Maglev. Similarly, some public transport investments can be poorly targeted,
sometimes as 'prestige' projects. The Maglev (Magnetic Levitation) airport
connection in Shanghai was built in 2004 at a cost of US$1.2 billion for just 33
km of line. It runs at around a fifth full, requires large operating subsidies in spite
of a high fare (US$6 one way), and has virtually no practical use for daily travel
in Shanghai (Pucher et al., 2007). Transport investment needs to be much more
carefully planned, with a consideration of the effectiveness of spending across
modes relative to likely societal impact.
