Abstract: A method, apparatus and computer program product are provided to localize data from at least one of two or more data sets a based upon the registration of synthetic images representative of the two or more data sets. In the context of a method, first and second synthetic images are created from first and second data sets, respectively. In creating the first and second synthetic images, representations of one or more features from the first and second data sets are rasterized. The method also determines a transformation based upon a phase correlation between the first and second synthetic images. The transformation provides for improved localization of the data from at least one of the first or second data sets. The method also generates a report that defines the transformation.

Abstract: Method, systems, and devices are described for determining traffic volume of one or more path segments. A computing device may receive probe data associated with a road segment from one or more sources. The computing device selects either a free flow algorithm or a congestion algorithm for the probe data, and calculates an estimated probe quantity from historical data using either the free flow algorithm or the congestion algorithm. A traffic volume may be estimated from the estimate probe quantity.

Abstract: A time differential is estimated between a plurality of signals by determining a filter response of a first electrical signal with a first filter array, determining a filter response of a second electrical signal with a second filter array, and determining, based at least on the filter response of the first electrical signal and the filter response of the second electrical signal, a time differential between the first electrical signal and the second electrical signal. A first optical signal is converted into the first electrical signal and a second optical signal is converted into the second electrical signal. The filter response of the first electrical signal and the filter response of the second electrical signal are sampled and the time differential between the first electrical signal and the second electrical signal is determined based at least on the sampled filter response of the first electrical signal and the sampled filter response of the second electrical signal.
