Perceived Environmental Utility Under Alternative Transportation Systems: A Framework for Analysis
This report is concerned with developing an analytical framework for examining residents' perception of their environmental utility under different transportation alternatives. A 3% sample of households in Sealy, Texas, was drawn for home interviews. Information was collected on 58 variables describing household socio-economic characteristics and travel habits. Four main clusters of households were delineated. INDSCAL analysis for each of the four groups produced three basic environmental dimensions and explains the maximum amount of variance in the input data. Additional analysis shows that the individuals within their group can vary on the importance which they attach to the different dimensions. The analysis reveals that the differential cognitions and evaluations of group members lead to interest groups whose support is drawn from different socio economic strata. Consequently, other kinds of interest groups which support or oppose transportation innovations are drawn from different socio-economic and activity groupings. The analytical framework of this report demonstrates how such interest groups are derived.
