Pg 50-53: NHCRP Report 766 Recommended Bicycle Lane Widths for Various Roadway Characteristics

TRB’s National Cooperative Highway Research Program (NCHRP) Report 766: Recommended Bicycle Lane Widths for Various Roadway Characteristics presents an analysis of the research and design guidance for bicycle lane widths on existing travel lane widths and parking lane widths. The conclusions are most applicable to urban and suburban roadways with level grade and a posted speed limit of 30 mph and should be used cautiously for the design of roadways with motor vehicle speeds outside of the range of 25 to 35 mph, and in particular for higher-speed roadways.

Pg 1-6: Pursuing Equity in Pedestrian and Bicycle Planning

Improving the ability of traditionally underserved communities to travel safely and conveniently via walking or wheeling is essential to achieving a sustainable, equitable transportation system that can provide options in how people access jobs, schools, health care services, faith entities, social gatherings, and other destinations.

Search: Bike Parking: 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.

Pg 199-208: 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.

Pg 1-4 : Application of Pedestrian Crossing Treatments for Streets and Highways

TRB's NCHRP Synthesis 498: Application of Pedestrian Crossing Treatments for Streets and Highways compiles information on the state of existing practices regarding application of pedestrian crossing improvements, and does not produce new guidance. The report includes a survey of state departments of transportation (DOTs) and local transportation agencies, a synthesis of current recommended practice and policy guidance, and a literature review of safety evidence for more than 25 pedestrian crossing treatments.
