ABSTRACT
Indicators of accessibility have a wide range of applications in empirical research in transport economics and economic geography. As an example, comparing benchmark and counterfactual accessibility indicators is common practice in the evaluation of transport infrastructure investments. Accessibility indicators have also been widely used in regression analyses trying to figure out determinants of industrial location and regional growth. A further field of application is in the prediction of spatial effects of economic integration. The basic idea is that integration reduces economic distance and therefore favours regions gaining a comparatively large increase of input and output market accessibilities (Clark et al. 1969).
