> If this project manages to reduce the cost per mile of building public transportation, the public as a whole will benefit greatly in the years to come. I'm not rich and I would love there to be many more subway lines built out in our cities. The purported cost savings are primarily coming from making the system as incompatible as possible with traditional subways (i.e., the proposed tunnels are too small to be refit to accept standard loading gauge tunnels). Beyond that, the entire Loop concept boils down to a really low capacity system (subways generally are capable of moving 20,000 people an hour, all you really need is the rolling stock and traction power to make that happen; this system is talking about 2,000 people an hour with no room for upgrades without boring more tunnels--on par with a single highway lane). While the cost per mile might be reduced, the capacity is so low that the actual cost of the full system would be much higher. |

2000 for a typical mixed-use highway lane. A dedicated/managed lane can move several times that number. 50-person buses at two per minute = 6000 people per hour. For sheer people moving potential, things like escalators and moving walkways actually do pretty good. They are just very slow.
