In the past and today, Istanbul has always been
one of the most important cities in the world because
of its historical, cultural and natural features. This
fact has caused increase in population and great
transportation problem since 1950s. To surmount the
transportation problem, two bridges were built and a
third one is being constructed on the Bosphorus.
Although zone plans, which made in the 1960s,
suggested the urban growth to east-west direction,
each bridge created its own traffic and triggered
urbanization to northward.
Main objectives of this paper are to determine
the land use changes driven by Bosphorus bridges,
predict potential impacts of the 3rd bridge and
compare the effects of different routes on
urbanization in Istanbul. Two motorways were
selected among for alternative routes preparing for
3rd bridge. To find out the impacts of Bosphorus
bridges on the urbanization, cellular automata (CA)
based urban growth simulation models were created
for the year 2030 and change detection analysis were
implemented between 2009 and 2030. According to
the results, Istanbul will continue grow northward
and almost the half of forest area will be damaged
and transformed to urban area in 2030. |
