To　improve　the　comprehensive　operation　level　of　non-signalized　intersection　and　reduce　the　occurrence　of　traffic　accident　and　to　solve　the　problem　of　facilities　of　traffic　safety　at　non-signalized　intersection　in　national　and　provincial　main　roads,　a　comprehensive　effectiveness　evaluation　method　was　proposed　for　the　combination　alternative　of　traffic　safety　facilities　at　non-signalized　intersection.　An　effective　evaluation　for　the　combination　of　traffic　safety　facilities　at　level　crossing　was　conducted　based　on　microscopic　driving　behavioral　data　through　driving　simulation　technology.　Taking　intersections　in　Anle　Road,　101　National　Road　as　an　example,　the　simulated　driving　experimental　scenarios　under　four　sets　of　alternatives　with　different　facilities　combination　were　constructed.　Nine　evaluation　indicators　were　selected　from　three　levels　of　the　driving　behavior　data　of　the　experiment.　Technique　for　order　preference　by　similarity　to　an　ideal　solution　(TOPSIS)　evaluation　method　was　adopted　to　quantify　the　single-objective　evaluation　of　combination　alternatives　from　the　three　aspects　of　intersection　safety,　predictability　and　comfortability.　Finally,　a　grey　situation　decision-making　method　was　selected　to　comprehensively　conduct　a　multi-objective　evaluation　on　the　non-signalized　intersection.　The　research　findings　show　that　this　evaluation　method　is　relatively　practical　to　solving　the　problem　of　the　installation　and　the　combination　of　facilities　at　non-signalized　intersection.　It　can　also　perform　a　comprehensive　evaluation　on　combination　alternative　of　traffic　safety　facilities　at　non-signalized　intersection,　which　lays　the　foundation　for　the　further　improvement　of　guidelines　on　traffic　safety　facilities　installation　and　combination　at　main　road　intersections.　©　2019,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
