ABSTRACT

Paper presents validation of previously created stochastic ships traffic stream model by
the real data of ships delays on Świnoujście — Szczecin waterway. The model is mostly
based on Monte Carlo methodology. The model is microscopic which means that each
ship’s model is treated as separate object possessing given attributes. As the main parameter of presented validation total waiting (delay) time of ships have been applied. The time
of ships delays was possessed from Szczecin VTS centre and compared with the model
output.

KEYWORDS

ship traffic stream model, waterway capacity, ship intensity, congestion, ship intensity, ship traffic streams.
