"Transport has become one of the key restraints on Britain’s economic growth and quality of life. Successive governments have failed to provide the standard of infra- structure necessary to keep up with an increasingly mobile and dynamic econo- my.

It currently costs our economy in the region of £20bn per year, a figure set to rise significantly in the coming years." (Quoted from paper)
