The objective of the research project was to develop procedures for identifying hazardous locations on all highway facilities except freeways and in the Central Business District (CBD). Both accident and non-accident measures, or indicators, are included in the formula proposed for establishing degree of hazardousness at spot locations within the highway system. The Users Manual describes and illustrates the procedure developed. A Hazardousness Rating Formula is presented which provides a means for arriving at a Hazardousness Index for any suspect site. The Formula incorporates data inputs for three accident indicators--number of accidents per year, accident rate (accidents per million entering vehicles), and accident severity; four objective non-accident indicators--sight distance, volume/capacity ratio, traffic conflicts, and erratic maneuver counts; and two subjective non-accident indicators--driver expectancy and information system deficiencies. Data requirements and collection procedures are defined, the necessary charts and computation forms are presented, and an illustrative example is provided.
