Tearing Down Highways is Good for Traffic, Environment, and People

- Adam Clare

Cars and car infrastructure cover North America like a bad rash. Car advocates like to argue that this is necessary and that we can’t possibly get rid of this rash because all the cars will become immobile and our economy will crash. The bad news is that the economy crashes even if you love cars, on the other hand, the really good news is that if you remove highways you can improve the economy by revitalizing local neighbourhoods.

Here’s a look at how tearing down highways is a good thing.

Though our transportation planners still operate from the orthodoxy that the best way to untangle traffic is to build more roads, doing so actually proves counterproductive in some cases. There is even a mathematical theorem to explain why: “The Braess Paradox” (which sounds rather like a Robert Ludlum title) established that the addition of extra capacity to a road network often results in increased congestion and longer travel times. The reason has to do with the complex effects of individual drivers all trying to optimize their routes. The Braess paradox is not just an arcane bit of theory either – it plays frequently in real world situation.

Likewise, there is the phenomenon of induced demand – or the “if you build it, they will come” effect. In short, fancy new roads encourage people to drive more miles, as well as seeding new sprawl-style development that shifts new users onto them.

Of course, improving congestion is not the main reason why a city would want to knock down a poorly planned highway–the reasons for that are plentiful, and might include improving citizen health, restoring the local environment, and energizing the regional economy. More efficient traffic flow is just a wonderful side benefit.

Sound dubious? Here are several examples of how three cities (and their drivers) have fared better after highways that should never have been built in the first place were taken down.

Times Square Goes Car-Free

New York City is famous for grid lock and horrendous traffic – but that’s the past. New York is really trying to green itself and become friendlier to sustainable forms of transportation. They are even going so far as to make times square car-free.

Vehicles are being barred between 42nd and 47th streets at Times Square and 33rd and 35th Streets at Herald Square.
City officials say the move will reduce pollution and pedestrian accidents and ease traffic flow in the area known as “crossroads of the world”.
…
“It’s good for traffic, it’s good for businesses and we think it is going to be great deal of fun,” city transport commissioner Janet Sadik-Khan said last week.

The symbolism of the financial heart of the American empire discouraging the use of the automobile will hopefully be noticed.

Norway May Ban Gasoline Cars by 2015

Norway is looking at the option to ban gasoline-powered cars to be sold in Norway. Under the proposal hybrids, flex-fuels, and biofuel powered cars can still be sold, which means that the plan is quite reasonable. I really hope they go forward with this plan – and hopefully other countries will follow.

“This is much more realistic than people think when they first hear about this proposal,” she told Reuters, defending a plan by her Socialist Left Party to outlaw sales of cars that run solely on fossil fuels in six years’ time.
…
Halvorsen denied that her proposal would undermine the economy — Norway is the world’s number six oil exporter.

“Not at all … we know that the world will be dependent on oil and gas for many decades ahead but we have to introduce new technologies and this is a proposal to support that,” she said.

Asked what she would say if she met the head of a big car producer such as General Motors, she said: “develop new and more environmentally friendly cars. And I know they are working on that question.”

Save the Economy by Removing Parking

Studies done in the last couple years disprove the myth that businesses need parking for customers or they’ll go out of business. The Spacing Wire has a post that looks at the studies and concludes that removing parking is good for business and making room for pedestrians or bike lanes improve livability.

A 2006 study of a Manhattan street (PDF) showed that, in fact, local businesses would benefit if parking was removed so that sidewalks could be widened. Last summer, on behalf of the Clean Air Partnership, Fred Sztabinski, then coordinator of the Toronto Coalition for Active Transportation (TCAT) (and sometime Spacing contributor), embarked on a similar exercise for a street in Toronto. The report, Bike Lanes, On-Street Parking and Business (PDF), has just been released. It’s a study of Bloor Street in the Annex (Huron to Palmerston), and it shows that removing parking for either bike lanes or a widened sidewalk would actually benefit local businesses in that area. The study surveyed both merchants and people walking along various parts of this stretch of Bloor during the month of July 2008.

The first part of the study shows that the majority of owners or managers of local businesses estimate that only a minority of their customers drive to their location, and also that they believe it would not harm, and might even benefit, their business if parking were removed to make space for either bikes or pedestrians.

The second part of the survey shows that the merchants are correct in their estimation of how their customers get to their store: 46% walk, 32% take transit, 12% cycle, and only 10% drive. Not surprisingly, walkers were also the most frequent visitors to the area, followed by cyclists, transit users, and finally drivers. Walkers also spent considerably more in the area than other types of customers. In other words, pedestrians were by far the best customers, followed by cyclists. Drivers, meanwhile, are the least frequent visitors and are low spenders.

Coconut Husks as Car Parts

- Adam Clare 2 Comments

Coconuts have a very hard shell that can be used in many different ways, a new suggestion by a team of researchers says that the really good part of the shell is the coconut’s husk which can be turned into car parts.

The approach has potential because coconuts are an abundant, renewable resource in all countries near the equator, including the Philippines, Indonesia and India. The husks are burned or thrown away, generating garbage. This is the first time that coconut fibers have been used to make these automotive products, said Walter Bradley, an engineering professor who is leading the project.

In Ghana, as one of Bradley’s students told him, the discarded husks pile up in mounds, creating a health hazard because they collect water where malaria-causing mosquitoes can breed.

“We are trying to turn trash into cash to help poor coconut farmers,” Bradley said, adding that the long-term goal is to increase demand for coconuts to millions of pounds, and thereby raise their market price.

Currently, there are about 11 million coconut farmers in the world making an average annual income of $500, he said.
