Correlation between Mobility and Gross Domestic Product at Regional Level: Case Study of Primorje-Gorski Kotar County, Croatia

Abstract

The knowledge about the volume and structure of the transport demand and the possibility of good forecasting represents one of the basic assumptions for successful implementation of the transport policy measures. Studying the variation of the basic macroeconomic indicators and the level of mobility is one of the steps in this direction. The paper analyses the interrelations of the movements of the basic economic indicators and the usage of passenger cars in the area of the Primorje-Gorski Kotar County (especially the city of Rijeka). The study results can be used as a signpost to traffic planners in preparing the traffic plans, as well as to the executive authorities while planning the development of their region i.e. introducing of traffic measures in local and regional environments.

Approach Draft to Evaluate the Transport System State—A Case Study Regarding the Estimation Ratio Model of Transport Supply and Demand

“…Residents' movability rates in the model sway the supply and demand for potential travels in analyzed transport modes. Although the residents' mobility is constant in time, it has recently increased due to improved living standards [31]. The model integrates residents' movability with GDP per capita.…”

“…The crucial factor in the model is the value of "stocks" in the form of GDP volume. In general, a relationship between GDP growth and population mobility is proven [31].…”
