    Taking buses and trucks off the road saves a disproportionate amount of road maintenance costs go up in proportion to the square of the weight.

    And of course, steel rail is far more durable than asphalt.

    So including the cost of path construction but leaving out the cost of path maintenance is putting a heavy thumb on one side of the scales.

    That's why the primary target for quality trolley buses is for corridors that will not be able to provide the patronage to bring them into the light rail frame ... the total cost per service, including periodic maintenance, is higher for BRT than for LRT, so as the frequency of service goes up, the the fixed cost / operating cost comparison will always swing from BRT to LRT.

    Its also another reason why local circulator buses that include a rail station are effective, since they "pay for" more frequent buses on a portion of the trip by taking a large share of the longer trips off the roads entirely.

    Add in the fact that federal matching funds are biased toward up front capital costs and against operating and periodic maintenance costs, and a community that opts for a BRT on a corridor that is capable of supporting LRT is building up it roadworks expenses for the future.

      I asked the question because every time I find real numbers and apply them, I find light rail is more expensive.  You just parroted more of the same without a single number or single citation.

      No on Prop 8::Sometimes I get to hitch a ride on the Democratic Bus--they let me stand on the back bumper.

        Estimating Heavy Vehicle Road Wear Costs for Bituminous-Surfaced Arterial Roads

        Journal of Transportation Engineering, Vol. 128, No. 2, March/April 2002, pp. 103-110.

        However, no citation is required to note that if that is the way you "compare" transport costs, you are always going to get results that are biased against a more durable pathway with lower vehicle wear costs per ton-mile and a less durable pathway with higher vehicle wear costs per ton-mile.
