   📢 New preprint: Urban highways are barriers to social ties: https://arxiv.org/abs/2404.11596

   We overlay the highway network with a massive, geolocated online social network (Twitter 2012), and measure how social ties are impacted by highway segments. We find a strong barrier effect in all 50 considered US cities. See below - the red squares show that this effect is stronger for short distances.
