Estimation of Actual Conditions of a Roadway Segment by Weighting Roadway Condition Data With the Quality of the Roadway Condition Data

摘要

Actual conditions of a roadway segment are estimated by providing roadway condition data to a processor for the roadway segment from a plurality of different types of sources of the roadway condition data, assigning a quality to each of the plurality of different types of sources of the roadway condition data, and estimating in the processor the actual conditions of the roadway segment by using the roadway condition data and the quality of each of the plurality of different types of sources of the roadway data. The quality determines weightings given to each of the plurality of different types of sources.

1. 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 calculate 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 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.
