Abstract

On July 1st 1985, the New Zealand open road speed limits were raised, for most vehicles, by 20 km /h. This paper examines the effect these speed limits increases have had on vehicle speeds on a range of road types. It is concluded that, as a result of the speed limit increases, speeds of cars have increased on open roads of good geometric standards only, with this increase being in the vicinity of 2 km /h.
