Abstract

Highlights: We conducted a state-of-the-art RP and SP survey and presented its methodology with a total of 5, 143 respondents, which covers 52, 731 observations. The development of On-Demand Transport (ODT) is popular in many cities. Urban Air Mobility (UAM) will become a new alternative mode of transportation. This paper presents the travel behavior of respondents in each mode of transportation. We explored willingness to pay (WTP): VTTS, VTAT, elasticity, and the preference of all choice alternatives, including ODT and UAM using pooled SP and RP data sets. Abstract: The research presented in this paper analyzed two data sets Revealed Preference (RP) and Stated Preference (SP), obtained with a new travel diary and mode choice survey. This survey, called Mobility Jakarta, combined both RP and SP parts and was conducted in the Greater Jakarta region. This is the first survey that collected responses from a substantial sample of the whole metropolitan area population. We estimated the discrete choice model pooling SP and RP data sets. We explored the Willingness To Pay, e.g., the Value of Travel Time Savings, and the elasticity for all mode choice alternatives, including On-Demand Transport and Urban Air Mobility.
