This paper presents a map that demonstrates how a pedestrian network can be used to improve the accuracy of these results and model the effect of gradient and demographics on walk speed. A bespoke GIS model was developed to undertake the assessment, which is explained along with the key assumptions made. The model was used to assess pedestrian access levels from five proposed development sites in the West Northamptonshire area to the key local facilities. The results quantified access using defined threshold journey times to provide the percentage of dwellings within this limit. This helped West Northamptonshire Development Corporation to consider the specific pedestrian access issues that each site may have, which forms part of their process of delivering sustainable development. The model developed co... |
