Shared paths are paved, off-road facilities designed for travel by a variety of nonmotorized users, including bicyclists, pedestrians, skaters, joggers, and others. Shared-path planners and designers face a serious challenge in determining how wide paths should be and whether the various modes of travel should be separated from each other.
This document describes the development of a new method to analyze the quality of service provided by shared paths of various widths and the accommodation of various travel-mode splits. The researchers assembled the new method using new theoretical traffic-flow concepts, a large set of operational data from 15 paths in 10 cities across the United States, and the perceptions of more than 100 path users. Given a count or estimate of the overall path user volume in the design-hour, the new method described here can provide the level of service for path widths from 2.44 to 6.1 meters (8 to 20 feet).
The information in this document should be of interest to planners, engineers, parks and recreation professionals, and to others involved in the planning, design, operation, and/or maintenance of shared paths. In addition, this document will be of interest to researchers investigating how to analyze multiple modes of travelers in a finite space with minimal traffic control. This document describes a spreadsheet calculation tool called SUPLOS that was also developed as part of the same effort, and this tool is being circulated by the Federal Highway Administration (FHWA).

The Fort River Birding and Nature Trail is a universally accessible trail. It was presented with the 2014 Paul Winske Access Award by the Stavros Center for Independent Living.
For trails to be considered “sustainable” they must meet these recreational needs while providing adequate protection to the environment while minimizing trail maintenance.
This webinar describes the three most common forms of trail impact, identifies the most influential factors to develop and maintain sustainable trail networks, and discusses methods for rating trail sustainability.
The purpose of the Highway-Rail Crossing Handbook, 3rd Edition is an information resource developed to provide a unified reference document on prevalent and best practices as well as adopted standards relative to highway-rail grade crossings.
