A comprehensive how-to manual for traffic calming in the United States. Planners and engineers can look to this manual for guidance on the appropriate use, design, and signing and marking of traffic-calming measures. For local officials, developers, and community associations, it is an introduction to the goals and tactics of traffic calming. Based in part on the first traffic-calming manual taken through a formal rule-making process and adopted by a state department of transportation as a supplement to its roadway design manual, this book catalogs principles that have been modified by many local jurisdictions to match local priorities and preferences. Standardization is key to the success of traffic-calming initiatives, and this book explains the processes, tools, and design needed to create a standard traffic-calming program. It also shows how municipalities can build needed flexibility into such programs. Signage and markings are also key, and a chapter is devoted to these issues. This is the book states and municipalities need to create effective traffic-calming programs.
