Frogs and Lizards Rank Higher Than Humans


Enrique Penalosa, former Mayor of Bogota, spoke at the International Transport Forum in Leipzig today and he brought an interesting observation to the discussion.

Millions of dollars are spent protecting frogs and lizards but pedestrians and cyclists often suffer from lack of infrastructure.

It's a great comment. Ranking frogs higher than humans in our spending.

What he is referring to is the many wildlife crossings that are built to protect wildlife and prevent wildlife/car conflicts. The most well-known examples are in Canada, providing safe passage for wildlife that wish to migrate across the Trans-Canada Highway:


What an impressive, expensive structure. I'm pleased that the wildlife doesn't have to suffer the destructive capability of the automobile. Hell, they don't even have to suffer SEEING the cars because of the foliage.

30,000 cars a day pass this point in Banff National Park in the summer. Which, however, is a number similar to the number of cars on many city streets. Here is a link to several other photos of these overpasses.

Here's a text from Parks Canada's website about the crossings:
This overpass was built JUST for wildlife (no humans allowed!). It’s on the Trans-Canada Highway in Banff National Park, which serves more than 30,000 vehicles a day in summer. As you can imagine, fencing this wide and very busy roadway has greatly reduced roadkills. But without crossing structures, park wildlife would be unable to move from one side of the valley to the other. And wild animals need to move freely throughout their habitat to stay healthy.

It's quite easy to see Penalosa's point. Great sums of money spent to protect animals but very little money spent to protect humans on bicycles or foot in our cities.

Look at the last sentence in the text from Parks Canada. Human beings are no different. They need to move freely throughout their habitat to stay healthy, too. If someone could tell me how much these overpasses cost, I'll tell how many km of cycle tracks could be built for the same money.


On the same website you can see an example of wildlife underpasses. The one above, from Wateron Lakes National Park, is designed specifically for long-toed salamanders. There are also 27 underpasses along the Trans-Canada Highway through Banff National Park, in addition to the overpasses.

In Davis, California, cute houses are built to hide tunnels that help frogs cross the street.

The company Theiss is proud of their highway fauna crossings in Australia, as you can see on their website. Although you can also read that "187,000 seedlings were planted, eventually equating to taking 1265 cars off the road.". Ignoring the Bull and Greenwashing all at once. Plant trees, sure, but please don't pretend it reduces car traffic. Seedlings, as far as I'm aware, don't kill people in collisions.

Wildlife crossings were first built in the 1950's, in France. The 1950's really are a pivotal decade in urban mobility and not at all in a positive sense. The post-war prosperity that led to the explosive automobile boom in that decade. It was in the 50's that bicycle usage started to drop in cities all around the world as urban planners started to think car first and pedestrians/cyclists second. The cycle tracks in Copenhagen started to be removed in the 1950's to make space for cars and only reappeared in the 1980's.

This Wikipedia page has lots of information about wildlife crossings or ecoducts. They are found in many countries. Densely populated Netherlands is one nation that has many wildlife crossing solutions. But they invest, of course, in protecting their human cyclists first.

So that's what Penalosa was on about. And rightly so. Protect the wildlife with large amounts of taxpayers money. Absolutely. But don't do it without providing homo sapians in our cities with safe bicycle infrastructure and safe pedestrian facilities.

Safe urban mobility is a basic human right that deserves investment and vision.

7550 New Bike Parking Spots at Copenhagen Central Station

For all of Copenhagen's badassness as a bicycle city, there remains one thing that the City still completely sucks at. Bicycle parking at train stations. At Copenhagen Central Station there are only about 1000 bike parking spots. Danish State Railways can't even tell us how many spots they have. They're not sure. Even in Basel they have 800+. In Antwerp they have this . Don't even get me started on the Dutch. 12,500 bike parking spots are on the way in some place called Utrecht . Amsterdam has a multi-story bike parking facility, floating bicycle barges round the back and are planning 7000 more spots underwater . Even at the nation's busiest train station, Nørreport, the recent and fancy redesign failed miserably in providing parking that is adequate for the demand . Architects once again failing to respond to actual urban needs. It is time to remedy that. Here is my design for 7550 bike parking spots behind Copenhagen Central Station. Steve C. Montebello i...

The Race for Lithium for Electric Cars and Bicycles

Uyuni Salt Flats, Bolivia. Photo: Ezequiel Cabrera/Wikipedia The coming boom in batteries to electric cars and Lazy Bikes (electric-assist bicycles) means a boom in batteries with which to run them. A new race for natural resources has begun. Enter Lithium, the world's lightest metal. For 150 years it's been nickel and lead that have been used in batteries but the advent of lithium technology has allowed for a revolution. Longer battery life, lighter batteries in our laptaps and mobile phones and iPods. Lithium weighs 1/20th of what nickel and lead do. Lithium is also used in anti-depressive medicine, ceramics and nuclear power. With all this talk of electric cars and bicycles, the demand for lithium is on the verge of exploding. Lithium is the new oil. Enter Boliva. This developing country sits on at least half of the world's supply of lithium, most of it in underground salt layers beneath the world's largest salt flats in Salar de Uyuni , in south-west Boliva. Betwee...

Traffic Safety Orgs Speak for Themselves - Not the Rest of Us

Classic traffic safety organisation narrative. "Stop cycling". By Stephanie Patterson With Mikael Colville-Andersen In the diverse world of traffic planning, advocacy and various movements for liveable cities, there is an odd group of outliers who broadcast conflicting messages. While “traffic safety” organisations seem like a natural part of the gallery and of the narrative, upon closer inspection they exist in a communication vacuum populated exclusively by like-minded organisations. There is little correlation with those organisations who advocate cycling, pedestrianism or safer streets. The traffic safety crowd are in a world unto themselves, with little or no accountability for the campaigns they develop or the messaging they broadcast. They are often allied with insurance companies who clearly take comfort in working with others who embrace scaring the population at large through constructed fear . In many ways, they are a classic subculture, with strong hints...
