## A3 Basic trial

For the purposes of
this research report, a simple accessibility assessment was carried out using
version 1.6.0.0 of the Accession software (2008). The current version of the
software is version 1.6.2 (November 2012).

A basic road network
was created using a 3x3 matrix roughly the same size as Christchurch city. This
was done so the testing methodology could be compared to the calculations
undertaken in section 12.4 where basic accessibility calculations are
undertaken on a citywide basis in Christchurch. The 3x3 matrix overlaid on the
Christchurch city road centreline GIS layer is shown in figure A.3.

The matrix was then
populated with sample origins at each of the intersecting nodes and sample
destinations randomly clustered within each of the matrix cells and around each
origin (shown in figure A.4). All testing was performed on this very simplistic
network. Each of the matrix cells is titled with a letter for later reference.
