Focusing　on　the　intersections　of　Beijing＇s　central　urban　area,　the　paper　studies　the　traffic　facilities,　motor　vehicles　volume,　pedestrian　volume,　pedestrian　traffic　conflict,　pedestrian　traffic　law　violation　rates　and　carries　out　survey.　Based　on　extensive　survey　data　and　historical　traffic　data,　the　paper　proofs　that　the　major　factor　leading　to　the　pedestrian　traffic　conflicts　is　pedestrian　violation　of　the　traffic　law,　followed　by　lack　of　reasonable　facilities　crossing　the　streets.　According　to　the　causes　of　the　traffic　accidents,　the　paper　puts　forward　appropriate　measures　to　improve　pedestrian　safety,　including　improving　pedestrian　traffic　compliance　rate,　adding　more　crossing　streets　facilities　for　pedestrian.　For　quantitative　evaluation　of　pedestrian　safety,　pedestrian　traffic　conflict　evaluation　model　at　urban　road　intersections　should　be　established,　and　the　model　parameters　should　be　calibrated.　The　result　of　this　paper　has　an　important　significance　for　easing　traffic　congestions　in　big　cities,　and　improving　traffic　safety.　©　2011　ASCE.
