2.2DescriptionofMobilePhoneData
Asof2014,about57millionpeopleownedmobilephonesinKorea,whichisequalto1.13mobilephonesperpersononaverage.Thus,mostofadultsandteenagershaveamobilephone.Forthisanalysis,weusedtheSKT’smobilephonedata.TheoriginalmobilephonerecordswerecollectedandpreprocessedbySKT.First,everymobilephonesignalisreceivedbyanearbycellulartower,andtheexistinglocationandtimeinformationisstoredinaserver.Mobiletrafficisidentifiedbyphonecalls,SMSmessages,notificationsorupdatesfromapps,orInternet
connections.Alocationofmobilephoneisinitiallyidentifiedbyacellulartower,albeitcoveringalargeareaofatleast2,500m2.Thus,SKTfurthersegregatedtheidentifiedlocationintoasquarecellarea(50mby50m),basedonaspatialcorrelationoflanduseandtheweightsofthetotalfloorareasofbuildingtypes.SKT,oneofthreemobilephonetelecommunicationoperatorsinKorea,consistentlyheldabouthalfofthecountry’stotalmobilephonememberships.Beforeprovidingthedataset,SKTfurtherexpandedtheirmobilephonerecordstoincludethetotalmobilephoneusersinKorea,usingthecountry’smarketsharerate.Thisisahugeadvantageforthepopulationandmobilityanalysisbecausethedatasetrepresentsthetotalpopulationofmobilephoneusers.

3Analysis
3.1ChangesofActivityPopulation
Weanalyzedoneweekofmobilephonedataineachyearof2015
and2016.Activitypopulationisdefinedasthenumberofmobilephoneusersinthispaper,whoarelocatedina50mcell.Tocompareactivitypopulationbeforeandaftertheopeningofanewshoppingmall,weneedthenumberofpopulationvisitingtoashoppingmall.However,whenusingmobilephonedata,itisverydifficulttoidentifywhetherpeopleareinsideashoppingmallwithpurposesofvisingthemall,becausethedatadoesnothaveanactivityortrippurposeandtheexactdestination.Thus,weextractthenumberofactivitypopulationlocatedwithinacertaincatchmentareainsteadofinacell.Thisstudyspecificallyinterestedinthecomparisonofchangesofactivitypopulation,includingshoppersinthemallaswellasvisitorsaroundthemall.Forthisreason,weanalyzedactivitypopulationincatchmentareasrangedfrom100mto300mwithanintervalof50m,andwedetermined300masthereasonablecatchmentareainthispaper.
First,weexaminedactivitypatternsbydayoftheweek,andfoundthattheywereverysimilartoallshoppingmalls.ThenumberofactivitypopulationgraduallyincreasedfromMondaytoFriday,anddroppedonweekends.ThepeakactivitypopulationwasappearedonFriday.However,activitypatternsin2016showedslightlydifferentpatternsin2015.ThenumberofactivitypopulationonSaturdaywaslowerthanthatofMondayin2015.However,thenumberofpopulationonSaturdaywasverysimilarthatofMondayin2016.Allshoppingmallsshowedthese
patterns.
Wecomparedaveragedailyactivitypopulationinfourmallsin2015and2016.Wecomparedaveragedailyactivitypopulationwithin300mbeforeandafterthenewshoppingmall.ActivitypopulationintheHyundaishoppingmallincreasedby103%in2016,whilethatoftheAKshoppingmallslightlydecreasedby3%.TheAKmallisthenearestshoppingmallfromtheHyundaimall,locatingin1.3kmawayfromtheeast-southoftheHyundaimall.Thus,theopeningoftheHyundaimallnegativelyimpactedtheAKmall.Ontheotherhand,activitypopulationinbothLotteandNCmallsincreasedby8%and78%,respectivelyin2016.Thedistancesare1.6kmand2.4km,respectively,awayfromtheHyundaimall.So,itisinterestingthattheNCmallwasnotnegativelyimpactedbytheHyundaimall.
Weanalyzedshowsthepopulationdifferencesofthreeshoppingmallsineachcatchmentareas.Inallcatchmentareas,activitypopulationin2016intheAKmallweredecreasedcomparedtothosein2015,whilethoseintheHyundaimallwereincreased.TheactivitypopulationintheLottemalldecreasedwithin250m,whiletheyareincreasedwithin300m.
