The　number　of　fatalities　in　road　traffic　accidents　shows　a　gradual　upward　trend　in　recent　years,　and　this　has　brought　great　pressure　on　the　realization　of　China＇s　safety　objectives.　Meanwhile,　how　to　make　a　scientific　and　feasible　path　for　achieving　the　safety　objective　also　poses　a　great　challenge　to　the　existing　methods.　Therefore,　the　paper　introduces　the　objective　constraint　to　develop　a　new　inverse　data　envelopment　analysis　(DEA)　model　with　undesirable　outputs　for　ensuring　the　realization　of　safety　objective　under　the　current　technical　level.　Subsequently,　two　safety　objectives　and　two　additional　objectives　are　defined　for　China＇s　road　transportation　according　to　the　actual　requirements　of　decision　makers,　and　then　their　realization　paths　are　determined　by　using　the　new　inverse　DEA　model,　respectively.　By　analyzing　the　connections　and　differences　of　different　objectives　and　their　realization　paths,　some　useful　implications　are　summarized　to　promote　the　realization　of　the　safety　objective　of　China＇s　road　transportation:　First,　identifying　the　requirements　of　decision　makers　is　critical　for　making　the　realization　path　of　safety　objective;　second,　reducing　desirable　outputs,　increasing　inputs,　and　improving　safety　efficiency　are　the　efficient　ways　to　achieve　safety　objective;　third,　the　influence　of　technology　heterogeneity　should　be　properly　considered　in　the　process　of　making　the　realization　path　of　safety　objective.　In　general,　the　paper　provides　a　powerful　decision　support　for　achieving　the　safety　objective　of　China＇s　road　transportation.　©　2021　Elsevier　Ltd
