Basic Principles

Operating any vehicle in traffic (whether on a roadway or a path) requires:

  • Skills
  • Knowledge
  • Judgment
basic principles3
Basic Principles

Knowledge

  • Rules of the Road
  • Defensive Driving Techniques

Judgment

  • Applying Knowledge and Skills to Existing Conditions
slide4
Skills for Cycling on Neighborhood Streets
  • Starting
  • Steering/Balance
  • Braking
  • Scanning Ahead
  • Judging Speed of Other Vehicles
  • Scanning Behind Without Swerving
  • Driving One-Handed to Signal
slide5
Skills for Collector & Arterial Streets
  • Starting
  • Steering/Balance
  • Braking
  • Scanning Ahead
  • Judging Speed of Other Vehicles
  • Scanning Behind Without Swerving
  • Driving One-Handed to Signal
slide6
Skills for Cycling on Sidepaths
  • Starting
  • Steering/Balance
  • Braking
  • Scanning Ahead
  • Judging Speed of Other Vehicles
  • Scanning Behind Without Swerving
  • Simultaneously scanning ahead and behind
  • Driving One-Handed to Signal
which is safer the street or the sidewalk
Which is Safer -- the Street or the Sidewalk?

Higher Number Indicates Higher Risk of Bicyclist Crash with a Motorist

problems with sidewalk bikeways
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
problems with sidewalk bikeways9
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
problems with sidewalk bikeways10
Problems with Sidewalk Bikeways
  • Motorists must scan wider areas than they normally would
  • Cyclists who choose to stay on the roadway will be harassed
the skills myth on road cycling requires more skill than sidepath cycling
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
the skills myth on road cycling requires more skill than sidepath cycling12
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
the skills myth on road cycling requires more skill than sidepath cycling13
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
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
unidirectional paths are not unidirectional24
Unidirectional Paths Are Not Unidirectional
  • A standard five-foot unidirectional path will not safely accommodate two cyclists approaching head-on
  • Who will enforce it?

A Choice:Greater Increase in Perceived Safety but with a Decrease in Real Safety(sidepath)or aLesser Increase in Perceived Safety with an Increase in Real Safety(bike lane or wide curb lane)
