Traffic Calming Measures


Traffic calming measures are a vital tool in ensuring our streets are safe and accessible for all. These measures range from signage to physical interventions, and among the most recognizable is the "speed bump." While speed bumps have been employed in various communities to manage vehicular speeds, it's essential to consider all aspects of this type of intervention before implementing them. This page delves into the nuances of speed bumps and possible alternatives to reduce speed. 

Considerations and Concerns:

  • Speed bumps do not always reduce vehicle speeds once the vehicle has crossed them.
  • They can pose a hazard to vehicles, emergency services, and cyclists.
  • Installing speed bumps might lead to increased traffic on neighboring streets.
  • They can raise noise levels by 10-20 decibels when vehicles pass over.
  • The State of California does not recognize speed bumps as an official traffic calming measure. Thus, there are no state regulations or requirements for their installation.

Level 1 Alternatives to Speed Bumps:

  • Targeted Sheriff Enforcement: Deputies can be dispatched to specific streets to curb speeding through traffic citations.
  • Temporary Radar Trailer: This device can be parked roadside to detect and show vehicle speeds, thereby discouraging speeding.
  • Speed Limit Signs and Pavement Markings: They remind drivers of the legal speed limit.

Level 2 Alternatives to Speed Bumps:

  • In 2022, the California Department of Transportation issued a Memorandum on Traffic Calming Guidance which suggests measures like:
    • Crosswalk Enhancements
    • In-Street Pedestrian Crossing Signs (R1-6)
    • Radar Feedback Signs
  • Visual Roadway Narrowing: Achieved by striping that separates the travel lane from the parking lane. It gives drivers a confined feeling, prompting them to reduce speeds.
