Research description

There is a lack of streamlined walkability evaluation in Asian cities for its dense urban morphology and three-dimensional (3D) walking system, especially in cities where pedestrians are separated from vehicles by footbridges or underpasses. We constructed a walkability scoring system in Hong Kong and investigated why and how a 3D pedestrian network makes a difference in walkability scoring. Results show that scores are on average 92% higher when calculated with the pedestrian network. Our citywide analysis on walkability scores challenges existing walkability evaluations for potential inaccurate data usage. We provide an open-source protocol that enables a wider, simpler, and more accurate application of walkability in Asian cities.
