A1 Background

This section describes a trial of the Accession software package in New Zealand. The main focus was to evaluate the suitability of using Accession in New Zealand given the topical interest in this product at the time. This assessment was undertaken in 2008.

The trial provides a brief overview of Accession’s capabilities but it does not attempt to describe all the settings and model parameters available within the software or the software usability.

The Accession software was originally developed by MVA, a UK transportation consultancy, to automate accessibility calculations for local authorities. Accession was one of the software packages developed with funding from the UK Department for Transport and is a commercial product now distributed by Citilabs.
