Drabicki, Arkadiusz (author), Cats, O. (author), Kucharski, R.M. (author)Bus bunching is a well-known problem in public transport networks. It is characterized by a self-amplifying relationship between uneven distribution of rising passenger loads and deteriorating service regularity. The focus of this study is to analyse whether this negative feedback loop can be addressed by providing real-time crowding...conference paper 2021

Buijtenweg, Abel (author), Verma, T. (author), Cats, O. (author), Donners, Barth (author), Wang, H. (author)Public transport networks constitute critical infrastructure in urban systems. Public transport networks are characterised by their hierarchical structure, yet methods to quantify their underlying hierarchy are lacking. We propose a metric for quantifying the hierarchy in public transport networks which incorporates topological as well as...conference paper 2021

Coutinho, Felipe Mariz (author), van Oort, N. (author), Christoforou, Zoi (author), Alonso González, M.J. (author), Cats, O. (author), Hoogendoorn, S.P. (author)The diffusion of the smartphone and the urban sprawl is pushing both private and public actors to revisit the concept of the demand-responsive transit (DRT). Mokumflex is a DRT pilot program that replaced the regular bus service in low-density areas of Amsterdam, the Netherlands, for 12 months. The close collaboration with the private enterprise...conference paper 2020

Wang, Z. (author), Luo, D. (author), Cats, O. (author), Verma, T. (author)Hierarchy is regarded as a natural phenomenon of public transport networks (PTN). The imbalanced distribution of passenger flow result in a hierarchical structure of PTN and it is also related to the development of technology and the introduction of new modes. However, there is still a lack of knowledge on how to identify the hierarchical...conference paper 2020

Cats, O. (author), Krishnakumari, P.K. (author), Tundulyasaree, Krissada (author)In large-scale urban agglomerations, heavy rail in the form of metro and commuter train serves as the backbone of the metropolitan public transport network. Transport systems are subject to recurrent disruptions that may result in severe consequences for network performance and society at large. The objective of this paper is to compare the...conference paper 2019

(author)The impact of on-demand urban transport services on traffic reduction will depend on the willingness to share (WTS) of individuals. However, the extent to which individuals are willing to share remains largely unknown. By means of a stated preference experiment, this study analyses the WTS of respondents by comparing their preferences towards...conference paper 2019

Yap, M.D. (author), Cats, O. (author)Public transport disruptions can result in major impacts for passengers and operator. Our study objective is to predict disruption exposure at different stations, incorporating their location-specific characteristics. Based on a 13-month incident database for the Washington metro network, we successfully develop a supervised learning model to...conference paper 2019

Shelat, S. (author), Cats, O. (author), van Oort, N. (author), van Lint, J.W.C. (author)Identifying the set of alternatives from which travellers choose their routes is a crucial step in estimation and application of route choice models. These models are necessary for the prediction of network flows that are vital for the planning of public transport networks. However, choice set identification is typically difficult because...conference paper 2019

Imran, Aishah Mahyarni (author), van Oort, N. (author), Cats, O. (author), Hoogendoorn, S.P. (author), Van Der Pot, Pieter (author)Vehicle bunching often occurs in high-frequency transit systems leading to deterioration of service reliability. It is thus necessary to control vehicles during operations. Holding control is a common solution for this situation, but it may result in longer vehicle running times. Speed adjustments can contribute to more regular operations...conference paper 2019

Liu, T.L.K. (author), Krishnakumari, P.K. (author), Cats, O. (author)On-demand transport has become a common mode of transport with ride-sourcing companies like Uber, Lyft and Didi transforming the mobility market. Recurrent patterns in prevailing demand patterns can be used by service providers to better anticipate future demand distribution and thus support demand-Anticipatory fleet management strategies.

Narayan S., Jishnu (author), Cats, O. (author), van Oort, N. (author), Hoogendoorn, S.P. (author)The emergence of innovative mobility services, is changing the way people travel in urban areas. Such systems offer on-demand service (door-To-door or stop-To-stop, individual or shared) to passengers. In addition to providing flexible services to passengers, past studies suggested that such services could effectively absorb the demand for...conference paper 2019

This is especially true for self-driving vehicles deployed in public transport services. In this study, the relative preferences for a trip with a self-driving bus is assessed compared to a trip with a regular bus, based on...conference paper 2019
