A 3-year project funded by the Swedish Transport Administration to update national guidelines for cycle infrastructure. Findings from a study in Stockholm highlighting the need for design improvements and a comparison with guidelines from Denmark, Netherlands, Norway, Germany, England, and USA. The project aims to enhance safety, accessibility, and traffic flow for cyclists. Details include sight distance requirements, cycle path design measures, and the importance of aligning guidelines with local cycle culture. The study emphasizes the necessity for improved guidelines to meet the growing demands of cyclists.

An International comparison of guidelines and recommendations for cycle infrastructureLouise Gustafsson
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
Accessibility and traffic safety study of the bicycle infrastructure in Stockholm 2009
Special conditions during winter • Maintenance vehicles need access
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
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
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
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
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
Measures and values • Determine measures and values to adopt in Sweden • Need to consider cycle culture and existing norms • Guidelines – how to obtain enforcement?
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!
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
