Qualitative and quantitative forecasting methods of traffic demand with application

Kvalitativne i kvantitativne metode prognoziranja prometne potražnje su metode kojima se mogu ispitivati i promatrati ponašanje određenih pojava. Kvalitativne metode su bazirane na ispitivanje pojedinaca ili grupa pomoću raznih anketa odnosno metode prikupljanja i analiziranja dobivenih podataka koje se odnose na različitim razmišljanjima ispitanika. Omogućuju razumijevanje ispitivanog problema. Kvantitativne metode oslanjaju se na brojčane podatke, odnosno vremenske nizove te njihove međuodnose. Pogodne su za analiziranje kada postoje podaci iz prošlosti te se na njihovoj bazi mogu raditi buduće prognoze i pretpostavke. Primjer kvalitativne metode, ankete, prikazuje princip provođenja i ispitivanja određenih informacija koje su potrebne. Primjerom za kvantitativnu metodu, analizu vremenskih nizova, predviđen je budući promet na kontejnerskom terminalu Brajdica.Qualitative and quantitative methods of forecasting traffic demand are methods by which the behavior of certain phenomena can be examined and observed. Qualitative methods are based on the examination of individuals or groups using various surveys or methods of collecting and analyzing the data obtained that relate to the different thoughts of the respondents. They allow an understanding of the problem being examined. Quantitative methods rely on numerical data, ie time series and their interrelationships. They are suitable for analysis when there is data from the past, and by applying the quantitative method, future forecasts and trends can be obtained. An example of a qualitative method, a survey, shows the principle of conducting and examining certain information that is needed. An example of a quantitative method, time series analysis, predicts future traffic at the Brajdica container terminal
