Traffic-aware route encoding using a probabilistic encoding data

Abstract

A network apparatus determines a route from an origin traversable map element (TME) to a target TME. The route comprises a list of route TMEs to be traveled from the starting location to the target location. The network apparatus identifies adjacent TMEs to the route, wherein an adjacent TME is a TME of the digital map that intersects the route and is not a route TME; determines an expected traffic delay for each adjacent TME based on traffic data; separates the adjacent TMEs into a plurality of delay groups based on the corresponding expected traffic delays; generates delay encoding data structures; and provides the delay encoding data structures and information identifying the route. Each delay encoding data structure encodes a map version agnostic identifier for the adjacent TMEs of one of the delay groups and is a probabilistic data structure configured to not provide false negatives.
