CANADIAN CAPACITY GUIDE FOR SIGNALIZED INTERSECTIONS. SECOND EDITION

Abstract

This Second Edition of the Canadian Capacity Guide for Signalized Intersections is an updated, enhanced and significantly expanded version of this important traffic engineering document. Techniques included in this guide allow the user to analyze different situations and intersection configurations. The focus of the guide is on the movement of traffic flow units, such as cars, trucks, transit vehicles, cyclists, and pedestrians at signalized intersections. The main parameter is the time dimension that determines how efficiently the available roadway space is used by conflicting traffic streams. The allocation of time to the movement of vehicular and pedestrian traffic in lanes and crosswalks influences not only intersection capacity, but also a number of other measures that describe the quality of service provided for the drivers, passengers, pedestrians and cyclists. To this end, and to provide input to investigations of possible impacts, the guide provides both analytical and evaluation methods, and a set of up-to-date numerical parameters for Canadian conditions.
