A tremendous amount of work at the District Department of Transportation (DDOT) is done behind the scenes, long before crews break ground on construction projects. Our planning staff designs new projects and guides them from concept to engineering. Their studies also help identify necessary improvements and help shape the District’s transportation policies. See also the Livability Studies. At the same time, DDOT’s Research, Development, and Technology Transfer Program promotes innovative solutions to transportation problems and works with other department staff to integrate new technology into DDOT’s projects.
The District is a leader in transportation innovation and welcomes the opportunity to conduct research on its streets. Researchers and innovators seeking to pilot, test, or demonstrate new technologies and approaches should complete the initial application for gathering ideas. This application helps researchers and companies focus their proposals based on DDOT’s values and allows DDOT to prioritize and test ideas most relevant to the needs of the residents, businesses, and visitors of the District. Complete the application here.
DDOT funds and conducts a small number of applied research projects annually. Problem statements are accepted year-round; however, research project ideas are selected annually, beginning in June. To move forward, DDOT-funded projects must have a DDOT staff willing to champion the project. The Research Program will identify champions for submitted ideas. Please submit your ideas to [email protected] using this project statement template.

moveDC is the long-range transportation plan for the District of Columbia. Under Mayor Bowser’s leadership, the moveDC plan was updated in 2021 and establishes goals, policies, strategies, and metrics for the District Department of Transportation (DDOT) to invest in transportation facilities and programs that address the needs of Washingtonians across all eight wards. The plan identifies goals for the following seven topics: safety, equity, mobility, management and operations, project delivery, sustainability, and enjoyable spaces.
DDOT developed an original draft Traffic Study report in October 2021 to help inform NPS' decision about whether to reopen Upper Beach Drive. The modeling in that original report did not incorporate four major projects that could potentially impact traffic volumes in the study area:
- 16th Street bus lane project
- Georgia Ave bus lane project
- Connecticut Ave reversible lane/protected bike lane project
- Potential Rock Creek/Potomac Parkway reversible lane elimination (currently a study)
DDOT believes the revised report provides a more accurate and comprehensive understanding of the impacts of the Upper Beach Drive closure. The study includes three scenarios – Upper Beach Drive open, closed, and closed with mitigation to assess traffic volumes, delays, and queuing at intersections at AM and PM peak hours as well as environmental impacts. The study now shows that there would be a meaningful impact on traffic patterns in the area, particularly during certain hours of the day. The study recommends mitigations and roadway improvements, as well as consideration of only partial closure during certain seasons or times of the day to reduce the impact to surrounding neighborhoods.
The study identified the following impacts that would result from a full-time closure of Beach Drive:
- Additional travel time of approximately 7.5 minutes in the peak hour peak direction;
- Additional congestion cost of over $18 million dollars annually;
- Over 50% increase in emissions in the peak hour, peak direction;
- Six additional intersections operating at near capacity or over capacity (failing) condition in the AM peak and four in the PM peak;
- Additional traffic on the local and collector streets in the Barnaby Woods area of northwest DC;
- Inability to provide east-west connections for school access; and
- Other previously planned FHWA roadway projects in the nearby areas could require either one-way or two-way detours, which will further impact traffic operations on other roadways in the area.
