From Innovative Street Layouts to the Fight against Urban Motorways in the United States
The quality and design of streets have always been important issues for walking and more details on this are provided in the ﬁnal chapter. Some speciﬁc street layouts are more popular with pedestrians than others. Narrow medieval streets, crooked lanes and numerous irregular squares made walking interesting and easy when only a few vehicles could access them because the streets were too narrow. However, historically these streets were mostly ﬁlthy and rich people hardly used them. This changed during the 19th century when main drains were constructed and most street areas could be converted into cleaner space.
