The Bicycle Signals Resource Hub is an interactive webpage to assist transportation professionals in the planning, design, and operation of bicycle traffic signals.  This Resource Hub is intended to identify current design guidance and practices related to the use of bicycle signals and provide information on applications in communities throughout the United States, Canada, and internationally.

While red, yellow, and green bicycle symbols in traffic signal faces have been used for many years internationally, prior to 2013, applications in the United States were limited with only a relatively small number of cities experimenting with them. These cities recognized that bicycle signals could enhance safety and guidance for bicyclists traveling through intersections. Since 2013, bicycle signal use has grown significantly as more jurisdictions have come to understand the benefits bicycle signals can provide.

Purpose of Bicycle Signal Resource Hub

The overall goal of the Bicycle Signals Resource Hub is to serve as a reliable and informative resource for the planning, design, implementation, and operational guidance of bicycle signals including design practices that are contained in IA-16, as well as those presented in the National Association of City Transportation Officials (NACTO) Urban Bikeway Design Guide, The American Association of State Highway and Transportation Officials (AASHTO) Guide for the Development of Bicycle Facilities, FHWA Separate Bike Lane Planning & Design Guide, as well as various city, county, state, and even international design manuals. Design guidance from international sources is also presented. Finally, the Resource Hub presents information on research conducted and technical articles on bicycle signals.

The Bicycle Signals Resource Hub is broken into the following sections. Click on the sections below to learn more about different bicycle signal resources.
