Literature review, analysis of crash statistics in Auckland and a survey of cyclists confirmed the original focus of this research, which was to design a low-speed multi-lane roundabout for on-road cyclists. The design of a roundabout that reduces maximum car speeds to 30 kilometers per hour rather than the conventional 50 kilometers per hour requires a confined geometry. The outcome of this research project is the Cyclist Roundabout, or ôCö Roundabout, which requires a narrow roundabout entry that relies on larger vehicles to straddle both entry lanes. The ôCö Roundabout as shown in this report is a design that may not be suitable for every intersection situation. Rather it is hoped that the design concept demonstrated here, will be taken into consideration alongside other options for any new junction designs or improvements.
