Why here? Why now?• 2014: Fairfax County funds $1 million for bicycle
improvements around the Vienna Metro station as part of $1.4 billion Transportation Priorities Plan
• 2015: VDOT announces “Transform 66” plan which aims to add capacity to I-66 corridor
• 2015: Fairfax County DOT works with community and VDOT to include parallel trail in “Transform 66” project

Study Approach• Gather public input on existing conditions and safety
concerns for bicyclists in area• Analyze safety and operational conditions for
bicyclists• Identify candidate bicycle treatments for study
corridors• Develop typical cross-sections for candidate
treatments

Study Approach• 1st Public Meeting: March 2nd
– Focused on existing conditions, gather input from community on routes, trouble spots, desired bicycle infrastructure
• Pop up outreach: April 5th
– Two teams at Vienna Metro to intercept commuters and get feedback on bicycling in the area. Over 60 responses

Safety Analysis• Bicycle Level of Service and Bicycle Intersection Safety
Index– Bicycle Level of Service (BLOS) analyzes the level of
service (graded from highest "A" to lowest "F") on roadway segments;
• Variables Include: *Average effective width of the outside through lane *Motorized vehicle volumes *Motorized vehicle speeds *Heavy truck volumes *Pavement condition

Safety Analysis• Bicycle Level of Service and Bicycle Intersection
Safety Index– The Bicycle Intersection Safety Index (Bike ISI) is a
model that produces a safety index score, with higher scores indicating a greater priority for an in-depth safety assessment.
• The index is determined by calculating a separate value for bicycle crash potential for each turning movement at an intersection. The index is based on existing conditions and is a function of traffic speed, traffic volume, roadway width, traffic control, and other intersection conditions.

Candidate Treatments• Bicycle Level of Service and Bicycle Intersection
Safety Index - Results– Bicycle Level of Service:
• Almost all segments rated E (A-F scale)• Intersections rated D/E for bicyclists• Only looks at on road portion: No existing on road
infrastructure on any of these streets
– Bicycle Intersection Safety Index• Evaluated 201 turning movements at 19 intersections• Nearly all rated as low to moderate risk
