This is one of a series of six reports describing simplified aids to improve transportation decisions without resorting to computers or extensive data collection. An analytical aid is described which provides a method for deriving and using the variable of automobile availability per household. This is an important socioeconomic variable in travel demand estimation. It is frequently not available, however, at the level desired, e.g., transportation planning zone, traffic zone, or census block, or for the current year at any level. A strong correlation was found between auto availability per household and the average market price of homes and the percent of home ownership. Data for these two variables are generally more readily available at the block or zone level or may at least be forecast more precisely at this level than automobile availability. This report describes auto availability per household as a function of the product of the two variables. Estimates of automobile availability derived from this function can be applied to trip generation and modal split analysis in transit system studies, route patronage estimation, and sketch planning studies in urban areas of any size. Examples of trip generation and modal split applications of the variable are also presented.
