There are several enhancements that can be introduced to improve safety for pedestrians and bicyclists. The safety treatments shown in the table below can be employed to improve pedestrian and bicycle safety at intersections in particular. The table also shows the associated crash modification factor (CMF) or crash reduction, the safety issue addressed, and the typical cost of implementation.
The Roadside Design Guide presents a synthesis of current information and operating practices related to roadside safety and is written in dual units—metric and U.S. Customary.
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.
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.
This guide provides information on how to accommodate bicycle travel and operations in most riding environments. It is intended to present sound guidelines that result in facilities that meet the needs of bicyclists and other highway users. Sufficient flexibility is permitted to encourage designs that are sensitive to local context and incorporate the needs of bicyclists, pedestrians, and motorists. However, in some sections of this guide, suggested minimum dimensions are provided.
Approximately one out of six highway fatalities in the United States is a bicyclist or pedestrian each year. Estimates for 1995 indicate that 61,000 bicyclists were injured and 830 were killed in traffic crashes. These crashes can be classified or "typed" by their precipitating actions, predisposing factors, and characteristic populations and/or location that can be targeted for intervention.

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.
The Bicycle Safety Guide and Countermeasure Selection System is intended to provide practitioners with the latest information available for improving the safety and mobility of those who bike. The online tools provide the user with a list of possible engineering, education, or enforcement treatments to improve bicycle safety and/or mobility based on user input about a specific location.
Transportation agencies face growing demand for an integrated transportation network that safely and efficiently move people. Motorists, freight, transit passengers, bicyclists, and pedestrians, including individuals with disabilities, have unique needs, and infrastructure is being adapted to the multimodal nature of travel. The project development process for multimodal projects - those intended to serve bicyclists and pedestrians - can experience delays and challenges as projects move from one phase to the next.
