19. Conclusions: air travel Evidence of demand plateau (USA) and peak (Japan) – perhaps initial indications of market maturity Time constraints likely to operate but not understood – researchable Infrequent Flyers – a reservoir of demand? Main growth of Low Cost Carriers now historic Future demand – more uncertainty than generally supposed 19

20. Conclusions: daily travel Evidence from NTS –No time savings in long run –No increase in travel per capita since mid-1990s Theoretical framework of conventional appraisal and forecasting inconsistent with NTS and Peak Car evidence Investment strategies questionable –Too little urban rail –Too much inter-urban road civil engineering –Too little digital technologies 20
