Abstract

Rural highway injury accident rates should theoretically increase with an increase in travel densities. Regression analyses of cross-sectional data on U.S. Primary and Secondary highways show a moderate positive association, but on the Interstate this association appears to be invariant. Fatal accident rates, on the other hand, are negatively associated with travel densities. Explanations for these results may be found in variables associated with travel densities, such as speed, speed variability, types of crash, and accessibility to emergency medical services. Changes in travel densities, between 1976 and 1979. on the major rural highway systems have been accommodated with no apparent effect on average accident rates.
