This　study　aims　to　explore　the　relationship　between　the　accessibility　in　the　multimodal　transportation　networks　and　the　travel　mode　choice　of　the　travelers　to　high　speed　rail　(HSR)　station.　The　accessibility　analysis　covers　four　indexes,　the　satisfaction,　the　convenience,　the　comfort　and　the　punctuality.　A　survey　questionnaire　was　designed　into　four　parts:　the　trip　survey,　the　trip　attributes,　the　travel　characteristics　and　the　travel　experience.　1784　riders　in　the　uncertain　age　groups　access　to　Beijing　South　Railway　Station　were　investigated　on　the　holiday,　the　weekend　and　the　workday.　On　the　basis　of　the　frequency　histogram　comparison,　the　relationship　between　the　explanatory　variables　in　the　different　levels　and　the　travel　mode　choice　were　determined　by　the　multinomial　logistic　model.　Meanwhile,　the　influence　of　these　factors　on　the　accessibility　to　HSR　station　in　the　multimodal　networks　was　analyzed　and　portrayed　by　the　evaluation　scores.　It　contributes　to　provide　suggestions　for　HSR　trip　accessibility　improvement.　©　2017　Hong　Kong　Society　for　Transportation　Studies　Limited.　All　rights　reserved.
