抄録

This study describes the efforts made to design and implement a smartphone-based activity-travel survey conducted in Jakarta, Indonesia, which is different from the existing surveys and their applications in the following ways: 1) it captured rich information regarding online activities; 2) it integrated context-aware stated preference (SP) surveys based on the revealed preference (RP) information collected from users, and 3) it was able to capture the trends in the use of multi-service transport platforms (MSTPs) and its effect on activity-travel behavior in a city from the global south. The key findings include (1) access to MSTPs is pivotal for users who are making decisions on trip making and online activity participation, and (2) an analysis using a panel mixed logit model on the choice of virtual and physical activities showed that the dominant factors on the choice of online activity engagement are (unobserved) individual attributes rather than contextual factors.
