A spatial multi-criteria analysis method for the assessment of walkability to guide the design of interventions in urban crossings

In last decades, we assist to a constant, growing attention on urban walkability. Despite copious studies analyse the components of pedestrian spaces, little attention is given to road intersections, elements of interruption and obstacle of the walking paths. This study proposes a multi-criteria spatial analysis method of road intersections aimed to classify and prioritise actions for the implementation of pedestrian-oriented mobility policies. The method reveals the spatial elements to improve for enhancing walkability. An application to the city of Alghero revealed safety and comfort as the main factors that limit the propensity to walk and therefore need to be tackled through specific policies and interventions.
