abstract="Median treatments are an important means of reducing accidents and delay on urban areterial highways. Five common median treatments are (a) two-way left-turn lane, (b) continuous left-turn lane, (c) alternating left-turn lane, (d) raised median divider with left-turn deceleration lanes, and (e) median barrier with no direct left-turn access. A benefit-cost comparison of these treatments that considers the accident reduction, delay reduction, and construction cost for median treatments installed in existing arterial highways is reported. The analysis is based on a literature review and reasonable assumptions regarding the effectiveness of the median treatments. The result of the benefit-cost analysis is a selection guide that can be used by a designer to determine the optimal median treatment for an arterial highway based on geometric and operational conditions.<p />",
