TRISP: Knowledge Products

Transport and Rural Infrastructure Learning and Sharing Programme (TRISP) was a partnership between the UK Department for International Development and the World Bank for learning and sharing of knowledge in the fields of transport and rural infrastructure services. The objectives of TRISP were to facilitate and enhance the information services that are required by decision makers for transport and rural infrastructure services to enable governments, private sector, civil society, individuals, and donors to know what the key issues are, how to implement best practice, and why certain measures are appropriate such as guidance on the policy decision process and the development of best practice guidance.

Below is a list of knowledge products prepared with TRISP funding arranged in the following Categories:
