Residential Traffic Management

The Department of Transportation and Capital Infrastructure (DTCI) coordinates with the Virginia Department of Transportation (VDOT) to address resident concerns regarding vehicular speed and safety on publicly-maintained roadways through the Traffic Calming Program and Cut-Through Traffic Program.

For each program, DTCI applies a step-by-step process as outlined in the Residential Traffic Management Guide, which complies with VDOT guidance and requirements. Each process includes problem recognition, identification of potential improvements, and inclusive participation with residents and partner agencies.

What is the Residential Traffic Calming Program?

The purpose of the Residential Traffic Calming Program is to lower vehicle speed on local roadways without restricting access. DTCI manages an eight-phase process to address traffic calming, which considers residents’ concerns regarding speeding, safety and overall quality of life on publicly-maintained residential streets.

If you or your neighbors see a need for traffic calming, please contact DTCI

What is the process?

The eight-phase process to address traffic calming includes the following: 

  • Step 1: Initial Contact and Review
  • Step 2: Traffic Calming Study Request
  • Step 3: Engineering Study
  • Step 4: Conceptual Plan and Development
  • Step 5: Community Support
  • Step 6: Final Plan Development
  • Step 7: Board of Supervisors Endorsement
  • Step 8: Implementation

A brief summary of each phase is provided for residents in the Residential Traffic Calming Program brochure (PDF).

How long does the process take?

Each residential street or community is unique and will present its own set of circumstances that affect the overall time frame, such as the complexity of the safety problem, size of the impacted area and level of community participation. From start to finish, the process can take six to 24 months, or longer. The Residential Traffic Management Guide provides a variable timeline for each phase of the process.

What measures are part of a traffic calming plan?

A range of engineering options can be part of a traffic calming plan, depending on the traffic volume. These include, but are not limited to: 

  • Watch for Children Signs.
  • $200 Fine signs.
  • Pole-Mounted Speed Display signs.
  • Speed humps.
  • Raised crosswalks.

Note: Stop signs are not suitable for use as traffic calming devices, so are not considered as part of this program.
