Acceptable comprehensive accessibility scores

There are occasions when comprehensive accessibility scores can be usefully combined to show comparisons of accessibility between locations based on demographics. However, for a comprehensive accessibility score or threshold indicator to be incorporated into government policy, more work is needed to understand the performance of accessibility and the sensitivity of the indicator to change. This is because comprehensive accessibility scores, similar to other aggregate indicators, can hide more than they reveal.

Threshold indicators on the other hand may be more appropriate for providing a focus for activity as a highly segmented people-focused approach. Acceptability of an accessibility indicator could vary depending on location, for example rural compared with urban areas, and other factors. Such approaches have been used in The Netherlands, eg the 1989 ABC planning policy (Ebels 1995) although in that example, the policy proved difficult to maintain and has fallen into disuse.

Even so, the setting of accessibility targets could be done in a similar way to how larger communities define acceptable levels of service, such as through national standard setting, or medium to smaller communities set through district or long-term council community plans.
