Smart motorways are designed to optimize traffic flow and improve safety on the road. One of the key features of smart motorways is the ability to convert the hard shoulder into an active running lane during times of high traffic congestion. This adjustment helps to alleviate traffic jams by increasing the number of lanes available for use, thus allowing for better management of vehicle flow.

Using the hard shoulder as a running lane typically occurs under specific conditions where traffic is heavy and additional lane capacity is needed. Advanced systems and technology, including Variable Speed Limits and Traffic Management, monitor road conditions and adjust accordingly to ensure safety.

By allowing the hard shoulder to function as a lane, smart motorways can effectively reduce delays and improve overall travel times for drivers. This approach demonstrates the adaptability of modern road systems in addressing fluctuating traffic demands.
