Traffic Calming ePrimer

The Traffic Calming ePrimer is a free, online resource openly available for public use. The ePrimer presents a thorough review of current traffic calming practice and contains the information needed to understand this complex field. The ePrimer is presented in eight distinct modules developed to allow the reader to move between each to find the desired information, without a cover-to-cover reading. The ePrimer presents:

  • a definition of traffic calming, its purpose, and its relationship to other transportation initiatives (like complete streets and context sensitive solutions);
  • illustrations and photographs of 22 different types of traffic calming measures;
  • considerations for their appropriate application, including effects and design and installation specifics;
  • research on the effects of traffic calming measures on mobility and safety for passenger vehicles; emergency response, public transit, and waste collection vehicles; and pedestrians and bicyclists;
  • examples and case studies of both comprehensive traffic calming programs and neighborhood-specific traffic calming plans;
  • case studies that cover effective processes used to plan and define a local traffic calming program or project and assessments of the effects of individual and series of traffic calming measures.


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.
