Abstract

The present disclosure is directed to methods and apparatus for providing directions to user devices that belong to pedestrians or to individuals traveling on pedestrian pathways. Pedestrians or other users of user devices wishing to travel along pedestrian pathways toward a destination may be provided instructions according to a criterion, a basic assumption, or a rule. While commonly such criteria may relate to providing individuals with directions to walk from a current location to a specified destination in a minimal time, methods and apparatus consistent with the present disclosure may also allow for a user to specify other rules or criteria that are consistent with one or more objectives or parameters specified by that user. To accomplish this, information may be received from user devices and instructions may be sent to those user devices as users of those user devices progress toward respective destinations.

Claims

1. A method for providing directions, the method comprising:

receiving information regarding a destination accessible via one or more pedestrian pathways;

identifying a starting location associated of a user device traversing the one or more pedestrian pathways toward the destination;

identifying a preferred one of the one or more pedestrian pathways toward the destination from the starting location, the preferred pathway identified based on a criterion and a first calculated time delay for crossing a first pedestrian street that intersects the preferred pathway;

providing a portion of an initial set of directions for proceeding along the preferred pathway toward the destination, wherein the portion of the initial set of directions is provided to the user device; and

identifying that a speed of movement of the user device is consistent with the criterion and the first calculated time delay for crossing the first pedestrian street, wherein a second portion of the initial set of directions is sent to the user device based on the identified speed being consistent with the criterion and the first calculated time delay.

2. The method of claim 1, further comprising:

performing a calculation that identifies an alternate time delay associated with an alternate route is less than a second time delay associated with the preferred pathway; and

updating a direction sent to the user device, the updated direction specifying the alternative route based on the alternate time delay being less than the second time delay.

3. The method of claim 1, further comprising:

receiving the starting location from the user device;

monitoring the movement of the user device to identify a change in distance and a change in time associated with the movement of the user device; and

calculating the speed of movement of the user device by dividing the change in distance by the change in time.

4. The method of claim 1, further comprising:

identifying a first total time delay associated with use of the preferred pathway toward the destination; and

identifying a second total time delay associated with use of an alternate pathway toward the destination, wherein identifying the preferred pathway is based on the first total time delay being less than the second total time delay.

5. The method of claim 1, wherein the criterion specifies selection of the preferred pathway based on minimizing estimated time delay.

6. The method of claim 1, further comprising:

receiving signal timing information from a monitoring device associated with the first pedestrian street crossing; and

identifying a projected arrival time and an estimated time when a walk designation display associated with the received signal timing is forecasted to be displayed at the first pedestrian street crossing, the projected arrival time associated with the speed of movement and the forecasted walk designation associated with the received signal timing.

7. The method of claim 6, further comprising identifying that a time difference in the projected arrival time and the estimated time is less that a threshold amount of time.

8. The method of claim 1, wherein the criterion is based on a user preference.

9. The method of claim 8, further comprising weighting the user preference more than a temporal component associated with the criterion.

10. A non-transitory computer-readable storage medium having embodied therein a program executable by a processor to perform a method for providing directions, the method comprising:

receiving information regarding a destination accessible via one or more pedestrian pathways;

identifying a starting location associated of a user device traversing the one or more pedestrian pathways toward the destination;

identifying a preferred one of the one or more pedestrian pathways toward the destination from the starting location, the preferred pathway identified based on a criterion and a first calculated time delay for crossing a first pedestrian street that intersects the preferred pathway;

providing a portion of an initial set of directions for proceeding along the preferred pathway toward the destination, wherein the portion of the initial set of directions is provided to the user device; and

identifying that a speed of movement of the user device is consistent with the criterion and the first calculated time delay for crossing the first pedestrian street, wherein a second portion of the initial set of directions is sent to the user device based on the identified speed being consistent with the criterion and the first calculated time delay.

11. The non-transitory computer-readable storage medium of claim 10, further comprising instructions executable to:

perform a calculation that identifies an alternate time delay associated with an alternate route is less than a second time delay associated with the preferred pathway; and

update a direction sent to the user device, the updated direction specifying the alternative route based on the alternate time delay being less than the second time delay.

12. The non-transitory computer-readable storage medium of claim 10, further comprising instructions executable to:

receive the starting location from the user device;

monitor the movement of the user device to identify a change in distance and a change in time associated with the movement of the user device; and

calculate the speed of movement of the user device by dividing the change in distance by the change in time.

13. The non-transitory computer-readable storage medium of claim 10, further comprising instructions executable to:

identify a first total time delay associated with use of the preferred pathway toward the destination; and

identify a second total time delay associated with use of an alternate pathway toward the destination, wherein identifying the preferred pathway is based on the first total time delay being less than the second total time delay.

14. The non-transitory computer-readable storage medium of claim 10, wherein the criterion specifies selection of the preferred pathway based on minimizing estimated time delay.

15. The non-transitory computer-readable storage medium of claim 10, further comprising instructions executable to:

receive signal timing information from a monitoring device associated with the first pedestrian street crossing; and

identify a projected arrival time and an estimated time when a walk designation display associated with the received signal timing is forecasted to be displayed at the first pedestrian street crossing, the projected arrival time associated with the speed of movement and the forecasted walk designation associated with the received signal timing.

16. The non-transitory computer-readable storage medium of claim 15, further comprising instructions executable to identify that a time difference in the projected arrival time and the estimated time is less that a threshold amount of time.

17. The non-transitory computer-readable storage medium of claim 10, wherein the criterion is based on a user preference.

18. The non-transitory computer-readable storage medium of claim 17, further comprising instructions executable to weight the user preference more than a temporal component associated with the criterion.

19. An apparatus for providing directions, the apparatus comprising:

a communication interface that receives information regarding a destination accessible via one or more pedestrian pathways; and

a processor that executes instructions store din memory, wherein execution of the instructions by the processor;

identifies a starting location associated of a user device traversing the one or more pedestrian pathways toward the destination;

identifies a preferred one of the one or more pedestrian pathways toward the destination from the starting location, the preferred pathway identified based on a criterion and a first calculated time delay for crossing a first pedestrian street that intersects the preferred pathway;

provides a portion of an initial set of directions for proceeding along the preferred pathway toward the destination, wherein the portion of the initial set of directions is provided to the user device; and

identifies that a speed of movement of the user device is consistent with the criterion and the first calculated time delay for crossing the first pedestrian street, wherein a second portion of the initial set of directions is sent to the user device based on the identified speed being consistent with the criterion and the first calculated time delay.

20. The apparatus of claim 19, wherein the processor executes further instructions to:
