This is the fifth biennial Benchmarking Project which began in 2003. Researchers analyzed data from the 50 States and from 50 large and 18 small and midsized U.S. cities to document trends in bicycling and walking. This report uses case studies from around the U.S. to illustrate efforts taken to support bicycling and walking. This 2016 edition has been reformatted from previous editions.

Provides context on pedestrian safety issues, crash patterns and contributing factors, and resulting impacts that may help orient readers from diverse sectors—including advocates, roadway owners and operators, legislators and law makers, real estate developers, businesses and private industries, public health practitioners, researchers, educators, enforcement officers, and others—to identify shared concerns and opportunities to make a difference.
Multimodal transportation networks provide access to jobs, education, health care, recreation, transit, and other essential services in urban, suburban, and rural areas throughout the United States. Interconnected pedestrian and bicycle infrastructure makes walking and bicycling a viable transportation choice for everyone and this contributes to the health, equity, and quality of life of our communities. This publication is a resource for practitioners seeking to build multimodal transportation networks.
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.
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.
"In 1985, the FHWA designated 13 specific design elements as controlling criteria for roadway design (see Mitigation Strategies for Design Exceptions). The 13 controlling criteria are (1) design speed, (2) lane width, (3) shoulder width, (4) bridge width, (5) structural capacity, (6) horizontal alignment, (7) vertical alignment, (8) grade, (9) stopping sight distance, (10) cross slope, (11) superelevation, (12) vertical clearance, and (13) horizontal clearance.
