Arup, the global consulting firm, has an interesting publication out called Cities Alive: Towards a walking world. The report highlights 50 benefits of walking and then 40 actions that city leaders can take today to transform their cities. The entire study was informed by examining 80 international case studies.
As I was going through the report, the following diagram caught my attention. It compares journeys on foot vs. journeys by car for a collection of global cities.
The turquoise circles represent % of journeys by walking. On the left is Los Angeles at 4%. And on the right is Istanbul at 48%.
The red circles represent % of journeys by car. On the left is Miami at 79% (with Los Angeles right beside it). And on the right is Kolkata at 2%.
The map in the middle of the circles represents pedestrians killed in traffic crashes per 100,000 people.
I’m not sure where the data was drawn from, but it’s not all that surprising to see a few North American cities clustered towards the left (less walking; more driving). Still, I wonder how “journey” is defined.

I love the work that LSE Cities (London School of Economics) is doing with Urban Age. If you haven’t yet checked out their site, you should do that now. If you’re a city geek, it’s the kind of site you can get lost in for hours. Especially if you’re a sucker for great diagrams like I am.
Here’s one I found today that shows where cities are growing in the world:
Each circle represents a city (well, metropolitan area). The dark green dot is the city’s population in 1950. The lighter green dot is the city’s population in 1990. And the yellow dot is the city’s projected population by 2025. Click here for a larger version of the map.
What’s fascinating about this diagram is that you can so clearly see how the most significant population growth has shifted away from the West to the rest of the world and in particular Asia. That is, those dots have more yellow than green.
We, of course, already knew this was happening. And population is just one dimension. But it’s still interesting to see this in diagram form. We are living through the rise of the East. And this diagram is a reminder of that.
