European integration has seen dramatic changes in mobility patterns to meet developments in economic activities. However, decision-makers lack information on current patterns of transport activity, and there is only limited knowledge of the impacts of existing policies and investments. Therefore, the European Commission has been promoting the development of a European Transport policy Information System (ETIS). ETIS is intended to provide a central means of access to transport statistics. It could also include a wider range of decentralised information, allowing lessons from past infrastructure projects to be remembered and made available to wider audiences.
