China has built an elevated bus that travels above car traffic
Can anyone provide some analysis / urban planning snobbishness? What are the disadvantages? Off hand it looks scary to drive under / around. Unlike a bus, one accident can cause the entire line to get backed up. You could say the same thing about subways, but subways can't get into car accidents in the first place.<p>Furthermore it can only run in places that have wide four lane roads (2 in each direction) to begin with. There's not that many appealing residential places next to loud, busy roads. Is it possible to build practical commuter routes serviced by this type of vehicle?<p>Of course I'm not a total cynic. If the problems could be hammered out then it will be quick like a subway (no traffic) but much less expensive. I'm curious to see how this experiment pans out.
