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

Dubey, S.K. (author), Cats, O. (author), Hoogendoorn, S.P. (author)The potential lack of realism in stated-preference surveys is particularly acute in contexts where disaggregate real-world data is challenging to obtain. Mobility-on-Demand (MOD) services present one such context. The MOD context is unique due to factors such as service reliability (difference in stated vs. actual travel and waiting time) and...journal article 2024

Karatsoli, Maria (author), Nathanail, Eftihia (author), Basbas, Socrates (author), Cats, O. (author)The COVID-19 pandemic has impacted people's everyday lives, as avoiding being in crowded places became the number one societal rule. Crowdedness has therefore increasingly affected decisions such as a place visit via a specific path, the selection of a public transport stop, itinerary, etc., thereby making related information increasingly...journal article 2024

de Ruijter, A.J.F. (author), Cats, O. (author), van Lint, J.W.C. (author)Limited available market share data seems to suggest that ridesourcing platforms benefit from, even thrive on, socio-economic inequality. We suspect that this is associated with high levels of socio-economic inequality allowing for cheap labour as well as increasing the share of travellers with a considerably above-average willingness to pay...journal article 2024

Massobrio, R.M. (author), Cats, O. (author)Reducing the impact of disruptions is essential to provide reliable and attractive public transport. In this work, we introduce a topological approach for evaluating recoverability, i.e., the ability of public transport networks to return to their original performance level after disruptions, which we model as topological perturbations. We...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

Loudon, Eveline (author), Geržinič, N. (author), Molin, E.J.E. (author), Cats, O. (author)A plethora of shared fleet services have been introduced in cities worldwide. Despite their increased presence in urban areas, it is insofar unknown what are the main determinants of travellers’ choices between the usage of shared-mopeds and cars and thereby the extent to which shared moped can substitute car travel. To this end, we design and...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

Ashkrof, P. (author), Correia, Gonçalo (author), Cats, O. (author), van Arem, B. (author)Ride-sourcing drivers, as individual service suppliers, can freely adopt their own relocation strategies, including waiting, cruising freely, or following the platform recommendations. These decisions substantially impact the balance between supply and demand, and consequently affect system performance. We conducted a stated choice experiment...journal article 2023

Garrido Valenzuela, F.O. (author), Cats, O. (author), van Cranenburgh, S. (author)A thorough understanding of how urban space characteristics, such as urban equipment or network topology, affect people's density in urban spaces is essential to well-informed urban policy making. Hitherto, studies have primarily examined how the characteristics of the urban space impacts the number of people visiting different parts of the...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

Provoost, J.C. (author), Cats, O. (author), Hoogendoorn, S.P. (author)The ongoing research on tradable credit schemes (TCS) in mobility has captured the attention of policymakers, authorities and academics. Even though several studies have demonstrated the potential of such schemes, key policy design aspects that are relevant for real world implementation have been overlooked. There exists insofar no blueprint...journal article 2023

Grolle, J. (author), Donners, Barth (author), Annema, J.A. (author), Duinkerken, M.B. (author), Cats, O. (author)High-speed rail (HSR) is frequently seen as a promising alternative for long-distance travel by air and road, given its environmental advantages whilst offering a competitive level of service. However, a European HSR-network is yet to be realised, with the current state amounting to a patchwork of poorly connected subnetworks. Consequently,...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

Scerri, Karyn (author), Attard, Maria (author), Duives, D.C. (author), Cats, O. (author)Understanding people’s travel behavior is key to creating spaces that discourage car use, especially for short, walkable distances. The scope of this study is to understand better people’s propensity to use a car rather than walk for short-distance trips by focusing on the concept of perceived exertion (PE). A comparison is performed of two...journal article 2023

(author), Bogenberger, Klaus (author)The interest in tradable mobility credits (TMC) is growing steadily. Compared to existing instruments, its cap-and-trade design for the demand side ensures that a limited quantity, e.g., traffic and related emissions, can by design not be exceeded. However, most TMC schemes are market-based financial instruments that can only be successful,...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

(author)Understanding user's perception of service variability is essential to discern their overall perception of any type of (transport) service. We study the perception of waiting time variability for ride-hailing services. We carried out a stated preference survey in August 2021, yielding 936 valid responses. The respondents were faced with...journal article 2023
