| Abstract |
|
A construction project, of Incheon 2nd bridge, which is connected between the Incheon Song-Do New Town and the Incheon International Airport in Young-Jong-Do, has been proposed by the private capital in 1999. But the optimal width of the main span has not been decided in spite of the three investigations into the feasibility of ship’s safe transit in this planned bridge. In this paper, we study the economic analysis on port operational efficiency according to traffic schemes, one-way or two way of vessels over 10,000G/T, in the main span of this bridge.
In this comparative result, total queueing time due to the one-way in the bridge main span, is evaluated 20,362 hours in 2011 and 24,544 hours in 2020. Therefore, the demurrage cost and the accumulation cost of freight are evaluated 19.7 billion won in 2011, and 23.3 billion won in 2020, then total accumulated costs during 33 years from 2008 until 2040 are evaluated about 768.9 billion won. |
