With a valid Smart Motorway subscription the Pure keeps you informed on all controlled motorway's around England. When the variable speed limit changes on the Smart Motorway you are traveling on, the Pure will alert you to the change of speed limit in real-time! This is all thanks to the direct connection to Highways England that Road Angel utilises.
The future of motorway traffic management! A smart motorway is a section of a motorway that uses traffic management methods to increase capacity and reduce congestion in particularly busy areas. These methods include using the hard shoulder as a running lane and using variable speed limits to control the flow of traffic.
The three different types of smart motorway currently include: controlled motorways, dynamic hard shoulder running schemes and all lane running schemes.
A controlled motorway has three or more lanes with variable speed limits. These variable speed limits are displayed on overhead gantry signs - if no speed limit is displayed the national speed limit is in place. Speed cameras are used to enforce these.
