Luo, D. (author), Cats, O. (author), van Lint, J.W.C. (author)Transit networks are complex systems in which the passenger flow dynamics are difficult to capture and understand. While there is a growing ability to monitor and record travelers' behavior in the past decade, knowledge on network-wide passenger flows, which are essentially high-dimensional multivariate data, is still limited. This paper...conference paper 2017

van der Vliet, J.P. (author), Pel, A.J. (author), van Lint, J.W.C. (author)Current procedure in travel demand estimation models is to separately deal with attraction, production and trip distribution, where the latter typically assumes inverse distance proportionality. We show that this procedure leads to errors in the demand estimation, particularly when dealing with very specific zones and heterogeneous travel...conference paper 2017

Brand, Judith (author), Hoogendoorn, S.P. (author), van Oort, N. (author), Schalkwijk, Bart (author)Demand for (public) transportation is subject to dynamics affected by technological, spatial, societal and demographic aspects. The political environment, together with financial and spatial constraints limit the possibilities to address transit issues arising from growing demand through the construction of new infrastructure. Upgrading of...conference paper 2017

Yan, F. (author), Goverde, R.M.P. (author)This paper focuses on optimizing the robustness of a timetable with multiple train lines of different frequencies, where overtakings are also taken into account. An optimization model is considered of a cyclic railway timetable problem where dwell times and running times are variable and overtaking is allowed for relevant stations and each...conference paper 2017

Localised estimation and control of linear instabilities in two-dimensional wall-bounded shear flowsTol, H.J. (author), Kotsonis, M. (author), de Visser, C.C. (author), Bamieh, B. (author)A new framework is presented for estimation and control of instabilities in wall-bounded shear flows described by the linearised Navier-Stokes equations. The control design considers the use of localised actuators/sensors to account for convective instabilities in an optimal control framework. External sources of disturbances are assumed to...journal article 2017

Wani, Omar (author), Beckers, Joost V.L. (author), Weerts, Albrecht H. (author), Solomatine, D.P. (author)A non-parametric method is applied to quantify residual uncertainty in hydrologic streamflow forecasting. This method acts as a post-processor on deterministic model forecasts and generates a residual uncertainty distribution. Based on instance-based learning, it uses a k nearest-neighbour search for similar historical hydrometeorological...journal article 2017
