A process was developed in the study to aid the District personnel of the Texas Department of Highways and Public Transportation (SDHPT) in their tasks of: identifying high accident locations on urban Interstate highways and urban non-Interstate freeways; analyzing accident causative factors associated with these high accident sites; and determining and evaluating appropriate remedial measures at these sites. A conceptual approach was first developed, which was then revised and improved based upon experience gained from field tests of 10 sites. An existing mainframe computer program, known as WINDOW, was modified to identify high accident locations and to create an analysis file for use with a Microcomputer Accident Analysis Program (MAAP). The MAAP program identifies accident characteristics at the high accident locations that are overrepresented when compared to the average for similar highway type in the same county. The program also has the capability to produce various tables and reports for detailed evaluation of the high accident locations.
