A number of pedestrian treatments at railroad grade crossings have been developed and are used throughout the United States. The decision of when to use these treatments is generally a matter of best practices, using a decision tree, or conducting a site assessment. There has been little research on the efficacy of particular treatments. More important, because pedestrian treatments are seldom, if ever, used in isolation, there is no known research on what particular configurations of available pedestrian treatments provide the highest level of safety. A USDOT 2010 policy statement encourages transportation agencies to improve opportunities for pedestrian and bicyclists. The United States Access Board, in turn, has issued a Notice of Proposed Rulemaking to establish guidelines to address public right of way issues for people with disabilities. In anticipation of more non-motorized users of varying abilities making use of pedestrian grade-crossing facilities, it is important that the efficacy of pedestrian treatments at grade crossings be fully understood.
