Road user charging and hard shoulder running were revealed as the top Government transport priorities this week, with a north-south high-speed rail link also back on the political agenda.
Published in 2006, the Treasury commissioned Stern report proposed spending up to 1% of national GDP to mitigate the effects of climate change. The Eddington report proposed targeted spending to ease congestion bottlenecks.
The DfT response, Towards a Sustainable Transport System, confirms £20bn will be spent on transport improvements between 2014 and 2019, as outlined in last month's Comprehensive Spending Review.
"Towards a Sustainable Transport System" is now open to consultation before a Transport Green Paper is published next spring.
