Abstract

The port entry system of the inner harbor in PyeongtaekㆍDangjin was planned as lock-gate in ‘Master plan project on port planning in Asan industry base(1990)’, but was changed to tidal harbor in ‘Project maintaining Master plan for comprehensive development of PyeongtaekㆍDangjin port(2001)’. Accordingly, southern sea bank constructed under the lower part of Seohae-bridge will be removed so that inbound/outbound vessels for the inner harbor can navigate at all times. However, in the view of the safety on passing through the lower of Seohae-bridge, navigating conditions for the inner harbor will be restricted in the single-way of 50,000 DWT vessel and the two-way of vessel less than 30,000 DWT. Therefore, this study carried out the estimation of traffic congestion arising from these vessels with above restrictions ofter supposing annual inbound/outbound vessel’s numbers for loading and unloading cargo surveyed on the inner harbor.
