Skip to content Ontario. MTO 's Research Library is the go-to place for technical information and research. It is one of Ontario's most significant collections of transportation information. Full text versions of MTO technical manuals, standards, policy and development reports, studies, and research papers are available.
Publications in PDF are attached to the catalogue record, look for the paperclip icon and click on it to view the document. Some larger publications have been attached in two or more sections to assist in downloading. Our goal is to ensure access in everything we do for our employees and the public we serve.
Publications are available in alternate formats upon request. Please contact MTO. Skip to main content. Search form Search. McElhanney Ltd. Geometric Design Guide for Canadian Roads. Chronology — A new edition of the Guide was released, with ten chapters and comprehensive updates. Chapter 1 - Design Philosophy offers an introduction to the goal of design, its evolving approach and the design domain concept utilized throughout the guide; and provides benefit cost analysis, value engineering and design exceptions guidance.
Chapter 2 - Design Controls, Classification and Consistency discusses how design controls such as human factors, speed, design vehicles and sight lines influence geometric design; demonstrates how to classify links in a road network to provide a hierarchical and readily understood road system that appropriately serves different purposes; and outlines the principles of providing consistency in cross section, operating speed and driver workload.
Chapter 3 - Alignment and Lane Configurations focuses on design procedures and domains associated with horizontal and vertical alignment, the coordination of these two design elements and related issues including cross slopes, lane widening, lane balance, lane continuity and specialized traffic lanes such as truck climbing lanes, passing lanes and truck escape ramps.
Chapter 4 - Cross Section Elements offers guidance on design procedures and domains related to cross sections and related elements including special purpose lanes, shoulders, medians, outer separations and boulevards, curb and gutter and drainage; and presents considerations for bridges and utility placement, snow storage and future widening, as well as typical cross sections. Chapter 5 - Bicycle Integrated Design identifies examples on how to integrate the design of bicycle facilities holistically into the design of roadways to provide a balanced solution for all modes and road users; and provides guidance on bicycle and in-line skater design needs, types of bicycle facilities, a framework for the selection of an appropriate type of facility, and specific design elements.
Chapter 6 - Pedestrian Integrated Design highlights examples on how to integrate the design of pedestrian facilities holistically into the design of roadways to provide a balanced solution for all modes and road users; provides guidance on pedestrian and wheelchair design needs, use of a framework approach to design which subdivides the roadside into frontage, pedestrian through and furnishing zones and specific design elements; and addresses integration with other design elements including adjacent roadway lane widths, roundabouts and bridges and other travel modes.
Chapter 7 - Roadside Design introduces road safety concepts and the use of quantitative analysis to evaluate roadside safety design options; outlines the fundamental concept of the clear zone and its application through provision of appropriate cross section and drainage elements to allow for driver recovery; outlines mitigation and protection techniques to reduce the severity of fixed-object collisions with roadside furniture including signs, luminaires and traffic barriers; and discusses roadside design in urban environments and for low volume roads.
Chapter 8 - Access presents access management guidelines for the full range of road classifications; provides guidance for each classification of roadway, balancing its role in addressing traffic mobility and access to adjacent lands; and outlines design guidance for access location and geometrics and the use auxiliary lanes, two-way left-turn lanes and service roads to accommodate access in a safe manner.
