The document summarizes a toolkit created by the World Bank to help developing countries implement public-private partnerships (PPPs) for road and highway projects. The toolkit contains six modules that cover key aspects of PPPs like policy, planning, laws/contracts, and financial models. It aims to fill gaps in knowledge about developing PPPs and presents case studies and best practices to understand where and how PPPs can be appropriate. The financial models included help understand the basics of project finance and how different assumptions impact a project's viability without requiring specialized financial expertise.
