Abstract
The purpose of this paper was to prepare prioritized rankings of recommended improvements which could implemented for the Interstate Safety Improvement Program in Kentucky. 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, 1.6-km (1.0-mile) section, and 0.48-km (0.3-mile) 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. A user's guide for preparation of a safety improvement program was developed.
