"The Future of Transport" White Paper, published on 20 July 2004,outlines a long-term strategy for a modern, efficient and sustainable transport system backed up by sustained high levels of investment over the next 15 years. It looks at the factors that will shape travel and transport over the next thirty years and sets out the government response to the increasing demand for travel, maximising the benefits of transport while minimising the negative impact on people and the environment. The White Paper extends to Wales and Scotland in so far as it covers UK policy responsibilities for regulation of aviation and shipping, some aspects of road traffic regulation such as vehicle licensing, rail services in Wales and cross- border rail services in Scotland. It also covers marine, air and rail safety. It does not cover roads in Wales and Scotland, transport funding programmes administered by the devolved administrations, or transport services which operate solely within Wales or Scotland. Its proposals do not extend to Northern Ireland.
