This　paper　establishes　disaggregate　travel　mode　choice　models　to　analyze　the　bus　choice　behavior　of　walking　travel　groups　based　on　utility　theory.　The　preference　survey　of　travel　behavior　for　walking　groups　is　conducted　in　Ji＇nan　City　of　China.　Travel　time　and　bus　comfort　are　chosen　as　the　two　important　factors　to　analyze　the　mode　choice　intent　to　taking　bus　for　walking　travel　groups.　The　research　found　that:　(1)　the　walking　travel　groups　who　are　more　sensitive　to　the　change　of　bus　fare　are　short　distance　travelers;　and,　(2)　the　sensitive　range　of　travel　time　for　walking　travel　groups　is　between　0　minutes　and　30　minutes.　The　research　conclusions　will　provide　the　basis　of　decision-making　for　traffic　policy　and　enhancing　the　bus　share　ratio.　©　2014　American　Society　of　Civil　Engineers.
