A Series of Three Case Studies on the Semi-Automation of Activity Travel Diary Generation Using Smartphones
The growing need of acquiring data that is useful for travel behaviour analysis led scientists to pursue new ways of obtaining travel diaries from large groups of people. The most promising alternative to traditional (declarative) travel diary collection methods are those that rely on collecting trajectories from individuals and then extract travel diary semantics from the trajectories. However, most studies report on routines specific to the post-processing of data, and seldom focus on data collection. Even the few studies that deal explicitly with data collection describe the final state of the collection system, but do not go at the lengths that are required to describe the decision that were taken to bring the system to its current state. This leads to a considerable amount of work that is needed for designing collection systems that are often undocumented, which impedes the reuse of the aforementioned systems. In light of the aforementioned problems, this paper presents a series of three case studies behind the continuous development of MEILI, a travel diary collection, annotation and automation system, in an effort to: 1) illustrate the utility of the developed system to collect travel diaries, 2) identify how MEILI and other semi-automatic travel diaries collection systems can be improved, and 3) propose MEILI as an open source system that has the potential of being improved into a widely available semi-automated travel diary collection system.
