Road sense
In contemporary marketing parlance, “smart” means better. We have smart dishwashers with in-built wi-fi connections (that also wash dishes) and smart speakers with high-definition screens (that also play music). In an increasing number of countries, we also have smart motorways, where traffic flow is controlled using artificial intelligence – that you can also drive on.
But while a mistake with the former two probably wouldn’t be fatal, the latter’s inability to deliver an improved user experience comes with a pretty hefty price. A BBC documentary found that in the UK, between 2014 and 2019, 38 people died while using smart motorways. Many campaigners consider that number to be too high.
Now, after the seemingly unstoppable rollout of such roads across the country, British MPs on parliament’s Transport Committee have called for their construction to be halted due to safety concerns. The scheme’s future looks uncertain. Conceived as a way of ameliorating congestion without the financial or ecological effects of road expansion, smart motorways were always going to be accused of putting cost before safety.
On the AI-assisted motorways, what was the hard shoulder (breakdown lane) is now a fourth lane of traffic, which can be closed if a breakdown occurs. These roads in fact result in fewer deaths: between 2015 and 2018, the fatal-casualty rate on smart motorways without a permanent hard shoulder was lower than on those with one. Yet though fatalities are lower, accidents can be more traumatic. Deaths that occur after drivers break down and are effectively stranded have been particularly distressing for bereaved relatives and fear-inducing for many road users.
Using any form of high-speed transportation requires a soupçon of cognitive dissonance but the thought of breaking down on a road at the mercy of four lanes of fast-moving traffic without a refuge area is horrific beyond belief. To label something “smart” in such circumstances is an insult to both man and machine. Minimising environmental damage and improving traffic flow is an admirable aim but unless the technology to do so is improved, smart motorways should be left in the lay-by.
