US Patent 11682295 Adjusting historical probe data for new road geometry

An apparatus receives instances of probe data each comprising location data. The apparatus identifies instances of probe data corresponding to a first traversable map element (TME) of a current map version based on the location data and the current map version. The apparatus determines a current traffic measure for the first TME based on the probe data. The apparatus determines a historical traffic measure corresponding to a second TME of a previous map version that corresponds to the first TME of the current map version and a scaling factor for the first and second TMEs. The apparatus determines a scaled historical traffic measure by applying the scaling factor to the historical traffic measure and compares the current traffic measure and the scaled historical traffic measure. Responsive to determining that the comparison does not satisfy a similarity threshold requirement, the apparatus generates updated map/traffic data for the first TME.
