Articulo: Livability to Become Requirement in Federal Transportation Policy

Transit can have a broad impact on community livability, like this bus stop in Los Angeles, which catalyzed nearby development after simple improvements were made


For years, large-scale transit projects submitted for funding in the United States have been evaluated primarily on cost and the amount of time they save commuters. While these criteria may seem perfectly reasonable, the cheapest, quickest transit route is not necessarily the one that best serves communities along the way.

Two weeks ago, the Obama Administration made a dramatic policy shift on how to evaluate major transportation projects. In a statement on January 13th, U.S Transportation Secretary Ray LaHood announced that, “We want to base our decisions on how much transit helps the environment, how much it improves development opportunities and how it makes our communities better places to live.”

Wow! For many years, Project for Public Spaces has advocated for greater community involvement in the transportation planning process, beginning with our 1997 publication, “The Role of Transit in Creating Livable Metropolitan Communities.” Reflecting on this report, Senior Vice President Steve Davies noted, “We first had to define what livability was, because it means different things to different people. It was through this process that we first developed the place diagram, which has become one of PPS’ most influential tools.”

Twelve years later, a key theme of the report–transportation projects can positively affect the livability of communities–is poised to become a part of federal policy. PPS.org sat down with PPS Vice President Cynthia Nikitin to gauge her reaction to this exciting news and discuss the implications for the transportation planning process in the future.

Articulo: Los venezolanos están entre los más obesos del mundo

Seremos el país latinoamericano con mayor índice de sobrepeso en 2020

La urbanización de las ciudades aleja de las dietas (Nicola Rocco/archivo)

SANTIAGO DE CHILE.- Los índices de obesidad en la población mayor de 15 años aumentaron en América Latina, especialmente en México, Venezuela y Guatemala, dijo a DPA la consultora de negocios Euromonitor International.

El caso mexicano es el más notorio. En 1980 tenía un índice de 17,1% de su población obesa y aumentó a 31,8% en 2009.

Los países latinoamericanos que le siguen son "Venezuela, con 29,6%; Guatemala, con 27,5%, y Bolivia, con 27,3%", manifestó la consultora. De hecho, estos países ingresaron al grupo de los diez más obesos a escala mundial, que está liderado por Kuwait con 42,2% de su población sobre 15 años calificada como obesa en 2009. Estos resultados reflejaron un aumento del acceso de los países latinoamericanos a comidas más calóricas gracias al desarrollo de las cadenas de comida rápida, que se convierte en una opción de alimentos de bajo costo para familias más pobres.

Además, Euromonitor reconoció que la mayor urbanización de las ciudades generó un cambio de hábitos en las personas y las aleja de dietas tradicionales más equilibradas y del ejercicio.

"La obesidad genera costos a los gobiernos, ya que debe ser tratada a través del sistema de salud estatal (...) Cuando los índices aumentan, el gobierno pierde los impuestos que recibe de quienes quedan imposibilitados de trabajar", sostuvo Euromonitor.

Aunque los niveles de obesidad en Latinoamérica crecieron más lentamente que en países desarrollados como Estados Unidos (que cuenta con un 38,7% de población mayor de 15 años obesa), las proyecciones no son auspiciosas.

"Para el año 2020 los seis países más obesos en América Latina serán: Venezuela, Guatemala, Uruguay, Costa Rica, República Dominicana y México", señaló la consultora.

Una persona es considerada obesa cuando su índice de masa corporal está sobre 30, ya que lo normal y sano fluctúa entre 18,5 y 24,9. La obesidad no es considerada como enfermedad en sí misma, pero tiene efectos considerables en la salud, derivando a problemas como diabetes, enfermedades de corazón, de riñones e hígado.

Imagenes: Packed Streets Have a City of Walkers Looking Skyward for Answers

Articulo: Packed Streets Have a City of Walkers Looking Skyward for Answers

MUMBAI—Mumbai's muddled streets are too packed to walk through, so India's commercial capital has come up with a solution. Uplift the masses—not in some fuzzy metaphysical way, but on "skywalks" made of steel.

Skywalks, India's Sidewalks in the Sky

2:39

The streets in the crowded megacity of Mumbai are running out of space for pedestrians, so the city has come up with a lofty solution: Elevated skywalks. WSJ's Eric Bellman reports.

Most streets here have no footpaths. The sidewalks that do exist are bursting from a gridlock of walkers, street vendors and squatters. The scrum has become even pushier recently as hundreds of thousands migrate to this city of nearly 18 million people for jobs created by its economic expansion. Success has also led to an unprecedented number of cars and motorcycles on the road.

To lift the pedestrians that power this city above the fray, Mumbai is building more than 50 elevated walkways. The skywalks will sprout from train stations across the city and snake over the traffic for up to two miles to create a pedestrian express lane.

Shubhangi Ambardekar, a 47-year-old bank employee, used to splurge on an auto rickshaw every workday to avoid the mess on the roads around Bandra train station in central Mumbai. Rickshaws don't like taking such short trips so she would often have to wait 20 minutes before one would take her. Today she uses the new Bandra Station skywalk, strolling two floors above the cacophony. She saves the fare and arrives at work relaxed.

Mumbai Pedestrians to Get Raised Paths

Michael Rubenstein for The Wall Street Journal

Pedestrians walk to work on a skywalk connecting the Bandra train station and the Bandra Kurla Complex in Mumbai last month.

"There's security, it's clean and we get fresh air too," she said on a walk home from work.

The skywalk Ms. Ambardekar uses was the first the city finished last year. Locals have dubbed the bright, twisting structure the "Yellow Caterpillar." At a height of around 20 feet, it meanders for around a mile, delivering commuters to one of Mumbai's many new office parks.

The fate of the city's foot soldiers is crucial because close to 60% of the trips made here are on foot. That makes this one of the most pedestrian-powered metropolises in the world. Until now, however, pedestrians have been largely ignored.

Some Mumbaikars, as citizens are known, aren't happy. Retailers say they are losing business while residents say skywalks block views, allow pedestrians to peek into private homes and are just as likely to be taken over by homeless families and shopless vendors as the sidewalks.

"Whether you have skywalks or not, the problems will remain the same," says Ashok Ravat, head of the Mahim Skywalk Protest Committee, which was created to block a long skywalk scheduled to twist through his neighborhood in central Mumbai. "This is another huge mistake."

Still, something had to be done, city planners say. The road under the Yellow Caterpillar, like station roads across the city, is an obstacle course through a minefield. Commuters spill down the Bandra Station steps and into a knot of three-wheeled auto rickshaws, buses and trucks on the street below. The closest thing to a sidewalk here is a patch of dirt next to a crud-filled creek. Hundreds of commuters walk in the street, dodging vehicles as they go.

Sidewalk Squeeze

See what's squeezing the sidewalk around Mahim.

On the way to the nearby business park—home of Citigroup's main India office and the National Stock Exchange—they pass through a slum. The roadside is occupied by small shops, families living in plastic-tarp homes, parked motorcycles and goats rooting through garbage. The tiny stretch of sidewalk that eventually emerges about five blocks from the station is cut short by the fence of a small neighborhood police station built directly on top of it.

Then pedestrians have to find their way across an off-ramp of Mumbai's busiest highway. There is a functioning traffic signal and even a policeman at the corner, but drivers often ignore both.

The obvious solution of widening the sidewalks just isn't an option. Mumbai, formerly known as Bombay, is a thin spit of land bound on three sides by the Arabian Sea. Moving buildings to widen roads is next to impossible thanks to tough tenancy laws. Courts and politicians sensitive to the needs of the micro-entrepreneur make it difficult to move illegal street vendors.

"We clear them and they just come back," says Ashwini Bhide, joint metropolitan commissioner of the Mumbai Municipal Regional Development Authority. "That's why we thought, 'Let's create some additional space on the road by going elevated.' "

Skywalks are quick to build, relatively inexpensive and only require land the city already controls. The projected bill for the 50-plus skywalks is around $300 million. The city expects to recover most of that cost by selling advertising space on them.

While Hong Kong has a network of elevated walkways and Minnesota has its "skyway" system to shelter commuters from harsh winters, Mumbai city planners say they came up with this idea on their own.

[SKYWALK]

A MUMBAI SKYWALK

"It was a local solution for a local problem," says Ms. Bhide. "Because of a paucity of space and such a short supply of land there is no other alternative."

Building the perfect skywalk, however, hasn't been easy. While the walkways run over government roads, there still often isn't space on the ground to plant enough supporting columns. Longer stretches between columns mean the city has to spend more on stronger, lighter materials and thicker columns. Commuters found the early skywalks too boxy and bright, so new ones use curved roofs, dark colors and chrome.

When engineers started digging to build the foundations, they found the chaos on the street continues underground. A few feet down, they ran into uncharted water, electricity and phone lines as well as sewers, forcing them to redesign whole skywalks. Trying to get the city water authorities or state-run telephone company to shift infrastructure would take too long.

Engineering difficulties and neighborhood opposition have blocked six planned skywalks and could stop more, city planners say. But they will continue building them because the streets are getting worse everyday. The city has hired armed guards to keep skywalks clear and the response from commuters has been largely positive.

Ms. Ambardekar, the commuter, uses her neighborhood skywalk even on her days off.

"Our city is so crowded we don't have a place to walk or exercise," she says. "My friend and I come up to the skywalk for our evening walks."

Video: Mercaderes Street, Arequipa, Peru

Mercaderes Street, Arequipa, Peru from EMBARQ Network on Vimeo.

Over the summer I had the opportunity to visit Arequipa, Peru’s southern-most major city, and see first hand all the work that the city and regional governments have done to make the city more pedestrian friendly. So far, Arequipa has completed one major project, the pedestrianization of Mercaderes, the main commercial drag in the heart of the city. This street was once jam packed with cars, many of which were old and belched out dirty fumes that darkened the air.

Now, the street is remarkably clean and quiet. It’s a pleasant place to stroll, go shopping, and people watch. I talked with a few pedestrians and merchants whose stores lined the street and they all agreed that Mercaderes was much improved without the car traffic. Some even suggested that more streets in the city should ban cars and become more like Mercaderes.

In fact, the city is planning to do exactly that. Its goal is to connect several of the more important streets in the city’s historic downtown, a UNESCO world heritage site, by making them pedestrian only. It also plans to replace the city’s chaotic transit system of small vans and buses with a bus rapid transit system that has fixed stops and bus-exclusive lanes. If the transit project goes through, it will be a boon for city residents and will dramatically improve the quality of life for people who live in Arequipa.
