W 106th Street Design Approach
1. Creating Dedicated Cycling Space
2. Improving Intersection Safety
3. Traffic Calming for All Street Users
Project Goal: A Safer and More Comfortable W 106th
Street Corridor for ALL Street Users

2. Improving Intersection SafetyTurning Conflicts at Intersections
are Problematic– 9 of 10 NYC cyclist fatalities– 8 of 10 NYC cyclist serious injuries
Existing Conditions• No Guidance at Intersections
Planned Conditions• Bicycle lanes increase driver’s
visibility and awareness of cyclists• Intersection markings highlight
potential conflict

3. Traffic Calming for All Street Users
Existing ConditionsExcess road space• Speeding• Reckless driving/unpredictable lane
changes
Planned ConditionsDesign matches capacity to need• Fewer opportunities to speed
– Lead vehicle sets pace• Buffer markings define moving lane,
calm traffic

Central Park Loop Drive Connection Potential for Safe High Quality Link
• Short Path (<500’)• Wide enough for shared bike &
ped use (~17’)
![Page 15: Welcome to NYC.gov - 106th Street Safety & Bicycle Project … · 2008. 4. 10. · NYC DOT Bicycle Program. Central Park Loop Drive: Connecting to major cycling destinations like](https://reader033.vdocument.in/reader033/viewer/2022051603/5fee285e89827e3bb533e14b/html5/thumbnails/15.jpg)
Central Park Loop Drive Connection Design Considerations & Options• Entry Points
– Pedestrian Ramps vs. Between
• Signs and Markings for Path Connection– Gateway markings– Separate lanes for pedestrians
and cyclists– Separate lanes for directions
• Stakeholder input on options

Next Steps
• Community Feedback– Double Parking Issues– Park Connections
• Project Refinement• Project Installation: July 2008
