An integrated approach and unifying perspective to the networks is therefore proposed: integrated because it has to cover the whole life cycle (from conception through to construction and operation to eventual demolition and replacement), from components to system and from research to optimal use.

Five main lines of activity for future research are identified at the moment: management of the assets (incl. life cycle management), impact on the environment, safety and security, answer to increasing demand (i.e. mobility), inter-modality and inter-operability.

It is hoped to assure the economic but sustainable development of Europe by: guaranteeing functional, innovative networks of infrastructures and utilities combined with integrated services.
