Wierbos, M.J. (author)This dissertation studies the dynamics of bicycle traffic flow. The research focuses on busy situations such as bicycle queues at intersections and congestion upstream of a bottleneck. The cycling movements are analyzed on the aggregated scale in terms of density, speed and flow. Furthermore, cyclists are included in a traffic flow model by...doctoral thesis 2021

Abbas, Omar (author)Placing wind turbines together is economically advantageous. It helps in decreasing the use of land or sea space, impact on the landscape and the cost of installation and maintenance. However, placing turbines together has a downside: the aerodynamics interaction caused by the wakes can negatively influence the total electrical power production...master thesis 2021

YUS SANTANA, Monica (author)At present, the energy transition is increasingly being driven by the integration of renewable energy into the grid. However, this weather-dependent energy generation imposes challenges to the system operators since the deviations between the forecasted and the actual generation keep increasing due to this intermittent generation. Moreover, new...master thesis 2021

de Groot, Frans (author)Although e-groceries is nothing new, the scale at which it is currently growing in the Netherlands has not been seen before. Over the past four years, the market share of online grocery shopping showed an average growth of over 20% per year. While it was already challenging to keep up with this high demand, it became increasingly more difficult...master thesis 2021

(author)Cooperative intelligent transportation systems (C-ITS) support the exchange of information between vehicles and infrastructure (V2I or I2V). This paper presents an in-vehicle C-ITS application to improve traffic efficiency around a merging section. The application balances the distribution of traffic over the available lanes of a freeway, by...journal article 2021

Yildiz, B. (author), Uijttewaal, W.S.J. (author), Bricker, J.D. (author), Mosselman, E. (author)Weirs are flow control structures that can be used for flow diversion purposes. They are classified according to section geometry or their length in the flow direction. For sharp-crested rectangular weirs, Rehbock [1] derived stage-discharge equations. In contracted geometries, streamlines curve at the approach flow leading to variations in flow...conference paper 2021

Raju, Narayana (author), Arkatkar, Shriniwas (author), Easa, Said (author), Joshi, Gaurang (author)This study aims to model traffic flow under weak lane based heterogonous (mixed) traffic conditions. Unlike homogeneous traffic, when a follower (subject) vehicle in mixed traffic moves closer to its leader vehicle, it tends to adjust its longitudinal movement or change its lane and acts discretely. Due to this phenomenon, traffic flow modeling...journal article 2021

Natural Fracture Network Characterisation: Numerical modelling, outcrop analysis and subsurface dataBoersma, Q.D. (author)Responsibly using the subsurface for geo-energy extraction or storage requires an accurate understanding of the static and dynamic behaviour of the targeted reservoirs. While mostly dependent on intrinsic rock properties (e.g. porosity and permeability), this behaviour is also believed to be significantly impacted by the presence of natural...doctoral thesis 2020

van der Zaag, Jochem (author)To allow society to operate within planetary boundaries, it is essential to reduce primary material consumption. The Dutch government has set goals to limit the primary extraction by half in 2030 and to be a fully circular economy by 2050. To be able to achieve this without reducing our standards of living, the only way is to extract the...master thesis 2020

Meulenbroek, B.J. (author), Farajzadeh, R. (author), Bruining, J. (author)Recently, there is an increased interest in reactive flow in porous media, in groundwater, agricultural and fuel recovery applications. Reactive flow modeling involves vastly different reaction rates, i.e., differing by many orders of magnitude. Solving the ensuing model equations can be computationally intensive. Categorizing reactions...journal article 2020

Zhao, J. (author), Knoop, V.L. (author), Wang, Z. (author)Modeling traffic flow at intersections is essential for the design, control, and management of intersections. A challenging feature of microscopic modeling vehicular movement at intersections is that drivers can choose among an infinite number of alternative traveling paths and speeds. This makes it fundamentally different from structured...journal article 2020

Wierbos, M.J. (author), Knoop, V.L. (author), Hanseler, F.S. (author), Hoogendoorn, S.P. (author)Bicycles are gaining popularity as a mode of transport resulting in a mixed bicycle–car traffic situation on urban roads. Cyclists however, are hardly included in traffic flow models which complicates the design of safe and congestion-free traffic situations. This work introduces class-specific speed functions based on two variables, being space...journal article 2020

Sun, Junzi (author), Hoekstra, J.M. (author), Ellerbroek, Joost (author)Air traffic simulations serve as common practice to evaluate different concepts and methods for air transportation studies. The aircraft performance model is a key element that supports these simulation-based studies. It is also an important component for simulation-independent studies, such as air traffic optimization and prediction studies....journal article 2020
