Capacity Analysis of Pedestrian and Bicycle Facilities

Recommended Procedures for the "Bicycles" Chapter of the Highway Capacity Manual

1. INTRODUCTION

The following are the procedures recommended by the research team for future versions of Chapter 14, "Bicycles," of the Highway Capacity Manual(TRB, 1994). These procedures are recommended to determine the Level of Service (LOS) for bicycle facilities based on previous domestic and international bicycle operations research conducted to date as presented in the Bicycle Literature Review Section of the Research Reportfor this project (Rouphail et al., 1997). This document only addresses procedures for streets, roads, and intersections with designated bicycle facilities. Those without designated bicycle facilities will not be addressed here because they normally do not attract enough bicycle users to warrant operational analyses from the bicycle perspective. For an analysis of the characteristics of bicycle facilities that attract/deter cyclists, the reader is referred to a recent study by Harkey et al. (1998).
