Geographic space management
First Claim
1. A system comprising:
- a plurality of subsystems operable to respectively manage maps of a plurality of regions obtained by dividing a geographic space including a route on which a moving object moves; and
a receiving section that receives an observation position of the moving object, whereinat least one subsystem among the plurality of subsystems includes;
a managing section operable to manage individual event information for events occurring in a management target region of the at least one subsystem among the plurality of regions and adjacent event information for events occurring in a partial range from a boundary of the management target region among routes in an adjacent region that is adjacent to the management target region, wherein the managing section is further operable to select events while prioritizing events occurring within the partial range from each of a plurality of intersection locations where each of the routes intersects with the boundary of the management target region, and manage the selected events as the adjacent event information, and wherein the managing section is further operable to select events while prioritizing events occurring within a range from each of the intersection locations that can be reached within a threshold time, and manage the selected events as the adjacent event information, wherein selecting events while prioritizing events decreases the number of repetitions of an event search; and
an event selecting section operable to select events about which the moving object is to be informed, from the individual event information and the adjacent event information managed by the at least one subsystem.

Abstract
At least one subsystem among the plurality of subsystems includes a managing section operable to manage individual event information for events occurring in a management target region of the at least one subsystem among the plurality of regions and adjacent event information for events occurring in a partial range from a boundary of the management target region among routes in an adjacent region that is adjacent to the management target region, and an event selecting section operable to select events about which the moving object is to be informed, from the individual event information and the adjacent event information managed by the at least one subsystem. Also provided is a method and computer program product.

5. A method comprising:
-
managing, with a plurality of subsystems of a server, maps of a plurality of regions obtained by dividing a geographic space including a route on which a moving object moves; and receiving an observation position of the moving object, wherein managing with the plurality of subsystems of the server includes; managing individual event information for events occurring in a management target region of a subsystem among the plurality of regions and adjacent event information for events occurring in a partial range from a boundary of the management target region among routes in an adjacent region that is adjacent to the management target region, wherein the managing includes selecting events while prioritizing events occurring within the partial range from each of a plurality of intersection locations where each of the routes intersects with the boundary of the management target region, and manage the selected events as the adjacent event information, and wherein the managing includes selecting events while prioritizing events occurring within a range from each of the intersection locations that can be reached within a threshold time, and manage the selected events as the adjacent event information, wherein selecting events while prioritizing events decreases the number of repetitions of an event search; and selecting events about which the moving object is to be informed, from the individual event information and the adjacent event information managed by the at least one subsystem. - View Dependent Claims (6, 7)

8. A computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform operations comprising:
-
managing, with a plurality of subsystems, maps of a plurality of regions obtained by dividing a geographic space, wherein the managing includes selecting events while prioritizing events occurring within the partial range from each of a plurality of intersection locations where each of the routes intersects with the boundary of the management target region, and manage the selected events as the adjacent event information, and wherein the managing includes selecting events while prioritizing events occurring within a range from each of the intersection locations that can be reached within a threshold time, and manage the selected events as the adjacent event information; and receiving an observation position of a moving object that moves on a route in the geographic space, wherein managing with the plurality of subsystems includes; managing individual event information for events occurring in a management target region of the at least one subsystem among the plurality of regions and adjacent event information for events occurring in a partial range from a boundary of the management target region among routes in an adjacent region that is adjacent to the management target region; and selecting events about which the moving object is to be informed, from the individual event information and the adjacent event information managed by the at least one subsystem, wherein selecting events while prioritizing events decreases the number of repetitions of an event search. - View Dependent Claims (9, 10)
