For　the　special　characteristics　of　the　behaviours　of　following，changing　lanes　and　stopping　in　the　mixed　traffic　flow　of　automated　driving　bus　and　manually　driven　cars，a　vehicle　lane-changing　model　considering　the　influence　of　automated　driving　bus　is　proposed　based　on　the　theory　of　cellular　automata　to　study　the　characteristics　of　the　mixed　traffic　flow　containing　automated　driving　bus.　Based　on　the　driving　characteristics　of　automated　vehicles　and　combined　with　the　driving　characteristics　of　buses　at　bus　stops，the　road　sections　were　divided　and　the　following　and　lane　changing　rules　for　autonomous　buses，normal　buses，and　cars　were　constructed，respectively.　Based　on　numerical　simulation　experiments，the　traffic　flow　characteristics　under　different　traffic　densities　and　bus　ratios　were　analysed.　The　results　show　that　under　the　same　road　traffic　conditions，the　bay　bus　stop　interferes　less　with　the　road　traffic，and　the　lane　changing　and　stopping　behaviours　of　the　automated　driving　bus　have　less　impact　on　the　road　traffic　than　those　of　the　normal　bus.　©　2025　Hunan　University.　All　rights　reserved.
