On　the　basis　of　the　present　rail　transit　and　BRT　network,　this　paper　presents　a　planning　method　for　bus　route　network,　which　is　established　by　presenting　a　transfer　station　attraction　coefficient.　This　coefficient　is　used　to　adjust　the　link　travel　time　of　bus　route　that　borders　with　rail　transit　transfer　centres,　BRT　stop　or　terminals.　Based　on　the　object　of　direct　passenger　flow　density　maximum　and　by　using　the　shortest　path　algorithm,　bus　route　network　is　designed.　Through　adjusting　the　link　travel　time,　the　bus　route　passes　or　is　closer　to　transfer　station　so　as　to　improve　the　attraction　ability　of　mass　rapid　transit.　This　bus　route　also　plays　an　important　role　in　picking　up　and　delivering　passengers　to　mass　rapid　transit　stations,　BRT　stops　or　terminals　and　in　improving　the　profits　of　transit　companies.
