Patent ID: 8805610

Claim:
A computer-implemented method for estimating annual average daily traffic for a first epoch for a first road segment comprising: providing historical traffic counts for the road segment from a short-term traffic counter from one or more historical epochs which predate the first epoch; providing data from a first permanent traffic counter; calculating one or more growth factors from the data of the first permanent traffic counter; applying the one or more growth factors to the historical short-term traffic counts and converting the historical traffic counts to traffic counts in the first epoch; converting the converted traffic counts in the first epoch to equivalent monthly average daily traffic values; using the equivalent monthly average daily traffic values to construct a first seasonal traffic pattern for the first road segment; finding a matching seasonal traffic pattern, derived from a second permanent traffic counter, to the seasonal traffic pattern of the short-term traffic counting site; and deriving by a computer, an annual average daily traffic value from the short-term traffic counter of the first epoch using one or more expansion factors from the second permanent traffic counter for the first road segment.
