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.

First claim

What is claimed is:

1. An information processing device, comprising:
a central processing unit (CPU) configured to:
acquire, 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 one or the plurality of first vehicles and the content of the reference information;
analyze a road status in a predetermined region using the difference information related to the one or the plurality of first vehicles present in the predetermined region; and
detect a traffic congestion state of a road of the predetermined region,
wherein, when a proportion of first vehicles whose actual traveling speed is slower than a predetermined traveling speed included in the reference information to the one or the plurality of first vehicles present in the predetermined region is larger than a first predetermined threshold value, the CPU is configured to determine that the road of the predetermined region is in a traffic congestion state.

2. The information processing device according to claim 1 ,
wherein, when a number of the first vehicles whose actual traveling speed is slower than the predetermined traveling speed included in the reference information among the one or the plurality of first vehicles present in the predetermined region is larger than a second predetermined threshold value, it is determined that the road of the predetermined region is in the traffic congestion state.

3. The information processing device according to claim 1 ,
wherein, when a proportion of first vehicles whose actual arrival time is later than a predetermined arrival time included in the reference information to the one or the plurality of first vehicles present in the predetermined region is larger than a third predetermined threshold value, the CPU is configured to determine that the road of the predetermined region is in the traffic congestion state.

4. The information processing device according to claim 1 ,
wherein, when a number of first vehicles whose actual arrival time is later than a predetermined arrival time included in the reference information among the one or the plurality of first vehicles present in the predetermined region is larger than a fourth predetermined threshold value, the CPU is configured to determine that the road of the predetermined region is in the traffic congestion state.

5. The information processing device according to claim 3 ,
wherein, when a setting spot to which the predetermined arrival time is set is not present in the predetermined region, the CPU is configured to detect the 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.

6. The information processing device according to claim 1 ,
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 CPU is operable to detect a traffic congestion state in the automobile expressway and a traffic congestion state in the other road.

7. The information processing device according to claim 3 , wherein the CPU is configured to:
provide information of the road in the traffic congestion state to the one or the plurality of first vehicles, a second vehicle different from the one or the plurality of first vehicles, or a device that manages the one or the plurality of first vehicles,
provide information related to the predetermined region designated from an information provision destination or information related to the predetermined region and a neighboring region.

8. The information processing device according to claim 7 ,
wherein, when a current position and a destination are designated as the information related to the predetermined region, the CPU is configured to provide a route to bypass the road determined to be in the traffic congestion state as the information related to the predetermined region.

9. The information processing device according to claim 1 ,
wherein, when the road of the predetermined region is determined to be in the traffic congestion state, the CPU is configured to predict a cause of traffic congestion using the difference information.

10. The information processing device according to claim 1 ,
wherein the one or the plurality of first vehicles are vehicles belonging to a same type of business.

11. The information processing device according to claim 10 ,
wherein the one or the plurality of first vehicles are vehicles whose operation is controlled by the reference information.

12. The information processing device according to claim 11 ,
wherein the one or the plurality of first vehicles are vehicles of a public transportation system.

13. The information processing device according to claim 1 ,
wherein the CPU is configured to extract the road that is in the traffic congestion state for a time more than a predetermined time or the predetermined region including the road.

14. 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, wherein, when a proportion of first vehicles whose actual traveling speed is 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, a road of the predetermined region is determined to be in a traffic congestion state.

15. An information processing method, comprising:
in an information processing device comprising a central processing unit (CPU):
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 one or the plurality of first vehicles and the content of the reference information;
analyzing a road status in a predetermined region using the difference information related to the one or the plurality of first vehicles present in the predetermined region; and
determining that a road of the predetermined region is in a traffic congestion state when a proportion of first vehicles whose actual traveling speed is slower than a predetermined traveling speed included in the reference information to the one or the plurality of first vehicles present in the predetermined region is larger than a predetermined threshold value.

16. An information processing device, comprising:
a central processing unit (CPU) configured to:
acquire, 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
