Urban sprawl is often one characteristic of fast
growing cities in Asian developing countries. With a lack
of effective planning and land use control, the urban
sprawl in these cities has grown continuously and uncontrollably
for a long period. For instance, a previous study18
discovered that evidently, the urban sprawl of Bangkok
has grown more rapidly and continuously than Tokyo
during the period of 1965-1985, which is a result of low
population density spreading over the entire city. As a
result, the corridor with high demand for supporting BRT
development is much more difficult to be identified.
