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...

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...

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...

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....

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...

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...

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...

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...

Yuan, K. (author)
Earlier studies on the traffic flow on freeways reveal that queue discharge rate cannot<br/>reach as high as the free-flow capacity. This important phenomenon is called the<br/>“Capacity drop”, which indicates that the potential freeway capacity cannot be fully<br/>utilized when discharging traffic jams. Even though a majority of empirical and...

Extensive research is available on travel choice behaviour which occurs during evacuations in case of natural disasters. Due to the disadvantages of existing data collection techniques, more research is needed to better understand evacuation choice behaviour. The main objective of this thesis is twofold: (1) to develop, apply and assess a new...

How to model and simulate large pedestrian facilities accurately? This dissertation answers this question by analysing current pedestrian models and expanding one. The developed model (Nomad) describes pedestrians as individuals that minimise walking efforts. The model is expanded including behaviours that correspond to activities performed in...

To what extent can we model the movements of pedestrians who walk across a large-scale event terrain? This dissertation answers this question by analysing the operational movement dynamics of pedestrians in crowds at several large music and sport events in the Netherlands and extracting the key crowd movement phenomena. A conceptual model and an...

Nowadays we have all sorts of legislation to safeguard safety at home and at work. Safety management systems are supposed to safeguard safety issues at system level. We have advanced computer models to test system designs when still on the drawing board. Safety as a whole is very much safety conscious. Yet despite all our efforts accidents still...

When congestion becomes a problem on a road or road network, there are generally three main solution areas available to tackle it: construction, pricing or traffic management. Traffic management became an increasingly preferred option towards the end of the twentieth century as an alternative to construction in many cases. Traffic management...

Sag vertical curves (sags) are roadway sections along which the gradient increases gradually in the direction of traffic. Empirical observations show that, on freeways, traffic congestion often occurs at sags; actually, in some countries (e.g., Japan), sags are one of the most common types of freeway bottleneck. This thesis is the outcome of a...
