Claim 0:
1. A computer-implemented method for automatically detecting a merge lane traffic jam comprising:
determining, by a processor, a plurality of road links in proximity to a merge point comprising a highway and a ramp connecting to the highway;
processing probe data collected from the plurality of road links to classify the plurality of road links, one or more sublinks of the plurality of road links, or a combination thereof into at least one of a highway upstream class, a merging area class, a highway downstream class, a ramp downstream class, and a ramp upstream class;
determining real-time vehicle speed data for the highway upstream class, the merging area class, the highway downstream class, the ramp downstream class, the ramp upstream class, or a combination thereof;
automatically determining an occurrence of the merge lane traffic jam based on the vehicle speed data; and
initiating a presentation of a merge lane traffic jam message on a device traveling on the plurality of road links or the one or more sublinks that are in the highway upstream class.
