9.11: A Policy on Geometric Design of Highways and Streets, 6th Edition

A Policy on Geometric Design of Highways and Streets, 6th Edition, 2011, commonly referred to as the “Green Book,” contains the current design research and practices for highway and street geometric design. The document provides guidance to highway engineers and designers who strive to make unique design solutions that meet the needs of highway users while maintaining the integrity of the environment. It is also intended as a comprehensive reference manual to assist in administrative, planning, and educational efforts pertaining to design formulation.

Pg 63-71: Bicycle Road Safety Audit Guidelines and Prompts Lists

Road Safety Audits (RSAs) are a formal safety examination of an existing or future roadway or off-road facility and are conducted by an independent, experienced, multidisciplinary team. The purpose of the Bicycle Road Safety Audit Guidelines and Prompt Lists is to provide transportation agencies and RSA teams with a better understanding of the safety of cyclists in the transportation system when conducting an RSA. These Guidelines present the RSA team with an overview of basic principles of the safety of cyclists and potential issues affecting cyclists.

Pg 15-1 to 15-11: NCHRP Report 600: Human Factors Guidelines for Road Systems

TRB’s National Cooperative Highway Research Program (NCHRP) Report 600: Human Factors Guidelines for Road Systems: Second Edition provides data and insights of the extent to which road users’ needs, capabilities, and limitations are influenced by the effects of age, visual demands, cognition, and influence of expectancies. NCHRP Report 600 provides guidance for roadway location elements and traffic engineering elements. The report also provides tutorials on special design topics, an index, and a glossary of technical terms.

Pg 91-104: Urban Bikeway Design Guide

The purpose of the NACTO Urban Bikeway Design Guide (part of the Cities for Cycling initiative) is to provide cities with state-of-the-practice solutions that can help create complete streets that are safe and enjoyable for bicyclists. The NACTO Urban Bikeway Design Guide is based on the experience of the best cycling cities in the world. The designs in this document were developed by cities for cities, since unique urban streets require innovative solutions.

Pg 125-136: Urban Street Design Guide

A blueprint for designing 21st century streets, the Guide unveils the toolbox and the tactics cities use to make streets safer, more livable, and more economically vibrant. The Guide outlines both a clear vision for complete streets and a basic road map for how to bring them to fruition.

Pg 623-629: Traffic Control Devices Handbook

The Handbook augments the 2009 Edition of the Manual on Uniform Traffic Control Devices (MUTCD). The Traffic Control Devices Handbook, 2nd Edition provides guidance and information to implement the provisions of the MUTCD. The objective of the Handbook is to bridge the gap between the MUTCD requirements and field applications. Additional guidance is provided on the new MUTCD requirements to clarify these MUTCD provisions. The Handbook does not establish policy, procedures, or standards for an agency, or set the "standard-of-care" for decisions on traffic control devices.

Search: Speed Hump: Crash Modification Factors Clearinghouse

A crash modification factor (CMF) is a multiplicative factor used to compute the expected number of crashes after implementing a given countermeasure at a specific site. The Crash Modification Factors Clearinghouse houses a Web-based database of CMFs along with supporting documentation to help transportation engineers identify the most appropriate countermeasure for their safety needs. Using this site, you can search to find CMFs or submit your own CMFs to be included in the clearinghouse.
