2. Transportation in Istanbul

Before designing the vessel, a comprehensive research was made for understanding current
situation of transportation in Istanbul. The demographic structure, frequently used lines and
passengers carried were examined; mass transportation alternatives of the Bosporus were
inspected. Transportation in Istanbul is conducted by ġehir Hatları A.ġ. of Municipality of
Ġstanbul, recently privatized Ġstanbul Deniz Otobüsleri A.ġ. and private companies such as
Turyol and Dentur. Local government body and private companies have a total of 481 sea
transportation vessels. Sea transportation lines in Ġstanbul are mainly operated between Asia and
Europe as well as Princes' Islands. In Table 1 the number of daily passengers in Istanbul sea
transportation is given.
