For plenty years, many popular mountain resorts have seen largely uncontrolled development consisting of the multiplication of archetypal chalet-style houses. This is usually accompanied by roadbuilding for private cars. In order to protect these tourist destinations and their natural environs from further uncontrolled development, the author investigates different settlement structures such as Andermatt, Avoriaz, Verbier, Zermatt,and Whistler-Blackcomb. On the basis of detailed graphical analyses, she develops groundbreaking strategies for urban densification and suitable mobility management, which can also be transferred to other tourist areas.
