The　existing　transit　ridership　models　describe　land　use　with　indexes　such　as　population,　employment　and　land　use　area,　these　indexes　can＇t　describe　the　diversity　and　complexity　of　land　use　development,　thus　make　it　difficult　to　reveal　the　influence　mechanism　of　mixed　land　use　on　travel　demand.　This　paper　quantifies　the　precise　land　use　characteristics　of　Beijing　transit　station　catchment　areas　using　POIs　(points　of　interest)　extract　from　an　electronic　map.　Through　the　regression　analysis　of　precise　land　use　and　transit　station　boarding　volume,　a　direct　ridership　model　is　built　based　on　the　influence　mechanism　analysis　of　land　use,　traffic　and　location　factors　on　transit　ridership.　Following　validation　shows　the　prediction　accuracy　of　the　proposed　model　meets　expectation,　reveals　the　strong　correlation　between　land　use　and　transit　ridership.　©,　2015　All　right　reserved.
