Observing and modeling Interdependencies between ICT use and travel in the presence of multi-service transport platform: A case from Jakarta, Indonesia

Abstract

The concept of time-space constraints has been discussed in many decades emphasizes that time and space delimit individual’s opportunities to participate in activities and travel, imposing important restrictions on people’s access and mobility. Base on the time-space constraints concept, several activity-based models have been developed together with the assumption that travel is a derived demand of activity engagement at destination. On the other hand, several researchers have discussed how the usage of ICT affects travel behavior from various angles such as how ICT affects the mode choice, route choice, and scheduling. However, most studies focus on the overall impact of ICT on activity-travel behavior, while they do not consider the context-dependent factors affecting ICT use and activity-travel behavior. In this study, we aim to (1) develop a comprehensive travel survey scheme to observe interdependencies between ICT use and travel behavior and report the results, and (2) extend an existing dynamic discrete choice activity-travel model to incorporate the impacts of ICT use on activity-travel patterns. This study focuses on a situation in Indonesia where multi-service transport platforms (MSTPs), particularly GOJEK and Grab, have been widely used and have now become a vital part of people’s daily lives, leading to unignorably changes in people’s travel behavior and activity patterns. With the presence of the MSTPs, the way of interacting between supply-side (merchants) and demand-side (users) might change, essentially because the platform would relax users’ time and space constraints to reach the services. We have developed a comprehensive two-week travel-ICT use survey to capture interdependencies between ICT use and travel in such a context and will conduct the survey with more than 300 respondents in South Jakarta, Indonesia. We have attempted to develop a survey and modeling framework to comprehensively understand the impacts of MSTPs on travel behavior with a focus on Indonesia where MSTPs services have been widely used and have now become a vital part of people’s daily lives. We believe that it is worth sharing the proposed framework together with empirical findings with other travel behavior scholars, since the MSTPs has been showing both unignorably positive and negative impacts on the society in Indonesia, and putting the MSTPs on a proper position of entire transport systems is one of the major challenges we face.
