The 1990s saw an increase in the liberalisation of transport policies and a strengthening of the role of private operators and investors in transport infrastructure worldwide. The search for sustained improvement in efficiency is probably secondary to the need to find additional financing, but it is improvement in services that is at the core of the new role of the government in transport. Governments must now become fair economic regulators of many of the privately operated transport services and infrastructures. This book examines the major challenges that governments are likely to face in taking on their new role in transport.
