Abstract

An algorithm was developed to provide traffic engineers a means to identify factors or combinations of factors that cause accident overrepresentation at a given highway location relative to some average. The output from this algorithm can be used for further site investigation to develop accident countermeasures that may be responsive to the problems at the site. It also provides quantitative measures of the degree of overrepresentation for each factor at that site. Available mainframe computer programs to facilitate the computation involved are given. An example of application of this algorithm to a highway location in Texas is described in full detail. Comparison of the output from this full algorithm with that from an automated microcomputer program developed at the Texas Transportation Institute is also discussed.
