Research and development project

1. An International comparison of guidelines and recommendations for cycle infrastructureLouise Gustafsson

2. Research and development project • 3-year project (2010-2012) • Funded by the Swedish Transport Administration • The goal is to update and validate the current national guidelines for cycle infrastructure

3. Accessibility and traffic safety study of the bicycle infrastructure in Stockholm 2009

8. Special conditions during winter • Maintenance vehicles need access

9. Results of the study • Commuter cyclist • Mapping problems • Need for improvements Problems in many cases due • to lack of appropriate design guidelines • existing design guidelines not good enough

10. Design guidelines in Sweden • VGU (The Design of Roads and Streets) • Municipalities – several local design manuals • Part 1 – study of national and local guidelines • Part 2 – international comparison • Part 3 – field study to validate existing guidelines

11. International comparison • Denmark: Byernes trafikarealer: forudsaetninger for den geometriske udformning Idékatalog for cykeltrafik • Netherlands: Design Manual for Bicycle Traffic • Norway: Sykkelhåndboka Veg- og gateutformning • Germany: Richtlinien für die Anlage von Stadtstrassen • England: London Cycling Design Standards Cycle Superhighways Design Guideance Cycle Infrastructure Design Manual for Streets Design Manual for Roads and Bridges • USA: Guide for the development of Bicycle Facilities NYC Street Design Manual Bike Lane Design Guide Maryland Bicycle and Pedestrian Design Guidelines Highway Design Manual

12. Results Guidelines or required measures? • ”lowest acceptable” • Sweden: the road designer decides • Norway: clear differences between accepted and preferred • In several studied guidelines = not specified

14. gradient

15. Sight distance • AASHTO – national guidelines in USA • Based on gradient, e.g. • 0 % gradient + Speed 20 km/h = 20 m sight distance required • Sykkelhåndboka – national guidelines in Norway • Downhill slope = Special guidelines • CROW - Netherland • Based on speed and slope • Sight distance while moving, when stopping and when approaching another vehicle/cyclist

16. Cycle paths

17. Measures and values • Determine measures and values to adopt in Sweden • Need to consider cycle culture and existing norms • Guidelines – how to obtain enforcement?

18. Conclusion • Need for improved guidelines for sight distance and alignment • Capacity and flow of cyclist – dimensions • Netherland good example • Requirement or recommendation? • Need to specify level of demand • Sweden – only country without specific handbook for cyclist!

19. Summary • A research project 2010-2012 • Updating and validating existing guidelines • Proposal will include updated guidelines • Best practice and influences from other countries will be used
