Further research

There are many refinements that can be made to the methodology for calculating the various accessibility scores. This section outlines some possible refinements for further work. In the UK there is recognition that further research is needed to develop scores that can be used in policy but this research showed that useful scores can be calculated to apply in practice. In the short term the more robust accessibility indicators will continue to be the most transparent travel time measures by trip purpose and traveller group. However further work on developing composite accessibility scores could enhance the accessibility planning process.
