Traffic　safety　is　a　critical　issue.　The　safety　evaluation　of　roads　and　traffic　facilities　lacks　systematic　evaluation　methods.　This　study　aims　at　researching　safety　features　of　road　and　traffic　facilities　at　the　entrance　of　the　interchange　area　for　safety　evaluation　and　improvement　of　road　traffic　facilities.　Firstly,　this　study　divided　road　types　and　selected　road　conditions.　This　study　takes　interchange　as　an　example　to　analyze　the　impact　of　road　and　traffic　facilities　500　meters　in　front　of　the　interchange　entrance　on　traffic　safety.　Secondly,　this　study　selected　road　facilities　(number　of　lanes,　traffic　disturbance),　traffic　facilities　(the　complexity　of　diagrammatic　guide　signs,　advance　guide　system,　the　number　of　warning　sign)　and　risk　driving　behavior　to　explore　the　relationship　between　the　position　of　risk　driving　events　and　road　traffic　facilities,　and　to　observe　the　impact　of　road　and　traffic　facilities　on　safety.　The　research　results　can　be　used　for　reference　in　the　construction　of　new　road　traffic　facilities　and　provide　technical　support　for　the　establishment　of　related　management　departments.
