For the purposes of this research, the weighting matrices used to assign the importance of each transportation mode and land use activity by age group was based on ‘best assumed’ assumptions. The weightings for land use activities considered not relevant to a particular age group, ie not able to be used by the age group, were given a weighting of zero.

If the comprehensive accessibility score proved useful, then research to identify both the potential mode split (behaviour) and availability of each of the transportation modes (ability) by age, would improve the weighting matrices used in the accessibility calculations. This would result in a better and more robust composite indicator.
