I-66 Transit/TDM Study

About the Study
DRPT, in coordination with local jurisdictions and partnering agencies, conducted a transit/transportation demand management (TDM) study for the I-66 Corridor from Washington, D.C. to Haymarket, Virginia.

The study includes a review of potential short- and medium-term transit and TDM improvements for the I-66 Corridor that will increase mobility along the corridor.

DRPT managed the study in coordination with a Technical Advisory Committee comprised of local, state, regional and federal/jurisdictional/agency staff.

Goals and Objectives

  • Address local concerns of transit/TDM
    • Identify more transportation choices through transit and TDM enhancements that will increase mobility in the I-66 corridor
    • Recommend a plan for short- and medium-term transit and TDM service improvements in the I-66 Corridor

Study Recommendations

  • Priority Bus Stations and Ramps - direct access ramps in several locations
  • Runningway Improvements - signing and marking improvements
  • Recommended Transit Services - includes many elements of BRT that will improve the quality and dependability of transit service provided in the corridor
  • Park and Ride Lots - the addition of 3,000 spaces through capacity expansions at three existing lots and the construction of four new lots in the western end of the corridor
  • TDM Strategies - 15 TDM strategies recommended to reduce vehicle trips, provide a range of travel options, and raise awareness of transit services
