TransNet aims to promote dialogue and to co-ordinate and exchange information, know-how and experiences as a basis for mutual learning with other public and private, national and international actors in transport infrastructure. The network draws on the experience of its members and provides opportunities for constructive interaction between transport infrastructure professionals in the Swiss development and research communities, in Swiss municipalities, and in private consultancy, as well as others interested in the problems and issues of transport infrastructure in developing countries.

Since 1999 TransNet has regularly held meetings, and the increasing number of participants and interested organisations indicates its growing success. The meetings allow a useful exchange of experiences and information among its members and provide a high-level forum for discussing important issues in transportation, including technical and institutional aspects, particularly public-private partnerships, poverty & transport, good governance and community involvement. The members' list currently includes 31 individuals from 17 different organisations and companies.

One substantial output of TransNet is the TransWeb, an Internet portal to the transport sector providing selected links to up-to-date information on various aspects of transport.
