Traffic Calming: State of the Practice
ITE/FHWA, August 1999

This report contains a synthesis of traffic calming experiences to date in the United States and Canada.   It includes information on traffic calming in residential areas and in  areas where high speed rural highways transition into rural communities.  The report draws from detailed information collected on traffic calming programs in twenty featured communities, another 30 communities surveyed less extensively, and a parallel Canadian effort by the Canadian ITE (CITE) and the Transportation Association of Canada (TAC).  The intended audience is transportation professionals.

State of the Art: Residential Traffic Management
FHWA, 1980

The research program "Improving The Residential Street Environment" deals with control and restraint or management of traffic on local residential streets. This State of the Art report covers current practices in this field through 1978. The report assesses the performance of various control devices to affect traffic on existing residential streets (as opposed to initial design features of new Subdivisions). Included are diagonal diverters, half-diverters, cul-de-sacs, median barriers, speed bumps and undulations, stop signs, rumble strips and many other measures. The report also details techniques for developing neighborhood traffic control plans including community involvement and technical evaluation elements.

Canadian Guide to Neighbourhood Traffic Calming
TAC/CITE, December 1998

Traffic calming is receiving considerable attention in Canadian municipalities, but there is considerable variation in how traffic calming is defined, and how measures are applied in different communities. In conjunction with the Canadian Institute of Transportation Engineers, TAC has developed a Canadian Guide to Neighbourhood Traffic Calming to provide guidance for practitioners with understanding traffic calming principles and applications, and to achieve an appropriate level of standardization while minimizing liability and maximizing safety.

The Guide focuses on traffic calming measures for local and collector streets within established urban residential areas. Primarily oriented towards retrofit situations, the document recognizes the need for flexibility in the design of traffic calming measures to reflect local conditions. A detailed review of the applicability and effectiveness of a wide range of measures and a step-by-step process for developing a neighbourhood traffic calming plan with active participation from the community are included.

Front Matter  
Chapter 1

Introduction to Traffic Calming
Defines traffic calming, explains its role in transportation planning and neighbourhood planning, and identifies issues related to designing and implementing traffic calming plans.

Chapter 2

Community Involvement in the Traffic Calming Process
Outlines a recommended process for involving the community in the development of a traffic calming plan.

Chapter 3 Applicabilitiy and Effectiveness of Traffic Calming Measures
Describes a wide range of traffic calming measures, and includes tables identifying the benefits and applicability of each type of measure.  These tables are intended to assist users of this Guide in selecting measures which would be appropriate and effective in addressing specific neighbourhood traffic problems.
Chapter 4

Design Guidelines for Traffic Calming Measures
Provides design-related guidelines for traffic calming measures.
