- Road damage increases dramatically with axle weight. This means that
- a typical bus, weighing ~10 times the weight of a typical car, will
- cause MUCH more than 10 times the damage of 1 car.
-
- If you want anecdotal evidence of this, take a look at the road surface
- at a bus stop that has not been reinforced. Alternatively, look at the
- surface of a road that has a long standing bus lane. The results are
- dramatic!
