DENSITY AS A DETERMINANT OF HIGHWAY IMPACTS

The effects of superhighways in established residential areas in 23 standard metropolitan statistical areas in nine states are reported. Comparisons are made between affected and unaffected census tracts for 34 population and housing variables by using information from the U.S. Census for 1960 and 1970 and from state highway departments. The analysis tool is multiple regression, which permits statistical control for tract location and "history." Regressions were run separately for high-and low-density tracts, and housing density was posited as a conditioning factor of highway impact. Results indicate (a) substantial differences between affected and unaffected tracts in high-density tracts but not in the low-density stratum and (b) that despite these differences the highway impact variable accounts for little of the variance in the dependent variable. The latter finding implies that highways are of minor importance in explaining changes in census characteristics compared with general demographic trends and deliberate policies in metroplitan areas. /Author/
