Abstract
Objective: This paper develops a way of incorporating steepness into ‘ped-shed’ analyses to provide a more realistic view of urban walkability. The methodology is tested on the street network in Milton, north Glasgow, but presented such that it could be applied more widely. Method: Elevation data is added to existing and proposed street networks in Milton which enables a calculation of average walking speed per segment to be made taking into account steepness. The networks are then run through ArcGIS’s Network Analysis extension, using time (adjusted for uphill and downhill slope) as impedance. Results: ‘Real’ walkable 10-minute roundtrip catchments around neigh...
