing midway, numtraj_coveredAnd covering the number of the passenger tracks for advertising bus routes.
GRP (Gross Rating Points)
Grp (gross Rating points), gross evaluation, which is the sum of OTS percentage, is used to measure the influence of the advertisement, and in the bus body advertisement, the number of times that the advertisement is transmitted to the audience in 100 passenger tracks can be defined, and the calculation formula is as follows:
GRP=coverage×OTS×100
in addition, the invention designs two indexes aiming at the directional function theme scene and the directional administrative region scene respectively.
4.PTS
Pts (points To see), which means the number of the set subject area passed by each audience along the way, that is, the number of the preset subject area passed by each advertisement audience along the way when taking the bus is measured based on the characteristic attribute of statistics, wherein, the larger the value is, the more the advertisement spreading object meets the requirement of the advertisement subject.
5.T_GRP
T _ GRP (topic Gross points), functional topic Gross scores, similar to GRP, were used to evaluate the impact of the functional topic generated by the advertisement in 100 passenger tracks. The calculation formula is as follows, PTS represents the sensitivity of audience to advertisement, Coverage is advertisement Coverage, and T _ GRP calculated by the following formula can evaluate the influence of advertisement in 100 audiences.
T_GRP=PTS×Coverage×100
6.TDC
Tdc (targeted discharge coverage), which refers to the proportion of the trajectory covered by the dropped bus line passing through the target administrative area, wherein a larger value indicates a larger proportion of the dropped bus line covering the administrative area.
7.D_GRP
D _ GRP (discrete Gross Rating points), administrative Gross assessment, similar to GRP, for evaluating the impact of the administrative area generated by the advertisement in 100 passenger tracks, and the calculation formula is as follows. The TDC index is the proportion of the audience track covering the target administrative region, the OTS is the average number of times that the audience contacts the advertisement, and the influence of the advertisement on 100 audiences can be evaluated by the following formula.
D_GRP=TDC×OTS×100
In an embodiment of the invention, before measuring the delivery effect of the advertisement delivery route scheme of the bus body, the advertisement delivery route can be visually displayed, so that the advertisement delivery person can conveniently measure and adjust the advertisement delivery route. For example, if the advertisement delivery routes are all public transportation routes of a certain city, the advertisement delivery routes can be displayed on a map of the city. The specific display adjustment steps are as follows:
1) and visually displaying the route putting scheme, calling a map through a preset interface, newly building a layer on the map, and performing formatting division on the newly built layer, so that a grid result of the urban map is displayed in a grid mode. Meanwhile, the passenger flow volume of each grid is displayed in a heat map mode. In the newly-built layer, bus routes in the scheme are displayed in a linear graph mode, and grids along the way are filled with obvious marks (such as colors and symbols); by adopting the method, the area covered along the bus route, namely the area for advertisement propagation, can be visually displayed very intuitively;
in this step, when the newly-built map layer on the urban map is gridded, longitude and latitude information of the urban bus station and the bus route can be obtained first, the urban center coordinates and the advertisement delivery area are set, and the newly-built map layer on the map data is subjected to grid segmentation by taking 1km (or other distances) as a grid interval.
The statistical process of the passenger flow of each grid is as follows, in each time interval (each hour) of the whole day, the total number of the passengers getting on and off the bus at each bus station is calculated, and the number of the passengers with repeated bus card IDs is subtracted, so that the passenger flow of each bus station in the time interval is obtained. And calculating to obtain the passenger flow of each map grid all day according to the longitude and latitude information of the bus station and the passenger flow information of each bus station.
Certainly, the passenger flow of each bus line can also be calculated according to the method, for example, in each time period (each hour) of the whole day, the sum of the passenger flows of all bus stops where each bus line passes is calculated, and the passenger flow of each bus line in the time period is obtained by subtracting the repeated passenger number of the bus card ID.
2) The method comprises the following steps of carrying out statistics on bus line characteristics of an advertisement delivery line scheme, and carrying out statistics on all bus line characteristics in the current delivery line scheme, such as the number of bus lines, the length of the bus lines, the passenger flow, administrative divisions or functional subject areas, administrative divisions or functional subject area coverage areas and total area, so as to measure the advertisement delivery effect of the bus line scheme, wherein the measurement process refers to the above embodiment;
3) personalized adjustment is carried out on the advertisement delivery route scheme, if adjustment is needed, a new bus route can be freely added into the delivery scheme or the existing bus route can be removed through the newly-built layer according to the current bus route delivery scheme, a new delivery scheme is formed, and all bus route characteristics of the new delivery scheme are counted according to the step 2);
