Evidence: In Vauban, "stores are placed a walk away, on a main street, rather than in malls along some distant highway" (Source 1). This is not only much more cost-efficient, but also convienent. This is saving both time and money, just like in Bogota where "parks and sports centers [] have bloomed throughout the city; uneven, pitted sidewalks have been replaced by broad, smooth sidewalks; rush-hour restrictions have dramatically cut traffic; and new restaurants and upscale shopping districts have cropped up" (Source 3). Not only does this help individual citizens and business owners, it helps the overall economy of the city as well.
