In　order　to　meet　a　variety　of　demands　of　resident　trip　and　improve　the　level　of　service　of　PT　(public　transit)　system　and　solve　the　problem　of　network　structure,　this　paper　presents　a　planning　method　for　multi-hierarchy　public　transit　route　network　that　is　based　on　the　idea　of　serving　for　district,　plan　layer　by　layer,　optimizing　for　PT　network.　On　the　assumption　that　railway　routing　planning　is　completed,　layout　planning　for　multimodal　terminals　is　implemented,　the　optimization　object　of　rapid　transit　route　is　to　maximize　network　efficiency,　and　the　optimization　object　of　bus　route　is　to　maximize　nonstop　bus　passenger　density,　and　the　optimization　object　of　branch　bus　route　is　to　maximize　the　numbers　of　stops　covered　by　bus　route.　Every　hierarchy　network＇s　constraint　condition　and　location　optimization　method　is　different,　and　its　planning　flow　is　built.
