On streets where people live and/or play and shop, there is a tension between preserving a safe pedestrian feel and moving cars quickly along. Studies of the relationships between road design, driver behavior, pedestrian behavior, roadside structures, traffic control, operating speed and safety show that changes in the shape or size or design of the road and changes in traffic control techniques can make drivers slow down. Benefits include improved pedestrian and driver safety, increased property values and increased livability of the surrounding area.

Traffic calming is the implementation of targeted changes to a street. The Institute of Transportation Engineers offers a searchable database of reports, articles and other documents related to traffic calming for those advocating and implementing these techniques. Electronic copies of over 100 documents are available in PDF format. Under "Library" is a collection of articles on traffic calming techniques including:

• cameras, radar speed traps
• bulbouts, chockers, curb extensions
• medians, pedestrian refuge islands
• roundabouts, traffic circles
• on-street parking
• raised crosswalks, rumble strips
• roadway marking, narrowing, texture
• speed bumps, humps

Under "Location" are a couple dozen pamphlets from (mostly) cities implementing traffic calming. Approximately 200 slides are available for free downloading in PowerPoint format under "Seminar Materials" for showing others pictures of traffic calming techniques.
