Aspectos Medibles de la Caminabilidad

Características medibles del “Atractivo de Caminar” proporcionan indicadores de la caminabilidad de un paisaje callejero

Las calles y los paisajes callejeros que las rodean tienen varias cosas medibles que nos pueden decir qué estandard de Atractivo de Caminar (Walk Appeal) ofrece la calle. En este post vamos a ver las cosas que se pueden medir, luego hablaremos de las cosas que no se pueden medir.

Ve los Cambios

Mientras más frecuentemente cambies la vista de alguien al caminar, mejor lo entretienes. Entretener a quienes están caminando significa que probablemente continuarán caminando. Dos simples movimientos geométricos cambian las vistas más rápidamente que cualquier otra cosa: Mientras más cerca se encuentre la pared del edificio de la acera, más rápidamente cambiará tu vision de cualquier punto dado. Y cuanto más estrecho sea el edificio, más rápidamente pasarás frente a él. Las calles principales con tiendas estrechas como en la foto de arriba hacen un trabajo excelente en ambos aspectos.

Recinto de la calle

Las mejores calles del mundo tienen paredes de edificios a ambos lados que son tan altos como el espacio entre las fachadas de los edificios. Técnicamente hablando, tienen un cercamiento de calle de 1:1 o mayor. Una calle con buen cercamiento se siente como un salón al aire libre, y la gente prefiere salones al aire libre que calles con poco cercamiento que sólo sangran dentro del paisaje. Un cercamiento de 1:1 o mayor es más fácil en Europa porque sus calles son mas estrechas. Trabajamos duro en los E.U.A. para lograr cercamientos de 1:3 en la mayoría de los lugares, pero podemos aun exceder 1:1 de vez en cuando como en la calle 14 en Washington DC mostrada arriba.

Ventana de Vision

There are two prime measurements of Window of View as well: horizontally along the sidewalk, and height. The ideal percentage of glass at eye level along the sidewalk is around 70%. Why not go all the way to 100%? Wouldn’t that be more interesting? While you would have slightly more of a view into the interior of the building, 100% glass is butt-glazed glass as far as the eye can see, undifferentiated by window frames, pilasters, and other building elements. Having too little glass is a bigger error, as there are few things more boring if you’re walking than passing along a blank building wall.

The minimum window sill height is 8 inches. Glass run all the way to the sidewalk is a bad idea because the base of the wall is subject to more damage and should be built of things that can be patched and repainted. Glass fails completely on both counts. The maximum sill height should be 30 inches, or roughly the height of a restaurant dining table. The minimum head height should be 8 feet above the sidewalk, although taller window heads can be striking.

Shelter

The best building fronts shelter people who are walking from the elements, at least at the front door. In rainy or hot and sunny climates, near-continuous shelter is much better. Shelter can be composed of fabric awnings as shown here, or it can also be made of hard awnings, porch roofs, galleries, or arcades. If a place has an existing tradition of shelter elements such as the galleries of New Orleans, consider reinforcing that tradition.

Goals in the Middle Distance

Things that border the sidewalk are the most important measurable means of enhancing Walk Appeal, but they inevitably stutter or fade somewhere along a street. With no immediate reason to continue, people walking might turn back. But if there is a goal in the middle distance, that may entice them across those less excellent stretches in the streetscape.

It is important to note that goals in the far distance, like a mountain, aren’t nearly so effective because you don’t have the hope of walking all the way there. But goals in the middle distance (1 block to 2 miles) are places you might walk to. Because they’re in the middle distance, you don’t have to walk too far until their perspective changes visibly. This continues to reel you in as you walk closer.

Goals in the middle distance should be fairly tall, otherwise things in the foreground can easily block your view of them. Often, as pictured above, they might be tall buildings or even towers. They can also be uninhabited elements such as obelisks. FWIW, town planning geeks call goals in the middle distance “terminated vistas.”

Turning the Corner

Even if you do a great job with everything we’ve talked about so far, you could still screw up Walk Appeal when you turn the corner. If you’re walking on a really good front street (like the Main Street leading off to the left here) and turn off on a side street, you’ll typically be facing the side of a building (hence “side street.”) Sides of buildings are often longer than the fronts on commercial streets because commercial real estate is often valued by the “front foot.” Longer building faces are usually more boring faces. This is compounded by the fact that it’s really easy to leave side walls of commercial buildings nearly blank so you can put merchandise shelving against them. You therefore have to work at it to do as good a job as the building above did on its side street (the right side.) Without good side street walking, people don’t walk to the Main Street nearly so much.

As I said Wednesday, we’ll look at the Walk Appeal things that can’t be measured next. After that, we’ll explore some really stunning economic development implications of varying degrees of Walk Appeal.
