As　one　of　the　most　important　components　of　the　transportation　system,　the　urban　public　transportation　terminal　is　essentially　researched　by　the　transfer　demand.　In　this　work,　the　traffic　network　was　abstracted　as　a　hierarchical　network.　Based　on　the　network　equilibrium　theory,　the　traveler＇s　behavior　of　choosing　travel　mode　was　analyzed.　The　variational　inequality　model　and　the　calculation　method　of　transfer　demand　were　presented.　According　to　the　data　of　O　(origin)-D　(destination)　matrix　and　the　changes　of　external　variables,　the　changes　of　terminal　transfer　demand　can　be　obtained　and　these　changes　were　analyzed　for　improving　the　transfer　efficiency.　Finally,　a　numerical　example　was　studied　and　the　relationship　between　the　changes　of　external　variables　and　transfer　demand　in　terminal　was　explored.　The　result　has　verified　the　feasibility　of　the　proposed　calculation　method.　This　research　could　provide　a　useful　reference　for　research　on　the　transfer　demand　in　urban　public　transportation　terminal.
