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.

Claims

1. A method executed by a computer, the method comprising:

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.

2. The method according to claim 1, wherein

the outputting includes outputting, by the processor, the information representing the position on the basis of the occurrence spot, the traveling direction and also a traveling speed of the vehicle.

3. The method according to claim 1, wherein

the information representing the position is a node identifier for identifying a first node from among a plurality of node identifiers for respectively identifying a plurality of nodes that are included in a numerical map.

4. The method according to claim 3, wherein

the numerical map further includes information representing a spot of each of the plurality of nodes, and

the first node is a node whose spot is within a prescribed distance from the position.

5. The method according to claim 4, executed by the computer, the method further comprising:

determining, by the processor, a node that is within the 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 at least one vehicle including the vehicle and the plurality of incidents being the incident of the sudden stepping on the brake and determined on the basis of 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 occurrence times of the plurality of incidents from among a plurality of links included in the numerical map; and

associating, by the processor, anode and a link that were determined for each of the plurality of incidents so as to output the node the link.

6. The method according to claim 5, the method further comprising

outputting, by the processor, a number of pairs between which nodes match each other and links match each other from among a plurality of pairs of nodes and links output for each of the plurality of incidents, in the associating and outputting of the node and the link.

7. The method according to claim 6, the method further comprising:

calculating, by the processor, a distance between an occurrence spot of the incident and a node that is within the prescribed distance from a position of a spot that is ahead, in a traveling direction of the at least one vehicle at an occurrence time of the incident, of an occurrence spot of the incident, for each of the plurality of incidents, and

outputting, by the processor, a representative value that represents the plurality of distances calculated for nodes of pairs between which the nodes match each other and the links match each other.

8. A non-transitory computer-readable recording medium having stored therein a program for causing a computer to execute a process, the process comprising:

outputting 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.

9. An information processing apparatus comprising:

a processor that

outputs 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.
