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.1

Traffic calming goals include:

  • increasing the quality of life;
  • incorporating the preferences and requirements of the people using the area (e.g., working, playing, residing) along the street(s), or at intersection(s);
  • creating safe and attractive streets;
  • helping to reduce the negative effects of motor vehicles on the environment (e.g., pollution, sprawl); and
  • promoting pedestrian, cycle and transit use.1

Traffic calming objectives include:

  • achieving slow speeds for motor vehicles,
  • reducing collision frequency and severity,
  • increasing the safety and the perception of safety for non-motorized users of the street(s),
  • reducing the need for police enforcement,
  • enhancing the street environment (e.g., street scaping),
  • encouraging water infiltration into the ground,
  • increasing access for all modes of transportation, and
  • reducing cut-through motor vehicle traffic.1
