SIMPLIFIED PROCEDURE FOR ESTIMATING FUTURE TRIP GENERATION (ABRIDGMENT)

This procedure (which assumes that existing socioeconomic data are already completed) involves the following steps: develop the control total for the number of trip productions (P's) and attractions (A's) by purpose; add new developments by zone, that are known to be coming; divide the study area into developed area and undeveloped area; for developed areas, determine growth potential for each zone, adjust potential by using appropriate factors, and apply the factors directly to the existing P's and A's according to purpose; for undeveloped areas, flag zones that will be developed by target year according to percentage developed; apply average trip rate per developed unit according to purpose; add the total P's and A's compare with the control total, and adjust as necessary; and continue the distribution. The procedure makes the following asumptions: newly developed areas will be similar in characteristics to the typical existing developed areas, and the error in trip rates is probably less than that introduced by a zone-by-zone 20-year forecast.
