The flow chart 400 of the method for the position for managing user of a embodiment.In step 410, according to the vehicle reservation
History Order data in service obtain multiple origin informations of at least one historical user.
In this step, it in order to make the origin information of acquisition have more generality, can obtain using the vehicle preservation service
Whole users History Order data, alternatively, the History Order data of a part of user therein can also be obtained only.Example
Such as, it is assumed that when the initial period it is expected to be tested only for specific geographical area (for example, Chaoyang District, Beijing City), can only obtain
Take History Order data associated with the specific geographical area；In another example, it is assumed that it is attached to provide to be expected for particular group
When adding business, the History Order data of relevant user can also be only obtained.In this embodiment, origin information can be used
Family is sitting in the coordinate (for example, latitude and longitude coordinates) of position calling when vehicle reservation service.
At step 420, it for an origin information in the multiple origin information, determines and the origin information phase
Associated region.In this step, city map can be divided into multiple regions (for example, can be by entire Beijing in advance
Map be divided into multiple regions according to rectangular mode), and each region can have unique identifier.By judging
Coordinate in point information is located in the range of which region, to determine region associated with origin information.
In step 430, multiple geography information in the region are searched for.In the feelings for having determined the region residing for user
Under condition, need to search further for the geography information possible as Entrucking Point in the region.It should be noted that and in non-area
Any position all can serve as Entrucking Point.For example, the origin information of user may show that the user is located in certain park, so
And the vehicles such as taxi can not be travelled into inside park, thus geography information associated with the starting point is not at this time
It should be the address (for example, certain sight spot in park) for the actual position that user is currently located, and should be and the true geography
Position be associated (for example, closest) can be with the position (for example, at flat management) of ride-on vehicles.
In this step, since multiple History Orders may relate to multiple origin informations of multiple passengers, and each
It may search for multiple geography information in region, thus in step 440, the multiple geography information can be sorted to obtain
The list of candidate geography information.The purpose of sequence is, can find most popular address interested.Due to the popular journey of address
Degree reflects these addresses in the frequent degree being used by a user in the past to a certain extent, and speculates that user is more likely at this
It gets on the bus at a little hot topic addresses.For example, the associated geography information master of user that historical data is shown in certain park environs
It concentrates at the gate of all directions four in the park, then can speculate：The vehicle preservation service phase is used in future customer
Between, user more likely waits at the position at this four gates and getting on the bus.
Fig. 5 is hereinafter will refer to be described in detail how to determine region associated with the origin information.Fig. 5 is schematic
Show the schematic diagram 500 of geographic area according to one embodiment of the present invention.As shown in figure 5, city map can be according to
Pre-defined rule and be divided into multiple regions, can for example, according to the density of the different facilities such as road, building in different zones
City is divided into the identical or different region of size.
In an embodiment of the invention, entire Beijing can be divided into the identical square region of multiple sizes
Domain (2km × 2km), or can also be divided into 1.5km × 2km rectangular area (region as shown in Figure 5 510,520,
530、540).In an embodiment of the invention, can be smaller area by the intensive region division of intown facility
Domain (such as 2km × 2km), and by the more sparse region division of the facility in suburb be larger region (such as 3km ×
3km).Alternatively, city map can also be divided into other shapes by those skilled in the art according to the requirement of concrete application environment
The region of shape.
In an embodiment of the invention, the multiple geography information searched in the region include：Obtain the area
At least one characteristic point in domain；And the geography of multiple positions near the characteristic point in acquisition at least one characteristic point
