In　order　to　re-estimate　the　crosswalk　capacity　under　mixed　traffic　condition,　a　new　approach　to　calculating　the　crosswalk　capacity　at　signalized　intersections　with　channelized　islands　is　demonstrated.　Channelized　intersections　designate　the　intended　vehicle　paths　using　pavement　markings　or　raised　islands.　Channelization　is　widely　used　for　crosswalks,　particularly　when　there　is　a　non-motorized　traffic　(e.g.,　pedestrians　and　bicycles)　waiting　zone.　The　capacity　of　crosswalk　is　changed　due　to　the　two　distinctive　stages　when　non-motorized　traffic　goes　through　signalized　intersections　during　the　green　time.　The　capacity　calculation　model　is　based　on　the　dynamics　area　conversion　of　pedestrians,　bicycles,　electric　bicycles　and　conversion　of　reach　area.　The　model　is　then　calibrated　using　the　field　data　collected　at　several　signalized　intersections　in　the　city　of　Fuzhou.　The　proposed　method　in　this　paper　can　better　estimate　the　capacity　of　crosswalk.　©　right.
