Identifying optimal sites for static speed cameras in New Zealand – a geospatial approach
EXTENDED ABSTRACT: In an effort to reduce speed-related crashes, the New Zealand Police is expanding its network of static speed cameras. To help identify optimum sites for speed camera placement, Abley Transportation Consultants undertook an independent, evidence-based assessment using geographic information systems.
Using historic crash data, corridors with relatively high numbers of speed-related or high severity crashes were identified and ranked. Potential social cost reductions were then used to identify optimal camera locations on high risk corridors. The results of the analysis were presented in a web viewer to enable the Police to undertake further desktop scoping of potential camera sites.
