With　the　increase　of　urban　scale　and　rapid　development　of　transportation,　intercity　travel　is　more　convenient　and　plays　a　crucial　role　in　the　urban　transportation　system.　Traditional　travel　survey　methods　are　difficult　to　apply　to　the　research　between　hubs.　This　paper　proposes　a　method　based　on　mobile　phone　data　to　calculate　the　passenger　travel　OD　between　the　Beijing-Tianjin-Hebei　urban　megalopolis　hubs,　and　analyzes　the　spatial　and　temporal　law　of　passenger　travel.　Firstly,　we　propose　an　approach　to　extract　passenger　trips　information　among　hubs　from　mobile　phone　data.　Secondly,　we　describe　the　spatiotemporal　travel　characteristics　of　passengers　at　the　Beijing　West　Railway　Station　-　Zhengding　Airport.　The　results　show　that　mobile　phone　data　has　great　potential　for　studying　passenger　travel　among　megalopolis.　©　2020　ASCE.
