The　term　＇equality　＇　refers　to　the　fairness　of　rights　or　resource　distribution　among　social　group　members,　which　is　crucial　for　traffic　planning.　The　accessibility　of　public　transport　reflects　whether　residents　of　corresponding　geographical　analysis　unit　have　reasonable　access　to　public　transports　given　the　size　of　their　population.　Public　taxi　service　(including　both　ride-hailing　taxi　and　traditional　taxi)　is　the　primary　means　to　meet　urban　residents’personalized　daily　demand　for　public　transport.　Exploring　the　equality　of　public　taxi　services　can　provide　support　for　optimizing　personalized　travel　service　in　urban　public　travel.　In　this　study,　based　on　the　taxi　trajectory　and　dynamic　population　data　of　Xiamen,　we　used　Gini　coefficient　and　Theil　index　to　calculate　the　equality　of　taxi　service　for　three　types　of　taxi　service,　i.e.,　cruise　only,　ride-hailing　only,　and　mixed　receiving　taxi　service.　Then　we　analyzed　the　contribution　of　urban　functional　areas　to　equality　of　tax　service　and　extracted　areas　with　potential　inequity.　The　results　show　that　the　proposed　method　can　quantify　the　inequality　of　different　taxi　service　and　its　changes　under　the　context　of　COVID-19,　based　on　the　reclassification　of　taxis　service.　Specifically,　(1)　after　the　COVID-19　outbreak,　the　number　of　vehicles　providing　ride-hailing　service　decreased　by　18.8%　in　Xiamen,　with　a　10%　increase　in　service　inequality　relative　to　the　dynamic　population,　while　the　number　of　taxis　using　cruising　only　to　pick　up　orders　remained　relatively　stable,　and　the　inequality　was　also　at　a　high　level　constantly;　(2)　In　Xiamen　city　the　overall　inequality　of　ride-hailing　only　service　was　66%　that　of　cruise　only　service.　The　use　of　online　car　hailing　platform　improved　the　fairness　of　personalized　public　travel　services　for　urban　residents;　(3)　the　equality　of　taxi　service　differed　significantly　among　different　types　of　urban　functional　areas.　For　cruising　only　service,　57.49%　of　the　overall　inequality　was　contributed　by　commercial　land　use　in　Xiamen.　For　ride-hailing　only　service,　industrial　and　tourism　land　contributed　35.07%　and　19.32%　of　the　inequality,　respectively.　After　the　COVID-19　outbreak,　the　contribution　of　tourism　land　to　the　inequality　of　online　shopping　service　increased　significantly,　by　81.67%　compared　to　the　pre-epidemic　period;　(4)　Xiamen　City　contains　two　parts:　inside-island　and　outside-island.　The　number　of　potentially　inequitable　service　areas　was　much　larger　outside-island　than　inside-island.　Areas　with　a　low　level　of　passenger　service　but　a　high　level　dynamic　population　are　typically　located　in　the　island＇s　natural　parks,　while　areas　with　a　high　level　of　passenger　service　but　a　low　level　dynamic　population　are　located　beyond　the　island＇s　natural　parks;　(5)　Compared　with　the　results　based　on　the　dynamic　population,　the　inequality　based　on　the　static　population　assessment　was　overestimated　by　up　to　89.25%.　The　research　results　of　this　paper　demonstrate　that　the　theoretical　framework　and　analysis　method　can　systematically　reveal　the　inequality　characteristics　of　public　taxi　service,　providing　guiding　principle　in　urban　traffic　optimization.　©　2023　Journal　of　Geo-Information　Science.　All　rights　reserved.
