An article from Complexity Science Hub highlights new research that reveals that the shape of cities has a significant impact on how people move around them. "Urbanization matters on many fronts, including sustainability: according to the International Energy Agency, cities account for roughly 75% of the global energy use and 70% of greenhouse gas emissions."

According to the article, "The results confirm that a compact and round city shape benefits travel efficiency. Elongated layouts that stretch along one axis increase travel distance in a non-linear fashion. Vienna, which was used as a reference for the model, is moderately elliptical and has an average travel distance of just under 10 km."

As the article notes, "Moderately pyramid-shaped profiles alone can lower travel distances by 20-25% compared to flat layouts, as taller buildings in the center bring potential origin and destination points closer together, thereby yielding substantial efficiency gains."

Moreover, "While city morphology is often subject to constraints (geographical, political, and those imposed by past decisions), the study shows that understanding the impact of city shapes creates opportunities for planning more equitable, resilient, and sustainable urban habitats."
