LONG-RANGE TEMPORAL STABILITY OF TRIP GENERATION RATES BASED ON SELECTED CROSS-CLASSIFICATION MODELS IN THE DELAWARE VALLEY REGION

Results of a comparative trip generation rate analysis between a home interview survey conducted in the Delaware Valley region in 1987-1988 and the original 1960 survey are summarized. Selected stratification schemes based on combinations of trip purpose, family size, income, automobile ownership, and area type are tabulated and analyzed with cross-classification techniques to determine the impact of these input variables on the temporal stability of household trip generation rates. The selection of variables used in the cross-classification scheme affected the temporal stability of the resulting trip generation model. Household size stratifications were generally temporally unstable, income-based models more stable, and automobile ownership strata the most stable over time. A trip generation model based on appropriate cross-classifications by automobile ownership or area type, or both, produced reasonably stable trip generation results by trip purpose and when estimating total household travel.
