van Erp, P.B.C. (author), Thoen, Sebastiaan (author), Knoop, V.L. (author), Hoogendoorn, S.P. (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

Zhou, Y. (author), Daamen, W. (author), Vellinga, T. (author), Hoogendoorn, S.P. (author)Due to the increasing ship traffic flow in ports, maritime traffic safety has attracted much atten-tion. In addition to traffic flow, the ship safety in restricted waters is influenced by external navigational fac-tors (visibility, wind and current), encounter situations and human factors on board. In this paper, we investi-gate the effect of...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

Varotto, S.F. (author), Farah, H. (author), Toledo, T (author), van Arem, B. (author), Hoogendoorn, S.P. (author)Automated vehicles and driving assistance systems such as Adaptive Cruise Control (ACC) are expected to reduce traffic congestion, accidents and levels of emissions. Field Operational Tests have found that drivers may prefer to deactivate ACC in dense traffic flow conditions and before changing lanes. Despite the potential effects of these...conference paper 2017

Knoop, V.L. (author), Keyvan-Ekbatani, M. (author), de Baat, Marco (author), Taale, Henk (author), Hoogendoorn, S.P. (author)Freeways form an important part of the road network. Drivers’ behavior can be split in longitudinal (acceleration and deceleration) and lateral behavior (lane changing). The combination of these two behaviors on freeways play a key role in traffic operations. This paper tries to describe the driving behavior, emphasizing the relation between the...conference paper 2017

Alonso González, M.J. (author), van Oort, N. (author), Cats, O. (author), Hoogendoorn, S.P. (author)Mobility as a Service (MaaS) is entering the transportation market. MaaS aims at the full integration of the existing transportation services and it offers tailored mobility packages to the user. In MaaS ecosystems, on-demand services play an important role as complement to public transport due to their flexibility. However, to date, most...conference paper 2017

Ton, D. (author), Duives, D.C. (author), Cats, O. (author), Hoogendoorn, S.P. (author)The specification of the choice set for travel behaviour analysis is a non-trivial task, as 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 severe errors to the specified choice set: false...conference paper 2017

Ton, D. (author), Cats, O. (author), Duives, D.C. (author), Hoogendoorn, S.P. (author)Nowadays, the bicycle is seen as a sustainable and healthy substitute for the car in urban environments. The Netherlands is the leading country in terms of bicycle use, especially in urban environments. Yet route choice models featuring inner-city travel that include cyclists are lacking. This paper estimates a cyclists’ route choice model for...conference paper 2017

Such mobility solutions offer on demand transport services and hence can solve the problems inherent with traditional line based and schedule based public transport systems. It is essential...conference paper 2017

The availability of smart card data gives opportunities to better quantify disruption impacts on passengers’ experienced journey travel time and comfort. For this, accurate journey inference from raw transaction data is required...conference paper 2017

Daamen, W. (author), Yuan, Y. (author), Duives, D.C. (author), Hoogendoorn, S.P.

For a timely deployment of crowd management measures, continuous information on the real-time traffic state on the...conference paper 2016

Yuan, K. (author), Knoop, V.L. (author), Hoogendoorn, S.P. (author)Capacity drop indicates that the queue discharge rate is lower than the road capacity. Due to the capacity drop, traffic delays increase once queues form. Researchers find that queue discharge rates vary in different traffic conditions. Empirical data shows that the queue discharge rate increases as the speed in congestion increases....conference paper 2016

(author)Turbulence in traffic is a commonly known phenomenon, but the exact characteristics of this phenomenon are not yet clear. It reflects individual changes in speed, headways, and lanes in the traffic stream. The currently used freeway design guidelines prescribe different measures for handling turbulence, such as sufficient ramp spacing, and...conference paper 2016

Urban network throughput optimization via model predictive control using the link transmission modelVan de Weg, G.S. (author), Keyvan Ekbatani, M. (author), Hegyi, A. (author), Hoogendoorn, S.P. (author)Developing practicable and efficient real-time signal control strategies for urban road networks is a major challenge with significant scientific and practical relevance. For the sake of practical feasibility, many urban traffic control strategies are based on simplified models. In this way, a trade-off can be made between controller accuracy,...conference paper 2016

(author)Weaving is defined as the crossing of two streams travelling in the same direction along a significant section of the road without the assistance of traffic control devices. Merging and diverging vehicles need to make one or more lane-changes in a limited space and time, determined by the weaving section length. This situation creates intensive...conference paper 2016
