A joint choice decision model of intra-household interaction-based motorcycle mode and departure time in Yogyakarta, Indonesia

The motorcycle-based joint trip between family members in a household becomes a common phenomenon in responding to unreliable public transport. This study aims to model the joint choice decision between intra-household interaction-based joint trip using motorcycle and departure time. With the data collected from 416 workers using the motorcycles in Yogyakarta, Indonesia, a cross-nested logit model was developed to explore the individual and household characteristics, work-and travel-related characteristics influencing household-based joint trip and departure time. The model result reveals that motorcyclists are more likely to change their departure time rather than an intra-household-based joint trip. Motorcyclists departing on a peak hour have a lower elasticity due to the alteration of travel time and travel cost than motorcyclists leaving on an off-peak hour. In a case of the off-peak departure time, motorcyclists leaving home to work by driving alone are more elastic for a change of travel cost than motorcyclists departing to work with their family member.
