Urban environments in post-socialist cities have generated new challenges for urban planners and decision makers. As one example, the transport infrastructure of Bratislava has not been adjusted with respect to increasing mobility and the transit problems of its intra-urban environment. An upgrading of the conventional railway networks within the city is one of the major opportunities which might considerably improve public transit capacities available for both intra-urban and regional (suburban) transport flows of passengers. Relevant studies on the population potential of residents supporting such upgrades are still lacking. In addition, a detailed database on population distributions within the intra-urban environments of Slovak cities is not yet available. Therefore, this paper attempts to introduce one of the possible methodological approaches leading to an estimation of population potential as an elementary precondition of intra-urban railway traffic effectiveness, in a society where a detailed database on population distribution is not available.
Population ageing in the EU28 is an important twenty-first century phenomenon, affecting virtually every aspect of life in these countries. The results of the latest EUROPOP2018 population forecast indicate that the rate of ageing is accelerating. The aim of this paper is to analyse the current level of population ageing in the EU28, identify spatial differences, and point to likely trends by the middle of this century. For these purposes, we have used a combination of conventional chronological indicators of population ageing and a set of new indicators based on prospective age that allows for a more comprehensive and realistic view of population ageing. We use multivariate statistical methods (factor and cluster analysis) to identify groups of countries with similar population ageing characteristics, using both a retrospective and prospective approach. We decompose changes in selected ageing indicators into the separate effects of changes in the population composition (children under 15, working-age population, elderly). We then identify the effect of major demographic factors (migration, mortality, cohort turnover) for the set of EU28 countries
Dynamic economic expansion of metropolitan regions in post-communist central Europe induces dynamic traffic growth, which calls for new transport network solutions and improvements to existing transport infrastructure within the regions. This is also the case of Bratislava as the capital city of post-communist Slovakia, which has recently been facing new economic and urban development challenges. A booming labour market, intensive suburbanisation processes, traffic expansion and urban (re-)development bring new conflicts and demand for grand-scale transport projects. An ongoing upgrade of the motorway system in the region of Bratislava will result in the construction of a substantial part of an orbital motorway surrounding the southern and eastern parts of the city. The potential effects of the motorway network-upgrade projects on the city urbanism are probably immense. This paper attempts to evaluate the possible changes in accessibility within the road network after completion of motorway upgrading project D4/R7 in the metropolitan area of Bratislava. The interaction potential of both population and jobs was applied here to assess possible impacts of road network enhancement on accessibility of places of residence and of work.
