Pedestrian zone

Pedestrian zones (also known as auto-free zones and car-free zones, as pedestrian precincts in British English, and as pedestrian malls in the United States and Australia) are areas of a city or town restricted to use by people on foot or human-powered transport such as bicycles, with non-emergency motor traffic not allowed. Converting a street or an area to pedestrian-only use is called pedestrianisation.

Pedestrianisation usually aims to provide better accessibility and mobility for pedestrians, to enhance the amount of shopping and other business activities in the area or to improve the attractiveness of the local environment in terms of aesthetics, air pollution, noise and crashes involving motor vehicles with pedestrians. In some cases, motor traffic in surrounding areas increases, as it is displaced rather than replaced. Nonetheless, pedestrianisation schemes are often associated with significant falls in local air and noise pollution and in accidents, and frequently with increased retail turnover and increased property values locally.

A car-free development generally implies a large-scale pedestrianised area that relies on modes of transport other than the car, while pedestrian zones may vary in size from a single square to entire districts, but with highly variable degrees of dependence on cars for their broader transport links.

Pedestrian zones have a great variety of approaches to human-powered vehicles such as bicycles, inline skates, skateboards and kick scooters. Some have a total ban on anything with wheels, others ban certain categories, others segregate the human-powered wheels from foot traffic, and others still have no rules at all. Many Middle Eastern kasbahs have no motorized traffic, but use donkey- or hand-carts to carry goods.

The idea of separating pedestrians from wheeled traffic is an old one, dating back at least to the Renaissance. However, the earliest modern implementation of the idea in cities seems to date from about 1800, when the first covered shopping arcade was opened in Paris. Separated shopping arcades were constructed throughout Europe in the 19th century, precursors of modern shopping malls. A number of architects and city planners, including Joseph Paxton, Ebenezer Howard, and Clarence Stein, in the 19th and early 20th centuries proposed plans to separate pedestrians from traffic in various new developments.

The first "pedestrianisation" of an existing street seems to have taken place "around 1929" in Essen, Germany. This was in Limbecker Straße, a very narrow shopping street that could not accommodate both vehicular and pedestrian traffic. Two other German cities followed this model in the early 1930s, but the idea was not seen outside Germany. Following the devastation of the Second World War a number of European cities implemented plans to pedestrianise city streets, although usually on a largely ad hoc basis, through the early 1950s, with little landscaping or planning. By 1955 twenty-one German cities had closed at least one street to automobile traffic, although only four were "true" pedestrian streets, designed for the purpose. At this time pedestrianisation was not seen as a traffic restraint policy, but rather as a complement^{[clarification needed]} to customers who would arrive by car in a city centre.

Pedestrianisation was also common in the United States during the 1950s and 60s as downtown businesses attempted to compete with new suburban shopping malls. However, most of these initiatives were not successful in the long term, and about 90% have been changed back to motorised areas.

In the United States, several pedestrian zones in major tourist areas were successful, such as the renovation of the mall in Santa Monica on Los Angeles' Westside and its relaunch as the Third Street Promenade; the creation of the covered, pedestrian Fremont Street Experience in Downtown Las Vegas; the revival of East 4th Street in Downtown Cleveland; and the new pedestrian zone created in the mid-2010s in New York City including along Broadway (the street) and around Times Square.
