Correspodence of the Structure of Road Freight Vehicle Superstructures to Transport Demand

Transportna potražnja u cestovnom teretnom prometu je ukupnost zahtjeva za uslugama prijevoza ili prijenosa roba. Roba je pri tome glavni element tehnologije prometa i bez nje ne bi došlo do pojave prometnih tokova i razvoja same tehnologije. Zadovoljavanje transportne potražnje se vrši pomoću teretnih vozila specijaliziranih za različite vrste roba. U radu se utvrđuje trenutno stanje transportnog supstrata i obavlja matematičko statistička analiza dinamike prevezenog transportnog supstrata u hrvatskom cestovnom teretnom prometu u periodu od 2009. – 2015. godine kategoriziranog prema klasifikaciji NST-a 2007 te prema klasifikaciji UNECE-a. Također se utvrđuje trenutno stanje strukture nadgradnje cestovnog teretnog voznog parka i obavlja matematičko statistička analiza dinamike strukture nadgradnje cestovnih teretnih vozila. Analizirana je međuovisnost između dinamike transportne potražnje i dostupnih kapaciteta za vremensko razdoblje od 2008.-2015. godine. Svrha analize je ustanoviti usklađenost između dinamike strukture nadgradnje cestovnog teretnog voznog parka i dinamike transportne potražnje.Transport demand in road freight is the totality of demand for transport or transfer services. Transport substrate is the main element of transport technology and without it the occurrence of traffic flows and the development of technology itself will not be possible. Satisfaction of transport demand is achieved by means of a freight vehicle specialized for different types of goods. The paper states the current state of the transport substrate and performs a mathematical statistical analysis of the dynamics of the transported substrate in the Croatian road freight traffic in the period from 2009 to 2015, categorized according to the classification of NST 2007 and UNECE classification. It also establishes the current state of road freight vehicles by type of superstructure and performs a mathematical statistical analysis of the dynamics of road freight vehicles by type of superstructure. The interdependence between dynamics of transport demand and the available capacities for the period 2008-2015 has been analyzed. The purpose of the analysis is to establish the correlation between the dynamics of the structure of the road freight transport fleet and the dynamics of transport demand
