I-95/I-395 Transit/TDM Study

About the Project
In conjunction with the I-95/I-395 HOV/Bus/HOT Lanes Project, a recommended plan has been developed to enhance transit and travel demand management services (TDM) in the corridor. TDM involves various services/strategies designed to reduce demand on roadways, including carpooling, vanpooling, and telecommuting.
DRPT managed the study and was guided by a Technical Advisory Committee consisting of local, state, regional, and federal jurisdictional/agency staff.

The Goals
The study addressed two goals:                
1) Maintain transit and High Occupancy Vehicle (HOV) ridership                             
2) Make use of the HOT lane features to attract new transit and HOV riders

Recommended Transit/TDM Improvements Included:

  • TDM initiatives to increase carpooling, vanpooling and slugging
  • Modifications to existing routes to serve new markets
  • New bus services        
  • Fixed guideway/rail
               - Bus Rapid Transit (BRT)
               - Enhanced VRE/Amtrak

Other capital improvements such as:

  • Improvements to transit stations
  • New/improved Park and Ride lots
  • In-line transit stations at major activity centers

HOV/Bus/HOT Lanes Project
The Virginia Department of Transportation (VDOT) partnered with Fluor-Transurban in the development of high-occupancy toll (HOT) lane projects for Interstates 95/395 and the Capital Beltway/Interstate 495. The projects were designed to help alleviate congestion.

The I-95/395 project expands the existing HOV lanes on I-95/395 from two to three lanes and extends two new lanes south to Massaponax.

Two HOV/Bus/HOT lanes have been added in each direction between the Springfield Interchange and just north of the Dulles Toll Road as part of the Capital Beltway/I-495 project.

All of these lanes have become HOV/Bus/HOT lanes – meaning buses and carpools with three or more people can continue to use the lanes for free, while non-HOV motorists can choose to pay a toll and access the lanes as well.

The new I-95/395 lanes are reversible, meaning traffic operations personnel will use them to move traffic into the region during peak in-bound commute times, and out of the region during out-bound peak periods, like traditional HOV lanes. The Capital Beltway HOV/Bus/HOT lanes are not reversible.
