Abstract

Federal highway safety standard 9 provides guidelines to traffic engineers in their identification and surveillance of accident locations. The state of Michigan developed a comprehensive, computerized system of accident inventory called the Michigan accident location index. This system required the coding and computing of the 192,000 km (120,000 miles) of roadway in the state. The procedure for computerizing the roadway network consisted of three tasks: data coding, data entry, and resolution of edit and cross-reference errors. The use of computer programs to assist in each of these tasks resulted in a methodology that proved to be a fast, accurate, and cost-effective approach.
