In 1971 the Michigan Department of Transportation used the analytical tool SCREEN which provided tabular reports and an automated collision diagram. Its data sources were traffic volumes and accident reports. The Michigan Accident Location Index (MALI) was completed in 1979. The principal features of MALI are the common accident report form used by all state and local government agencies and the accident location system based on street intersections and street names. In an effort to upgrade its ability to locate highway segments with correctable accident patterns and widen its scope of analysis, a prototype model called the Michigan Dimensional Accident Surveillance (MIDAS) was developed for analyzing the state trunkline system (9000 miles). This involved non-labor-intensive procedures for predicting the expected impacts of incremental alterations. Details of the first generation model MIDAS-I are described. MIDAS-I offered an objective, accurate means of identifying significant accident patterns, independent of the magnitude of accidents or accident rate. MIDAS-II (also described) was developed to permit the evalaution of safety alternatives by predicting the expected number of accidents. Conclusions drawn from MIDAS II modeling experience are also discussed.
