Recent research
One of the objectives of these pages is to promulgate and publicise research to encourage wider adoption of research recommendations and the application of findings. To this end this page provides a summary of recent NZTA research reports and other presentations. For a list of currently active research projects and approved projects not yet commissioned, click here.
The NZTA-NZIHT 12th Annual Conference - Building and maintaining highways for the future - produced a substantial library of presentations on a very wide range of topics addressing the conference theme and relying in many cases on the most recent research available. The list of presentations is available here.
NZTA RR 453 (expected to be released in Nov. 2011) Revision and second edition of Trips and Parking Related to Land Use (Transfund NZ RR 209, 2001) and incorporating work reported in NZTA RR 374 (2009) comparing New Zealand and UK trips and parking rates.
NZTA RR 456 (Oct. 2011) improving rate-of-rotation design limits in crossfalls of road surfaces.
