Signalised Roundabout Design for Pedestrian and Cyclist Safety

 

A difficult problem was reviewed by ViaStrada at the request of a road controlling authority.  An urban arterial road with a 50 km/h speed limit intersected a 100 km/h rural arterial at a large (60 m diameter) roundabout with two circulating lanes of traffic.  A range of options was considered. 

This technical note discusses a suggested solution where the roundabout would be signalised so that pedestrians and cyclists are able to cross onto the central island and off again to provide a direct and safe crossing of the rural arterial road.  The paper also highlights the tensions within the five objectives of the NZ Transportation Strategy.

The technical note and and conference presentation are available on our website.
