In　order　to　ensure　the　efficiency　of　the　vehicles　at　signalized　intersection,　many　pedestrians　crossing　environments　have　been　destroyed　in　Beijing,　＂Chinese　style　of　crossing　road＂　came　into　being.　Based　on　the　research　on　the　endurance　time　of　pedestrians　crossing　at　signalized　intersection　of　Beijing　can　ensure　the　safety　of　the　pedestrian　crossing　and　has　a　great　significance　on　improving　the　efficiency.　Moreover,　it　has　important　practical　significance　on　promoting　the　strategy　of　＂equity　priority　and　give　consideration　to　efficiency＂　and　improving　the　efficiency　of　urban　traffic　system.　According　to　the　characteristics　of　the　current　traffic　of　Beijing,　the　paper　focuses　on　the　pedestrians　crossing　illegally　who　arrive　at　the　signalized　intersection　crosswalk　waiting　area　during　the　red　light.　The　paper　uses　both　video　survey　and　manual　survey　to　collect　9,　554　samples　of　endurance　time.　The　paper　establishes　Weibull　distribution　parameter　model　of　pedestrians　crossing　endurance　time　at　signalized　intersection.　The　results　show　that　environmental　factors,　pedestrians　characteristics,　travel　time,　traffic　conditions　and　road　environment　have　great　influence　on　the　pedestrians　crossing　endurance　time.　©　2015,　Science　Press.　All　right　reserved.
