Abstract:A better understanding of mobility behaviors is relevant to many applications in public transportation, from more accurate travel demand models to improved supply adjustment, customized services and integrated pricing. In line with this context, this study mined 51 weeks of smart card (SC) data from Montréal, Canada to analyze interpersonal and intrapersonal variability in the weekly use of public transit. Passengers who used only one type of product (AP − annual pass, MP − monthly pass, or TB − ticket book) o… Show more
“…As regard the first meaning—the sharing of data and information—some studies describe the creation of collaborative mobility systems that allow vehicles and infrastructures to interconnect and share information to coordinate their actions (Autili et al 2019). Especially in large cities, the use of smart cards makes it possible to analyze interpersonal and intrapersonal variability in the weekly use of public transit (Deschaintres, Morency, and Trépanier 2019), therefore to infer the mobility models of urban collective transport services (Zhao et al 2019) and plan more efficient services that are close to citizens’ needs. Supporting mobility through automation processes can make the transport system so efficient as to manage traffic flows and adapt in real time by eliminating or minimizing total movements.…”
This work aims to reorganize theoretical and empirical research on smart mobility through the systematic literature review approach. The research goal is to reach an extended and shared definition of smart mobility using the cluster analysis. The article provides a summary of the state of the art that can have broader impacts in determining new angles for approaching research. In particular, the results will be a reference for future quantitative developments for the authors who are working on the construction of a territorial measurement model of the smartness degree, helping them in identifying performance indicators consistent with the definition proposed.

“…Several studies have used k-means clustering or hierarchical clustering methods to Chapter 4. Methods for Processing Large-Scale Passive Data group passengers by their temporal patterns (Viallard et al, 2019;Deschaintres et al, 2019;Egu and Bonnel, 2020). Some authors also include spatial patterns such as the regular use of the same route to group passengers (Manley et al, 2018;Morency et al, 2007).…”

“…It is also possible to use clustering (see Chapter 4.2) to automatically identify groups for aggregation. An example is identifying different groups of travellers by their travel behaviour (Deschaintres et al, 2019). An essential tool to understand and draw conclusions from the data is visualisation.…”

First, I would like to thank my main supervisor Clas Rydergren and my co-supervisor David Gundlegård. I very much appreciate that you have always been available and gave me guidance and inspiration. Thank you for sharing your knowledge in lengthy discussions and taking the time to give feedback that challenged me to continuously improve. I very much enjoyed working together with you! I would also like to thank Lars Sköld, Simon Moritz, Ida Kristofferson and Di Yuan, and all others who made this work possible with their engagement.The research in this thesis has been to a large extend funded by the projects Mobile Network Origin Destination Estimation (MODE) and Mobile Network Data in Future Transport Systems (MOFT), both financed by Vinnova and Demand model estimation based on combination of active and passive data collection (DEMOPAN) funded by Trafikverket.I also want to thank all my colleagues at the division of Communication and Transportation Systems (KTS). I really appreciated being part of a group this international, with different research fields and perspectives. The last year of working from home made it clear how much I miss the interaction and informal discussion with you! In particular, I want to thank the group of PhD students for the great company, fun times and all mutual support. Special thanks go to Niki and Mats for their commitment to represent the PhD students at KTS! A big thank also to Morten Eltved, Jesper Bláfoss Ingvardson and Otto Anker Nielsen at DTU in Copenhagen. I really enjoyed working with you, even though my research visit turned out to be two and a half only weeks instead of three months, due to the pandemic. Yet, two fredagsøl were enough to start appreciating the Danish culture.Finally, I would like to thank all my friends, my sister Annalena and my dear parents Marita and Gerd-Herbert, for their unconditional support. Thank you, Fanny, for all your love and for reminding me that there are other things in life than research.
“…Tao et al (2014) compared origins and destinations distribution over the time to discover patterns for different social groups of passengers. Similar to studies on boarding information, origin and destination pairs were recently used for passenger and weeks clustering (Deschaintres et al 2019;He et al 2020).…”
Sustainable urban mobility remains an emerging research topic during last decades. In recent years, the smart card data collection systems have become widespread and many studies have been focused on usage of anonymized data from these systems for better understanding of mobility patterns of Public Transport (PT) passengers. Data-driven mobility patterns can benefit transport planners at strategic, tactical, and operational levels. A particular point of interest is a spatiotemporal dynamics of mobility patterns that highlights transformation of the PT passenger flows over the time continuously or in response to modifications of the PT system and policies. This study is aimed to estimation and analysis of the spatiotemporal dynamics of PT passenger flows in Riga (Latvia). A multi-stage methodology was proposed and includes three main stages: (1) estimation of individual trip vectors, (2) clustering of trip vectors into spatiotemporal mobility patterns, and (3) further analysis of mobility patterns’ dynamics. The best practice methods are applied at every stage of the proposed methodology: the smart card validation flow is used for extracting information on boarding locations; the trip chain approach is used for estimation of individual trip destinations; vector-based clustering algorithms are utilised for identification of mobility patterns and discovering their dynamics. The resulting methodology provides an advanced tool for observing and managing of PT demand fluctuation on a daily basis. The methodology was applied for mining of a large smart card data set (124 million records) for year 2018. Most important empirical results include obtained daily mobility patterns in Riga, their clusters, and within-cluster dynamics over the year. Obtained daily mobility patterns allows estimation of a city-level PT origin–destination matrix that is useful in many applied areas, e.g., dynamic passenger flow assignment models. Mobility pattern-based clustering of days allows effective comparison and flexible tuning of the PT system for different days of a week, public holidays, extreme weather conditions, and large events. Dynamics of mobility patterns allows estimating the effect of implementing changes (e.g., fare increase or road maintenance) and demand forecasting for user-focused development of PT system.
