Abstract

There is provided an information processing device including a difference information acquiring unit that acquires, for one or a plurality of first vehicles that travel according to a content of reference information including a predetermined traveling speed or arrival time, difference information representing a difference between an actual traveling speed or arrival time in each of the first vehicles and the content of the reference information, and a road status analyzing unit that analyzes a road status in a predetermined region using difference information related to the first vehicles present in the predetermined region.

Claims

1. An information processing device, comprising:

a difference information acquiring unit that acquires, for one or a plurality of first vehicles that travel according to a content of reference information including a predetermined traveling speed or arrival time, difference information representing a difference between an actual traveling speed or arrival time in each of the first vehicles and the content of the reference information; and

a road status analyzing unit that analyzes a road status in a predetermined region using difference information related to the first vehicles present in the predetermined region.

2. The information processing device according to claim 1,

wherein the road status analyzing unit analyzes the road status and detects a traffic congestion state of a road.

3. The information processing device according to claim 2,

wherein, when a proportion of first vehicles whose actual traveling speed is much slower than a predetermined traveling speed included in the reference information to the first vehicles present in the predetermined region is larger than a predetermined threshold value, the road status analyzing unit determines that a road of the predetermined region is in a traffic congestion state.

4. The information processing device according to claim 2,

wherein, when a number of first vehicles whose actual traveling speed is much slower than a predetermined traveling speed included in the reference information among the first vehicles present in the predetermined region is larger than a predetermined threshold value, it is determined that a road of the predetermined region is in a traffic congestion state.

5. The information processing device according to claim 2,

wherein, when a proportion of first vehicles whose actual arrival time is much later than a predetermined arrival time included in the reference information to the first vehicles present in the predetermined region is larger than a predetermined threshold value, the road status analyzing unit determines that a road of the predetermined region is in a traffic congestion state.

6. The information processing device according to claim 2,

wherein, when a number of first vehicles whose actual arrival time is much later than a predetermined arrival time included in the reference information among the first vehicles present in the predetermined region is larger than a predetermined threshold value, the road status analyzing unit determines that a road of the predetermined region is in a traffic congestion state.

7. The information processing device according to claim 5,

wherein, when a setting spot to which the predetermined arrival time is set is not present in the predetermined region, the road status analyzing unit detects a traffic congestion state of the road in the predetermined region using the actual arrival time at a closest setting spot before a vehicle enters the predetermined region or after the vehicle leaves the predetermined region.

8. The information processing device according to claim 3,

wherein the reference information is set to distinguish at least between an automobile expressway and another road, and

wherein, when the automobile expressway and the other road are present within the predetermined region, the road status analyzing unit detects a traffic congestion state in the automobile expressway and a traffic congestion state in the other road.

9. The information processing device according to claim 5, further comprising

an information providing unit that provides information of a road in a traffic congestion state to the first vehicles, a second vehicle different from the first vehicles, or a device that manages the first vehicles,

wherein the information providing unit provides information related to a predetermined region designated from an information provision destination or information related to the predetermined region and a neighboring region.

10. The information processing device according to claim 9,

wherein, when a current position and a destination are designated as the information related to the predetermined region, the information providing unit provides a route to bypass a road determined to be in a traffic congestion state as the information related to the predetermined region.

11. The information processing device according to claim 3,

wherein, when the road of the predetermined region is determined to be in a traffic congestion state, the road status analyzing unit predicts a cause of traffic congestion using the difference information.

12. The information processing device according to claim 1,

wherein the first vehicles are vehicles belonging to a same type of business.

13. The information processing device according to claim 12,

wherein the first vehicles are vehicles whose operation is controlled by the reference information.

14. The information processing device according to claim 13,

wherein the first vehicles are vehicles of a public transportation system.

15. The information processing device according to claim 3,

wherein the road status analyzing unit extracts a road that is in a traffic congestion state for a long time or a predetermined region including the road.

16. A terminal device, comprising:

a display unit that displays an analysis result of a road status in a predetermined region, which is analyzed using difference information related to first vehicles present within the predetermined region among pieces of difference information representing a difference between an actual traveling speed or arrival time in each first vehicle and a content of reference information, the pieces of difference information being acquired for one or a plurality of the first vehicles traveling according to the content of the reference information including a predetermined traveling speed or arrival time.

17. An information processing method, comprising:

acquiring, for one or a plurality of first vehicles that travel according to a content of reference information including a predetermined traveling speed or arrival time, difference information representing a difference between an actual traveling speed or arrival time in each of the first vehicles and the content of the reference information; and

analyzing a road status in a predetermined region using difference information related to the first vehicles present in the predetermined region.

18. A status display method, comprising:

displaying an analysis result of a road status in a predetermined region, which is analyzed using difference information related to first vehicles present within the predetermined region among pieces of difference information representing a difference between an actual traveling speed or arrival time in each first vehicle and a content of reference information, the pieces of difference information being acquired for one or a plurality of the first vehicles traveling according to the content of the reference information including a predetermined traveling speed or arrival time.
