This article presents the MOBIS dataset and underlying survey methods used in its collection. The MOBIS study was a nation-wide randomised controlled trial (RCT) of transport pricing in Switzerland, utilising a combination of postal recruitment, online surveys, and GPS tracking. 21,571 persons completed the first online survey, and 3680 persons completed 8 weeks of GPS tracking. Many continued tracking for over a year after the study was completed. In the field experiment, participants participated through the use of a GPS tracking app, Catch-my-Day, which logged their daily travel on different transport modes and imputed the trip segments and modes. The experiment lasted 8 weeks, bookended by two online surveys. After the first 4-week control phase, participants were split into two different treatment groups and a continued control group. An analysis of the survey participation shows that the technology is capable of supporting such an experiment on both Android and iOS, the two main mobile platforms. Significant differences in the engagement and attrition were observed between iOS and Android participants over the 8-week period. Finally, the attrition rate did not vary between treatment groups. This paper also reports on the wealth of data that are being made available for further research, which includes over 3 million trip stages and activities, labelled with transport mode and purpose respectively.

本文介绍了 MOBIS 数据集及其集合中使用的基础调查方法。MOBIS 研究是一项瑞士运输定价的全国性随机对照试验 (RCT)，结合了邮政招聘、在线调查和 GPS 跟踪。21571人完成了首次在线调查，3680人完成了8周的GPS追踪。许多人在研究完成后继续跟踪一年多。在现场实验中，参与者通过使用 GPS 跟踪应用程序 Catch-my-Day 参与其中，该应用程序记录了他们在不同交通方式上的日常旅行，并估算了旅行段和方式。实验持续了 8 周，以两次在线调查结束。在第一个 4 周的控制阶段之后，参与者被分成两个不同的治疗组和一个持续的对照组。对参与调查的分析表明，该技术能够在 Android 和 iOS 这两个主要移动平台上支持这样的实验。在 8 周期间，iOS 和 Android 参与者的参与度和流失率存在显着差异。最后，治疗组之间的损耗率没有变化。本文还报告了可供进一步研究的大量数据，其中包括超过 300 万个旅行阶段和活动，分别标有交通方式和目的。在 8 周期间，iOS 和 Android 参与者的参与度和流失率存在显着差异。最后，治疗组之间的损耗率没有变化。本文还报告了可供进一步研究的大量数据，其中包括超过 300 万个旅行阶段和活动，分别标有交通方式和目的。在 8 周期间，iOS 和 Android 参与者的参与度和流失率存在显着差异。最后，治疗组之间的损耗率没有变化。本文还报告了可供进一步研究的大量数据，其中包括超过 300 万个旅行阶段和活动，分别标有交通方式和目的。
