Method, apparatus, and computer program product for verifying and/or updating road map geometry based on received probe data

An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and computer program code configured to, with the processor, cause the apparatus to at least:

• receive probe data from a plurality of probes within a region, wherein the probe data comprises at least one of heading information and location information for each probe data point;
• match the probe data to a link segment to generate map-matched probe data;
• calculate a difference between the at least one of heading information and location information of the map-matched probe data points and of the link segment;
• determine a statistical mean of the difference between the at least one of heading information and location information of the map-matched probe data points and the link segment;
• determine an error of the statistical mean of the difference between the at least one of heading information and location information of the map-matched probe data points and the link segment;
• and
• flag the link segment for manual review in response to the statistical mean of the difference between the at least one of heading information and location information of the map-matched probe data points and the link segment being greater than the error of the statistical mean multiplied by a biasing factor.
