Are you picturing some kind of pod-like vehicle about one square foot big?
- CamperBob2 11y agoAre you picturing a train that actually goes where people need to end up? A busy road can move more people in an hour than a train can move in a day.
- timthelion 11y agoThe two metro(subway) stations at Vaclav square in Prague have between 1 and 2 thousand people arriving AND leaving every 10 minutes at rush hour, how are you going to get that kind of capacity using cars, without having some kind if dedicated tunnel(which would be the same as a subway, just less efficient).
- CamperBob2 11y agoThat's basically the capacity of a single lane of traffic per hour (http://onlinepubs.trb.org/onlinepubs/nchrp/nchrp_rpt_599.pdf http://onlinepubs.trb.org/onlinepubs/nchrp/nchrp_rpt_599.pdf p. 13), generously assuming all single-occupancy vehicles. So we can build train stations that are guaranteed not to be where people need to end up, or we can use existing roads more intelligently. To me, that doesn't sound like such a tough choice.
- timthelion 11y agoYes, but that's per HOUR not per 10 minutes. And you cannot multiply by 6 and put in 6 lanes, because Vaclav square is only 3 lanes wide and is a PEDESTRIAN area. Also, 6 lanes wouldn't work at that capacity, because people would have to cross those lanes. Also, that capacity is for driving through, not stopping and getting on/off.
- CamperBob2 11y agoSorry, I don't agree that there's a material difference. You're comparing one highway to the single busiest train station in the city, and that just doesn't make sense. Trains are not going to be the answer. Nobody is going to be taking the train 50 years from now, or any other form of fixed-rail urban transit.
