Identifying Traffic Improvements to Offset Additional Traffic Generated by Development

Tysons Corner Center, located just outside the Washington, D.C. beltway in Fairfax County, VA, is ranked as one of the leading regional shopping centers on the east coast. Retail developer Macerich proposes to rezone the approximately 80-acre tract of land currently occupied by the regional mall to a Planned Development Commercial district.

In support of the Fairfax County Comprehensive Plan, the proposed redevelopment of Tysons Corner Center seeks to create an urban center. With a live, work, and play environment, it will emphasize public transportation through proximity to the proposed Tysons Central 123 Metro Station, and corresponding Travel Demand Management (TDM) program. 

W+A was retained to conduct a traffic impact study and assess the impacts of the proposed rezoning on the surrounding road network. The objectives of the study were: 

  • analyze existing transportation conditions
  • analyze future transportation conditions during the opening year of each development phase 
  • identify site-transportation impacts
  • identify improvements to mitigate site transportation impacts

We identified many transportation improvements to offset the impact of the additional traffic generated by the proposed redevelopment. Improvements include construction of additional lanes, adjustment of signal timings and phasings, installation of new traffic signals, widening of roadways, and restriping of intersections.
