Problems with Sidewalk Bikeways
• Treat bicyclists as pedestrians – however, bicyclists are less maneuverable than pedestrians and therefore less able to deal with the conflicts experienced by pedestrians
![Page 9: Sidewalk Bikeways: A Safety Problem, Not a Safety Solution](https://reader035.fdocuments.us/reader035/viewer/2022070413/56814c7a550346895db99702/html5/thumbnails/9.jpg)
Problems with Sidewalk Bikeways
• Require users to scan both ahead and behind at intersections
• Motorists more likely to block sidepaths than bike lanes or wide curb lanes
![Page 10: Sidewalk Bikeways: A Safety Problem, Not a Safety Solution](https://reader035.fdocuments.us/reader035/viewer/2022070413/56814c7a550346895db99702/html5/thumbnails/10.jpg)
Problems with Sidewalk Bikeways
• Motorists must scan wider areas than they normally would
• Cyclists who choose to stay on the roadway will be harassed
![Page 11: Sidewalk Bikeways: A Safety Problem, Not a Safety Solution](https://reader035.fdocuments.us/reader035/viewer/2022070413/56814c7a550346895db99702/html5/thumbnails/11.jpg)
The Skills Myth: “On-Road Cycling Requires More Skill than Sidepath
Cycling”• The scanning skills
necessary for cycling on a sidepath are MORE COMPLEX than for cycling on the roadway
![Page 12: Sidewalk Bikeways: A Safety Problem, Not a Safety Solution](https://reader035.fdocuments.us/reader035/viewer/2022070413/56814c7a550346895db99702/html5/thumbnails/12.jpg)
The Skills Myth: “On-Road Cycling Requires More Skill than Sidepath
Cycling”• The motorist’s side of the
equation – sidepaths require motorists to scan for cyclists MORE THOROUGHLY than on-road facilities
• This often occurs at the same time and place where cyclists are required to conduct more complex scans
![Page 13: Sidewalk Bikeways: A Safety Problem, Not a Safety Solution](https://reader035.fdocuments.us/reader035/viewer/2022070413/56814c7a550346895db99702/html5/thumbnails/13.jpg)
The Skills Myth: “On-Road Cycling Requires More Skill than Sidepath
Cycling”• For some conflicts, bicyclists
on sidepaths must have BETTER braking or steering skills than if they were on the roadway

Unidirectional Paths Are Not Unidirectional
• On multi-lane highways, cyclists with a destination a short distance away on the same side of the street will often avoid crossing the street by driving facing traffic
![Page 24: Sidewalk Bikeways: A Safety Problem, Not a Safety Solution](https://reader035.fdocuments.us/reader035/viewer/2022070413/56814c7a550346895db99702/html5/thumbnails/24.jpg)
Unidirectional Paths Are Not Unidirectional
• A standard five-foot unidirectional path will not safely accommodate two cyclists approaching head-on
• Who will enforce it?
