Densely connected walking networks offer the best outcomes for calculating walking accessibility. When it is necessary to make changes to walking networks, it’s important to understand the effect that the changes could have on peoples’ ability to reach destinations on foot. Hamilton City Council asked us to model the possible consequences of a number of network changes under various scenarios to access how best to alter walking links for their ratepayers.
We modelled household accessibility under the existing HCC walking network, and then again for each of the scenarios proposed by Hamilton City Council. Accessibility modelling involves measuring peoples’ ability to reach desired destinations within a specified timeframe using a specific mode of transport. The results for each of the proposed scenarios could then be compared to the original network, to see how accessibility had been affected.
We produced a series of maps for the council, detailing each of the different scenarios and showing how accessibility had changed in each instance. The output maps were clearly symbolized to show where accessibility had decreased, and where it was improving. These maps helped the council see and understand the potential effects of any network changes.
