Incorporating Network-based Built Environmental Attributes of Walkability and Cyclability into Accessibility Modelling: A Pilot Study for Greater Manchester

Accessibility is a key instrument for assessing active mobility. However, accessibility measures often suffer from biases due to spatial aggregation, isochrones with arbitrary cut-offs, and distance-based cost functions that ignore the route conditions. Previous literature has addressed these issues individually, but not holistically. This study applies the MATSim framework to efficiently route between billions of origin-destination pairs to calculate fully disaggregate Hansen accessibilities using cost functions sensitive to network quality. With examples of greenspace and foodstore accessibility, we demonstrate the potential of this method for providing policy-relevant insight into the suitability of the built environment for active travel.
