Abstract

Embodiments relate to assessing a road by acquiring, by a computing device comprising a processor, one or more images of at least a segment of a surface of the road, analyzing, by the computing device, the one or more images to determine a quality associated with the road, predicting, by the computing device, a change in the quality based on the analysis, and generating, by the computing device, a report comprising the predicted change in the quality.

Claims

1. A method for assessing a road comprising:

acquiring, by a computing device comprising a processor, one or more images of at least a segment of a surface of the road;

analyzing, by the computing device, the one or more images to determine a quality associated with the road;

predicting, by the computing device, a change in the quality based on the analysis; and

generating, by the computing device, a report comprising the predicted change in the quality.

2. The method of claim 1, further comprising:

segmenting, by the computing device, the road into a plurality of segments; and

analyzing, by the computing device, the one or more images based on the plurality of segments to determine a plurality of qualities associated with the corresponding plurality of segments.

3. The method of claim 1, wherein the one or more images are obtained by the computing device from at least one source, and wherein the at least one source comprises at least one of:

aerial photography, satellite image data, a fixed camera, and a moving camera.

4. The method of claim 1, wherein the report comprises a recommendation for a maintenance activity to be performed on the road based on the analysis of the one or more images and the predicted change in the quality.

5. The method of claim 1, where the one or more images comprises at least two images of the segment taken at different points in time, and wherein the analysis of the at least two images comprises determining a change in the quality of the surface of the road over the different points in time.

6. The method of claim 1, further comprising:

performing, by the computing device, filtering on the one or more images prior to the analysis of the one or more images in order to remove an extraneous feature from the one or more images.

7. The method of claim 1, further comprising:

receiving, by the computing device, user input regarding the report, wherein the user input is based on at least one of;

an acceptance of one or more maintenance activities recommended in the report,

a rejection of one or more maintenance activities recommended in the report,

a conditional acceptance of one or more maintenance activities recommended in the report subject to one or more modifications,

a user evaluation of the one or more images,

a user visit to the at least a segment, and

a prioritization of tasks associated with maintenance activities for the road; and

generating, by the computing device a maintenance output based on the report and the user input.

8. The method of claim 1, wherein the quality pertains to at least one of a pothole and rutting with respect to the road.

9. The method of claim 1, wherein the report comprises a predicted time until an unacceptable state in the road occurs, an identification of the importance of the road to a system or network, and a historical decision about maintenance from a problem to the road in the past.

10. A computer program product comprising:

a computer readable storage medium having program code embodied therewith, the program code executable by a processing device to;

acquire one or more images of at least a segment of a transportation network;

analyze the one or more images to determine a quality associated with the transportation network;

predict a change in the quality based on the analysis; and

generate a report comprising the predicted change in the quality.

11. The computer program product of claim 10, wherein the one or more images comprises a plurality of images taken from at least two perspectives, and wherein the program code is executable by the processing device to:

align the plurality of images onto an underlying feature set.

12. The computer program product of claim 10, wherein the one or more images comprises a plurality of images captured at different points in time, and wherein the program code is executable by the processing device to:

determine a change in the quality over the different points in time,

wherein the predicted change in the quality is based on the determined change in the quality over the different points in time.

13. The computer program product of claim 10, wherein the program code is executable by the processing device to:

analyze the one or more images using a static analysis to determine the quality associated with the transportation network.

14. The computer program product of claim 10, wherein the program code is executable by the processing device to:

apply a mathematical algorithm to the one or more images to obtain a feature set; and

classify the one or more images based on the feature set.

15. An apparatus comprising:

at least one processor; and

memory having instructions stored thereon that, when executed by the at least one processor, cause the apparatus to;

acquire one or more images of at least a segment of a transportation network;

analyze the one or more images to determine a quality associated with the transportation network;

predict a change in the quality based on the analysis; and

generate a report comprising the predicted change in the quality.

16. The apparatus of claim 15, wherein the one or more images are captured for a purpose other than use in connection with the transportation network.

17. The apparatus of claim 15, wherein the transportation network comprises a road.

18. The apparatus of claim 17, wherein the instructions, when executed by the at least one processor, cause the apparatus to:

perform a feature extraction on the one or more images to obtain at least one low-level quality associated with the road and at least one high-level quality associated with the road.

19. The apparatus of claim 15, wherein the instructions, when executed by the at least one processor, cause the apparatus to:

provide in the report a recommendation for a preventative maintenance activity to be performed on the transportation network based on the predicted change in the quality.

20. The apparatus of claim 19, wherein the recommendation comprises a suggested time frame for performing the preventative maintenance activity, and wherein the recommendation comprises a prioritized list of a plurality of recommended maintenance activities, and wherein the preventative maintenance activity is included in the list, and wherein the recommendation comprises an identification of at least one resource that is recommended to be used in performing the preventative maintenance activity.
