Risk　assessment　of　road　segments　is　the　foundation　of　risk　assessment　of　transport　route　risk.　So　far,　most　researches　on　transport　route　risk　are　focused　on　hazardous　material　transportation,　but　the　method　of　those　researches　can　not　be　directly　used　in　ordinary　goods　transportation.　The　effort　of　this　paper　will　be　made　to　study　transport　road　segment　risk　of　ordinary　goods　transportation.　An　index　system　of　transport　road　segment　risk　is　built　on　the　analysis　of　road　segments　system,　and　the　risk　assessment　of　ordinary　goods　transportation　on　a　road　segment　is　achieved　on　the　bases　of　analytical　hierarchy　process　(AHP)　and　a　fuzzy　decision　method　based　on　continuous-interval-argument　ordered　weighted　average　(COWA)　operator.　The　whole　process　of　the　risk　assessment　is　not　only　useful　to　evaluate　transport　route　risk,　but　also　facilitate　the　risk　assessment　of　intermodal　transportation.　©　2011　IEEE.
