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).

Defining a trail corridor in law, policy, and planning.
Don Meeker, president of Terrabilt, reflects on trails as a critical sanctuary during COVID-19, and provides guidance on signage to keep everyone on trails safe. Terrabilt will also provide the production artwork for their COVID-19 trail sign for free.
IMBA Trail Solutions visited the Moose River Plains Wild Forest for one week in October of 2013 to conduct field research, meet with stakeholders, and to begin the process of developing a conceptual design for mountain bike use in the area. All of the designs presented in this report are conceptual in nature and have not been completely field verified. Additional work will need to be done in the field to finalize the designs of reroutes and proposed trails described in this report.
Bike parks are not trails. They are managed similarly to city parks. They require a higher standard of care. They need to be professionally designed and constructed.
