This paper describes a procedure for forecasting future trip productions and attractions by traffic analysis zones. Traffic analysis zones having characteristics related to trip production and trip attraction were grouped together. A trip generation rate was determined from base year data for each grouping of zones. The generation rate for a group having like characteristics was assumed to hold true for the forecast year. However, changes in the forecast of variables related to trip production and trip attraction can shift a particular zone from its original grouping or cell to another higher or lower trip generation rate group. /author/.
