Abstract:We describe the design and evaluation of a system named Quantified Traveler (QT). QT is a Computational Travel Feedback System. Travel Feedback is an established programmatic method whereby travelers record travel in diaries, and meet with a counselor who guides her to alternate mode or trip decisions that are more sustainable or otherwise beneficial to society, while still meeting the subject's mobility needs. QT is a computation surrogate for the counselor. Since counselor costs can limit the size of travel … Show more
“…Hence, the factors that maximize behavioural change according to various behavioural theories (goal setting, social comparison) are not uniformly appreciated by participants, and may potentially lead to drop out or not signing up. Finally, a contradiction was reported between the consortium's aim to change participants' behaviour but also their attitudes, and participants' autonomous decision making (Jariyasunant et al 2015). Direct questions regarding the effects of fossil fuels on greenhouse effect, asked before and after the study, showed a decline in reported awareness.…”

“…Travellers may be compared to the average of the other participants (sometimes called the community), or to self-set goals. In this section, we discuss the activity system based on a number of reported studies of travel feedback apps (Gabrielli and Maimone 2013;Wells et al 2014;Broll et al 2012;Meloni and di Teulada 2015;Jariyasunant et al 2015;Brazil et al 2013). …”
“…From the traveller's viewpoint, outcomes may relate to her travel behaviour. Various studies report that travellers' behaviour in response to the App changed toward increased use of environmental travel modes, and less car use (Gabrielli and Maimone 2013;Jariyasunant et al 2015). The studies are unclear about whether participants feel that their travel has improved and become more pleasant.…”
Section: Outcomes and Travel Implicationsmentioning
With the continuous advancement of (mobile) ICT devices and applications, their impact on travel, activities and time use becomes more diverse. This holds in particular for apps developed for mobile devices (smartphones). In this paper, we argue that the effect of ICT on travel and activities should be analysed at the level of a single specific device or application, rather than for broad classes of ICT devices. We propose activity theory as a framework to analyse the impact of smartphone apps on travel and activities. Activity theory describes how subjects apply tools (such as apps) to work on an object and achieve an outcome that is in line with the subject's motive. The application of the tool is embedded in an activity system which includes a community, formal and informal rules and in which a division of labour exists. We apply activity theory to analyse the effects of Whatsapp and travel feedback apps, based on existing literature about these apps. The analyses suggest that the activity systems of each app differ greatly in terms of object, motive, outcomes, community and rules, with implications for their use and impact. Both apps have an impact on travel, but differ with respect to whether this effect is intentional. For both apps contradictions in the activity system can be identified, which may give rise to further development of the activity system. These seem, however, to be largest for travel feedback apps. Based on our exploration, we argue that quantitative research on the impact of apps should be complemented by qualitative research based on activity theory. In particular, activity theory may help to gain a better understanding of underlying mechanism by which apps influence travel, to strengthen the theoretical underpinning and interpretation of the results of quantitative research and to explore changes in the development and use of apps and their impact on travel behaviour.

“…A large number of studies has focused on the recording and analysis of mobility and activity data using smartphones, usually by utilizing location (GPS) and accelerometer data ( [18], [19], [20], [21], [22], [23], [24], [25], [26]). Issues such as suitability of sensors for activity recognition [27], accuracy of transport mode classification [28], [29] and energy consumption of the app [30] are well researched areas.…”
Section: Large Scale Automatic Mobility Monitoringmentioning
Abstract-The large interest in analyzing one's own fitness led to the development of more and more powerful smartphone applications. Most are capable of tracking a user's position and mode of locomotion, data that do not only reflect personal health, but also mobility choices. A large field of research is concerned with mobility analysis and planning for a variety of reasons, including sustainable transport. Collecting data on mobility behavior using fitness tracker apps is a tempting choice, because they include many of the desired functions, most people own a smartphone and installing a fitness tracker is quick and convenient. However, as their original focus is on measuring fitness behavior, there are a number of difficulties in their usage for mobility tracking. In this paper we denote the various challenges we faced when deploying GoEco! Tracker (an app using the Moves R fitness tracker to collect mobility measurements), and provide an analysis on how to best overcome them. Finally, we summarize findings after one month of large scale testing with a few hundred users within the GoEco! living lab performed in Switzerland.
“…The measures reported back to subjects often include reports, per mode, of quantifiable aspects such as cost, calories consumed or CO 2 produced [8].…”
A feasibility study of the effect of phone-based feedback of other commuters' subjective experiences on driver intentions to change Abstract. Encouraging people to make sustainable transport choices remains a global challenge and many interventions have been attempted. This study investigated the reflection on own/others' subjective experiences (SE) as an intervention using a smartphone application as the intervention tool. Participants were car drivers and used the app to automatically capture and reflect on their commute journeys and experiences. The experimental group were also able to reflect upon others' experiences across car, walk and cycle modes. Others' experiences were designed based on a previous self-report study. Results of the study showed that quantitative measures of intentions to change were not affected by the intervention but that qualitative data showed that the positive experience of the active transport modes did bring about reflection on behaviour and a potential influence on opinions and intentions which warrants further study.
