The Sea-Side Port Capacity: A Synthetic Evaluation Method

This paper explains the main results of an ongoing research project concerning the development of a model capable of simulating the operation of the sea-side port terminals, to evaluate their capacity and to relate the terminal utilization degree with the quality of the transport services. The proposed model is capable of taking into account both passenger traffic and freight traffic and their peculiarities: dimensions, handiness and cinematic characteristics of the ships, effects of the wave motion on the approaching and stop times, positions of terminal and courses, etc. The methodology has been developed according to the following phases: (1) delimitation of the terminal influence area for the ship movements; (2) schematization of the port lay-out and definition of entering and exiting routes, running times, reciprocal relationships of compatibility and incompatibility; and (3) calculation of port terminal capacity. Pilot application of the model were developed for two Italian ports (Civitavecchia and Salerno).
