Rural Expressway Intersection Safety Toolbox Desktop Reference.

摘要

This document is intended to be a guide for planning-level decisions concerning safety issues and subsequent potential improvements at rural expressway intersections. It is NOT a design guide. It simply presents the gamut of safety treatment options and available strategies that have been employed in an attempt to reduce the number and severity of collisions at unsignalized rural expressway intersections. This document should only be used as a tool for considering safety treatment options at rural expressway intersections. It is meant to aid transportation agency management in selecting the most appropriate rural expressway treatment to address the particular safety issue they are facing. This document is a quick reference companion to the Rural Expressway Intersection Safety Toolbox. More details on each strategy can be found within the contents of that document. Treatment strategies have been categorized within 9 emphasis areas (A through I) similar to those within NCHRP 500, Volume 5 2; however, the focus here is directly on unsignalized rural expressway intersections rather than unsignalized intersections in general. Some strategies may qualify for multiple categories, but have been placed in the category judged to be the most applicable.
