More Cyclists = Safer Cyclists

In a recent report from the City of Minneapolis (recently voted the best city in the US to ride), data shows that the more cyclists are on the roads, the fewer the collisions there are between cars and bikes.

For 2008, the most recent year for which complete data were available, the crash rate was one-quarter that of 10 years earlier. Moreover, a trend line shows a steady decrease in the crash rate even as the number of commuting cyclists more than doubled.

These findings are consistent with other cities too!

It squares with a 2003 analysis on biking and walking in two California cities. “A person is less likely to collide with a person walking or biking if more people walk or bicycle,” public health consultant Peter Jacobsen wrote in the journal Injury Prevention.

So if you want to feel safer on your bike, get your friends on the road too!

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.

New Speed Record for Electric Airplanes

Electric airplanes are still rare but hopefully this will change sooner rather than later. Airplane fuel is super-dangerous for our friendly environment so if we can get planes to run off of batteries (electricity of course coming from wind or the like) than score a million for the good guys!

Cri-Cri is a small aircraft that just broke the electric plane speed record with ease and could herald the development of personal aircraft being electric!

According to Electravia, the firm who designed the Cri-Cri’s 35-horsepower motors and custom propellers, the plane was only using 75% of its total power when it broke the speed record. The engineering firm said that its engines and propellers could have taken the plane to speeds over 220 mph, however such velocity would have put serious stress on the Cri-Cri’s airframe so only 75% power was used.

Good News on Airplane Accidents

Many people have a fear of flying, yet, those same people have no fear about getting into something that is far more likely to kill them: their car. The CBC has an article that points out how safe flying is despite people’s exaggerated fears.

There have been countless in-flight incidents that that could’ve ended disastrously, but were resolved without loss of life. Here’s a look at a few of them.

Jan. 15, 2009: A U.S. Airways Airbus A320 loses power to both engines shortly after taking off from New York’s La Guardia airport when it strikes a flock of geese. Capt. Chesley Sullenberger is able to guide the crippled aircraft to a safe landing on the Hudson River, where rescue boats and ferries plucked the 155 passengers and crew from lifeboats and the plane’s wings before it sank in the frigid waters. There were no serious injuries.

August 24, 2001: An Air Transat A330-200 glides to an emergency landing in the Azores after a fuel leak shut down both engines. The plane, which was on a flight from Toronto to Lisbon, glided for about 20 minutes after running out of fuel. The plane made a hard landing, damaging the landing gear, but came to a stop on the runway. None of the 291 passengers or 13 crew members were killed, although several suffered serious injuries, including fractures and shock. A Portuguese investigation cited faulty maintenance and noted the pilots failed to detect the fuel leak.

Yes, I know that flying is horrible for the atmosphere but hey, here’s some good news on how safe planes are!

Solar Energy to Power Trains

Trains are a great transit solution and are efficient at moving people and goods. Trains are really a green way to travel.

In Belgium, they are taking this green form of travelling and making it even better by powering the trains using solar power.

More than 16,000 solar panels will be installed on the roof of the high-speed rail tunnel stretching just over 2 miles long. The tunnel is primarily used by the high-speed train connecting Amsterdam and Paris via Brussels.

The roof’s total surface area is 50,000 m2, roughly equivalent to 8 football fields. The installation should generate an estimated 3.3 MWh of electricity per year.

The installation commenced this summer on the tunnel’s northern side. Project completion is scheduled for December 2010. The total investment budget is $20.1 million.

Infrabel, the Belgian railway infrastructure manager, will use the green energy in the Antwerp North-South junction (including Antwerp Central Station) and to power both conventional and high-speed trains running on the Amsterdam-Brussels-Paris line. With this project Infrabel has re-emphasized its belief in renewable energy as a viable alternative, and complement, to conventional energy sources.
