The usefulness of the family life-cycle concept in trip-generation procedures is examined. A life-cycle classification scheme is constructed after consideration of important components and data availability. The Automatic Interaction Detector program is used to determine which variables are important in affecting the number of trips taken by a household. These variables are then calculated in light of published census tract information. The stages in the classification scheme are designed to be compatible with census categories, thus ensuring the usefulness of the scheme. Trip-generation tables based on stage in the life cycle and vehicle ownership are developed by using data from the 1973 Niagara Frontier Transportation Committee home-interview survey. These tables are compared with trip-generation tables based on household size and vehicle ownership. Analysis of variance is used to compare the life-cycle-based scheme and the household-size-based scheme. The applicability and replicability of the lifecycle-based trip-generation tables are also tested by using data from the 1974 Rochester, New York, home-interview survey. Results indicate that the life-cycle-based trip-generation procedure produces accurate results and has several advantages over other procedures. An example of an application at the town level in Albany County is briefly described.
