There is an increasing need for a methodology which will provide quick and inexpensive forecasts of inputs from a variety of alternative transportation plans. QUADATT II (Quick And Dirty Analysis Techniques for Transportation — Version II) is a set of simplified models which has been compiled in order to fulfill this need.

The QUADATT II procedure was applied for this analysis to thirty transportation zones in the metropolitan area of Roanoke, Virginia. Five transit configurations were designed as input to QUADATT II, and the resultant impacts were evaluated. Based on the results of this application it was determined that QUADATT II provides reasonable trends in activity distributions and transportation characteristics related to a given set of alternative transportation plans, and does so at a much reduced level of cost and time over that of the typical large scale studies.
