Hiking, camping, canoeing – if it’s an outdoor adventure, it should be under this heading

More cycle-friendly Burrard Street Bridge

The Burrard Street Bridge – one of Vancouver’s prettiest – has been modified so as to be more friendly to cyclists. One of the two sidewalks has become a dedicated corridor for cyclists heading north into downtown. Meanwhile, one traffic lane has been converted for use by cyclists heading south toward Kitsilano. Pedestrians will be restricted to the other sidewalk.

The move is a very welcome one. The bridge offers nice views of the mountains, False Creek, and downtown. Making it cycle-friendly also contributes to a beautiful cycling arc extending from the University of British Columbia, along the beaches to the Granville Island area, then across the Burrard Street Bridge and along the waterfront path to Stanley Park.

Cyclists in Vancouver should definitely give this ride a try, while the six month bridge trial is ongoing.

Pine beetles spreading into the US

Coiled firehose

According to the BBC, the climate-linked mountain pine beetle epidemic in British Columbia is threatening to spread south and west, into the United States. Forests with a mixture of species and small regular fires would be more resilient, overall.

In addition to mentioning the importance of warm winters in aiding the spread of the insects, the article describes how past fire suppression policies have produced huge areas of mature lodgepole pine, which are especially susceptible to the beetles.

The continuing spread represents not only an economic and environmental cost linked to climate change, but also a potentially serious positive feedback effect. It is estimated that Canada’s boreal forests alone contain about 186 billion tonnes of carbon dioxide equivalent: an amount equivalent to about 25 years of global emissions at the present level.

Grouse Mountain’s 1.5MW wind turbine

Fence and brick wall

According to the Megawatt blog and The Vancouver Sun, the Grouse Mountain ski resort is going to put a highly visible 1.5MW wind turbine near the mountain’s highest point.

While the move is more symbolic than substantive, the turbine is expected to provide about 20% of the power requirements of the resort. It will also be a tourist attraction in and of itself, with a viewing platform 58m up. The turbine is meant to go up in August or September, and produce power in early 2010, in time for the Vancouver Olympics.

The most important impact may be making people gradually more tolerant of visible renewable energy facilities. If we are going to escape our harmful dependence on fossil fuels, we are going to need a lot of them.

Bixi bikes in Ottawa

The Ottawa area now has four bicycle rental kiosks – two in Gatineau, and two on the Ottawa side. The company that provides them is called Bixi and they are priced to encourage brief usage: free for 30 minutes, $1.50 for the next thirty, $3.00 for the next thirty, and then $6.00 for each half hour after that. To take one out, you swipe your credit card. It charges the appropriate amount when returned to another station. Montreal has a system with the same bikes: 3,000 of them at 300 locations. The Montreal system apparently cost $15 million, and is expected to pay itself off with user fees.

The stations are outside the Portage Complex and near the Civilization Museum in Gatineau, as well as beside the ByWard Market on Sussex near York and on the other side of the Canal at Elgin and Queen.

I want to try doing a rally between all four, making each trip in less than half an hour, so as to make it all free. Going from Portage to the Civilization Museum would be a breeze. From there to the ByWard stop would also be pretty easy, across the Alexandra Bridge. The trip between the Ottawa stations would be short, but going from the Elgin station back to Portage would be the trickiest part to achieve in half an hour, though still very possible.

The system should be very useful for both visitors and residents. I hope people treat it with respect.

Slowing the demise of Germany’s last glacier

Apparently, the last glacier in Germany is going to be covered up during the summertime to reduce melting. Located in Bavaria, at an altitude of 2,962m, the Zugspitze glacier will have an area the size of a soccer field covered with 30 metre long tarps, in order to protect its 40 remaining metres of thickness.

Apparently, protecting glacier coverings are also being used in Switzerland and Austria.

The value of private cars in cities

In the midst of the discussion about the ethics of traveling to Vancouver, the issue of how cars have benefited and harmed people living in urban areas came up. It is undeniable that they have been a major transformative force, when it comes to the shape and character of cities.

To me, it seems that private cars in cities do more harm than good, for a slew of reasons:

  1. They kill a lot of people: both drivers and pedestrians.
  2. They take up a lot of space and alter urban design in negative ways, contributing to sprawl and vast areas of just residential or just commercial zoning.
  3. Sprawl reduces natural and agricultural space. It also leads to people commuting, which is a major waste of their time.
  4. They pollute and emit greenhouse gasses.
  5. They are loud.
  6. They cause neighbours to know one another less than they otherwise would.
  7. They help make many states dependent on oil exports, and frequently involve them militarily in Middle Eastern conflicts.
  8. They have made roads into hostile spaces for everything but automobiles, whereas previously they were more versatile public spaces.
  9. The roads they require are built with public money, though they do not provide value to everyone, and contribute to serious negative externalities.
  10. They use energy quite inefficiently, since they move faster than is sensible, and the mass of the vehicle itself far exceeds that of passengers and cargo.

If it were possible to re-design cities, I think it would be better if they excluded cars entirely within their cores and had a lot of dedicated transit and bicycle routes. Stores could be permitted to have delivery vehicles for large items, and taxis could continue to exist, but the use of private cars within city limits would ideally be eliminated.

What points would people offer to defend private cars in cities? Also, are there and indictments against them I missed?

How to be safe around cyclists

Gull (Larus), near the Ottawa River

In my own experience, the situations that endanger cyclists and the operators of other vehicles near them usually arise because of a lack of awareness about making movements perpendicular to the flow of traffic. In front of a cyclist, imagine a cylinder projected forward, with a length corresponding to the distance it would take that cyclist to stop safely. If you move into that cylinder, there is likely to be a collision.

To avoid this, I suggest two basic practices:

  1. Move in a clearly signaled and predictable manner. When making turns, always signal them. Do not make turns from lanes where it is not allowed. When opening a car door beside traffic, do so slowly. When changing lanes, signal and do it in a smooth and controlled way. When entering the flow of traffic, do so in a controlled and visible way.
  2. Check your blind spots, whenever moving more than half a lane to the left or right. In particular, make sure to check the blind spot to your right when you are making right hand turns (even if you are in the rightmost lane) and make sure to check your left blind spot when opening a car door beside traffic. Those two habits can help you avoid the two most common cyclist fatalities: the ‘door prize,’ which occurs when a car door gets opened in front of a cyclist and they collide, and the ‘right hook,’ where a vehicle makes a right turn in front of a cyclist and they collide.

None of this is to say that cyclists are not responsible for safety, as well. Indeed, all the behaviours above apply to cyclists dealing with other cyclists.

In addition to these, cyclists should be highly visible, signal clearly, obey traffic rules, and move in a clear and predictable manner. Don’t cycle within door range of parked cars and, if safety requires it, feel free to occupy a whole lane. Cars behind you might start going nuts, but it is a smarter option that cycling on some marginal pavement or in an unsafe position. For example, there are a number of roads in Ottawa where the pavement on the rightmost extreme is in a very bad state of repair – so much so that it might make you fall or force you to swerve. In these situations, I find it sensible to make sure there isn’t a car just a couple of feet to the left of me.

Going back to the safe stopping cylinder for a moment, it is true that a cyclist can stop very quickly if absolutely necessary – though the process is chaotic and unpleasant. It consists of braking so hard you lock your front wheel, then going flying over your handlebars. It is better than colliding with a car, but it is far from pleasant and can generate other unexpected movements or collisions. Helping cyclists avoid these kind of stops is one of the more important things you can do as someone sharing a road or path with them.

Bicycle physics

For those with an interest in both cycling and physics, the Wikipedia article “Bicycle and motorcycle dynamics” is well worth reading. It is interesting to note that lateral movements of bicycles (basically, those involving turning) are so mathematically complex that they require “two coupled, second-order differential equations… to capture the principle motions” and that these equations cannot produce exact solutions.

That contrasts in an interesting way with the experience of making turns at speed on a bicycle, and the appreciation one gains for the relationship between body movements, bicycle movements, and the condition of the ground.

Photos of Ontario and Quebec birds

Here is a list of the birds I have photographed so far as part of my open-ended project. The links go back to the posts in which the photos originally appeared. Eventually, I might sub-divide this list according to type or location.

Presently unidentified birds: none.

More good service from MEC

Once again, I have been reminded of why it makes sense to buy gear from MEC. On Friday, I was cycling along the Ottawa River pathway when I spotted a small beaver lodge in a little wooded area. I stopped, got out my camera (with 70-200mm lens) and approached the lodge, holding my handlebars with one hand.

I stuck around for a few minutes, trying to spot a beaver and snapping photos of birds while I waited. Eventually, I gave up and returned to the path. When I got there, I saw that the cable for my bike computer (which runs down to the sensor) got sheared off by an errant branch.

I went to MEC and, without a question or the need for a receipt, they gave my a replacement sensor, cable, and dock (they are one unit). They even offered to refill my water bottle for me.
