Multi-lane roundabouts are viewed by cyclists as a hazardous element of the road network to be avoided if possible. International literature review, cyclist crash statistics and cyclists themselves confirmed that the desired outcome is a roundabout design which reduces traffic speed and allows cyclists to use the road as equals with other vehicular users. The result of this 12-month research project is the Cyclist Roundabout, or C-Roundabout, which requires larger vehicles to straddle two traffic lanes. A roundabout in Auckland has demonstrated this is viable even in locations with heavy volumes of trucks. The main safety benefit to all users is that it slows down the maximum speeds of vehicles to around 30 kilometres per hour. It is also a compact design that offers an economic way to increase the number of traffic lanes through a roundabout and improve its capacity. A C-Roundabout now needs to be constructed and road trialled. (a) For the covering entry of this conference, please see ITRD abstract no. 0612AR242E.
