Decisions involving statewide land use and transportation policies and programs require consistent information concerning the expected impact of these actions on the pattern and density of development and travel demand. The Statewide Activity Allocation Model (SAAM) is one of a set of analytical tools which has been developed for the Federal Highway Administration to provide this state information.

The SAAM is a Lowry-type model which has a unique residential mobility concept and provides information on population and employment by analysis area and forecast year. The model has been calibrated and subjected to a sensitivity testing procedure for a 141 zone system in Connecticut. The results of the calibration and sensitivity test indicate that the SAAM may be useful in evaluating the impact of alternative transportation and land use policies at the state level.
