15 minutes on a map and 15 minutes on foot are not the same 15 minutes 🕟
Perceived distance and metric distance diverge for very different reasons: a green corridor feels shorter, a windy or poorly lit stretch feels longer, even when the metres are identical. That gap decides who actually gets to use a city on foot, whether it's a child, an older resident, or someone who simply doesn't feel safe crossing a square at night.
As part of the DUT-CitySync initiative, alongside Kocaeli Büyükşehir Belediyesi, Shared City Foundation and Drees & Sommer, we're testing this directly: mapping parameters like green space, noise, wind, local commerce or road width against real pedestrian route choices, now extending across different urban cultures and contexts, with safety and sidewalk conditions coming next.
It's a reminder that the only works if it's measured from how people actually experience distance, not just how far it is on paper.
What would you add to the list of parameters that shape how far something feels? 🌍
Urban Mobility is (also) a social science – Part VI ! Here comes one of my favourite topics 😍 and the one I have been working closely on for the last few years. Does a really mean 15 minutes, everywhere, and for everyone? 📐We measure our paths in distance or t...
