Correlating instrumented car responses with certain geometric elements of highways and accidents utilizing short section analysis. Paper presented at the 52nd Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1973.

An analysis procedure for determining the significant changes in instrumented car responses on adjacent short highway sections in order to correlate the sections with highway geometry elements, intersections and grades, and number of accidents, is presented. Using data from US-70 North Carolina, highest correlations between accidents and those significant change sections whose car responses were speed change, running time, and total time, were shown. It was also found that significant driver responses did not correlate highly with intersections or grades.
