Abstract: A system and method to facilitate the creation, organization, maintenance and determination of traversable routes for vehicles traveling between an origin and a destination. Traversable routes are based on one or a plurality of route segments each containing criteria related to physical aspects of the segment, including maximum allowable physical limits of a vehicle. These route segments may be partially or completely joined via standardized node identifiers prior to route selection to allow additional level(s) of physical or other criteria to be stored in association with a plurality of route segments. Individual route segments, collections thereof, or complete routes may be maintained independently, or in a hierarchical manner whereby physical criteria or other data exist in associated layers. Traversable routes may be determined by the selection of complete routes, which may contain one or a plurality of associated segments, and span certain origins and destinations.
