(Washington, DC)--The District Department of Transportation (DDOT) today announced it will launch the latest phase of its multi-year traffic congestion mitigation strategy starting Friday, August 4, 2017, at 8 pm. The plan is designed to improve traffic flow, improve pedestrian safety, and reduce transit running times throughout the District.

DDOT will implement new traffic signal timing plans for 384 intersections in Northeast and Southeast Washington, DC. The implementation effort will continue through mid-August.

“Reducing traffic congestion improves the quality of life for District residents, enhances the business environment, and allows visitors to enjoy the full experience of all the District has to offer without wasting time stuck in traffic,” said Leif A. Dormsjo, DDOT Director. “We’re seeing the results of our congestion mitigation strategy in areas where the traffic signals have already been optimized, and we look forward to moving into this next phase.”

DDOT engineers are reprogramming the traffic signals using updated pedestrian, cyclist, transit, and vehicular traffic data along with new traffic models reflecting changes in lane configuration and signal timings that have taken place over the years. The new timing plans have been designed to accommodate the District’s varying travel demands by time-of-day, including the morning, midday and evening rush hours, as well as the diverse patterns experienced on weekdays, weekends and late at night.

The project also seeks to optimize pedestrian crossing times, reduce motorist travel times, reduce emissions and fuel consumption. The five-year citywide signal optimization initiative started in 2012 and is intended to improve the District’s entire traffic signal network of more than 1,650 signals by the end of 2017. The initiative was the first comprehensive re-timing of signals in the District and responded to changing development and usage patterns. DDOT will initiate the next five-year cycle of signal optimization in 2018.

The previous phase of work was completed in Spring 2016 and included nearly 400 intersections in the Northwest Washington, DC, area. The boundaries of the latest implementation area include the area of North/South Capitol Streets in the west, Eastern Avenue and the Anacostia River to the east, Kansas Avenue/Missouri Avenue in the north, and Southeast/Southwest Freeway (I-695) in the south.

DDOT will be monitoring, as well as making adjustments to, the traffic signal timing operations through mid-August. DDOT advises motorists to use caution in these areas as they become acquainted with the new signal timing patterns.

The mission of the District Department of Transportation (DDOT) is to enhance the quality of life for District residents and visitors by ensuring that people, goods, and information move efficiently and safely with minimal adverse impact on residents and the environment.
