Leffler, David (author), Burghout, Wilco (author), Cats, O. (author), Jenelius, Erik (author)Over the past decade, there has been a surge of interest in the application of agent-based simulation models to evaluate flexible transit solutions characterized by different degrees of short-term flexibility in routing and scheduling. A central modelling decision in the development is how one chooses to represent the mode- and route-choices...journal article 2024

Yap, M.D. (author), Wong, Howard (author), Cats, O. (author)Understanding how passengers perceive public transport interchanges is important to better explain current public transport mode and route choice behaviour and to better predict future demand levels. In this study we derive how passengers value a public transport interchange in a metropolitan context entirely based on recent, large-scale,...journal article 2024

Liu, Tao (author), Ji, Wen (author), Gkiotsalitis, Konstantinos (author), Cats, O. (author)Transfer optimization in public transport (PT) networks can be achieved through coordinated timetabling and vehicle scheduling. Traditionally, the coordinated timetabling problem is solved first before proceeding to the vehicle scheduling problem. The integration of these two problems can help further reduce the total operation cost and...journal article 2023

Wang, Z. (author), Huang, Ketong (author), Massobrio, R.M. (author), Bombelli, A. (author), Cats, O. (author)Network hierarchy describes the relative arrangement of network elements and reflects its fundamental structure. We propose a multi-dimensional topology-based method for quantifying and comparing the extent to which different Public Transport Networks (PTNs) exhibit a hierarchical structure. The proposed method considers the uneven distribution...journal article 2023

Drabicki, Arkadiusz (author), Cats, O. (author), Kucharski, R.M. (author), Fonzone, Achille (author), Szarata, Andrzej (author)Overcrowding is a major phenomenon affecting travel experience in urban public transport, whose negative impacts can be potentially mitigated with real-time crowding information (RTCI) on public transport vehicle departures. In this study, we investigate the willingness to wait (WTW) with instantaneous RTCI to avoid the in-vehicle (over...journal article 2023

Hatzenbühler, Jonas (author), Jenelius, Erik (author), Gidófalvi, Gyözö (author), Cats, O. (author)This study investigates the potential of modular vehicle concepts and consolidation to increase the efficiency of urban freight and passenger transport. Modularity is achieved by connecting multiple vehicles together to form a platoon. Consolidation is realized by integrating passenger and freight demand in the routing problem. Vehicles are...journal article 2023

Peftitsi, Soumela (author), Jenelius, Erik (author), Cats, O. (author)Increasing the operating speed in public transport systems can increase the system capacity, reduce the overall passenger travel time and improve experienced comfort. Skip-stop operation, where subsets of the trains operating on the same tracks skip certain intermediate stops, can accelerate the service and improve passengers’ overall travel...journal article 2023

Dixit, M. (author), Cats, O. (author), van Oort, N. (author), Brands, T. (author), Hoogendoorn, S.P. (author)Validation of travel demand models, although recognised as important, is seldom undertaken. This study adds to the scarce literature in this field by undertaking an external validation of a multi-modal transit route choice model. The model was estimated using smart card data for the urban transit network of Amsterdam before the introduction...journal article 2023

Kolkowski, L. (author), Cats, O. (author), Dixit, M. (author), Verma, T. (author), Jenelius, Erik (author), Cebecauer, Matej (author), Rubensson, Isak Jarlebring (author)While social segregation is often assessed using static data concerning residential areas, the extent to which people with diverse background travel to the same destinations may offer an additional perspective on the extent of urban segregation. This study further contributes to the measurement of activity-based social segregation between...journal article 2023

Wilkesmann, Florian (author), Ton, Danique (author), Schakenbos, Rik (author), Cats, O. (author)First and last mile connectivity of public transport hubs is a key component in promoting multi-modal travel. The Dutch train station operator (NS Stations) promotes the combination of bike and train by offering a train station-based round-trip bikesharing (SBRT) scheme, known as ‘OV-fiets’, located at train stations throughout the country....journal article 2023

Liu, B. (author), Ji, Yuxiong (author), Cats, O. (author)Public transport (PT) agencies are increasingly keen on integrating ride-hailing (RH) services with PT to improve overall mobility. Understanding the traffic flow distribution in the integrated system is vital for the policy decision-making and services design of such a system. We propose a stochastic user equilibrium (SUE) model for...journal article 2023

Yap, M.D. (author), Wong, Howard (author), Cats, O. (author)It is important to understand how public transport passengers value on-board crowding since the outbreak of the COVID-19 pandemic. The main contribution of this study is to derive the crowding valuation of public transport passengers in a post-pandemic era entirely based on observed, actual passenger route choices. We derive passengers’...journal article 2023

Cats, O. (author)Human mobility is subject to collective dynamics that are the outcome of numerous individual choices. Smart card data which originated as a means of facilitating automated fare collection has emerged as an invaluable source for analysing mobility patterns. A variety of clustering and segmentation techniques has been adopted and adapted for...journal article 2023

Gkiotsalitis, Konstantinos (author), Cats, O. (author), Liu, T. (author)We perform a systematic review of real-time control strategies for transfer synchronisations in public transport. In particular, we review inter-station and intra-station control measures that can be applied in near real-time, including vehicle holding, stop-skipping, speed control, short-turning, rescheduling, interlining, rerouting, and...journal article 2022

Cats, O. (author), Ferranti, Francesco (author)Urban and regional areas worldwide exhibit a complex and uneven distribution of activities with certain areas attracting more people during different time periods. In this study we systemically classify different parts of the urban area which are most attractive as measured by their ability to attract visitors. A weekly visiting profile is...journal article 2022

Shelat, S. (author), Cats, O. (author), van Cranenburgh, S. (author)With a few exceptions, public transport ridership around the world has been hit hard by the COVID-19 pandemic. Travellers are now likely to adapt their behaviour with a focus on factors that contribute to the risk of COVID-19 transmission. Given the unprecedented spatial and temporal scale of this crisis, these changes in behaviour may even...journal article 2022

Cats, O. (author), Ferranti, Francesco (author)The increasing availability of longitudinal individual human mobility traces enables the disaggregate analysis of temporal properties of mobility patterns. The objective of this study is to identify distinctive market segments in terms of habitual temporal travel patterns of public transport users. First, travel patterns are clustered using a...journal article 2022

Yap, M.D. (author), Cats, O. (author)Urban metro and tram networks are regularly subject to planned disruptions, including closures, resulting from the need to maintain and renew infrastructure. In this study, we first empirically analyse the passenger demand response to planned public transport disruptions based on individual passenger travel behaviour, based on which we infer...journal article 2022

Shelat, S. (author), Cats, O. (author), van Oort, N. (author), van Lint, J.W.C. (author)Unreliable waiting times may cause frustration and anxiety amongst public transport travellers. Although the effect of travel time reliability has been studied extensively, most studies have used stated preferences which have disadvantages, such as an inherent hypothetical bias, or have analysed revealed preferences for road traffic. Here, we...journal article 2022

Yap, M.D. (author), Cats, O. (author), Törnquist Krasemann, Johanna (author), van Oort, N. (author), Hoogendoorn, S.P. (author)Due to the multi-level nature of public transport networks, disruption impacts may spill-over beyond the primary effects occurring at the disrupted network level. During a public transport disruption, it is therefore important to quantify and control the disruption impacts for the total public transport network, instead of delimiting the...journal article 2022
