IDENTIFICATION, QUANTIFICATION AND STRUCTURING OF TWO-LANE RURAL HIGHWAY SAFETY PROBLEMS AND SOLUTIONS. VOLUME I--TECHNICAL REPORT. FINAL REPORT

The purpose of the study was to identify safety problems on two-lane rural highways through the review and analyses of existing data and to determine the cost-effectiveness of possible highway-related solutions to those problems. An extensive review of literature was conducted and existing research data bases were analyzed to provide state-of-the-art information on the current safety performance of two-lane highways and the potential benefits of highway accident countermeasures. An important emphasis of this study was to provide some general guidance for investing highway safety expenditures on two-lane rural highways in future years, and to provide additional data and procedures to state and local highway engineers to enable them to select safety improvement projects more effectively. The study covers the entire two-lane rural system, consisting of over 3 million miles of highway, and includes the range of countermeasures which would ordinarily be considered for use on the system.
