Application of Polynomial Trend in Function of Determining Trend Growth of Container Traffic in the Port of Koper

The subject of this paper is the movement of container traffic in the port of Koper and consequently, the comparison was made with the container traffic in the port of Rijeka and Trieste in regard with the port of Koper. Container transport has a direct impact on the general prosperity of the area of Koper and Slovenia as a whole. It is, therefore, important to identify the factors influencing the container traffic in the Koper port and calculate the polynomial trend that approximates the movement of container traffic in the port of Koper, assuming that the container traffic will be moving the same way as in the previous period. From the proposed model with the processed data over the past twelve years via polynomial trend it is possible to predict the behaviour of container traffic in the next five years.
