Cats, O. (author)Urban bus services are subject to high levels of uncertainty and disturbances. Methods to determine the timetable are designed to absorb variations in riding times between stops by allocating additional travel time. The propagation of service unreliability along the route could be restrained by drivers' adjustment at stops and between stops....journal article 2019

Gkiotsalitis, K. (author), Wu, Z. (author), Cats, O. (author)Urban public transport operations in peak periods are characterized by highly uneven demand distributions and scarcity of resources. In this work, we propose a rule-based method for systematically generating and integrating alternative lining options, such as short-turning and interlining lines, into the frequency and resource allocation problem...journal article 2019

Soza Parra, J.A. (author), Cats, O. (author), Carney, Yvonne (author), Vanderwaart, Catherine (author)Headway management can potentially reduce passenger waiting time and on-board crowding on high-frequency services. In this study, a headway control experiment was conducted and evaluated for Washington Metropolitan Area Transit Agency routes 70 and 79 in Washington, D.C. The field experiment is evaluated by performing a before–after empirical...journal article 2019

Ashkrof, P. (author), Correia, Gonçalo (author), Cats, O. (author), van Arem, B. (author)Because of technology penetration in the transportation system, the automated vehicle (AV) is set to be a future mode of transport. Given the major implications of AVs, investigation of the potential impact of these vehicles on travel behavior is vital for a wide range of purposes, especially for policy making. In this study, we report the...journal article 2019

Luo, D. (author), Cats, O. (author), van Lint, J.W.C. (author)We present a pioneering investigation into the relation between passenger flow distribution and network properties in public transport systems. The methodology is designed in a reverse engineering fashion by utilizing passively measured passenger flow dynamics over the entire network. We quantify the properties of public transport networks using...journal article 2019

Cats, O. (author), Glück, Stefan (author)We integrate for the first time, to our knowledge, a dynamic transit assignment model into the tactical planning phase. The settings of service frequencies and vehicle capacities determine line capacity and have significant consequences for level-of-service and operational costs. The objective of this study is to determine frequency and vehicle...journal article 2019

van der Werff, Ellen (author), van Oort, N. (author), Cats, O. (author), Hoogendoorn, S.P. (author)Reliability is a key determinant of the quality of a transit service. Control is needed to deal with the stochastic nature of high-frequency bus services and to improve service reliability. This study focuses on holding control, both schedule- and headway-based strategies. An assessment framework is developed to systematically assess the effect...journal article 2019

Soza Parra, J.A. (author), Raveau, Sebastián (author), Muñoz, Juan Carlos (author), Cats, O. (author)Service reliability has an important impact on the satisfaction stated by public transport users with the service they receive. The main source of unreliability is found in headway variance, which also affects waiting times and distributes passengers unevenly across vehicles. However, it is still unclear how headway irregularity, with its impact...journal article 2019

Ton, D. (author), Zomer, L. (author), Schneider, F. (author), Hoogendoorn-Lanser, Sascha (author), Duives, D.C. (author), Cats, O. (author), Hoogendoorn, S.P. (author)Active modes (i.e. walking and cycling) have received significant attention by governments worldwide, due to the benefits related to the use of these modes. Consequently, governments are aiming for a modal shift from motorised to active modes. Attitudes are generally considered to play an important role in travel behaviour. Understanding the...journal article 2019

Abenoza, Roberto F. (author), Liu, Chengxi (author), Cats, O. (author), Susilo, Yusak O. (author)We examine the effect of weather, accessibility and built-environment characteristics on overall travel experience as well as the experience with the latest trips. These are factors that are often disregarded in the travel satisfaction literature even though they are believed to largely influence the first mile of the door-to-door trip. This...journal article 2019

Luo, D. (author), Cats, O. (author), van Lint, J.W.C. (author), Currie, Graham (author)Network science offers powerful concepts and methods for studying complex systems, such as public transport networks. However, many existing studies on complex network analysis of public transport networks were primarily motivated to test network science concepts using real-life networks. Consequently, important properties related to public...journal article 2019

(author)Background: Single-cell transcriptomics is rapidly advancing our understanding of the cellular composition of complex tissues and organisms. A major limitation in most analysis pipelines is the reliance on manual annotations to determine cell identities, which are time-consuming and irreproducible. The exponential growth in the number of...journal article 2019

Dixit, M. (author), Brands, T. (author), van Oort, N. (author), Cats, O. (author), Hoogendoorn, S.P. (author)Urban transit networks typically consist of multiple modes and the journeys may involve a transfer within or across modes. Therefore, the passenger experience of travel time reliability is based on the whole journey experience including the transfers. Although the impact of transfers on reliability has been highlighted in the literature, the...journal article 2019
