SafetyNET - Breathing Life into Road Safety Analysis
Track: Transportation
Authors: Kurt Janssen

SafetyNET is an innovative online interactive road safety tool developed for the New Zealand Transport Agency (NZTA). SafetyNET allows the NZTA to readily identify parts of the State Highway network where road safety performance is good or poor compared to national averages, where it out of character with the expected safety performance, and where it has engineering and operational features suggesting it may be a high risk site in the future. By displaying SafetyNET spatially, users can effortlessly identify high risk State Highway segments that warrant attention and target their investigations and investments accordingly.

This paper will be of interest to everyone interested in targeted identification, prioritization and funding of road safety improvements. Technically large quantum's of spatial data were manipulated and complex modelling of all New Zealand Highways at a 100m level ensued with many statistical indicators produced presented via an online flex viewer for consumption by the NZTA.
