Priority　assumption　for　non-motorized　vehicle　or　pedestrian　cannot　reflect　the　actual　situation　at　the　conflict　zone　of　channelized　islands.　Therefore,　this　paper　describes　the　vehicle　closure　effect.　Based　on　conflict　technique　method,　a　new　model　to　calculate　the　actual　capacity　of　right-turn　lane　at　signalized　intersections　with　channelized　islands　was　proposed.　The　factors　such　as　the　signal　control,　the　mixed　flow　rate　of　non-motorized　vehicles　and　pedestrians,　the　crossing　time　of　non-motorized　vehicle　and　pedestrian　group,　the　number　of　a　non-motorized　vehicle　and　pedestrian　group,　and　the　width　of　crosswalk　were　considered.　The　new　model　was　calibrated　and　tested　using　the　field　data　of　Fuzhou.　The　result　shows　that　the　proposed　method　can　better　reflect　the　actual　operating　situation　of　the　conflict　zone　of　channelized　islands.　©,　2015,　Beijing　University　of　Technology.　All　right　reserved.
