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...

Landman, R.L. (author)
Due to the ever-growing traffic demand, urban areas all over the world are<br/>facing serious congestion problems. To mitigate the negative impacts of congestion, for many years more roads were built and traffic management measures locally implemented. Regardless all the extra asphalt and local control solutions, nowadays demands are often still...

Zomer, L. (author)
Every day residents and visitors find their way through the complex urban<br/>network to go to work or get education, or go sightseeing. This thesis<br/>contains studies on the development of spatial knowledge, activity patterns,<br/>and route dynamics of cyclists. The contributions and findings narrowed<br/>the gap between research on travel...

Gavriilidou, A. (author)
As the title suggests, cyclists are the main topic of this dissertation<br/>and more specifically, their behaviour while they are ‘in motion’. The<br/>term ‘in motion’ is used in the title to represent microscopic operational<br/>cycling behaviour, which is the behaviour of cyclists, treated as individuals<br/>(microscopic level), while they are...

Knowledge about the way how the bicycle is used for activity participation is still scarce. This thesis provides empirical insights into typical activity-travel behaviour of cyclists. A special focus is put on the spatial dimension of activity-travelling by bicycle and its determinants. The findings can be used to design more bicycle-friendly...

The past decade has seen vast advancements in various ICT (Information Communication, and Technology) platforms. These advancements have enabled the rise of innovative mobility solutions e.g. on-demand transport services. Such solutions offer flexible transport services to users in which users can receive tailor-made mobility solutions....

Alonso González, M.J. (author)
A new range of tailored, on-demand mobility alternatives are emerging worldwide; amongst these are pooled on-demand services, i.e., shared ride-hailing services such as UberPOOL or ViaVan. Simulation studies have shown the potential benefits of these services in urban areas, yet their ridership is still very limited. This thesis examines the...

Yap, M.D. (author)
Public transport systems can be subject to disruptions, which have negative impacts on passengers. Disruptions can result in additional in-vehicle time, waiting time, transfer time and extra transfers for passengers. In addition, perceived journey times might increase due to higher crowding levels on public transport services. Public transport...

Traffic state information is crucial for different applications, e.g., in design and operation of road traffic networks, and in navigation services. Traffic sensing data, e.g., loop-detector data, may directly provide the desired information. Alternatively, the traffic state information may be estimated with data that only provides partial and...

Ton, D. (author)
Due to increasing urbanisation rates worldwide combined with growing transportation demand, liveability of the urban environment is under pressure (UN, 2018). In response, many governments worldwide have set goals for increasing the share of trips made using sustainable modes of transport, such as walking and cycling. The use of active modes (i...

Shu, Y. (author)
Modeling is a promising approach to understand and predict the safety and efficiency of maritime traffic in ports and waterways. Different types of models have been developed over the years. Nevertheless, several important scientific challenges still remain. For instance, few models consider vessel behavior in ports and waterways under the...

Over the past decades, transport and traffic models have become powerful tools for transport and traffic practitioners and academics all over the world. Most of these commercial model packages provide proprietary and closed source software, which generally implies that users are not enabled to freely edit, modify and extend the code....

van Beinum, A.S. (author)
In the vicinity of motorway ramps, multiple manoeuvres are performed by drivers that are entering or exiting the motorway, and by drivers that anticipate on, or cooperate with, the other entering and exiting vehicles. These manoeuvres involve lane-changes, changes in speed, and changes in headways. This results in changes in lane flow...

document
Bellsola Olba, X. (author)
Vessel traffic in ports is a key issue due to the high increase in vessel flows that lead to busier waterways. This dissertation presents novel methodologies to assess vessel traffic in ports based on capacity and risk independently and jointly. These methodologies have been applied to case studies using simulation models and AIS data. They...

Varotto, S.F. (author)
Adaptive Cruise Control (ACC) and automated vehicles can contribute to reduce traffic congestion and accidents. Field operational Tests have shown that drivers may prefer to deactivate ACC systems that are inactive at low speeds in dense traffic conditions and before changing lanes. These transitions between automated and manual driving are...

Han, Y. (author)
Traffic congestion has become a global issue that has a significant impact on our societys productivity. Its negative effects not only lie in the travel delays and unsafe conditions that it brings to road users, but also many aspects of our lives such as the air we all breathe. Construction and traffic management are typical alternatives for...

Even though rail is more energy efficient than most other transport modes, the enhancement of energy efficiency is an important issue for railways to reduce their contributions to climate change further as well as to save costs and enlarge competition advantages involved. This thesis is motivated by the challenges in improving energy efficiency...

Controlling road traffic networks is a complex problem. One of the difficulties is the coordination of actuators, such as traffic lights, variables speed limits, ramp metering and route guidance, with the aim to improve the network performance over a near-future time horizon. This dissertation develops algorithms that specifically balance fast...

Mainline railways in Europe are experiencing increasing use as the worldwide demand for passenger and freight transport is growing across all transport modes. At the same time, much of the existing railway network is reaching its capacity and has become susceptible to disturbances. This thesis creates, optimizes, and evaluates railway timetables...
