Its also only a partial story as “damage done” doesn’t directly relate to actual costs.
Take Ottawa as an example
Transitway is nothing but buses all day long, and that has an amortized annual cost of $42,100 per lane/km/year.
A local road that sees a couple hundred car trips a day costs $14,122 per lane/km/yr.
So that’s 3× the capital cost for way way way more vehicles at 1-3,000x the “damage” per vehicle.
Bicycle lanes an amortized captial cost of around $5-1000 per lane/km/year (this number is REALLY hard to peg down due to all the different ways cities account for bike infrastructure and the type of infrastructure it is).
So a bike lane is somewhere between 14 to 3000x less expensive than a local road, despite 160,000x less “damage”
All while the bus damages the road as bad as a few thousand cars.
