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.
