Probability Analysis of DAMRI Bus Mode Selection on the Operation of Adi Soemarmo International Airport (BIAS) Train

Adi Soemarmo International Airport railway's construction is an investment in the transportation sector expected to encourage the tourism sector in Joglosemar (Jogja-Solo-Semarang) Area. Adi Soemarmo International Airport (BIAS) train from Solo to the airport with a distance of about 13.5 km is an alternative to public transportation besides the preexisting DAMRI Bus service. For this reason, this research aims to obtain a probability value for choosing the mode between DAMRI Bus and BIAS Train. The variables used in this research were travel time, tariff, and waiting time using the stated preference technique. The primary data were then processed using logistic regression analysis to obtain the probability values. The results show that the probability value of the fastest travel time in the choice of condition one or scenario 9. The value obtained from comparing airport trains' use compared to DAMRI buses saves 17 minutes, a reduced waiting time of 22.5 minutes, and cheaper ticket costs around Rp. 10,000. There was a 99.59% increase in passenger displacement from DAMRI buses to BIAS trains from all these comparisons.
