摘要：	National Highways has published its second annual update on progress against the 2020 smart motorways Stocktake and Action Plan. The update shows that conventional motorways have lower rates of personal injury collision (PIC) but higher fatality weighted injury (FWI) and killed and seriously injured (KSI) rates than each type of smart motorway. Howev.er, all lane running (ALR) sections, where the hard shoulder has been converted to a permanent running lane, continue to have higher rates of serious casualties than other types of smart motorway. They have a KSI rate of 1.38 per hundred million vehicle miles, compared to 1.17 for dynamic hard shoulder schemes, where the hard shoulder is used for traffic in busy periods, and 1.30 for controlled motorways, which use smart motorway technology but keep the hard shoulder. When vehicles stop on the motorway PIC, FWI and KSI rates are lower on motorways with a permanent hard shoulder than motorways without one, with controlled motorways being the safest In fact, stopped drivers are twice as likely to be killed or seriously injured on a smart motorway than on a traditional motorway with a hard shoulder.
