Detecting Road Condition Changes from Probe Data

An apparatus comprising:

• at least one processor;
• and
• at least one memory including computer program code for one or more programs;
• the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least perform:
• identifying a set of vehicle probe data associated with a roadway location;
• performing a comparison of the set of vehicle probe data to a baseline for the roadway location;
• dividing the set of vehicle probe data into a sparse subset and a regular subset, wherein the sparse subset includes abnormalities or corrupted values with respect to the baseline;
• and
• identifying an event at the roadway location based on vehicle probe data in the sparse subset.

A non-transitory computer-readable medium including instructions that when executed perform:

• identifying a set of vehicle probe data associated with a roadway location;
• performing a comparison of the set of vehicle probe data to a baseline for the roadway location;
• dividing the set of vehicle probe data into a sparse subset and a regular subset, wherein the sparse subset includes abnormalities or corrupted values with respect to the baseline;
• and
• identifying an incident at the roadway location based on vehicle probe data in the sparse subset.
