Krishnakumari, P.K. (author), Cats, O. (author), van Lint, J.W.C. (author)Graphs at different scales are essential tools for many transportation applications. Notwithstanding their relevance, these graphs are created and maintained manually for most applications, in both research and practice. In this paper, we develop a heuristic method for automatically generating multiscale graph representations without...journal article 2019

Ton, D. (author), Duives, D.C. (author), Cats, O. (author), Hoogendoorn, S.P. (author)Specifying the choice set for travel behaviour analysis is a non-trivial task. Its size and composition are known to influence the results of model estimation and prediction. Most studies specify the choice set using choice set generation algorithms. These methods can introduce two types of errors to the specified choice set: false negative ...journal article 2018

Malandri, Caterina (author), Fonzone, Achille (author), Cats, O. (author)We propose a method to evaluate public transport network vulnerability. We study the evolution of the passenger Volume Over Capacity (VOC) ratio throughout the network to measure the spatial and temporal extent of the impacts caused by an unplanned service segment disruption. The VOC ratio provides an indication of the on-board travel comfort...journal article 2018

Gavriilidou, A. (author), Cats, O. (author)Real-time holding control strategies are implemented, among other reasons, in order to protect transfers. In the context of high-frequency services, there is a need to reconcile between striving for single-line regularity and synchronizing inter-line arrivals. Their operationalization depends on the predictions regarding passenger flows...journal article 2018

Abenoza, Roberto F. (author), Ceccato, Vania (author), Susilo, Yusak O. (author), Cats, O. (author)Ensuring safety during door-to-door public transport trips is a fundamental challenge to service providers, as safety influences individuals’ mobility. Using reported safety perceptions of travelers waiting at six bus stops with different characteristics in Stockholm, this study investigates factors that have an impact on determining travelers’...journal article 2018

Ghaemi, N. (author), Cats, O. (author), Goverde, R.M.P. (author)In case of railway disruptions, traffic controllers are responsible for dealing with disrupted traffic and reduce the negative impact for the rest of the network. In case of a complete blockage when no train can use an entire track, a common practice is to short-turn trains. Trains approaching the blockage cannot proceed according to their...journal article 2018

Gkiotsalitis, K. (author), Cats, O. (author)Frequency setting requires the determination of the dispatching headways of all bus lines in a city network and constitutes the main activity in the tactical planning of public transport operations. Determining the dispatching headways of bus services in a city network is a multi-criteria problem that typically involves balancing between...journal article 2018

Abenoza, Roberto F. (author), Cats, O. (author), Susilo, Yusak O. (author)Understanding how satisfaction with individual trip legs aggregates to the overall travel experience for different types of trips will enable the identification of the trip legs that are most impactful. For this purpose we analyze data on retrospective evaluations of entire multi-modal trip experiences and satisfaction with individual trip...journal article 2018

Passenger Route Choice and Assignment Model for Combined Fixed and Flexible Public Transport SystemsNarayan S., Jishnu (author), Cats, O. (author), van Oort, N. (author), Hoogendoorn, S.P. (author)The recent technological innovations have given rise to innovative mobility solutions. Public transport systems combining such services need novel models for the design of services. We develop a multimodal route choice and assignment model for combined use of line/schedule based public transport systems (fixed public transport) and demand...conference paper 2018

Alonso González, M.J. (author), Hoogendoorn-Lanser, S. (author), van Oort, N. (author), Cats, O. (author), Hoogendoorn, S.P. (author)On-demand modes are playing an ever-increasing role in urban transportation. In<br/>particular, Demand Responsive Transit (DRT) (shared on-demand modes such as<br/>shared ride-hailing and microtransit) can complement scheduled public transport<br/>thanks to their collective nature. These services offer flexible and convenient<br/>mobility: they...conference paper 2018

Luo, D. (author), Cats, O. (author), van Lint, J.W.C. (author)It has been rarely investigated in the field of public transport whether passenger ow can be explained by network topology. Based on the rich data sets from The Hague, The Netherlands, we conduct this study try- ing to shed light upon this question. The relation between passenger ow and topological measures in different public transport network...conference paper 2018

Yap, M.D. (author), Luo, D. (author), Cats, O. (author)For large urban networks and hubs, optimizing transfer synchronization becomes computationally challenging. The objective of this paper is therefore to develop a generic, data-driven methodology to determine the key line/direction-combinations to synchronize based on passenger flows. We developed an approach to detect communities of directional...conference paper 2018

Cats, O. (author), van Beurden, Merlijn (author)This paper proposes a model for simultaneously determining the stopping patterns and frequencies of public transport services. Model formulation considers the impacts of alternative network design with limited stop solutions on passenger choice of origin and destination stations, route choice and possibly unsatisfied demand. The model is tested...conference paper 2018

Cats, O. (author), Glück, Stefan (author)This paper presents a model for frequency and vehicle capacity determination that uses a transit assignment model which can capture the dynamic effects on overall system performance. This allows accounting for variations in service reliability and crowding that have not been accounted for in the tactical planning insofar. Model formulation...conference paper 2018
