In an increasingly globalised world, the accessibility of a location essentially determines the extent to which the region in question can participate in the economic growth process. Accessibility is therefore a relevant topic in the discussion about location factors.
Accessibility is a concept that is used in various fields such as infrastructure and urban planning, but also marketing. The term has many meanings today. In general, it can be understood as the number of opportunities for economic or social life that are accessible at a reasonable cost that is appropriate to the purpose. Accessibility thus refers to the quality of a spatial point, which results from its transport connections to attractive other spatial points. It follows that accessibility is the actual main product of transport systems.
Access to procurement and sales markets plays a central role for internationally active companies and institutions. The rapid overcoming of distances helps to take advantage of market opportunities. Potential markets, both in terms of potential demand and the inputs offered there, are all the more interesting the more economically significant and the more accessible they are. A few years ago, BA Economics, together with the Institute for Transport Planning and Systems of the ETH Zurich and the Centre for Economics of the University of Basel, took up this topic by means of quantitative analysis (BAK 2003) and compares regions with each other in terms of accessibility in the sense of the benchmarking idea.
