In this research, the operation analysis for straddle carrier's system of a seaport container terminal is investigated. In the present paper, the movements of straddle carrier and truck trailer at the transfer-point are recorded by video camera. The locus of straddle carrier in the stacking yard is also recorded with use of the GPS recorder. After examining an optimum way of yard operation for Straddle Carriers System from these measurement results, it become clear that making a balance with the throughput of Truck Gate and timely dispatching job order instructions to Straddle Carriers are important to shorten the length of Track Trailer's stay at the transfer point.
