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).

Exhibitions are complex presentations that convey concepts, showcase objects, and excite the senses. However, as museums recognize the diversity within their audiences, they realize that exhibitions must do more: exhibitions must teach to different learning styles, respond to issues of cultural and gender equity, and offer multiple levels of information. The resulting changes in exhibitions have made these presentations more understandable, enjoyable, and connected to visitors’ lives.
Responsible equestrians should actively protect trees and other park structures when out on the trail. Equine expert Lora Goerlich gives her take on this topic.
In the context of mountain bike trails, excellence is realized when a trail design merges the desired outcomes and difficulty that a rider seeks with the setting in which the outcomes are realized.
The purpose of this plan is to assess progress to-date and develop a strategy to connect local and regional systems into a statewide trail network reaching to all areas of the Commonwealth.
