Traffic Calming Assessment and Traffic Safety Investigation

Traffic Calming - black-and-white-striped speed hump

The District Department of Transportation (DDOT) is committed to improving the quality of life in our neighborhoods and addressing traffic-related safety issues throughout the city. In this effort, DDOT updated the traffic calming guidelines to incorporate a greater range of remedies for cut-through and speeding traffic. DDOT’s Transportation Audits use a variety of methods to improve safety, including traffic control devices, designs, traffic calming measures, education, and enforcement.

Traffic Calming and System Management refers to a balanced operation of the District’s street system, which fosters fluid, safe, and managed movement of traffic flows on the network. In particular, this means developing ways to tame traffic and protect neighborhood quality of life while also maintaining operational efficiency for all modes. Generally, traffic calming is required when you are concerned with speed and volume on your streets. This will require an assessment to be done by DDOT's traffic safety team. Any other request should be directed to 311.

DDOT Offers Several Services aimed at Traffic Calming and System Management:
