INTERSTATE SAFETY IMPROVEMENT PROGRAM
The purpose of this report was to prepare prioritized rankings of recommended improvements which could be implemented for the Interstate Safety Improvement Program. Considerable detail is presented which documents analysis procedures used to determine sites, sections, and elements of the roadway in need of improvement. The average number of accidents per interchange, bridge, 1.0-mile (1.6-km) section, and 0.3-mile (0.48-km) spots were summarized for large urban, medium urban, and rural sections of the interstate system. At specified levels of statistical significance, critical numbers of accidents and critical accident rates were calculated to assist in identifying high-accident locations. A limited field inventory of the interstate system was conducted and the results are incorporated into the program. Dynamic programming was utilized as the means of developing prioritized rankings for safety improvements totaling approximately $27,500,000. Example budgets ranging from $5,000,000 to $30,000,000 are also presented.
