This　paper　documents　the　speed　reduction　impacts　of　intersection　control　beacon　on　rural　highway　on　Xu　song　road　of　Beijing　City,　China.　To　determine　the　effect　of　intersection　control　beacon　on　stopping　behaviors　of　drivers,　a　camera　was　used　to　collect　valid　samples　at　four　times.　After　data　preparation,　there　were　200　valid　samples.　In　order　to　research　the　changing　of　vehicle　speed　and　relationship　of　speed　and　distance,　Lagrange＇s　interpolation　and　Analyses　of　Variance　(ANOVA)　methods　were　used　on　the　speed　data　to　get　the　mean　diagram　of　mean　speeds　and　the　statistically　significantce　result　of　distance　and　speed.　The　result　showed　that　on　rural　highway　on　named　Xu　song　road　of　Beijing　City　with　intersection　control　beacon,　the　speed　of　vehicles　waned　decreased　12.87%,　moreover,　distance　has　a　significant　effects　on　speed.　In　the　distance　of　speed　beginning　to　decrease　was　13　meters　from　intersection　stopping　bar,　speed　changed　significantly　at　about　1.5　merters　away　from　the　stopping　bar　with,　significantce　level　(P)　is　0.03,　lower　than　criterion　significance　significant　level　(a=　0.05).　©　2011　IEEE.
