First paragraph: Transport plays a vital role in every day life. The efficient movement of people and goods is an essential part of a productive economy as well as being important for social cohesion, health and well-being. Investment or policy intervention in the transport system is, therefore, in support of these other wider objectives or to tackle externalities such as climate change or congestion.
The institutional structures underpinning transport have, however, developed around modes and networks and around the industries of transport. The arrangements vary significantly between modes and, increasingly, across areas. There is a multitude of governance networks rather than a single overarching ‘governance of the transport system’. This makes it difficult to achieve integrated outcomes.
