This report outlines the direct and indirect benefits of High Productivity Vehicles (HPV) in Australia. Direct benefits examined include safety, productivity, fuel and environmental savings. An attempt has also been made to estimate indirect…

This report has developed a new index, the Heavy Vehicle Roughness Band Index (HVRBI), as a measure of ride quality for heavy vehicles. The HVRBI is intended for use by road asset managers as a trigger to initiate pavement intervention works…

The purpose of this report is to identify, review and compile existing literature on small travel time savings, and the current practice of considering the notion of small travel time savings in project evaluation. The review discusses both work and…

The purpose of this document is to develop and present a catalogue/checklist of items, which can be employed by transport agencies and their practitioners and consultants to properly document the methodology, data, analysis and results of project…

The project includes a literature review of speed-flow curves, review of practices across jurisdictions, implications of speed-flow curves for project appraisal, harmonisation of speed-flow curves. A range of speed-flow curve relationships is…

This report introduces key methodologies and the associated challenges with regards to defining and measuring travel time reliability, in particular, for improving the valuation of travel time in project appraisal by Australian jurisdictions.

This document is provided for the benefit of transport planners and managers. It reviews and summarises the Best Practice Cost Estimation Standard (BPCES) developed by Evans and Peck and is applicable to any transport project for which Australian…
