Traffic congestion in the UK will rise by 37% over the next 15 years if the government’s current policies continue, according to a new report by the Road Users’ Alliance.

It has called for more spending on UK roads, in an effort to make road travel more efficient in the country.

The RUA estimates that 656 million hours a year could be wasted in traffic jams if minimum levels of road investment persist.

The UK’s investment in new motorway capacity is among the lowest in Europe, with no new motorway miles created in 2007-2008, despite road users paying some of the highest road taxes in the western world.

UK motorists pay £47bn ($72.5bn) in road user taxes but the government only invests £4bn ($6bn) in new road capacity.
