Transport policy debates in the past years have clearly focused on the question which modes of transport ought to be promoted. The majority of the Swiss population has repeatedly chosen to clearly favour rail rather than road (1988 Rail 2000, 1992 NRLA, 1994 Alpine Initiative and constitutional article for a kilometre-based HGV charge, 1998/99 Act on the HGV charge and financing of public transport projects, 2004 Avanti Initiative). Despite these votes, unconditional road building is still top of the agenda. The Swiss Confederation and cantons are sanctioning and continuing with the undesirable developments of the last decade in the form of new road building projects. New roads, however, only bring temporary relief. In the long run they attract more traffic, since new roads mean better provision, which increases demand. Within a few years, new sections of road lead to a 15-20% increase in traffic.
Different studies show that good transport links are not of decisive importance for economic growth.
For example, the A7 motorway across the Thurgau region has not had any significant economic effect on those municipalities that have benefitted most from the improved accessibility.
