Traffic Calming	Previous  Index  Next
	There are numerous traffic calming features being designed, used, and studied throughout the country and internationally. The addition of any one or more of these features to a pedestrian facility will make the facility more comfortable. Combine several treatments such as speed tables at crosswalks and channelization to slow traffic. Corner Radii Reduce the typical corner radii to slow down turning vehicles. Suggestions include a radius as small as 10 to 15 feet (3 to 4.5m) where residential streets intersect to 25 to 30 feet (7.5 to 9m) where arterial streets intersect. Traffic Circles Place traffic circles at intersections on local and collector streets to slow cut through traffic. If used, traffic circles should be designed keeping in mind persons with visual impairments. It is harder for these pedestrians to know when it’s safe to cross the street because they cannot determine from which direction sound is coming. Channelization Narrow the street at the intersection or mid-block location, in order to reduce the width of the roadway to encourage drivers to slow down. Woonerf Convert the entire “street” to a living yard, or an area where no segregation is made between motorized and non-motorized traffic, so that pedestrians have full use of the entire area. Commonly woonerfs are narrow streets without curbs and sidewalks, and vehicle speed is reduced by placing trees, planters, parking and similar improvements within the roadway.
