CSS and Traffic Calming

"Traffic calming is the combination of mainly physical measures that reduce the negative effects of motor vehicle use, alter driver behavior and improve conditions for non-motorized street users." -Institute for Transportation Engineers, Traffic Calming: State of the Practice

Article Icon Article / Paper / Report Traffic Calming
Developed in Europe, traffic calming (a direct translation of the German "vekehrsberuhigung") is a system of design and management strategies that aim to balance traffic on streets with other uses. It is founded on the idea that streets should help create and preserve a sense of place, that their purpose is for people to walk, stroll, look, gaze, meet, play, shop and even work alongside cars - but not dominated by them. The tools of traffic calming take a different approach from treating the street only as a conduit for vehicles passing through at the greatest possible speed. They include techniques designed to lessen the impact of motor vehicle traffic by slowing it down, or literally "calming" it. This helps build human-scale places and an environment friendly to people on foot.

Policy Icon Policy Document Traffic Calming Design Manual - Delaware DOT
The Manual consists of roadway design standards that are intended to encourage closer adherence to posted speeds, discourage cut-through traffic, enhance vehicular and pedestrian safety and community aesthetics. The Department is doing this to directly support the provisions of the Statewide Long Range Transportation Plan, and county and local transportation and comprehensive land use plans.

Traffic Calming (also called Traffic Management) refers to various design features and strategies intended to reduce vehicle traffic speeds and volumes on a particular roadway. Table 1 describes some of these strategies. Traffic Calming projects can range from minor modifications of an individual street to comprehensive redesign of a road network. Home Zones refers to an area with extensive Traffic Calming. Traffic Calming is becoming increasingly accepted by transportation professional organizations and urban planners.

"The catalogue contains a brief description on the development of the traffic calming concept, the planning process, a short account of what can be achieved by reducing car traffic volume and lowering car speed, introduction of the concept of traffic management by design, the elements of urban space and speed levels - streets and roads, squares, points - from both large and mall towns, cheap and expensive solutions and both wholly and partly implemented schemes. Each example includes a description in text and pictures of the conversion and the results achieved."
