Transcript

  1. Dutch cycle infrastructure • Filtered permeability • Routes • Cycle

    tracks • Traffic signal phasing • How do these relate to Ipswich?
  2. 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
  3. 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
  4. 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)
  5. 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
  6. 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
  7. 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
