Hierarchical Route Generation, Provision, and Selection

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 vehicle being located in the particular geographic region;
• generating, at the localized server, one or more localized navigation route options using the sensor data of the vehicle;
• generating, at a centralized server, one or more navigation route options, the centralized server being distinct from the localized server and remotely located from the localized server;
• providing the one or more localized navigation routes and the one or more centralized navigation routes to a guidance selector of the vehicle navigation application executing on board the vehicle;
• and
• selecting, via the guidance selector, a particular route to follow.

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 vehicle being located in the particular geographic region;
• analyzing 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 lane and the path for navigating the vehicle to a centralized server executing a route planer;
• the centralized server having data covering a plurality of geographic regions;
• determining a centralized route option including 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.
