The　rapid　growth　of　cars　has　brought　a　lot　of　parking　and　road　traffic　problems　around　large　airports.　Parking　facilities　around　the　airport　can　be　used　to　reduce　the　problem　of　excessive　concentration　of　parking　demand.　Based　on　a　survey　conducted　at　the　T3　terminal　of　Beijing　Capital　International　Airport,　this　paper　established　a　nested　logit　model　for　parking　location　and　connection　mode　choice　for　long-term　parking　travelers.　The　research　results　indicate　that　the　best　location　of　off-site　parking　facility　layout　is　within　5　km　from　the　airport.　When　the　distance　between　the　parking　facility　to　the　airport　is　more　than　10　km,　the　recommended　connection　mode　is　free　airport　rapid　rail　transit.　Long-term　parking　travelers　who　are　within　eight　districts,　with　no　companions,　long　driving　time　and　self-paid　for　parking　fee　are　more　willing　to　choose　off-site　airport　parking.　©　2016　ASCE.
