Report contracted by the European Commission -- DG TREN. The organisation of local and regional public transport in Europe was been submitted to considerable changes during the last two decades. Several kinds of legal features can govern the relationship between transport authorities and transport operators. Licences, authorisations, concessions, contracts, etc. are examples of such relationships. The legal frameworks of the various member states are determinant in the shaping of such relationships. This report provides a number of tools to facilitate the comparison of various organisational forms. This will help understanding the complexity of contracting practices in European public transport. Such comparison may then be the source of mutual learning and improvement. This report also provides general guidance and advice as to the development and awarding of contracts to operators of public transport services. This study is based upon a European-wide collection of representative contractual practices.
