Abstract:

This report provides guidance for highway agencies to address the types of sight distance restrictions that are most likely to be encountered on specific roadway types. The guidelines identify design situations that address the relative cost of removing the sight restriction and the likely implications for safety of allowing the sight distance restriction to remain. When a decision is reached not to remove a sight restriction, the guidelines include a catalog of mitigation strategies for consideration in specific design situations on specific roadway types. Individual chapters address: design criteria for horizontal sight obstructions (HSOs); relationship of sight distance to crash frequency and severity; benefit-cost analysis; reliability analysis model for horizontal curves with limited stopping sight distance; assessing removal or mitigation of HSOs; and design exceptions and mitigation strategies.
