The Canadian Guide to Traffic Calming (Second Edition) presents traffic calming as a method to reduce the speed and/or volume of non-local traffic infiltrating into neighbourhoods. It explains principles and suggests a process for introducing and implementing traffic calming, and describes the applicability, effectiveness, and design principle for a wide range of traffic calming devices. The devices are categorized in terms of vertical deflection, horizontal deflection, roadway narrowing, surface treatment, pavement markings, access restriction, gateways, enforcement, education, shared space, and emerging technologies and measures.

The original Canadian Guide to Neighbourhood Traffic Calming was published in 1998. This second edition reflects changes in road conditions, attitudes toward vulnerable road users, and available technologies, and valuable experience regarding the efficacy of options. Changes and additions include:

·         Recognizing education and enforcement as valid, and/or preferred alternatives to physical measures;

·         Describing measures applicable to arterial roads and rural roads;

·         Adding traffic calming devices, some well-accepted and others not fully-proven but used with success and considered ready to be further tested and evaluated; and

·         Referencing performance outcomes where new information has become available since the first edition.

The Guide is a complete tool; each chapter has a specific and integrated intent and no chapter should be used independently from the rest of the Guide. It was created through a partnership between the Transportation Association of Canada and the Canadian Institute of Transportation Engineers (CITE).
