Effects of Traffic Calming Measures on Pedestrians and Motorists
Course Highlights

This online engineering PDH course summarizes past research on speed humps, bulbouts, and roadway narrowing as well as findings from a new evaluation of bulbouts, raised crosswalks and intersections, refuge islands, and speed humps in eight communities.


Continued growth and decentralization throughout the United States have increased the number of cars on streets and highways. High traffic volumes and speeds, especially on residential streets, reduce the quality of life for residents because of concerns about safety, noise, and pollution. As a result, many neighborhood residents and local officials have expressed interest in undertaking traffic calming as a means of decreasing the cars' dominance.


Traffic calming encompasses a series of physical treatments that are meant to lower vehicle speeds and volumes by creating the visual impression that certain streets are not intended for high-speed or cut-through traffic. Thus, traffic calming can improve safety for pedestrians and reduce noise and pollution levels. Examples of these measures include bulbouts, speed humps, chicanes, and traffic circles.


This 2 PDH online course is applicable to transportation planners, traffic engineers, agency personnel as well as design and construction personnel involved with the development, review, approval, implementation, and assessment of traffic calming measures.
