Public transport node distance

There is no defined threshold for relevant public transport nodes, for the purposes of calculating the accessibility index (AI) score in HQM.

The HQM Transport Calculator tool gives increasingly more contribution to the AI score, the closer public transport nodes are to the assessed home. The assessor should use their judgement to include public transport nodes that may reasonably be used by occupants, in-practice.

This approach is taken in order to recognise the relative value of having access to public transport nodes, even if they are slightly beyond a clear-cut threshold or are well beyond walking distance but still may be used, even if it is to a lesser extent.
