Horizontal curves have been recognised as a significant safety issue for many years, a more important factor than road width, vertical clearance or sight distance.

Investigations into the cohesive properties and oxidation resistance of an acid cured, epoxy modified open-graded porous asphalt (OGPA) were undertaken and an associated accelerated loading test carried out at Transit New Zealand’s CAPTIF facility.

The purpose of this research report was to review the use of congestion charging schemes in relation to the urban form of a selection of international cities.

Transit New Zealand Research Report No. 32, Site design for heavy vehicle facilities, is to assist architects and site planners in the design of on-site overall design and spatial arrangements for manoeuvring and parking vehicles.

Research was carried out between 2005 and 2006 to determine if there were benefits or disbenefits associated with sealing unsealed roads, and if so, to determine a procedure for calculating the accident savings (or costs).

As toll roads and other forms of road pricing become of more interest to road controlling authorities in New Zealand, the importance of providing robust forecasts of motorists’ responses to tolls increases.

This project aimed to develop analytical methods for assessing energy risks due to a peak and decline in global oil production.

Research carried out in 2001 examined the causes of cycle crashes on roads, footpaths, and cycle ways throughout New Zealand, through a survey of injured cyclists.

Dipentene (a solvent derived from radiata pine) and toluene were investigated as alternatives to the ozone-depleting methyl chloroform used in bitumen content determinations of asphalt.
