Yuan, K. (author), Knoop, V.L. (author), Zwaal, B.A. (author), van Lint, J.W.C. (author)With the renewed interest in the Macroscopic Fundamental Diagram (MFD) in the last decade, studies on network-level urban traffic control have increased in popularity. A popular urban traffic control approach is perimeter control, in which vehicle accumulation is kept below some critical accumulation value. An alternative control strategy is to...conference paper 2020

de Graaf, Lara (author)This graduation project focuses on balancing entertainment and social value of football to create relatedness and belonging among the younger supporters in Arnhem and Vitesse. Relatedness and belonging are two of the thirteen fundamental needs defined by Desmet and Fokkinga (2018). Designing for fundamental needs is one of the eight approaches...master thesis 2019

Sloot, Mark (author)The aim of this master thesis is to develop a dynamic zone-based traffic model for large areas, using the concept of the Network Fundamental Diagram (NFD), which relates the average internal flow (production) and speed in a zone to the number of vehicles in the same zone (accumulation). The model that has been developed is then applied to the...master thesis 2019

Snelder, M. (author), Wilmink, Isabel (author), van der Gun, J.P.T. (author), Bergveld, Hendrik Jan (author), Hoseini, Parvin (author), van Arem, B. (author)This paper presents a model specifically developed to explore the mobility impacts of connected and automated driving and shared mobility. It is an explorative iterative model that uses an elasticity model for destination choice, a multinomial logit model for mode choice and a network fundamental diagram to assess traffic impacts. To the best...conference paper 2019

Knoop, V.L. (author), van Erp, P.B.C. (author), Leclercq, Ludovic (author), Hoogendoorn, S.P. (author)<br/>The Macroscopic Fundamental Diagram (MFD) describes the relation between accumulation and speed in a zone. While theoretically expected, empirical validations have been done with limited numbers of floating car (e.g., taxi) data, and loop detectors. This paper will verify existence, shape and crispness of the MFD using Floating Car Data ...conference paper 2019

Keyvan-Ekbatania, Mehdi (author), Gaob, Xueyu (Shirley) (author), Gayahb, Vikash V. (author), Knoop, V.L. (author)Empirical and research evidence suggests that traffic-responsive signal control strategies are generally not as efficient in over-saturated traffic conditions characterized by queue spillbacks. Recent studies on (MFD/NFD) have identified a destabilizing gridlock process that arises in congested networks which precludes efficient operation. The...journal article 2019

Yuan, K. (author), Knoop, V.L. (author), Hoogendoorn, S.P. (author)Scarce urban space makes urban streets have to be partly shared by cars and cyclists. Traffic flow can be considerably influenced by cyclists, which are comparatively slower than cars. The fundamental diagram (FD) can change greatly, correlating to bike lane length and the cyclist flow. Models for the traffic dynamics on the space-shared streets...journal article 2019

Yu, Chak Shun (author)Developers spend the majority of their time and effort on reading and comprehending source code. In order to improve this process of program comprehension for developers, a numerous amount of existing studies have looked into understanding how developers approach it and factors of influence. However, less is known in the field about how...master thesis 2018

van der Gun, J.P.T. (author), Pel, A.J. (author), van Arem, B. (author)The link transmission model is a macroscopic network traffic flow simulation tool based on Lighthill–Whitham–Richards theory. While its efficiency and accuracy are superior to the well-known cell transmission model, applications of its current numerical formulations are limited by the inability to apply changes to the fundamental diagrams of...journal article 2018

Versteijlen, W.G. (author)Offshore wind generated electricity is currently one of the most promising sources of energy to contribute in creating a sustainable global energy mix. The latter is essential for minimising the detrimental impact of human-induced accelerated climate change. The cost of offshore wind power has strongly decreased over the past years due to ...doctoral thesis 2018

Ji, Yangbeibei (author), Xu, Mingwei (author), Li, Jie (author), van Zuylen, H.J. (author)The macroscopic fundamental diagram (MFD) is a graphical method used to characterize the traffic state in a road network and to monitor and evaluate the effect of traffic management. For the determination of an MFD, both traffic volumes and traffic densities are needed. This study introduces a methodology to determine an MFD using combined...journal article 2018

(author)Long-term emissions of Municipal Solid Waste (MSW) landfills are a burden for future generations because of the required long-term aftercare. To shorten aftercare, treatment methods have to be developed that reduce long-term emissions. A treatment method that reduces emissions at a lysimeter scale is re-circulation of leachate. However, its...journal article 2018

(author)The fundamental diagram (FD) describes the relation between the flow and density in equilibrium conditions. In this paper, we propose an estimation approach to estimate the FD based on data from moving observers. This approach consists of two main steps: (1) estimate flow and density for space-time areas based on trajectories of moving observers...conference paper 2018

Lu, Shoufeng (author), Knoop, V.L. (author), Keyvan-Ekbatani, M. (author)A two-Fluid Model (TFM) of urban traffic provides the macroscopic description of traffic state. The TFMs parameters are hard to calibrate, particularly for the dynamic traffic conditions. This leads to the TFM often being used to compare the quality of service through the plot of stopping time versus trip time of the vehicles in the network....journal article 2018
