Rural Expressway Intersection Safety Toolbox


Book Description

This document is intended to be a guide for planning-level decisions concerning safety issues and subsequent potential improvements at rural expressway intersections. It 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. 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.

Toolbox on Intersection Safety and Design


Book Description

This report presents an overview of principles and practices that will help readers develop intersection designs that achieve the highest levels of safety, mobility and cost-effectiveness. It demonstrates practical design measures and tools that will improve intersection safety, provides examples of effective applications, and discusses experiences with innovative solutions.










Rural Expressway Intersection Synthesis of Practice and Crash Analysis


Book Description

This report presents a national synthesis of rural expressway, two-way stop -controlled (TWSC) intersection safety strategies and intersection designs and an analysis of Iowa expressway TWSC intersection crash characteristics. A rural expressway is a multi-lane highway with a divided median and with mostly at -grade intersections, although some intersections may be grade separated. The synthesis of intersection strategies is conducted in two parts. The first is a literature review and the second part is a national survey of strategies currently being applied by state transportation agencies. The characterization of crash patterns at TWSC expressway intersections is examined through the analysis of 5 years of crash data at 644 intersections.




Roundabouts


Book Description

TRB's National Cooperative Highway Research Program (NCHRP) Report 672: Roundabouts: An Informational Guide - Second Edition explores the planning, design, construction, maintenance, and operation of roundabouts. The report also addresses issues that may be useful in helping to explain the trade-offs associated with roundabouts. This report updates the U.S. Federal Highway Administration's Roundabouts: An Informational Guide, based on experience gained in the United States since that guide was published in 2000.




Roadway Safety Tools for Local Agencies


Book Description

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 321: Roadway Safety Tools for Local Agencies examines the safety tools and procedures that are practical and relatively easy to apply, and that can be implemented by agencies with limited financial support and personnel. Recognizing the wide variation in the operations and responsibilities of local agencies, the report acknowledges that the level of expertise in transportation safety analysis also varies greatly.
