Transit rewards

    Meanwhile, the 47 Muni bus that connects the Van Ness transit corridor to Caltrain has been “suspended” since 2020, and the extension of Caltrain to the transit center is still unfunded.

    I appreciate solutions that meet us where we are, but it’s depressing that we don’t seem to actually have the will to make a sustainable, integrated mass transit plan.

      The reason there's not more public transit is because the economics are terrible. Looking at the financials:

        Cost per passenger trip:
          BART: $1.07B operating expenses / 59.5M trips = $16.92
          SF Muni: $1.13B / 160M trips = $7.06
          Caltrain: $225M / 9.1M trips = $24.73
      
        Passenger Fare collected per trip:
          BART: $259M / 59.5M trips = $4.35
          SF Muni: $111M / 160M trips = $0.69
          Caltrain: $58.7M / 9.1M trips = $6.45
      
        Subsidy per trip:
          BART: $12.57
          SF Muni: $6.37
          Caltrain: $18.27
      
        Cost per passenger mile:
          BART: $1.07B / 892.5M passenger miles = $1.20/mile
          SF Muni: $1.13B / 312M = $3.62/mile
          Caltrain: $225M / 177.5M = $1.27/mile
      
        Subsidy per passenger mile:
          BART: $1.07B / 892.5M passenger miles = $0.84/mile
          SF Muni: $1.13B / 312M = $3.26/mile
          Caltrain: $225M / 177.5M = $0.94/mile
      
      Every single ride requires a $6 to $18 subsidy, paid for by tax dollars.

      For comparison, federal spending for the interstate highway system is about 2-3 cents per passenger mile.

        Are you factoring in fixed costs to that estimate? That may be partially misleading if so.
        1. tristanj · · focus · HN ↗
          Obviously yes, you have to since the vast majority of expenses (>70%) are fixed costs. If you only exclude them and only look at marginal costs, they're profitable.

          But you cannot run a transit system on marginal costs, so using that comparison is also misleading.

            Thought experiment: What would happen with total profitability, given positive marginal unit economics, if readership were to greatly increase?

              I’d imagine it would get really congested unless massive fixed costs were expended to make the system higher capacity.
