Cycle Ipswich - Filtered Permeability

Presentation giving at the Cycle Ipswich meeting on 2014-02-13 about Filtered Permeability and how it relates to Ipswich, in part to spur conversation.

Transcript

1. Filtered Permeability Cycle Ipswich Shaun McDonald
2. Dutch cycle infrastructure • Filtered permeability • Routes • Cycle tracks • Traffic signal phasing • How do these relate to Ipswich?
3. Have you heard of filtered permeability before?
4. Do you know what filtered permeability is?
5. Filtered permeability is… • Motor vehicle access to every property • Short motor vehicle journeys are longer • Minimal effect on longer journeys • Short walking and cycling journeys more direct and faster than by car • Roads blocked for car use, while allowing pedestrians and cyclists • Example in Ipswich: Rope Walk
6. Where in Ipswich? • Residential areas with little cycling infrastructure currently • Stoke, Maidenhall, Chantry, Belstead Hills, Stoke Park • Westbourne, Whitehouse, Castle Hill, Whitton • California • Racecourse, Gainsborough, Greenwich
7. Types of road - The Netherlands • Major road • Between towns and cities • Always alternate routes for cyclists • Local distributer • Linking major roads to access roads • Usually segregated infrastructure • Access road • Quiet residential/shopping streets to get to properties, shops etc. • Through traffic minimised • Often cyclists share with motor traffic (very low volume and slow moving)
8. How to design • Each area is a set of cells with only one access for motor vehicles and many access routes for cyclists and pedestrians • Through cycle routes as alternative to main road • Main roads still need fast cycle infrastructure
9. Trials reducing stacking lanes • Camden are currently running trials to see what happens when stacking lanes at traffic lights are removed • Stacking lane space can be used for segregated cycling facilities instead • Improved safety as no longer merging through junction • Tool for access to/exit from filtered permeability areas • Source: https://twitter.com/aseasyasriding/ status/430745291038277632
10. Trial closures • Needs local residents on board • Initially use temporary measures in the form of a trial • Plant pots, removable bollards, play streets (e.g. 1 afternoon per week) • Can be easily removed or changed if it doesn’t work • Easier to implement politically
11. Implementing in Ipswich? • Where?
