Characteristic of modal choice preference between bus and train from medan to kuala namu airport

Abstract

Kuala Namu International Airport started operating on July 25, 2013 to replace Polonia International Airport followed by the operation of airport train and bus as a public transport service mode. The purpose of the study was to define the characteristic of airport train and bus users how they choose both of the transportation modes and to test the sensitivity, if one of the transportation attribute are changes. The data obtained through stated preference method was modelled by using binary logit and probit models. From these two models, the probability of using airport train and bus transportation can be known. The result of analysis showed the equations of the function of utility difference of airport train and bus: UKAB-BB = 2,606 - 0,028X1 - 0,007X2 - 0,014X3 - 0,016X4 + 0,044X5, where X1, (cost attribute), X2 (time attribute), X3 (headway attribute), X4 (access attribute) and X5 (service attribute)..
