标题： The Mobilität.Leben Study: a Year-Long Mobility-Tracking Panel

摘要： Mobilität.Leben研究调查了德国一项自然实验对出行行为的影响。 为应对2022年的生活成本危机，2022年6月、7月和8月推出了两项政策措施，以降低民众的出行成本：汽油消费税减免和几乎免费的公共交通，即所谓的9欧元票。 宣布9欧元票的后续票种——所谓的德国票——导致立即决定继续这项研究。 Mobilität.Leben研究有两个阶段，即9欧元票阶段和德国票阶段，包括两个要素：多个问卷和基于智能手机的被动路径跟踪。 整个研究持续时间接近十三个月。 在本文中，我们报告了研究设计、招募策略、调查中的研究参与情况以及跟踪部分，并分享了进行这种大规模面板研究的经验。 总体而言，有3080人注册了我们的研究，其中1420人决定使用智能手机跟踪应用。 虽然两个阶段的相关问卷已由818名参与者完成，但我们有170名研究参与者在两个阶段都完成了跟踪和所有相关问卷。 我们发现，提供研究补偿可以提高参与效果。 可以得出结论，进行为期一年的面板研究是可行的，能够提供关于旅行者之间和内部出行行为异质性的丰富信息。 显示英文摘要

摘要： The Mobilit\"at.Leben study investigated travel behavior effects of a natural experiment in Germany. In response to the 2022 cost-of-living crisis, two policy measures to reduce travel costs for the population in June, July, and August 2022 were introduced: a fuel excise tax cut and almost fare-free public transport with the so-called 9-Euro-Ticket. The announcement of a successor ticket to the 9-Euro-Ticket, the so-called Deutschlandticket, led to the immediate decision to continue the study. The Mobilit\"at.Leben study has two periods, the 9-Euro-Ticket period and the Deutschlandticket period, and comprises two elements: several questionnaires and a smartphone-based passive waypoint tracking. The entire duration of the study was almost thirteen months. In this paper, we report on the study design, the recruitment strategy, the study participation in the survey, and the tracking parts, and we share our experience in conducting such large-scale panel studies. Overall, 3,080 people registered for our study of which 1,420 decided to use the smartphone tracking app. While the relevant questionnaires in both phases have been completed by 818 participants, we have 170 study participants who completed the tracking in both phases and all relevant questionnaires. We find that providing a study compensation increases participation performance. It can be concluded that conducting year-long panel studies is possible, providing rich information on the heterogeneity in travel behavior between and within travelers.
