Guide for Evaluating the Safety Performance of Shared Railway–Highway Interfaces

Safety issues exist at highway and rail crossings. However, safety concerns are not limited to crossing areas; they also exist in cases where one or more rail lines share at-grade roadway space with other roadway users, operating parallel along one side of the road, within the median, or within the roadway. These shared railway–highway interfaces include light rail (including streetcars) and heavy rail transporting passengers (intercity, commuter, and tourist lines) and freight within and adjacent to urban, suburban, and rural roads. These parallel and shared orientations create unique safety concerns that are not well-documented and do not have safety performance functions or crash modification factors to inform decision-making during project development. Research is needed to provide practitioners tools to evaluate the safety performance of shared railway-highway interfaces where the railroad track is within or immediately adjacent to the public roadway, including sidewalks, trails, medians, and shoulders. This research needs to consider all road users, including trains, other motorized vehicles, and nonmotorized users, (e.g., pedestrians or bicyclists.) The research objective is to develop a guide with a methodology, framework, and tools for evaluating the safety performance of shared railway-highway interfaces.
