Car-Addicted LA is Getting on the Bike-Train

Los Angeles is known to be a car-addled and car-addicted place but not for much longer. They have consciously set out to make their city more pedestrian and bike friendly. LA as also put efforts to make their transit better. The results are clear: people love to ride bicycles rather than put up with car traffic.

Angelenos have been among the most car-dependent U.S. commuters, with 67 percent getting to their jobs driving alone in 2009, compared with 24 percent for New York and 51 percent for Chicago, according to the U.S. Census Bureau. In Detroit, home of the U.S. auto industry, the figure was 71 percent.

Villaraigosa, a 60-year-old Democrat elected in 2005, championed a 2008 ballot measure that raised sales taxes in Los Angeles County by half a percentage point for 30 years, with the projected $40 billion in proceeds earmarked for rail lines, expanded rapid bus service, widening highways and adding carpool lanes. Twenty percent of the revenue was devoted to highways, with the largest share, 35 percent, for rail and bus rapid-transit lines.

Copenhagen Gets Bike Superhighway

Copenhagen is known as the most bicycle friendly city on the planet and they keep getting better. Recently, the capital of Denmark has created a bicycle superhighway that is separated from car-dominated roads. The network of highways is designed to get people in the suburbs to get out of their pollution producers and commute more sustainably.

Other cities like London have committed resources to encourage suburbanites to commute via bicycle. Hopefully this inexpensive pro-cycling attitude will one day get to the traffic-clogged car-centric cities of North America.

The cycle superhighway, which opened in April, is the first of 26 routes scheduled to be built to encourage more people to commute to and from Copenhagen by bicycle. More bike path than the Interstate its name suggests, it is the brainchild of city planners who were looking for ways to increase bicycle use in a place where half of the residents already bike to work or to school every day.

“We are very good, but we want to be better,” said Brian Hansen, the head of Copenhagen’s traffic planning section.

He and his team saw potential in suburban commuters, most of whom use cars or public transportation to reach the city. “A typical cyclist uses the bicycle within five kilometers,” or about three miles, said Mr. Hansen, whose office keeps a coat rack of ponchos that bicycling employees can borrow in case of rain. “We thought: How do we get people to take longer bicycle rides?”

They decided to make cycle paths look more like automobile freeways. While there is a good existing network of bicycle pathways around Copenhagen, standards across municipalities can be inconsistent, with some stretches having inadequate pavement, lighting or winter maintenance, as well as unsafe intersections and gaps.

“It doesn’t work if you have a good route, then a section in the middle is covered in snow,” said Lise Borgstrom Henriksen, spokeswoman for the cycle superhighway secretariat. “People won’t ride to work then.”

Riding the Green Wave in San Francisco

For the past two years, Valencia Street in San Francisco has been experimenting with a system called “The Green Wave.” By programming the timing of traffic signals, the city of San Francisco has made it possible to ride a bicycle at a steady 13 mph (~21 km/hr) without hitting a single red light. This effectively eliminates the tiresome stopping and starting for cyclists, thus making biking even more efficient! It was recently announced that the pilot project will now become a permanent feature of Valencia Street.

Although the concept of optimizing signal timing for cyclists isn’t new, the programme in San Francisco has made some improvements that make it even better than similar systems in Copenhagen, Amsterdam, and Portland.

San Francisco’s Green Wave is already unique because it is the first in the world to work two ways simultaneously, something Mayor Newsom calls “another example of our leadership in providing quality cycling improvements for this community.”

“Those who bike in San Francisco have seen their rides become safer and more efficient. Our continued commitment is to further the progress made and further establish San Francisco as a champion for providing multiple modes of transportation,” said Newsom.

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

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.
