Dissertations and Habilitations
As members of our research groups, Ph.D. students also developed a scientific basis for public transport planning, traffic modeling and transportation technology.
The theses are usually conducted using contacts from practice.
Let's show some of them.
Presentation of selected dissertations
Transport optimization of zones-size in hierarchy-segmented passenger transport concepts
Vávra, Rudolf; Dissertation; 2024
This dissertation addresses hierarchically segmented passenger transport Concepts in public transport, with a particular focus on zone-oriented service within monocentric networks. The primary objective of this thesis is to develop a model for the optimization of zone-oriented timetables based on transport-related and operational-economic criteria. Initially, the dissertation provides a comprehensive summary of the prevalent forms of multi-level passenger service in public transport, analysing their transportation and operational-economic characteristics, as well as their implications for railway capacity utilization. Subswquently, the study identifies and examines the key determinants influencing the positioning of zone boundary stations, which delineate the borders between adjacent agglomeration zones. The thes then conducts a rigorous analysis of the current state of research, focusing on studies that explore the optimization of timetables and operational processes from transportation and operational-economic perspectives. Additionally, it scrutinizes contemporary methods and approaches for determining the location of zone boundary stations. Following the theoretical groundwork, the dissertation introduces the proposed optimization model, detailing its formulation and practical application. As part of the validation process, the model was tested on four real-world railway lines in the Czech Republic, yielding succesful outcomes. Finally, the study concludes by articulating potential directions for future research that could further address the challenges and extend the contributions presented in this work.
Transport planning in public transport systems
Janoš, Vít; Habilitation; 2022
This thesis focuses on the issue of transport planning in public transport systems, with a focus on passenger rail transport. The individual steps of transport planning are presented, as well as selected procedures and methods, both exact and heuristic, which are applicable in transport planning. In this work, the author tries to link issues of transport behaviour, the discovery of transport relations and methods of line planning so that, when the presented procedures are applied, a more favourable modal split of public transport can be achieved in the final effect.
Macroscopic Transport Model Modification
Kříž, Milan; Dissertation; 2020
The dissertation deals with the issue of macroscopic transport modelling. The aim of this dissertation is to extend the standard procedure for calculating the macroscopic transport model by a model that determines for each zone of the transport model the share of individuals with public transport season tickets or an available car. The use of these mobility tools is not considered as a mere input into the transport model, but hte use of these tools is considered as dependent on the various factors described in this thesis. The hypotheses were verified by the multinomial logit model, the nested-logit model and the mixed logit model. The thesis presents a new procedure that includes these factors in the macroscopic transport model.
Periodic Freight Train Paths in Network
Drábek, Michal; Dissertation; 2014
The central theme of the work is "freight periodic timetable", i.e. a topic that in the research of timetables and track capacity until then occurred rather marginally. First, the issue of creating freight train paths within the integrated periodic timetable (ITJŘ) of passenger transport framework is discussed. Given the nature of rail freight, the conclusion is confirmed that it makes sense to introduce periodic train paths as a capacity offer rather than systematic timetables for freight trains. The design is verified on two case studies. The results confirm significant economic benefits of the proposed procedure.
