I was interested in Yoos and James’ interpretation of and “urbanism” of HK by its growing population. As they explained pedestrian systems as “thickening”, I immediately thought up of “elevations”. I think HK has preserved the old, yet developed cities, reacting to the vastly growing population in the most efficient way. The most well-known reaction for this could be the escalators, footbridges, stairs in the middle of the roads: “on-demand planning”. Sometimes, as a foreigner, I would think, why would they have so many footbridges and escalators in HK? But now to think of it, that means HK has such a sophisticated pedestrian system that they have thickened, elevated, interiorized walkways that we, as pedestrians, can technically walk anywhere on foot. As a foreigner, that absolutely blows my mind. It’s making tight interactions within people, making pedestrians most comfortable, but not restricting nor hindering the traffic (both cars and humans).
