The methodology for calculating comprehensive accessibility scores outlined in this report includes weighting of the scores based on the age breakdown of the population, as age is considered an important determinant for the relative opportunity of an activity. Many other demographic variables are also determinants of opportunity including:
· car ownership and availability
· household income
· mobility and/or sight impairment.
The inclusion of the above factors would further refine the accessibility scores. Alternatively a methodology similar, but improved, to determine ‘need’ such as that proposed by Currie and Senbergs (2007) would be useful.
