Information corresponding to one or more traversable map elements (TMEs) within a zone of interest is accessed from the geographic database. A respective category of a plurality of categories is determined for each of the one or more TMEs based at least in part on the information corresponding to the TME. A first category encoding data structure is generated based at least in part on map version agnostic identifiers corresponding to TMEs determined to be in a first category of the plurality of categories, wherein the first category encoding data structure is a probabilistic data structure configured to not provide false negatives for TMEs within the zone of interest. The first category encoding data structure is provided such that a mobile apparatus receives the first category encoding data structure.

A mobile apparatus receives a route response including information identifying a starting location and a target location of a route and an encoding data structure encoding the route. The encoding data structure is a probabilistic data structure configured to not provide false negatives. The mobile apparatus uses the information identifying the starting and target locations to identify a decoded origin traversable map element (TME) and a decoded target TME of the mobile version of the digital map for the route; accesses map information for determining a cost value for TMEs of the digital map, wherein a TME that satisfies the encoding data structure is assigned a minimal cost value; determines a decoded route from the decoded starting TME to the decoded target TME based on the cost value assigned to the TMEs using a cost minimization route determination algorithm; and performs at least one navigation function using the decoded route.

A mobile apparatus receives a route response comprising an encoded route and one or more delay encoding data structures. The delay encoding data structures are probabilistic data structures configured to not provide false negatives. The mobile apparatus determines a decoded route based on the encoded route and a mobile version of a digital map; determines an expected traffic delay for at least one adjacent traversable map element (TME) of the decoded route based on the one or more delay encoding data structures; and performs one or more navigation functions based at least on the expected traffic delay for the at least one adjacent segment of the decoded route. An adjacent TME is a TME of the digital map that intersects the decoded route and is not a TME of the decoded route.

Implementations of the present disclosure are directed to systems and methods for reducing the size of packet headers by using a single field to encode multiple elements. Instead of including separate fields for each element, one or more encoded fields may be used, each of which is decoded to determine two or more values for the data packet. A receiving device decodes the encoded data field to retrieve the two or more values.

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.

A network apparatus determines a route from an origin TME to a target TME based on map data of a network version of a digital map. The route includes a list of route TMEs to be traveled from the origin TME to the target TME. The network apparatus accesses map version agnostic information identifying each TME of the list of route TMEs from the network version of the digital map; generates a map version agnostic identifier for each route TME of the list of route TMEs based on the accessed information; evaluates coding functions based at least on the map version agnostic identifier for each route TME to generate a coded identifier for each route TME; generates an encoding data structure based on the coded identifiers for the route TMEs; and provides the encoding data structure.

A first category encoding data structure encoding map version agnostic identifiers of traversable map elements (TMEs) within a zone of interest and associated with a first category is received. The first category encoding data structure was provided by a network apparatus. The first category encoding data structure is received by a mobile apparatus comprising a processor, memory storing a mobile version of a digital map, and a communication interface. The first category encoding data structure is a probabilistic data structure configured to not provide false negatives. The mobile apparatus determines a respective category associated with each of one or more TMEs within the zone of interest based at least in part on whether the TME satisfies the first category encoding data structure.
