The primary objective of this study is to develop models for analyzing vehicular traffic as one form of intercommunity linkage. Of particular concern are traffic linkage relationships that exist between Champaign-Urbana and communities located within a fourteen county area of East-Central Illinois. The models were structured from data obtained from a 1958 origin and destination study of the Champaign-Urbana metropolitan area. The techniques employed in analyzing these data are multiple regression and factor analysis. The basic gravity model was expanded for regional analysis by (1) assuming that a condition of competitive interaction exists among communities of a region and (2) by considering not only the total traffic flow among communities, but instead the ability of each to attract or produce trips. The independent variables included measures of community attractiveness (e.g., population, employment, sales, etc., and time distance in minutes). Various mathematical transformations (i.e., first, second, third powers and square roots) were assigned to each of the independent variables. The dependent variables were vehicle trips and person trips. The high degree of intercorrelation between them, however, indicated that it was not necessary that they be analyzed separately.
