Risk Maps - How the sections were defined

Traffic and crash data is used to produce maps illustrating the relative level of risk on sections of the road network.

KiwiRAP focuses on lengths of state highway that have speed limits of 80km/h or more and are typically outside the urban area between major town centres.

Overall, it analyses close to 11,000km of State Highways that have been broken up into about 170 'links' and calculates their risk levels at both a collective and personal level.

There have been three sets of KiwiRAP Risk Maps produced in 2008, 2012 and 2018. Each set of maps was based on five-years of crash data.

Risk Maps from 2018, 2012 and 2008 are available in the Downloads section.
