Part I

Background to the Guidelines


Who do we have here today l.jpg

Who do we have here today?

Cycle Friendly Infrastructure (CFI)


Slide19 l.jpg

Cycle Friendly Infrastructure (CFI)

  • First published in 1996


Slide20 l.jpg

Cycle Friendly Infrastructure (CFI)

  • First published in 1996

  • “Time for an update!”


Slide21 l.jpg

  • My role was:

    • as a consultant

    • reviewing the guidelines

    • submitting comments

    • representing the

      devolved state of

      Scotland.

Part II

Changes to the Guidelines


Changes to the guidelines l.jpg

Changes to the Guidelines

  • Cyclist’s Dynamic Envelope

  • Maintenance

  • Advanced Stop Lines (ASL’s)

  • Side Road Crossings

  • Access Control

  • Invisible Infrastructure


Slide24 l.jpg

How much space does a bicyclist need on the road?

Maintenance l.jpg

Maintenance

  • Create a maintenance hotline

  • Inspect by bicycle

  • Budget early

    for maintenance


Maintenance30 l.jpg

Maintenance

This handy maintenance checklist will be included


Advanced stop lines asl s l.jpg

Advanced Stop Lines (ASL’s)

  • No adverse impacton traffic capacity

  • Results in 25-35% accidentreduction

    for cyclists

  • Inexpensive

Slide35 l.jpg

Are cyclists safer on

off-road cycle paths?


The short answer l.jpg

The short answer:


Slide37 l.jpg

No.

(the long answer: it depends)


In the hierarchy of solutions l.jpg

in the Hierarchy of Solutions …


Providing cycle paths are your last choice l.jpg

… providing cycle paths are your last choice

Hierarchy of Solutions

(1) Traffic Reduction

(2) Traffic Calming

(3) Intersection Treatment

(4) Roadway Redistribution

(5) Segregated Facilities

First Priority

Last Priority

When should you use access control l.jpg

When should you use access control?


Only if there is a proven need l.jpg

And last but not least l.jpg

… and last but not least:


Invisible infrastructure l.jpg

“Invisible Infrastructure”


Remember hierarchy of solutions l.jpg

Remember “Hierarchy of Solutions?”

(1) Traffic Reduction

(2) Traffic Calming

(3) Intersection Treatment

(4) Roadway Redistribution

(5) Segregated Facilities

First Priority

Last Priority


Invisible infrastructure refers to the idea that l.jpg

Invisible Infrastructurerefers to the idea that:

  • Traffic Reduction

  • Traffic Calming

  • …are more effective than “visible”

    cycle-specific improvements.
