This research project, carried out between 1995–1997, explores the personal travel characteristics of New Zealanders that have been recorded in various household interview surveys (HIS) carried out over the last 30 years.

A limited survey of roading practitioners was carried out to determine their opinion and needs with respect to communicating the findings of research about the properties of unbound aggregates.

The report develops and analyses proposals for output-based funding (OBF) for passenger transport, including implications of output-based contracts, and the use of subsidised deregulation.

The structural number (SN) of a road pavement is a method for describing the strength of a road pavement, in pavement deterioration models that are currently being calibrated for New Zealand road conditions.

This project developed market research techniques for deriving improved values for the unit benefit parameters specified by Transfund New Zealand for use in transport project evaluation throughout New Zealand.

Recognising the significance of scour (ie channel erosion, in all its forms) as a cause of bridge damage, a screening methodology for assessing and ranking New Zealand bridges in terms of their susceptibility to scour is presented.

A methodology has been developed, based on a study carried out in 1998–99, to assist in selecting optimum slope-failure preventive maintenance programmes for highways.

Geosynthetic-reinforced soils (GRS) have been found to be cost-effective compared to traditionally used retaining structures in specific situations.

A North American method for establishing an optimised slope-failure preventive maintenance programme for use by roading authorities has been identified and trialed by way of a case study, to determine its application to New Zealand roads.

Road networks are lifelines for the community and are essential for the economic and social well-being of New Zealand.
