Discussion

Measures of access to public transport such as PTAL should take account of what destinations can be reached via the local public transport node. Having access to a local bus stop is of little practical use for regular shopping if there is only one bus a week. The analysis of coverage of major public transport interchanges and of residential intensification is therefore much more useful for describing accessibility as a resident of a location would observe or understand it.

However all of these practical examples are much simpler than the theoretical concepts discussed earlier in this report and the applications in use in some countries. For example the basic examples above do not assess:

·         cumulative opportunities

·         all transport modes

·         complex geodemographic factors

·         continuous indicators.

However, although the basic examples above do not include all aspects of accessibility, they identify there is a latent demand within the transport planning community for considering transport from a non-traditional basis.
