When a user end, namely a passenger end, sends a service request, namely the passenger end logs in a vehicle service system, as shown in fig. 3, a vehicle platform server generally recommends departure place information for the user, namely the 'middle customs SOHO building' in fig. 3 is the departure place information recommended for the user, when the passenger end sends an order according to the departure place information, the passenger end needs to go to the departure place position corresponding to the departure place information for taking a bus, the driver end can go to the departure place position according to the departure place information for driving, the accuracy of the departure place information is related to whether the passenger can quickly find the departure place position and whether the driver end can quickly find the passenger, so that the reasonable and accurate determination of the departure place information of the passenger is very critical, reference will now be made to specific embodiments.
As shown in fig. 4, the departure location information determining method provided in the embodiment of the present application may be applied to a vehicle platform server, and includes the following specific steps S401 to S403:
s401, after receiving a service request of a user side, acquiring information of a point of interest (POI) within a set range of a current geographical position distance from the user side; the information of each POI includes a POI name and POI characteristic information.
The user side may be referred to as a service request side, and specifically, the user side in the traveling field may be a passenger side, and specifically, the user side may include a mobile phone or a fixed phone or other devices with an information transmission function used by a passenger in a riding environment, such as a smart phone, a Personal Digital Assistant (PDA), a tablet computer, a notebook computer, a vehicle-mounted computer (carputer), a handheld game console, smart glasses, a smart watch, a wearable device, a virtual display device, or a display enhancement device, and the like, which is not limited herein.
After the passenger terminal logs in the vehicle service system, a service request may be sent to the vehicle platform server, where the service request may be used to request the vehicle platform server to push departure location information to the passenger terminal, and specifically, the service request of the passenger terminal may carry current geographic location information, which may specifically include longitude and latitude information where the passenger terminal is currently located.
After receiving a service request of a user side, the vehicle platform server first determines whether there is information about a point of interest (POI) near the current geographic position of the user side, for example, whether there is information about a POI within a set range of a distance from the current geographic position of a passenger side, and if so, acquires information about all POIs within the set range of the distance from the current geographic position of the user side.
Further, after obtaining the information of all the POI, the information of the POI unsuitable for participating in the determination of the departure point information is deleted, for example, some information representing linear POI on the map, such as "north four-loop west road", and information representing planar POI on the map, such as "beijing zoo", "olympic forest park", and the like, and some sensitive POI, such as "parking lot entrance and exit", "toilet", and the like, are deleted, so that the information representing point POI, such as "beijing zoo metro station", is obtained.
Specifically, the obtained information of the POI may include a POI name and POI feature information, and the POI name may include a point location name on an electronic map such as a mall name, a bus stop name, a subway stop name, and the like; the POI feature information herein may specifically include at least one of the following:
paying attention to the heat; historical order volume; the distance between the current geographic position of the user side and the current geographic position of the user side; the type to which the POI belongs.
The four POI features are only a specific embodiment, and may not be limited to the four POI features, and may further include other POI features, which are not described herein again.
The attention degree of the POI can be determined by acquiring history data, for example, the number of times that a POI is searched in a set history period can be obtained from the history data, and the attention degree can be defined by the number of times, and the higher the number of times of searching, the higher the corresponding attention degree.
The historical data can be obtained from historical order quantity or other search software, and the more times a certain name is searched, the more familiar the name is to the user, the higher the corresponding attention popularity of the name is, for example, some famous scenic spots, famous shopping buildings and some popular transportation hubs, such as "beijing university siemens", "zhongguan village shopping buildings", "beijing west station-subway station", etc., the more times the name of the hot spot is searched.
The historical order quantity of the POI refers to the historical order quantity taking the POI as a departure place or a destination, for example, in the same historical period, if the number of times of occurrence of the "beijing zoo subway station" in the historical order is 1000 times, and the number of times of occurrence of the "zhongguancun subway station" is 2000 times, the historical order quantity corresponding to the "beijing zoo subway station" in the historical period is 1000 times, and the historical order quantity corresponding to the "zhongguancun subway station" in the historical period is 2000 times.
The distance between the POI and the current geographic position of the user side refers to the distance between the longitude and latitude of the POI and the current longitude and latitude of the user side.
The POI belonging type may refer to an attribute type of POI previously classified according to the type of landmark building, such as a transportation hub, an office building, a business building, and the like.
S402, selecting a POI name from the POI names according to the POI characteristic information of each POI.
If there is information about a plurality of POIs in the vicinity of the current geographical location of the user terminal, a most suitable POI name needs to be selected from the POI names.
The feature information includes feature information of various categories, such as the above-mentioned attention degree, historical order amount, distance to the current geographical location of the user end, and types of POIs, and if there are multiple POIs in a set range of distance from the current geographical location of the user end, a POI name is selected from the POI names according to the feature information of each POI, as shown in fig. 5, the method specifically includes the following steps S501 to S502:
s501, determining the POI value of each POI according to the effectiveness value corresponding to each feature information in the information of each POI and the weight of each feature information.
The validity score here may be used to represent a contribution value of a feature of the POI to a corresponding POI selected as an actual departure point, and a weight of each feature information is used to represent an importance degree of the feature information type in all feature information types, and specifically, for a certain POI, the POI score of the POI may be obtained by performing weighted summation on the validity score corresponding to each feature information in the information of the POI.
Specifically, the validity score corresponding to each feature information in the information of each POI may be determined according to a mapping relationship between pre-stored feature information and validity score, for example, a mapping relationship between attention heat and validity score, a mapping relationship between historical order quantity and validity score, a mapping relationship between a distance between the POI and a current geographic location of the user and the validity score, and a mapping relationship between a type to which the POI belongs and the validity score are determined in advance.
Specifically, the mapping relationship between the attention popularity and the effectiveness score is determined according to the following process:
the number of times that the POI names of all POIs in a certain area (i.e., an area where the current geographical location of the user terminal is located) are searched can be counted, a score corresponding to the POI name with the highest searched number of times is set as a highest score, for example, 100 scores, and scores corresponding to the searched times of other POI names can be calculated according to the score corresponding to the POI name with the highest searched number of times, so that the mapping relationship between the attention heat and the validity score is determined.
The determination process of the mapping relation between the historical order quantity and the effectiveness score is as follows:
counting the times that the POI names of all POIs in a certain area are used as departure place information or destination information in a historical order, setting the score corresponding to the POI name with the highest historical order quantity as the highest score, such as 100 scores, and calculating the scores corresponding to the historical order quantities of other POI names according to the score corresponding to the POI name with the highest historical order quantity, so as to determine the mapping relation between the historical order quantity and the effectiveness score.
The determination process of the mapping relation between the distance between the POI and the current geographic position of the user side and the effectiveness score is as follows:
here, the validity score corresponding to each distance range may be determined in advance, for example, 100 scores corresponding to within 100 meters, 90 scores corresponding to greater than 100 meters and less than 300 meters, 80 scores corresponding to greater than 300 meters and less than 500 meters, and the like, so that the mapping relationship between the distance between the POI and the current geographic location of the user end and the validity score may be determined.
The determination process of the mapping relation between the type of the POI and the effectiveness score is as follows:
the corresponding score is determined according to the heat of the type of the POI, wherein the heat refers to the number of potential user ends corresponding to a certain type, for example, through historical data, if the number of potential user ends of the POI in the transportation junction station type is larger, the corresponding score is higher; the number of potential user ends of the POI in the mall class is also large, the corresponding score is also high, and the number of potential user ends of the POI in the office building class is small, the corresponding score is also low, and specifically, the mapping relationship between the type of the POI and the validity score may be determined according to the idea of determining the mapping relationship between the attention heat and the validity score, which is not described herein again.
After the effectiveness score corresponding to each kind of feature information in the information of each POI is determined, the POI score of each POI can be determined according to the following formula (1) according to the preset weight of each kind of feature information:
Figure BDA0002039169650000121
wherein, FmExpressing the POI value within the set range of the distance between the mth POI and the current geographic position of the user side, namely before calculating the POI value of each POI, randomly ordering the POIs, for example, 3 POIs, respectively ordering the POIs into the 1 st POI, the 2 nd POI and the 3 rd POI; a. theiRepresenting the effectiveness score corresponding to the characteristic information of the ith category in the POI characteristic information; w is aiRepresenting the weight corresponding to the feature information of the ith category in the POI feature information; n represents the number of categories of the POI feature information, such as the above-mentioned 4 categories, which are attention heat degrees, respectively; historical order volume; the distance from the current geographic position of the user end and the type of the POI.
For the above-mentioned 1 st POI, 2 nd POI and 3 rd POI, the following is a specific example to illustrate how to determine their POI scores:
for example, the effectiveness score corresponding to the attention heat degree in the feature information of the 1 st POI is 80 scores, the effectiveness score corresponding to the historical order quantity is 75 scores, the effectiveness score corresponding to the distance between the current geographical positions of the user side is 70 scores, and the effectiveness score corresponding to the type to which the POI belongs is 65 scores, where the weight of the attention heat degree is 30%, the weight corresponding to the historical order quantity is 30%, the weight corresponding to the distance between the current geographical positions of the user side is 20%, and the weight corresponding to the type to which the POI belongs is 20%, according to the above formula (1), the POI score of the 1 st POI can be determined to be 73.5 scores, and in the same manner, the POI score of the 2 nd POI is determined to be 65 scores, and the POI score of the 3 rd POI is determined to be 60 scores.
In the above process of determining the POI score, a case that the POI feature information includes four categories of POI features at the same time is considered, that is, a case that the POI feature information includes the attention degree, the historical order amount, the distance from the current geographic location of the user end and the type of the POI, and if the POI feature information includes only one of the categories, that is, n in the above formula (1) is equal to 1, the POI score of each POI may be determined directly according to the validity score corresponding to the unique feature information in the information of each POI, that is, the validity score corresponding to the feature information in the information of each POI is directly used as the POI score corresponding to the POI.
And S502, selecting the POI name of the POI with the highest corresponding POI score from the POI names of the information of the POIs.
Through the above formula (1), the POI score of each POI may be calculated, and the POI name of the POI with the highest POI score is selected, for example, the POI score of the 1 st POI is the highest in the above example, that is, the POI name of the 1 st POI is selected, for example, the POI name of the 1 st POI is "tommy park subway station", and then the selected POI name is "tommy park subway station".
The above process is that information of a plurality of POIs exists near the current geographical position of the user side, the POI name needs to be selected based on the POI score of each POI, and if only information of one POI exists near the current geographical position of the user side, the unique POI name of the POI is directly used as a selection object, and the subsequent departure location information determination process is continued.
The POI name of the POI with the highest POI score value is selected to participate in the subsequent determination process of the departure place information by simultaneously referring to the attention heat, the historical order quantity, the distance between the POI and the current geographic position of the user side and the type of the POI, so that the accuracy of the departure place information can be greatly improved, the passenger side and the driver side can find the POI conveniently, and convenience is provided for the passenger side and the driver side.
And S403, determining the departure place information of the user side according to the selected POI name and the current geographic position of the user side.
Determining the origin information of the user side, not only considering the selected POI name, but also considering a relationship between the selected POI name and the current geographic location of the user side, specifically as follows:
in one embodiment, the step S403 determines the departure location information of the user terminal according to the selected POI name and the current geographic location of the user terminal, and as shown in fig. 6, includes the following steps S601 to S605:
s601, judging whether a road is arranged between the current geographic position of the user side and the geographic position of the POI corresponding to the selected POI name.
Here, it is determined whether a road is located between the geographic position of the POI corresponding to the selected POI name and the current geographic position of the user side, for example, if the current geographic position of the user side is located on the north side of a road "qinghua west road" in which the user side is going, and the geographic position of the POI corresponding to the selected POI name is located on the south side of the road "qinghua west road", it is determined that a road is located between the geographic position of the POI corresponding to the selected POI name and the current geographic position of the user side, and if the geographic position of the POI corresponding to the selected POI name and the current geographic position of the user side are both located on the south side or the north side of the "qinghua west road", it is determined that no road is located between the geographic position of the POI corresponding to the selected POI name and the current geographic position of the user side.
And S602, if the judgment result is yes, determining that the departure place information comprises a POI name and indication information indicating that the departure place is opposite to the POI name.
If it is determined that a road exists between the geographical position of the POI corresponding to the selected POI name and the current geographical position of the user side, it is determined that the departure location information includes the POI name and indication information indicating that the departure location is opposite to the POI name, and as described above, it may be determined that the departure location information includes "tambour subway station" and "tambour subway station opposite side", or directly use the POI name + the "opposite side" as the boarding place name, that is, it may use the "tambour subway station opposite side" as the boarding place name.
And S603, if the judgment result is negative, judging whether the distance between the current geographic position of the user side and the geographic position of the POI corresponding to the selected POI name is larger than a first set distance.
If it is determined that there is no road between the geographical position of the POI corresponding to the selected POI name and the current geographical position of the user side, it is necessary to continuously determine whether the distance between the current geographical position of the user side and the geographical position of the POI corresponding to the selected POI name is greater than a first set distance.
The specific numerical value of the first set distance may be counted according to historical order data, for example, it is found through a large amount of historical order data that when the distance between the departure place and the current geographic position of the user terminal is about x meters, it is easier for the user to find the departure place, and the first set distance may be x meters; or may be determined by the recognizable distance of the human eye to the vehicle, that is, the distance at which most users can recognize a specific vehicle may be used as the first set distance, or other ways may be included, and are not limited herein.
And S604, if the distance is larger than the first set distance, determining that the departure place information comprises the area information of the POI corresponding to the selected POI name.
If it is determined that the distance between the current geographic position of the user terminal and the geographic position of the POI corresponding to the selected POI name is greater than the first set distance, it is determined that the departure location information includes area information where the POI corresponding to the selected POI name is located, for example, the departure location information includes information near a circular and transparent garden subway station, or the first set distance may be added with a name to more accurately represent the departure location information, for example, when the first set distance is 50 meters, the departure location information may be defined as information including an area 50 meters near the circular and transparent garden subway station, and the user terminal may use the area 50 meters near the circular and transparent garden subway station as a boarding place.
And S605, if the judgment result is negative, determining that the departure place information comprises the selected POI name.
If it is determined that the distance between the current geographic position of the user side and the geographic position of the POI corresponding to the selected POI name is not greater than the first set distance, the POI name can be directly used as departure place information, such as 'fairyland subway station'.
The above is a determination process of the departure location information performed when the information of the point of interest POI exists near the current geographic location of the user terminal, but when the current geographic location of the user terminal is in a non-luxurious area, it is possible that the information of the point of interest POI does not exist near the current geographic location of the user terminal, and the departure location information needs to be determined according to another way, which will be described in detail below.
In one embodiment, as shown in fig. 7, the method for determining departure point information further includes the following steps S701 to S702:
and S701, if the POI information does not exist in the set range of the distance from the current geographic position of the user side, acquiring road information of which the distance from the current geographic position of the user side is less than a second set distance.
The second set distance is simply distinguished from the first set distance, and there is no order of magnitude, and the road information may include a road name and a road location.
And S702, determining departure place information of the user side based on the road information and the current geographic position of the user side.
After acquiring the road information of which the current geographic position is less than the second set distance from the user terminal, determining the departure place information of the user terminal according to the position relationship between the acquired road information and the current geographic position of the user terminal, which is specifically as follows:
in one embodiment, if the road information includes a plurality of road names, the determining the departure location information of the user terminal based on the road names and the current geographic location of the user terminal in step S702, as shown in fig. 8, specifically includes the following steps S801 to S804:
s801, judging whether the current geographic position of the user side is located in the intersection position area of different roads or not based on the road information and the current geographic position of the user side.
And determining whether the road is crossed according to the road position in the road information, determining a crossed position area if the road is crossed, and judging whether the current geographic position of the user side is located in the crossed position area.
The specific reference of the cross location area here may be an intersection or a t-junction, the specific location area of the cross location area may be determined by pre-collected road data, or the specific location area of the cross location area may be determined by a location relationship of a road in an electronic map, and then whether the current geographic location of the user end is located in the cross location area of different roads is determined according to a relationship between the current geographic location of the user end and the specific location area of the cross location area, and the specific determination process of the specific location area of the cross location area is not described herein again.
And S802, if yes, determining that the departure place information comprises road names of different roads and information indicating that the current geographic position of the user side is located at intersections of the different roads.
For example, if it is determined that the current geographical position of the user terminal is located in the intersection position area of the "four-ring western road" and the "academic road", the starting place information is determined to include the names of the two roads, namely the "four-ring western road" and the "academic road", and the indication is that the two roads are located at the intersection of the "four-ring western road" and the "academic road", and specifically, the intersection of the "four-ring western road and the academic road" can be directly used as the starting place of the user terminal.
And S803, if the current geographic position of the user terminal is not located in the intersection position area of different roads, determining the vertical distance between the current geographic position of the user terminal and each road based on the current geographic position and road information of the user terminal.
If the current geographic position of the user end is not located in the intersection position area of different roads, the user end can be determined to be closest to which road by calculating the vertical distance between the current geographic position of the user end and each road, and then the subsequent departure place information determination process is carried out.
Specifically, the current geographic location of the user end is not located in a crossing location area of different roads, and includes:
there is no intersection of different roads, for example, although there are multiple roads, these roads are parallel.
Or, if there is a crossing of different roads, a specific location area of the crossing location area may be determined, but the current geographic location of the user terminal is located outside the specific location area of the crossing location area.
S804, determining that the departure location information includes the road name of the road with the shortest vertical distance from the current geographic location of the user end.
According to the method, after the road with the shortest vertical distance to the current geographic position of the user end is determined, the road name of the road is used as the departure place information of the user end, specifically, in order to facilitate the user end to find out a specific boarding place, the departure place information can include the direction information of the road, for example, when the current geographic position of the user end is determined to be close to the east of a small road A in an east-west trend, the east of the X road A can be used as the departure place information of the user end.
The above process is a case where the road information near the current geographic location of the user end includes a plurality of road names, and if the road information includes only one road name of one road, the departure location information of the user end is determined directly by the unique road name of the road, and similarly, in order to facilitate the user end to find a specific boarding location, the departure location information may include direction information of the road, such as the aforementioned "east of the X-way a").
Referring to fig. 9, the method for determining origin information provided by the present application is described as a specific example:
after a service request of a user side is received, acquiring the current longitude and latitude of the user side, then acquiring a POI list of 100 meters (within a set range) around the longitude and latitude, wherein the POI list comprises POI information, then judging whether the POI list is empty, if not, after filtering off the line POI, the plane POI and the sensitive POI, continuously judging whether the POI list is empty, if the POI list is still not empty, determining POI scores of the POI by using the characteristic information of the POI, selecting the POI with the highest score, continuously judging whether the selected POI and the current longitude and latitude of the user side cross a road, and if so, directly using the POI name plus face of the POI as a boarding place name of the user side; if the selected POI and the current longitude and latitude of the user side do not cross the road, continuously judging whether the distance between the selected POI and the current longitude and latitude of the user side is greater than 50 meters (a first set distance), if so, using the POI name + 'nearby' of the POI as the boarding place name of the user side; and if the distance between the selected POI and the current longitude and latitude of the user side is judged to be not more than 50 m, directly using the POI name of the POI as the boarding place name of the user side.
In addition, if the obtained POI list is empty, or the obtained POI list is not empty, but after filtering off the line POI, the face POI and the sensitive POI and the POI list is empty, obtaining a road list within 200 meters (a second set distance) around the current longitude and latitude of the user side, then judging whether the current longitude and latitude of the user side is at the intersection position of a plurality of roads, if so, using 2 roads + "intersection" of the plurality of roads as the place name of getting on the bus, and if not, using the road name of the road closest to the current longitude and latitude of the user side as the place name of getting on the bus.
And finally, after determining the departure place information of the user side, namely the boarding place name of the user side, pushing the departure place information to the user side to wait for confirmation of the user side.
