Abstract
Variations in travel time, distance, and speed are identified for four Standard Metropolitan Statistical Areas. The unit of analysis consists of the journey-to-work for household heads. These variations are related to various socioeconomic, locational, density, and modal factors. A statistical framework consisting of the general linear model approach is used. This consists of a regression approach to analysis of variance designs. Both univariate and multivariate models are estimated to examine the variations in travel time, distance, and speed for the journey-to-work. The results consist of parameter estimates for each of the univariate models which are used for both hypothesis testing among factor levels and prediction; and graphs of the variation in the means of the different factor levels. Seven variables and associated two-way interactions are significant in explaining variation in the three travel measures. The absence of income as a significant explanatory variable or factor is a notable result.
