The Federal Highway Administration published an idea book for mapping bicycle networks. The resource highlights ways that different communities have mapped their existing and proposed bicycle networks. It shows examples of maps at different scales, while also demonstrating a range of mapping strategies, techniques, and approaches. Facility types represented on the respective maps and legends are each different because they represent a community's unique context and needs.  The idea book is intended to serve as a resource to communities working to identify, plan, and improve their bicycle networks.
