Drabicki, Arkadiusz (author), Kucharski, Rafał (author), Cats, O. (author)A common problem in public transport systems is bus bunching, characterized by a negative feedback loop between service headways, number of boarding passengers and dwell times. In this study, we examine whether providing real-time crowding information (RTCI) at the stop regarding the two next vehicle departures can stimulate passengers to...journal article 2022

Geržinič, N. (author), van Oort, N. (author), Hoogendoorn-Lanser, S. (author), Cats, O. (author), Hoogendoorn, S.P. (author)On-demand mobility services are promising to revolutionise urban travel, but preliminary studies are showing they may actually increase total vehicle miles travelled, worsening road congestion in cities. In this study, we assess the demand for on-demand mobility services in urban areas, using a stated preference survey, to understand the...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

Cats, O. (author), Pudane, B. (author), van der Poel, Johanan (author), Kroesen, M. (author)Academics are often environmentally-minded, and they often travel internationally to share their research. Are they prone to attitude-behaviour gap? We collected data from 104 academics in Europe regarding attitudes towards online conferences, flight shame and carbon offsetting, and analysed their trip-making and mode choices in hypothetical...journal article 2022

Dubey, S.K. (author), Cats, O. (author), Hoogendoorn, S.P. (author), Bansal, Prateek (author)Several non-linear functions and machine learning methods have been developed for flexible specification of the systematic utility in discrete choice models. However, they lack interpretability, do not ensure monotonicity conditions, and restrict substitution patterns. We address the first two challenges by modeling the systematic utility...journal article 2022

Soza Parra, J.A. (author), Kucharski, Rafal (author), Cats, O. (author)In In this study, we set out to explore how various spatial patterns of travel demand drive the effectiveness of ride-pooling services. To do so, we generate a broad range of synthetic, yet plausible demand patterns. We experiment with the number of attraction centres, the dispersion of destinations around these centres, and the trip length...journal article 2022

Fielbaum, Andres (author), Kucharski, R.M. (author), Cats, O. (author), Alonso-Mora, J. (author)Emerging on-demand sharing alternatives, in which one resource is utilised simultaneously by a circumstantial group of users, entail several challenges regarding how to coordinate such users. A very relevant case refers to how to form groups in a mobility system that offers shared rides, and how to split the costs within the travellers of a...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

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

Ashkrof, P. (author), Correia, Gonçalo (author), Cats, O. (author), van Arem, B. (author)The performance of ride-sourcing services such as Uber and Lyft is determined by the collective choices of individual drivers who are not only chauffeurs but private fleet providers. In such a context, ride-sourcing drivers are free to decide whether to accept or decline ride requests assigned by the ride-hailing platform. Drivers’ ride...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), Kucharski, R.M. (author), Danda, Santosh Rao (author), Yap, M.D. (author)Since ride-hailing has become an important travel alternative in many cities worldwide, a fervent debate is underway on whether it competes with or complements public transport services. We use Uber trip data in six cities in the United States and Europe to identify the most attractive public transport alternative for each ride. We then...journal article 2022

de Ruijter, A.J.F. (author), Cats, O. (author), Kucharski, R.M. (author), van Lint, J.W.C. (author)Contrary to traditional transit services, supply in ridesourcing systems emerges from individual labour decisions of gig workers. The effect of decentralisation in supply on the evolution of on-demand transit services is largely unknown. To this end, we propose a dynamic model comprising of the subsequent supply-side processes: (i) initial...journal article 2022

Dubey, S.K. (author), Sharma, Ishant (author), Mishra, Sabyasachee (author), Cats, O. (author), Bansal, Prateek (author)Due to the unavailability of prototypes, the early adopters of novel products actively seek information from multiple sources (e.g., media and social networks) to minimize the potential risk. The existing behavior models not only fail to capture the information propagation within the individual's social network, but also they do not...journal article 2022

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

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

Gadepalli, Ravi (author), Gumireddy, Sushmitha (author), Bhamidipati, Srirama (author), Cats, O. (author)Many cities have introduced metro rail systems over the past two decades, particularly in developing countries. However, there is lack of knowledge on the impacts of new lines on the service and ridership for the related urban bus lines, and in particular those directly affected by the opening of the new service(s). We undertake a...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

Gkiotsalitis, K. (author), Cats, O. (author)In this literature review, we systematically review studies on public transit control with a specific focus on at-stop measures. In our synthesis of the relevant literature, we consider three perspectives: (1) the mathematical models of the proposed methodologies; (2) their complexity; (3) their applicability in real-time operations and their...journal article 2021

Kucharski, R.M. (author), Cats, O. (author), Sienkiewicz, Julian (author)Urban mobility needs alternative sustainable travel modes to keep our pandemic cities in motion. Ride-pooling, where a single vehicle is shared by more than one traveller, is not only appealing for mobility platforms and their travellers, but also for promoting the sustainability of urban mobility systems. Yet, the potential of ride-pooling...journal article 2021
