Federal Highway Administration and Institute of Traffic Engineers Definition of Traffic Calming
The primary purpose of traffic calming is to support the livability and vitality of residential and commercial areas through improvements in non-motorist safety, mobility, and comfort. These objectives are typically achieved by reducing vehicle speeds or volumes on a single street or a street network. Traffic calming measures consist of horizontal, vertical, lane narrowing, roadside, and other features that use self-enforcing physical or psycho-perception means to produce desired effects.
4th Street Improvements
The 4th Street Rehabilitation Project added the principles of the Complete Streets Policy by expanding the sidewalk to incorporate bike lanes and reducing the width of the motor vehicle lanes, thereby reducing the speed at which motor vehicles travel.
