Traffic Impact Study Yields Transportation Demand Management Recommendations

Twinbrook Commons is planned as a mixed-use, transit oriented village center, where residents can live, work, and play without using a car. Twinbrook Commons encompasses the east and west sides of the Twinbrook Metro station in the City of Rockville and Montgomery County. The site currently is occupied by 1,141 Metro park-and-ride spaces. 

The property is planned to be re-developed by The JBG Companies to have approximately 1,177 residential units; 200,000 S.F. of retail space; and 615,500 S.F. of general office space. The Metro parking spaces would be replaced in kind within the project. 

Twinbrook Commons is designated as Stage 2 Gold Certified under the LEED-ND Pilot Program. It is the first project in the Washington, D.C. metropolitan area to receive this distinction. 

W+A has conducted traffic impact studies of Twinbrook Commons east and west in compliance with the separate requirements of the City of Rockville and Montgomery County. To achieve their traffic impact reduction goals, our study recommended an aggressive Transportation Demand Management (TDM) program that centered on the project’s Metro location. The program included: 

  • Education and information 
  • Parking management 
  • On-site construction 
  • Commuter assistance programs
