This report describes a study, carried out in 2006–2007, of the potential toxicity to the environment (ecotoxicity) of cationic bitumen emulsions used for chipsealing (surface dressing) in New Zealand.

The New Zealand government is seeking to reduce the number of road crashes that arise from driver fatigue in this country.

Rut depths are permanent deformations of the pavement structure, and an important indicator of the structural integrity of the pavement as well as having an impact on road user safety.

Funding for new cycling facilities is based on cost benefit ratios, which are dependent on the predicted future demand by cyclists.

Bridge inspection and maintenance management systems used in New Zealand and overseas have been identified and reviewed.

A cycle train is similar in approach to the ‘walking school bus’ – adult volunteer ‘conductors’ cycle along a set route to school, collecting children from designated ‘train stops’ along the way.

Conducted in 2005, this study evaluates a case-control design of contrasts between walkers and drivers to address factors influencing the uptake of walking as a mode choice.

This report examines the characteristics of park and ride (P&R) useage and suggests demand modelling methodologies based on these characteristics for changes in demand at existing sites, and estimation of demand at new sites.

This research project develops best practice guidelines for carrying out transport impact assessments (TIA) of development proposals in New Zealand.

There are many techniques for restoring pavement surface microtexture after levels have become deficient.
