This project will (1) investigate a new method for clustering ATR data and (2) extend methods developed to make efficient use of short vehicle counts to the problem of estimating mean daily traffic for different vehicle classifications. The univariate time-series model developed in earlier work will be replaced by a multivariate time-series model, with the different classification counts being the components of the multivariate observation. Model fitting and validation will be done, factor groups developed, and then (a) a method for assigning short count sites to factor groups, and (b) a method for estimating mean daily traffic by vehicle classification will be tested.
