Estimation of actual conditions of a roadway segment by weighting roadway condition data with the quality of the roadway condition 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:
• receive condition data for at least one path segment from a plurality of data sources;
• determine a hierarchy for the plurality of data sources;
• and
• estimate conditions on the at least one path segment based on the hierarchy for the plurality of data sources, wherein when data is available at a higher level of the hierarchy, the higher level supersedes a lower level of the hierarchy for the estimated conditions, and when data is unavailable at the higher level of the hierarchy, the lower level of the hierarchy is used for the estimated conditions.

A method comprising:

• Receiving, at input port, condition data for at least one path segment from a plurality of data sources;
• determining, by a processor, a hierarchy for the plurality of data sources;
• and
• calculating, by the processor, estimated conditions on the at least one path segment based on the hierarchy for the plurality of data sources, wherein when data is available at a point along the at least one path segment at a higher level of the hierarchy, the higher level supersedes a lower level of the hierarchy for the estimated conditions, and wherein when data is unavailable at the point along the at least one path segment at the higher level of the hierarchy, the lower level of the hierarchy is used for the estimated conditions.
