Smart Motorways are highways that use technology to manage traffic flow and increase capacity by opening and closing lanes depending on the volume of traffic. They were first introduced in the UK in 2006 and have since been implemented on major highways across the country. Their aim is to reduce congestion and improve journey times for motorists.
However, Smart Motorways have come under scrutiny due to safety concerns. They work by converting the hard shoulder into a running lane during peak traffic hours, which means that in the event of an accident or breakdown there is no safe place for motorists to stop. This has led to a number of fatalities on Smart Motorways, with drivers and passengers being struck by moving vehicles as they attempted to exit their cars.
The issue has been particularly acute in London, where Smart Motorways have been blamed for multiple deaths and serious injuries. In response to these concerns, Transport for London (TfL) has announced plans to remove all Smart Motorways in the capital over the next few years.
Why are Smart Motorways being removed in London?
In January 2021, TfL announced that it would remove all Smart Motorways from the capital over the next few years. The decision came after a review of the technology, which identified a number of safety concerns. Smart Motorways were found to be particularly dangerous in urban areas like London, where there is a high volume of traffic and limited space.
The review highlighted several key issues with Smart Motorways, the most pressing of which is the lack of a hard shoulder. This means that if a driver breaks down or is involved in an accident, there is no safe place for them to pull over. Instead, they are forced to exit their vehicle and stand in the live lane, putting themselves at risk of being hit by passing motorists.
The review also found that there was a lack of understanding among the general public about how Smart Motorways work, and their associated risks. Many drivers were unaware that in the event of an emergency they should exit their vehicle via the left-hand doors, away from the traffic.
Finally, the report highlighted the importance of ensuring that all Smart Motorways are equipped with the necessary technology to detect stopped vehicles and alert drivers to slowing traffic. Many of the Smart Motorways in London were found to be lacking in this regard, increasing the risk of accidents and congestion.
What will replace Smart Motorways in London?
TfL has not yet announced what will replace Smart Motorways in London. However, there are several options under consideration, including the construction of new motorways with hard shoulders, and the implementation of new technologies to improve traffic flow and reduce congestion.
One possible alternative is the introduction of Tunnel Control Centres, which would use sophisticated technology to monitor traffic flow, adjust speed limits and lane usage, and coordinate with emergency services in the event of an accident or breakdown.
Another potential option is the use of Variable Message Signs (VMS) to provide real-time information to drivers about traffic conditions, lane closures, and speed limits. VMS can be used to alert motorists to incidents or accidents ahead, and to advise them on the best route to take to avoid congestion. This would facilitate a more dynamic and responsive traffic system, reducing the risk of accidents and improving journey times for all road users.
Whatever replacement is chosen, it is clear that Smart Motorways are no longer seen as a safe or effective solution for managing traffic in London. By removing them from the capital’s roads, TfL hopes to improve safety, reduce congestion, and create a more efficient transport system for all Londoners.
