RE: WorldTransport Forum capacities for different modes of transport
Please note flat earthlings, that the most used form of mechanized transport in the City is the vertical lift. Ask yourself how many times did you go up and down in a lift today? Ten brownie points if you chose to walk up or down some stairs instead.
The ‘dense’ city has a vertical transport ‘cost’ which is oft forgotten that offsets the horizontal benefits flat earthlings are obsessed about.
When considering the capacity of a certain area of land for different modes of
transport, there are a couple of factors that have to be equalised between modes
(car on street, car on highway, conventional bus, BRT, light rail, heavy rail
1. Is it required that people should be able to get on and off the system at
almost any point ? (Roughly speaking, yes for conventional bus, light rail and
bike; this objective is sought by traffic planners for cars on streets but often
2. Do people need to cross the route, especially on foot ? (Roughly speaking,
no for car on highway or heavy rail, though especially in the former case people
often do need to cross the route but are unable to do so. For the other modes
adequate provision for crossing pedestrians may reduce capacity, especially for
car on street and bike. Do places exist where buses are so frequent that
crossing the street is a problem ?
