Traffic Control Design

Work zone traffic control plans are developed in conjunction with plans for transportation improvement projects, new facilities or modifications to roadways, bridges, and traffic control devices. The aim of traffic control in work zones is twofold: to maintain a safe and continuous flow of vehicular and pedestrian traffic and to protect workers and equipment in the construction zone. Temporary traffic control devices are specified to alert drivers to changes in accustomed patterns and direct them through construction zones in a safe manner. AMD Engineering understands that effectively managing traffic in and around construction work zones is critical to the mobility of drivers, bicyclists, and pedestrians.

The AMD Engineering team has designed Maintenance of Traffic (MOT) and Transportation Management Plans (TMP) for jurisdictions throughout the DC Metro Area including MDOT SHA, VDOT, DDOT and many local agencies throughout the region. AMD Engineering has developed a standardized TMP template which accompanies every MOT plan and includes a project description, allowable hours for closure(s), public communications plan, sequence of construction, general notes, and a section for details that are unique to each project. AMD Engineering's principals and support services staff understand the region's varying mobility needs and the steps involved in civil construction which allows us to develop MOT and TMP plans that minimize impacts to the public.

AMD Engineering is well versed in the temporary traffic control guidance in Part 6 of the MUTCD along with local agencies' supplemental guidance including the Virginia Work Area Protection Manual and VDOT IIM-LD-241.5, which outlines typical work zone management strategies for different types of improvement projects (Types A through C); and DDOT's Work Zone Temporary Traffic Control Manual. The appropriate strategy for the duration of work, posted speed, and work zone condition is selected.

Our MOT experience spans some of the region's most complex work zones, from multi-phase MOT for Capitol Crossing, built over I-395 while interstate traffic was maintained underneath, to signal and MOT staging for the CBBT Parallel Thimble Shoal Tunnel, the TMP for the I-95 Express Lanes Southern Terminus Extension, and MOT alternatives during construction on the I-66 Outside the Beltway Express Lanes. AMD staff hold the VDOT Advanced Work Zone Traffic Control certification, and our principals review and seal MOT plans for jurisdictions throughout Northern Virginia and Maryland.
