I agree to the figures given by Lloyd Wright for for bus and rail systems.
 Whlie Dedicated bus may cost half of the dedicated elevated rail system
for the capacity of 15000-30000 pphpd.Bus system is cost effective except
for the air pollution.Of course one would be looking for capacity of
60000-80000 pphpd in the mega cities with population of 8-10 million or
more will need high capacity transit.
