摘要：	Fatality rates on all lane running (ALR) 'smart motorways' have exceeded those on conventional motorways for the past two years, with 15 people now confirmed to have died on motorways without a permanent hard shoulder in 2019. Data produced for Highways England's progress report on last year's smart motorway 'stocktake' shows that five-year average fatality rates for 2015-19 were 0.15 per hundred million vehicle miles (hmvm) for conventional motorways, 0.12 for ALR schemes, 0.08 for dynamic hard shoulder schemes and 0.06 for controlled motorways. In its submission to the Transport Select Committee's inquiry into smart motorways, the Department for Transport (DfT) said Highways England had compiled the figures on a five-year basis 'because single-year figures are too low and variable to draw consistent conclusions from'. However, while live lane fatality rates were lower on ALR schemes than on conventional motorways for the first three years, ALR fatality rates overtook those on conventional motorways in 2018 and 2019. In 2018, fatalities on ALR schemes were 0.19 per hmvm, compared to 0.14 on conventional motorways. In 2019, fatality rates on both types of motorway fell, with ALR schemes recording 0.14 per hmvm, still higher than conventional motorways at 0.13. The fatality rate on controlled motorways was 0.07 in 2019, down from 0.11, significantly lower than on ALR and conventional motorways.
