Sharrow Cycle Markings

Flow have led the development of the new ‘sharrow’ bicycle markings for Auckland Transport.  In a New Zealand first, these innovative road markings have been approved for a twelve month trial at five Auckland locations from December 2013. Flow will also be undertaking a monitoring programme at these five sites, investigating the effects of the sharrows on both driver and cyclist behaviour.
