Transport infrastructure deregulation and public-private partnerships have been evolving since the 1990s. Private initiatives initially work well, but eventually, the public sector steps in due to sector shocks. The public sector then faces challenges and adopts hybrid solutions for sector survival. The effectiveness of deregulation is reviewed from efficiency, fiscal, and users' perspectives. Governments need strong commitments to sustain reforms and address issues like tariff structure, quality, and competition. The study emphasizes the need for corrections in transport systems to ensure sustainability.
