FACTOR ANALYSIS OF SOCIO-ECONOMIC VARIABLES IN TRIP GENERATION MODELS

Factor analytic study of the body of data obtained from home interview surveys show that only a few factors adequately represent the meaning explained by several socio-economic variables normally utilised in the development of trip generation models. Study involving males and females of different occupational groupings and for various trip purposes has exhibited that there exist four basic traits identified as prosperity, stage in life cycle, facility for movement and location in the urban area explaining the meaning offered by various socio-economic indicators. Stepwise multiple regression analysis is performed on the same data to ascertain the variables that enter into the equations, and it is observed that there is a possibility for some of the correlated variables to enter into the final models. It is shown that when the independent variables are correlated with each other the factors present much more reliable and meaningful interpretation of the model formulation than normally possible through multiple regression techniques. /Author/TRRL/
