“…Various versions of these schemes have been found in numerous European cities, such as "share-spaces", or "car-free development" in the United Kingdom [23,24], "woonerf" in the Netherlands [25], "car-free or car-reduced housing areas" in the Freiburg-Vauban, "Kiez blocks" in Germany [26,27] and Vienna [28], and "micro-districts" in Russia [29]. This concept has also been explored in various urban contexts, such as in China (Asia) [30], Abu Dhabi (Middle East) [31], Panama [32], and the United States of America [33]. However, the superblocks being deployed in Barcelona, Spain, are the largest in size, covering the entire city core (100 km 2 ), with 503 superblocks planned and nine implemented or in progress [10,34,35].…”
