SLOWTH: por que es tan importante (y tan facil) ‘ralentizar’ el tráfico en ciudades

vía SLOWTH: Or why it is so very important (and so very easy) to slow down traffic in cities | World Streets: The Politics of Transport in Cities.

Es postura consecuente de esta revista, que mucho de lo malo con nuestros actuales arreglos de transportación en ciudades se aliviaría en gran medida si encontrámos la manera de disminuir la velocidad. Una postura firme – no tan difícil de hacer. Póngase cómodo y eche un vistazo.

On “slowth”:

El usar una palabra extraña por no decir fea como “slowth” es un intento de llamar la atención sobre la importancia de disminuir la velocidad del tráfico en las ciudades, y por qué, siendo tan buena idea, puede resultar contraproducente. Sólo usted, amigo lector, puede tomar esa decisión. Pero espero que me tenga paciencia, al menos por el momento, y si no se puede proponer algo mejor, por ahora, sería fantástico que con pluma en mano completara y mejorara lo que aquí sigue sobre este tema importante.

Here is an entry we made some time back in Wikipedia on the concept of slowth to get the ball rolling. Have a look and if you are up to it, please complete and improve.

Slowth

* From Wikipedia, the free encyclopedia – http://en.wikipedia.org/wiki/Slowth

Slowth is a new mobility transport planning concept, usually deployed in congested urban environments, where transport is calibrated for lower top speeds, but the result is shorter overall travel times across the entire system.[1]

The concept of slowth is sometimes compared to the story of The Tortoise and the Hare; the paradoxical notion that slowing the top speeds of transport will when properly engineered allow more people to get to their destinations more quickly. An example is that where there is sufficient traffic congestion, a bicycle may get to its destination more quickly than say a Ferrari. When a city adopts a policy of slowth, the top speeds will be lower, but congestion decreases because the slower speeds result in steadier traffic flow.[1]

This is a powerful model which urban planners and traffic engineers, with a few notable exceptions, are only recently starting to take seriously. An important new mobility concept, it is also referred to as “slow transport.”

In the report “Speed Control and Transport Policy” (Chapter 10, on speed limits in towns, Policy Studies Institute, 1996) Mayer Hillman and Stephen Plowden describe an experiment in Växjö, a Swedish town of 70,000, which showed very small time penalties arising from some fairly substantial speed reductions at 20 junctions. The Swedish researchers used the results to simulate what would happen if similar speed-reducing measures were introduced at 111 junctions throughout the town and concluded that there would probably be a small net time saving.[2]

In recent years it has gotten steadily increasing attention both in the literature but above all as part of the on-street sustainable transport strategies of a growing number of leading programs and projects around the world (Here is a first listing which we hope you will improve and complete).

Again, please consider adding to and improving this article.

And in closing consider this:

A bare five miles per hour over the speed limit on a city street, and . . .
