PhD Council

About the Council

The PhD-council is the bridge between the PhD-students and the TRAIL-management. We act as an advisory board for the TRAIL-management regarding the TRAIL strategy, the course program and the TRAIL congress. Moreover, we organize PhD activities or social events every now and then for you to socialize or network with your peers.
If you have any questions, suggestions, ideas, problems or complaints, you can contact us by email or in person. And don’t forget to become a member of the TRAIL Members group on LinkedIn!

Research topic:
My PhD research aims at exploring the demand for innovative demand-driven mobility services based on platform technology. An example of these new services is the concept of Mobility as Service (MaaS). The assessment and prediction of consumers demand for MaaS require to take into account its core characteristics (e.g. integration of transport modes, integration of transport-related services and the presence of a single digital platform) together with the associated issues (e.g. uncertainty, social influence, network effects). Specifically the objective of my study is to develop a comprehensive modelling approach able to investigate the individual decision regarding subscription to a MaaS platform and the consequent purchase of mobility packages of services (adoption process). It also aim to provide insights about the dynamics affecting the diffusion of MaaS throughout the society.

Background and interests:
Education in Environmental Engineering (BSc and MSc), with a specialization on environmental sustainability issues. Professional experience in international consultancy firm and research institutes with a focus on smart cities, sustainable urban mobility and the role of ICTs in sustainable development. Interests include innovation adoption in transportation, transportation demand modelling and decision making processes.

Research topic

Developing and validating dynamic, activity – based travel demand models of group decisions under uncertainty is the main focus of my research. The aim is to develop alternatives to currently used models. Human behavior is a really important factor to be taken into account so as to shed some light on how people make sequential decisions under uncertainty. This will be investigated not only in terms of travel behavior research, but also of human choice and decision making based on other fields, such as social psychology. Examining more complex decision problems and developing comprehensive models of activity-travel behavior of individual and household decision making under uncertainty is absolutely imperative to making a step further in the existing applications.

Background and interests

Education in Civil Engineering, specialization in Transport Planning and Engineering. Diploma thesis about “Analysis of alternative scenarios for managing traffic incidents through microsimulation”. Interests include urban planning, transport modelling, uncertainty analysis, human behavior, decision making

Research topic:
State-of-the-art, personalized travel information is expected to be potentially successful in directing network states towards the efficient system optimum (collective benefit) instead of the inefficient user equilibrium (individual benefit). In order to assess this potential of travel information, both the individual level and the network level are considered. An experiment will be conducted using a smartphone application in order to gain insight in human response towards different information strategies. These individual findings will be translated to the network level using simulation.

Background and interests:
Education in Civil Engineering, specialization in Transportation Engineering and Management. Master thesis about ‘One route or the other? Development and evaluation of a day-to-day route choice model incorporating the principles of inertial behavior and quantification of the indifference band based on a real-world experiment’ conducted at the Virginia Tech Transportation Institute in Blacksburg, Virginia, USA. Interests include travel behaviour, discrete choice modelling and network optimization.

Research Topic

Stakeholders’ acceptability of smart road pricing instruments’. In order to design and implement road pricing measures that can effectively manage congestion and are accepted by the public and politicians, it is important to have insights in the acceptability of these instruments. Because of the longstanding problems concerning feasibility of traditional road pricing instruments, recently the interest has increased for the development of road pricing instruments that are based on rewarding or trading (instead of charging). The aim is to gain insights in the acceptability of the public and politicians of these novel road pricing concepts.

Background and interests

Bachelor in Architecture. Master in Transport, Infrastructure and Logistics (with a specialization in Policy). Both at the Delft University of Technology. Interest include cycling, politics and the combination of quantitative and qualitative research methods.

Research Topic

The focus of my research is on railway timetabling and my research is done in close cooperation with Netherlands Railways (NS). I want to integrate information about passengers flows (based on an OD-matrix) in the process of periodic timetabling for Netherlands Railways. The aim is to build an algorithm that starts at a macroscopic level and adds more details while running, to end up with a sketch of a possible timetable.

Background and interests

Education in Applied Mathematics at Delft University of Technology, thesis on a timetabling research at NS to improve current planning algorithms. Interested in planning and optimization problems and complex puzzles.

Research Topic:
The aim of this PhD research is enhancing sustainability in fresh food supply chains by improving logistic resource utilization while read times are reduced. To realize this will be focused on collaboration concepts, in particular vendor managed inventory (VMI). First is analyzed what exactly the advantages of VMI are in this context and how these are affected by supply chain conditions as perishable products and different supplier properties. Next is explored how VMI can realize sustainability improvements in a fresh food supply chain by sharing inventory and transportation capacity among suppliers.

Background and interest:
Education in Industrial Engineering and Management (BSc & MSc), specialization in production technology and logistics, at the University of Groningen. Master’s thesis on “A solution approach for deriving alternative fuel station infrastructure requirements”. Interest include statistical analysis, simulation modeling and optimization in the field of logistics.
