“…New additions generally do not lead to major shifts in accessibility, either in major travel time savings or transport cost reductions (Vickerman et al, 1999;Rietveld and Nijkamp, 2000), perhaps with the exception of new types of advanced transportation infrastructure such as high-speed trains (Vickerman, 1995) or when connecting peripheral regions such as islands or enclaves. It appears that in advanced economies new transport infrastructure is not the key driver of economic growth but rather plays a supporting role, as growth is dependent on a range of other economic, investment, political and institutional conditions (Banister and Berechman, 2000;Sharp, 1980;Hart, 1993;Rietveld and Nijkamp, 2000). This would also explain the rather limited effect of changes in accessibility on shifts in employment generally found by empirical analyses (Dodgson, 1974;Nelson et al, 1994;Linneker and Spence, 1996;Bruinsma et al, 1997;Rietveld and Nijkamp, 2000;Holvad and Preston, 2005;Pugh and Fairburn, 2008).…”
