This report follows on from Opus Report 95-526264.01, which recommends a test procedure for New Zealand basecourse materials.

The correlation between road roughness, as measured by the NAASRA roughness meter, and the profile factor, measured by profile beams, was investigated between 1992 and 1995.

Experimental and theoretical studies of the properties and performance of electromagnetic loops and feeder lines used in road vehicle detections systems were carried out to determine causes of erratic behaviour of loops, and to improve their performa…

A study was made of proposed means by which water can enter chipseals surfaces and induce flushing.

Over the past decade, the longitudinal profiling of wheelpaths has become routine with the advent of laser-based high-speed monitoring systems. A study was undertaken in 1998 to investigate the suitability of latest generation spectral analysis metho…

Potential economic disbenefits of dust emission from unsealed roads impact on crop production, animal food supply and health, accident potential, property values and maintenance costs, vehicle operating costs and personal health.

This report develops project evaluation procedures to incorporate risk assessment of road link reliabilities.

It is difficult to obtain reasonably accurate information on the demand for public transport (PT) in New Zealand cities.

This study, carried out in 1998, investigates hazards that have the potential to close the Desert Road, which traverses for some 60 km the Central Volcanic Plateau of the North Island, New Zealand, at around 1000 m altitude.

This project aimed to provide guidance on the development, specification and implementation of parking restraint policies for the major urban centres in New Zealand.
