The primary objective of this study is to develop an integrated multimodal simulation system for the I-270 corridor, which includes the I270 freeway and its parallel routes, the subway and rail lines from the city, German Town, all way to the I-495 Capital Beltway.  The proposed system shall serve as an effective tool for responsible transportation agencies to address the following vital issues:

  • The impact of HOT and other control strategies on the distribution of traffic patterns
    along the I270 freeway and among all available commuting transportation modes;
  • The cost-benefit of any proposed new supply-side congestion mitigation plan, such as additional travel lanes, light rail line, BRT, and their impacts on the distribution of daily travel demand among all transportation models;
  • The impact of any major land-use development on the spatial and temporal distribution
     of traffic congestion patterns; and
  • The optimal distribution of commuting trips between all available modes during major incidents where one or more modes suffer a substantial capacity reduction.
