Listen to part of a lecture in a city planning class.

In the last 50 years or so, many American cities have had difficulty in maintaining a successful retail environment. Business owners in the city centers, or, uh, the downtown areas, have experienced some financial losses because of a steady movement of people out of the cities and into the suburbs. In general, downtown areas just don"t have that many residential areas; uh, not that many people live there. So, what have city planners decided to do about it? Well, one way they"ve come up with some ways to attract more people to shop downtown was by creating pedestrian molls.

Now, what is a pedestrian mall? It"s a pretty simple concept, really. It"s essentially, um, an outdoor shopping area designed just for people on foot. And—uh, well, unlike many other shopping malls that are built in the suburbs nowadays—these pedestrian malls are typically located in the downtown area of the city and, well, they have features like wide sidewalks, comfortable outdoor seating, and, uh, maybe even "fountains and, you know, art.
Uh, there are variations on this model, of course, but the common denominator is always the idea of-of creating a shopping space that will get people to shop in the city without needing their cars. So I"m sure you can see how having an area that"s off-limits to automobile traffic would be ideal for a heavily populated city, where, uh, well, the streets would otherwise be bustling with noisy, unpleasant traffic congestion.
Now, the concept, which originated in Europe, was adopted by American city planners in the late 1950"s. And since then, a number of United States cities have created pedestrian malls, and many of them have been highly successful. So what have city planners learned about making these malls succeed? Well, there are two critical factors to consider when creating a pedestrian mall: location and design. Both of which are equally important.
Now, let"s start with the location. In choosing a specific location for a pedestrian mall, there are, in fact, two considerations: proximity to potential customers—uh, that"s we would call a "customer base"—and accessibility to public transportation, which we"ll get to in just a moment. Now, for a customer base, eh, the most obvious example would be a large office building—since the employees could theoretically go shopping after work or during their lunch hour, right? Uh, another really good example is a convention center, which typically has a hotel and large meeting spaces to draw visitors to the city for-for major business conferences and events. Uh, but ideally, the pedestrian mall would be used by local residents, not just people working in the city or-or visiting the area. So that"s where access to public transportation comes in. Either, um, either the designers plan to locate the mall near a central transportation hub—uh, like a bus terminal, a major train, or subway station or they work with city officials to create sufficient parking areas not too far from the mall. W-Which makes sense, because if people can"t drive into the mall area, well, then they need to have easy access to it.
OK. So that"s location, but-but what about design? Well, design doesn"t necessarily include things like sculptures, or decorative walkways, or-or even eye-catching window displays—you-you know—art...Although, I"d be the first to admit those things are aesthetically appealing...However, visually pleasing sights, well, they"re not a part of the pedestrian mall design that-that matter the most. The key consideration is a compact and convenient layout—uh, one which allows pedestrians to walk from-from one end of the mall to the other in just a few minutes...so they can get to the major stores, restaurants, and-and other central places, eh, without having to take more than one or two turns. Now, this takes careful and creative planning.
Eh, but, now, what if one ingredient to this planning recipe is missing? There could quite possibly be long-lasting effects. And, eh, I think a good example is the pedestrian mall in Louisville, Kentucky, for instance.
