What's more expensive? A car or a bicycle? Obvious? So how much more expensive are cars compared to bicycles?

In a comparative study, Stefan Gössling from Lund University and Andy S. Choi from the University of Queensland have investigated a cost-benefit analysis that the Copenhagen Municipality uses to determine whether new cycling infrastructure should be built.

If the costs to society and the costs to private individuals are added together, the impact of the car is EUR 0.50 per kilometre and the impact of the bicycle is EUR 0.08 per kilometre.

If we only look at costs/benefits for society, one kilometre by car costs EUR 0.15, whereas society earns EUR 0.16 on every kilometre cycled.
