  13. 13. County of Fairfax, Virginia Transit Oriented Development • Mixed-use walkable development around Metrorail stations • Supported by strong Transportation Demand Management (TDM) program • Enhanced pedestrian facilities • Increased transit ridership • More bike parking and access • Encourages carpooling • Teleworking Department of Transportation 13 Development 2050 Peak Hour – Future Trips 0 to ¼ Mile ¼ to ½ Mile Beyond ½ Mile Office 45% 40% 35% Residential 45% 40% 25% Technological Advancement 7.5% 7.5% 7.5% TDM Vehicle Trip Reduction Goals Reductions are from ITE Trip Generation Rates
  14. 14. County of Fairfax, Virginia Evaluating the Grid • Level of Service and Delay at Intersections • LOS E (55 – 80 seconds of delay) or better is the standard for the Reston Transit Station Areas agreed to by VDOT and FCDOT • Queue Length (number of cars waiting at a signal) • Walksheds – pedestrian accessibility • Enhanced connectivity for transit Department of Transportation 14
  15. 15. County of Fairfax, Virginia Achieving LOS E: Mitigation • Mitigation reduces vehicle congestion • Mitigation reduces delays experienced at intersections • Mitigation improves the reliability of travel times through an area (for both buses and vehicles) • Mitigation will be the way to achieve LOS E or better in the Transit Station Areas • Using mitigation measures that have the lowest impact Department of Transportation 15
  16. 16. County of Fairfax, Virginia Mitigation Department of Transportation 16
  17. 17. County of Fairfax, Virginia Mitigation Options • Mitigation Measures - Tiered Approach – 1st Tier: No right of way (ROW) impact – 2nd Tier: Limited right of way impact – 3rd Tier: Large scale mitigations if needed – Consultation with Advisory Group, Stakeholders, and citizens on all Tier 3 measures • Each grid link is initially assumed to be one lane in each direction – No turn lanes were initially assumed at new intersections Department of Transportation 17 Additional coordination will be needed with VDOT on the location of turn lanes at signalized intersections
  18. 18. County of Fairfax, Virginia 2050 Mitigation Measures • Tier 1 (no ROW impacts) – Modifications to lane configurations – Signal timing and phasing optimization – All-way stop vs. two-way stop evaluation – Additional traffic signals • Tier 2 (limited ROW impacts – Turn lanes: left and right turn lanes – Additional through lane(s) – Additional grid link(s) Department of Transportation 18
  19. 19. County of Fairfax, Virginia 2050 Intersection Control Department of Transportation 19
  20. 20. County of Fairfax, Virginia Problem Locations Department of Transportation 20 • Problem Locations were identified to help track the progress of mitigation measures • 120 seconds of delay was used to identify a problem location – LOS E is 80 seconds and 120 seconds represents 50% more delay than what is acceptable in the Reston TSAs. • Problem locations help staff understand where more effort would be needed to mitigate the transportation issues.
