[PR03] Investments in transport Infrastructure
Driving forces

Key message
Bad

In the first decade of this century, Slovenia directed most of its investments into the road network, primarily the construction of the motorway cross. The railways, on the other hand, were largely neglected in terms of investment, making them uncompetitive compared to road transport.

Since 2011, this trend has begun to change, although the overall volume of investment in transport infrastructure has declined since 2008. Since 2010, the state has allocated a significantly larger share of funds to the modernisation and upgrading of the railway network; however, this share remains, on average, smaller than that of road infrastructure investments.

The unambitious role assigned to railways in the future national transport system, along with planned investments in the expansion of motorway sections and the construction of the Third Development Axis (a major new road corridor), will likely once again relegate the railways to a much more subordinate investment position.

This indicator shows the volume of investments in infrastructure of road, rail, air and maritime transport in the Republic of Slovenia in the period 1992–2014; this includes all investments in infrastructure except regular maintenance costs. Infrastructure investments include expenses for new construction or the expansion of existing infrastructure, including restoration, modernisation and larger repair work. Infrastructure includes land, the construction of permanent transportation infrastructure, such as roads, railways, buildings, bridges and tunnels as well as fixed installations, equipment and installations in connection with them (signalisation, telecommunications, catenaries, power plants, etc.). Infrastructure maintenance costs are costs for the maintenance of infrastructure in such a condition that it may operate (SORS, 2004). Infrastructure of air and maritime transport also includes investments in equipment for traffic management and the provision of safety.

The development of infrastructure is important, as it strengthens the integration of markets, improves trade and fosters development and regional cohesion within Europe. Nevertheless, transport infrastructure negatively affects the environment in direct and indirect ways.

The indirect effects of transport infrastructure relate to their impact on biodiversity and fragmentation of ecosystems, as well as to the impact of nearby infrastructure on protected areas of nature. In Europe, the greatest threat is represented by the impact of new infrastructure on ecosystem fragmentation.

The direct effects of infrastructure relate to noise, energy consumption and emissions of greenhouse gases and other pollutants resulting from transport.
