1. A method executed by a computer, the method comprising:
- determining, by a processor and from among a plurality of nodes included in a numerical map, a node that is within a prescribed distance from a position of a spot that is ahead, in a traveling direction of at least one vehicle at occurrence times of a plurality of incidents, of occurrence spots of the plurality of incidents, for each of the plurality of incidents, the plurality of incidents being an incident of a sudden stepping on a brake, respectively, and determined based on acceleration and a position measured by a sensor provided to the at least one vehicle;
determining, by the processor, a link in which the at least one vehicle was traveling at the occurrence times of the plurality of incidents from among a plurality of links included in the numerical map; and
associating, by the processor, a node and a link that were determined for each of the plurality of incidents so as to output the node the link.

Abstract
A method executed by a computer includes outputting, by a processor, information representing a position of a spot that is ahead, in a traveling direction of a vehicle, of an occurrence spot on the basis of a position of the occurrence spot and the traveling direction of the vehicle at an occurrence time of an incident of a sudden stepping on a brake, the occurrence spot being of the incident of the sudden stepping on the brake and the position of the occurrence spot and the traveling direction of the vehicle having been determined on the basis of acceleration and a position measured by a sensor provided to the vehicle.

5. A non-transitory computer-readable recording medium having stored therein a program for causing a computer to execute a process, the process comprising:
-
determining from among a plurality of nodes included in a numerical map, a node that is within a prescribed distance from a position of a spot that is ahead, in a traveling direction of at least one vehicle at occurrence times of a plurality of incidents, of occurrence spots of the plurality of incidents, for each of the plurality of incidents, the plurality of incidents being an incident of a sudden stepping on a brake, respectively, and determined based on acceleration and a position measured by a sensor provided to the at least one vehicle; determining, by the processor, a link in which the at least one vehicle was traveling at the occurrence times of the plurality of incidents from among a plurality of links included in the numerical map; and associating, by the processor, a node and a link that were determined for each of the plurality of incidents so as to output the node the link.

6. An information processing apparatus comprising:
-
a processor that determining from among a plurality of nodes included in a numerical map, a node that is within a prescribed distance from a position of a spot that is ahead, in a traveling direction of at least one vehicle at occurrence times of a plurality of incidents, of occurrence spots of the plurality of incidents, for each of the plurality of incidents, the plurality of incidents being an incident of a sudden stepping on a brake, respectively, and determined based on acceleration and a position measured by a sensor provided to the at least one vehicle; determining, by the processor, a link in which the at least one vehicle was traveling at the occurrence times of the plurality of incidents from among a plurality of links included in the numerical map; and associating, by the processor, a node and a link that were determined for each of the plurality of incidents so as to output the node the link.
