Traffic Calming

The Purpose of Traffic Calming

The FHWA and ITE define 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 features that use self-enforcing physical or psycho-perception means to produce desired effects such as:

  • Horizontal features
  • Lane narrowing

  • Vertical features
