While estimate accuracy is the touchstone for many modeling choices and decisions, its determination is difficult. The difficulty is not technical but conceptual. In this chapter the accuracy of estimates is determined by simulation. The simulation code has been used to examine several issues: how estimate accuracy is affected by the addition of the Terrain variable, how the variance of AADT estimates influences estimate accuracies, and what is the effect on accuracy of using fewer years of data.
