Previous Studies

• VDOT Study of Hunter Mill Road/Dulles Toll Road Interchange

• Hunter Mill Road Traffic Calming Study, NVRC

VDOT Alternatives Study

8

VDOT conducted a study of the Hunter Mill Road and Dulles Toll Road interchange in 2000, but no formal action was taken

Hunter Mill Road Traffic Calming Study

9

NVRC, Hunter Mill Road Traffic Calming Study, 2006

The study was sponsored by the Northern Virginia Regional Commission (NVRC) and completed in 2006. It provides both a traffic calming conceptual plan for Hunter Mill Road, as well as context sensitive roadway design techniques, as referenced in the Comprehensive Plan.

• LOS measures how well traffic moves along a roadway or delay at an intersection. LOS is generally defined in terms of speed and travel time, freedom to maneuver, safety, and traffic interruptions.

• Outside of Activity Centers the current County LOS standard is - LOS D for the peak hour(s)

Findings/Conclusions

• AM Peak Hour (Existing) – Dulles Toll Road EB Ramp is source of congestion northbound

• AM Peak Hour (Existing) – Crowell Road stop sign is source of congestion in both directions (northbound & southbound)

• PM Peak Hour (Existing) – Sunset Hills intersection is main source of congestion in both directions

32

Findings/Conclusions (Cont’d)

• By 2030 traffic conditions are anticipated to degrade

• At the EB DTR ramps: The ramp goes from LOS D to E during both periods and the intersection degrades from LOS B to C in the PM.

• At the WB DTR ramps: The ramp goes from D to E in the AM and E to F in the PM. In the PM the intersection degrades from a LOS D to E.

• Installation of signal at Crowell reduces delay in the long term

33

Question & Answers

• 15 Minutes maximum

• Please limit yourself to one question so others have an opportunity to ask questions

Charrette

• Discuss with group leader

• Be prepared to share ideas and proposals with the larger group

• Each group will report concepts

34

Summary and Next Steps• Review and document all presented ideas and

comments

• Develop future concepts for analysis

• Perform analysis of three alternatives

• Public meeting to present findings of analysis

• FCDOT will review ideas presented at previous meeting, and considerations given to each recommendation

• Community Feedback

• Public meeting to present preferred alternative
