4. Concerns, and how to design for them
ITE Informational ReportFindings on the current state of practice for installing separated bikeways in North America
PURPOSE
1. Summarize existing research and design guidance
2. Identify locations & design attributes of facilities already constructed in U.S. & Canada
3. Demonstrate the need for additional research on safety, latent demand, and design guidelines

Initial Survey Results
• List of nine problems with separation focuses on two-way shared use paths
• Discusses three types of path-roadway intersections: Midblock, Adjacent, and Complex
• Provides limited design guidance
• Does not prohibit separated bikeways
Design Guidance
Geographic Location of Separated Bikeways
Total Coverage:• 45 states• 5 provinces
Highest Coverage(# cities):
• California – 37• Florida – 13• Washington – 13• Ontario – 10

Cyclist Comfort onBusy Roadways
State of Cycling Report, SFTop two barriers to cycling:- Not enough bike lanes- Not comfortable riding with
cars

5. Concerns’ and how to design for them
Unexpected Movements
Bi-directional paths can create unexpected movements at intersections and driveways
Consider using single direction paths where there are many driveways and intersections
Turn Conflicts/Intersections
- Bring cyclists down to roadway level- Improve sightlines- Signalize- Slow turning drivers- Add high visibility markings
Left Turns
Maintenance:Sweeping and Snow
- Make path wide enough for street sweeper/plows- Buy smaller street sweepers/plows
Conflicts with Pedestrians
Ped demand very high, need for better lane placement and separation
Appropriate widths, good separation
Potential for Blockages andReduced Room for Passing
Rolled curbs aid passing/leaving path
Minimum 6.5’ (~2.0m) width to allow for side by side riding and passing
Additional Tool for Practitioners
Ultimate Goal?Positive Feedback Cycle
MORE CYCLISTS
More demand(for bicycle accommodation)
More accommodation
More awareness of cyclists
More safety
