The Confederation of British Industry’s (CBI) survey said congestion on Britain’s roads is costing the economy an estimated £7-8bn ($10-12bn) a year.

With vehicle traffic growing by 25% in the last 20 years, the cost of congestion is likely to more than double by 2025 unless more action is taken, according to the report.

The CBI said 80% of companies see roads as an integral part of their business, and 96% of companies want to see improvements in rush hour congestion.

CBI deputy director-general John Cridland said a radical overhaul is needed on how we travel and manage our road system.

The business group has suggested measures such as introducing shared occupancy motorway lanes, trialling more yellow-bus schemes to cut school run congestion and greater use of private road investment to cut congestion on the roads.
