The RAC Foundation has warned in a new report that the motorists in the UK are expected to see longer delays on the roads in the UK as the number of cars is increasing and the government has decreased the spending on transport infrastructure.

The report says that about four million cars will be added to the UK’s roads in the next 25 years as the population will increase by more than 10 million in the next decade. The volume of traffic will increase by 43% by 2035 and the delays over the next 25 years will rise by 54%, it said.

RAC Foundation said that in the face of this scenario "the Government has significantly reduced road transport investment because of the recession and ministers have not explained what plans they have to cope with the bleak picture painted by their own numbers".

RAC pointed that, in association with its consultancy group Arup, it has identified 96 unfunded road schemes that are still waiting for approval from the Department for Transport of the British Government. The schemes were expected to deliver good returns as top 10 projects all offering benefits of more than £6 for every pound.

RAC Foundation director Professor Stephen Glaister criticized the ministers for not having any plans to deal with the projected growth in traffic in the coming years. He added that it is a situation with ‘jams today, and even more jams tomorrow’.
