This report contains the findings of research performed to quantify the safety and operational impacts of design element trade-offs and their associated risks. The report details the research performed and includes specific recommended crash prediction models and Accident Modification Factors (AMFs) for shoulder width and median width on rural four-lane roads.
Many agencies discourage access within the functional area of a signalized intersection, as recommended in current access management guidelines, which also suggests that unsignalized median openings be bidirectional openings designed for ...
