Hierarchical route generation, provision, and selection

1. A method comprising:

receiving sensor data of a vehicle at a localized server associated with a particular geographic region that has one or more roadway segments, the localized server and the vehicle being located in the particular geographic region;

analyzing, at the localized server, the sensor data to determine one or more of a localized lane option and a localized path option for navigating the vehicle;

providing the one or more of the localized lane option and the localized path option for navigating the vehicle to a centralized server executing a route planner, the centralized server having data covering a plurality of geographic regions and located remotely from the particular geographic region;

determining, at the centralized server, a centralized route option including the one or more of the localized lane option and the localized path option; and

providing the centralized route option including the one or more of the localized lane option and the localized path option to a guidance selector of a navigation application of the vehicle for processing.

2. The method of claim 1 , wherein the centralized route option includes the localized lane option and the localized path option.

3. The method of claim 1 , further comprising:

selecting at the vehicle to follow the centralized route option including the one or more of the localized lane option and the localized path option; and

providing turn-by-turn instructional guidance via the navigation application to a driver.

4. The method of claim 3 , further comprising:

severing a connection between the localized server from the vehicle responsive to the vehicle leaving the particular geographic region;

establishing a connection between a second localized server and the vehicle responsive to the vehicle entering a region associated with the second localized server; and

determining, by the second localized server using a second set of sensor data received from the vehicle, a new path option for the centralized route option.

5. The method of claim 4 , further comprising:

providing the new path option for the centralized route option for display in a graphical user interface;

receiving a selection to update the centralized route option to use the new path option; and

updating the centralized route option to use the new path option.

6. The method of claim 1 , wherein the localized server is an edge server.

7. The method of claim 1 , wherein the localized server is a roadside unit.

8. A method comprising:

receiving sensor data of a vehicle at a localized server associated with a particular geographic region that has one or more roadway segments, the localized server and the vehicle being located in the particular geographic region;

generating, at the localized server, one or more localized navigation routes using the sensor data of the vehicle;

generating, at a centralized server, one or more centralized navigation routes, the centralized server being distinct from the localized server and remotely located from the localized server and the particular geographic region;

providing the one or more localized navigation routes and the one or more centralized navigation routes to a guidance selector of a navigation application executing on board the vehicle; and

selecting, via the guidance selector, a particular route to follow.

9. The method of claim 8 , further comprising:

providing the one or more localized navigation routes and the one or more centralized navigation routes for display in a graphical user interface;

receiving a selection to follow the particular route; and

providing turn-by-turn instructional guidance via the navigation application to a driver.

10. The method of claim 8 , wherein the vehicle is an autonomous vehicle, and the method further comprises:

automatically determining that the particular route is a most efficient route to follow; and

controlling the vehicle using one or more actuators of the vehicle based on the particular route.

11. The method of claim 8 , further comprising:

responsive to the vehicle leaving the particular geographic region, changing to a second localized server associated with a second geographic region distinct from the particular geographic region; and

determining, by the second localized server using a second set of sensor data received from the vehicle, a new path option.

12. The method of claim 11 , further comprising:

providing the new path option for display in a graphical user interface;

receiving a selection to update the particular route to use the new path option; and

updating the particular route to use the new path option.

13. The method of claim 8 , wherein the localized server is an edge server.

14. The method of claim 8 , wherein the localized server is a roadside unit.

15. A system comprising:

one or more processors;

one or more memories storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:

receiving sensor data of a vehicle at a localized server associated with a particular geographic region that has one or more roadway segments, the localized server and the vehicle being located in the particular geographic region;

analyzing, at the localized server, the sensor data to determine one or more of a localized lane option and a localized path option for navigating the vehicle;

providing the one or more of the localized lane option and the localized path option for navigating the vehicle to a centralized server executing a route planner, the centralized server having data covering a plurality of geographic regions and located remotely from the particular geographic region;

determining, at the centralized server, a centralized route option including the one or more of the localized lane option and the localized path option; and

providing the centralized route option including the one or more of the localized lane option and the localized path option to a guidance selector of a navigation application of the vehicle for processing.

16. The system of claim 15 , wherein the centralized route option includes the localized lane option and the localized path option.

17. The system of claim 15 , wherein the operations further comprise:

selecting at the vehicle to follow the centralized route option including the one or more of the localized lane option and the localized path option; and

providing turn-by-turn instructional guidance via the navigation application to a driver.

18. The system of claim 17 , wherein the operations further comprise:

severing a connection between the localized server from the vehicle responsive to the vehicle leaving the particular geographic region;

establishing a connection between a second localized server and the vehicle responsive to the vehicle entering a region associated with the second localized server; and

determining, by the second localized server using a second set of sensor data received from the vehicle, a new path option for the centralized route option.

19. The system of claim 18 , wherein the operations further comprise:

providing the new path option for the centralized route option for display in a graphical user interface;

receiving a selection to update the centralized route option to use the new path option; and

updating the centralized route option to use the new path option.

20. The system of claim 15 , wherein the localized server is an edge server.
