Valuing Manggarai Station – Soekarno-Hatta International Airport Rail Link Using Stated Preference Approach
Abstract: This study attempts
to identify the characteristics and preference of the SHIA airport travelers,
estimate the subjective value of in-vehicle time and waiting time by providing
choice experiments regarding the available modes in combination with the
Airport Rail Link (ARL) service as hypothetical situation, analyze how the
values vary according to the socio-demographics of respondents and forecasting
the mode sharing and the elasticity based on several scenarios. Five hundred
respondents as potential demand for the airport access mode from both the
online and on-field survey in Jakarta value reliability as the most important
factors followed by comfort, journey time, fares and safety, while the most
reliable journey according to the respondents is by train.
After various attempts to best analyze the data, statistically
significant result is obtained from MNL and Nested models. The values of IVT
vary between 632 Rupiah/Minute and 871 Rupiah/Minutes, the values of waiting
time vary between 901 Rupiah/Minute and 1,504 Rupiah/Minute. The results of
unobserved parameters from the alternative modes are satisfactory negative for
bus and positive for ARL alternative.
The segmented models results vary that the value of male is higher than
female, the value of high income is higher than low income, the values of taxi
user is higher than car user, the value of business traveler is higher than
leisure and commuter traveler, the value of self-finance journey is lower than
the journey paid by the company. With the standard level of service, the
probability result of mode sharing shows that the majority of respondents will
use the train service (40.99%), followed by the other modes: bus (30.90%), car
(16.52%), and taxi (11.59%).
