Project Details:

As part of the proposed 1,166-room Marriott Marquis Hotel adjacent to the new Washington Convention Center, AMT provided many services to Marriott, Inc. including site and traffic engineering, stormwater management, surveying and subsurface utility engineering.  To meet the District of Columbia’s requirements to rezone Square 370 to accommodate the hotel and underground parking for 400 vehicles, we performed traffic engineering services per the latest DDOT standards, signal design, environmental studies (air quality analyses to meet the EISF requirements), amongst others.

AMT investigated the impacts of the new development on the existing road network.  The traffic engineering services provided included the modeling of the nearby road network using Synchro/SimTraffic, including all existing roadway geometry and signal timings/phasing to establish baseline levels of service to determine the mitigation efforts required for this proposed development.   AMT prepared detailed signal plans for the conversion of two one-way streets to two-way during future build conditions, detailed signing and pavement marking plans.

The project faced such challenges as a limited right-of-way along Massachusetts Avenue that required innovative ideas to mitigate traffic to and from the hotel (i.e. valet parking, self-parking, bus drop-off and pick-ups, and taxis were all assigned to a specific street surrounding the hotel); the tedious task of retiming the signals to operate from one-way streets to two-way streets due to the specific nature of the residential neighborhoods surrounding the site; and persuading the community to “buy in” to the concept of a new hotel that would not create more traffic and noise along their neighborhood streets.
