Methods and systems for generating parallel road data of a region utilized when performing navigational routing functions

A method for generating parallel road data of a region utilized when performing navigational routing functions, the method comprising:

• obtaining map data of the region over a network, wherein the map data comprises at least one road sign, and the map data is obtained from a geographic database, or the map data is based on information captured by user equipment;
• determining a plurality of first links associated with the at least one road sign, based on the map data of the region;
• determining a relative position of the at least one road sign with respect to each of the plurality of first links;
• determining one or more second links, based on the relative position of the at least one road sign with respect to each of the plurality of first links;
• generating the parallel road data of the region, based on the one or more second links;
• and
• updating the map data of the region in a map database, based on the generated parallel road data,
• wherein the updated map data of the region from the map database is utilized when performing navigational routing functions, and
• wherein the region comprises at least one of the plurality of first links and/or the plurality of second links.

A computer programmable product comprising a non-transitory computer readable medium having stored thereon computer executable instruction which when executed by one or more processors, cause the one or more processors to carry out operations for generating parallel road data of a region utilized when performing navigational routing functions, the operations comprising:

• obtaining map data of the region over a network, wherein the map data comprises at least one road sign, and the map data is obtained from a geographic database, or the map data is based on information captured by user equipment;
• determining a plurality of first links associated with the at least one road sign, based on the map data of the region;
• determining a relative position of the at least one road sign with respect to each of the plurality of first links;
• determining one or more second links, based on the relative position of the at least one road sign with respect to each of the plurality of first links;
• generating the parallel road data of the region, based on the one or more second links;
• and
• updating the map data of the region in a map database, based on the generated parallel road data,
• wherein the updated map data of the region from the map database is utilized when performing the navigational routing functions, and
• wherein the region comprises at least one of the plurality of first links and/or the plurality of second links.
