Design Guidelines for At-Grade Intersections near Highway-Railroad GradeCrossings

摘要

The design of at-grade intersections near highway-railroad grade crossings ischallenging because of the interaction between the two geometric features. Their designs can have a critical effects on safety and operation at both features. These guidelines provide information helpful in the following specific areas: traffic control devices, signal interconnection, channelization, high-profile or 'hump' crossings, and illumination.
