Cats, O. (author), Reimal, T. (author), Susilo, Y. (author)Cities worldwide are looking for new policies to attract travelers to shift from cars to public transport. Policies focused on reducing public transport fares are aimed at improving social inclusion and leading to a modal shift. The City of Tallinn, the capital of Estonia, has recently introduced a fare-free public transport (FFPT) service in an...journal article 2014

Hlotova, Y. (author), Cats, O. (author), Meijer, S.A. (author)Stress is an immense problem in modern society; approximately half of all occupational illnesses are directly or indirectly related to stress. The work of a bus driver is typically associated with high stress levels that negatively influence individual well-being as well as workforce management. The current study examined the impact of newly...journal article 2014

Cats, O. (author)Traditionally, transport systems have been designed to perform well under normal conditions assuming that everything works as planned. As anyone that uses public transport can testify, deviations from planning are a recurrent phenomenon. Investments in public transport are therefore increasingly motivated by the need to improve their reliability...journal article 2015

Morriea-Matias, Luis (author), Cats, O. (author)The rapid increase in automated data collection in the public transport industry facilitates the adjustment of operational planning and real-time operations based on the prevailing traffic and demand conditions. In contrast to automated passenger counts systems, automated vehicle location (AVL) data are often available for the entire public...journal article 2016

Cats, O. (author), Susilo, YO (author), Reimal, T (author)The subsidy level of public transport systems varies considerably among systems worldwide. While limited-scale free-fare public transport (FFPT) services such as limited campaigns and fare evasion for special groups or specific services are prevalent, there is only limited evidence on the consequences of introducing a full-fledged FFPT. The case...journal article 2016

Fadaei, Masoud (author), Cats, O. (author)Design and operational measures are designed and implemented to improve public transport performance and level-of-service. In the case of urban bus systems, priority, operational and control measures are aimed to elevate bus services to buses with high level of service (BHLS). Even though there is an explosive growth in design and operational...journal article 2016

Papacharalampous, A.E. (author), Cats, O. (author), Lankhaar, Jan-Willem (author), Daamen, W. (author), van Lint, J.W.C. (author)Many of the transportation problems prevalent in urban areas culminate in large-scale events. Such events generate large multimodal flows that arrive and depart within short time intervals to constrained areas. Monitoring and managing big events pose a challenge for transport planners, operators, event organizers, and city officials. In this...journal article 2016

Morriea-Matias, Luis (author), Cats, O. (author), Gama, Joao (author), Mendes-Moreira, Joao (author), Freire de Sousa, Jorge (author)Recent advances in telecommunications created new opportunities for monitoring public transport operations in real-time. This paper presents an automatic control framework to mitigate the Bus Bunching phenomenon in real-time. The framework depicts a powerful combination of distinct Machine Learning principles and methods to extract valuable...journal article 2016

Cats, O. (author), Loutos, G (author)Online predictions of bus arrival times have the potential to reduce the uncertainty associated with bus operations. By better anticipating future conditions, online predictions can reduce perceived and actual passenger travel times as well as facilitate more proactive decision making by service providers. Even though considerable research...journal article 2016

Cats, O. (author), Hartl, Maximilian (author)Transit systems are subject to congestion that influences system performance and level of service. The evaluation of measures to relieve congestion requires models that can capture their network effects and passengers' adaptation. In particular, on-board congestion leads to an increase of crowding discomfort and denied boarding and a decrease in...journal article 2016

Cats, O. (author)Investments in transport are increasingly motivated by the need to improve its robustness — the capacity to absorb disturbances with a minimal impact on system performance. Nonetheless, there is lack of knowledge on how to assess and quantify the robustness value of new investments. This study investigates the robustness of alternative public...journal article 2016

Fadaei, Masoud (author), Cats, O. (author), Bhaskar, Ashish (author)The uncertainty associated with public transport services can be partially counteracted by developing real-time models to predict downstream service conditions. In this study, a hybrid approach for predicting bus trajectories by integrating multiple predictors is proposed. The prediction model combines schedule, instantaneous and historical...journal article 2016

Cats, O. (author), Koppenol, Gert Jaap (author), Warnier, Martijn (author)Network robustness refers to as the capacity to absorb disturbances with a minimal impact on system performance. Notwithstanding, network robustness assessment has been mostly confined to the analysis of complete link breakdown based on topological metrics. We propose reliability indicators that encompass changes in network performance with...journal article 2017

Cats, O. (author), Jenelius, E (author)Disruptions in public transport networks (PTNs) often lead to partial capacity reductions rather than complete closures. This study aims to move beyond the vulnerability analysis of complete failures by investigating the impacts of a range of capacity reductions on PTN performance. The relation between network performance and the degradation of...journal article 2017

Abenoza, RF (author), Cats, O.

This study identifies and characterizes current and potential users of public transport in Sweden and identifies the most important...journal article 2017

Molin, E.J.E. (author), Blangé, J. (author), Cats, O. (author), Chorus, C.G. (author)The risk of being involved in an airplane accident is largely ignored in air passengers’ choice models. The reason presumably is that it is hard to operationalize, because objective safety indicators often involve extremely low probabilities that are hard to grasp and interpret by passengers. In this paper, we propose an operationalization...journal article 2017

West, J (author), Cats, O. (author)Assessment of transit service improvements such as bus lanes, allowing boarding through all doors, and headway-based holding control requires detailed simulation capabilities. However, because the usage of models advanced enough to simultaneously analyze physical and operational measures has been limited, their validity has hitherto remained low...journal article 2017

Ghaemi, N. (author), Cats, O. (author), Goverde, R.M.P. (author)Currently railway traffic controllers use predefined solutions (contingency plans) to deal with a disruption. These plans are manually designed by expert traffic controllers and are specific to a certain location and timetable. With a slight change in the timetable or infrastructure, these plans might not be feasible and have to be updated....journal article 2017

Luo, D. (author), Cats, O. (author), van Lint, J.W.C. (author)So-called tap-in–tap-off smart card data have become increasingly available and popular as a result of the deployment of automatic fare collection systems on transit systems in many cities and areas worldwide. An opportunity to obtain much more accurate transit demand data than before has thus been opened to both researchers and practitioners....journal article 2017
