At the Faculty of Transport Sciences "Friedrich List" of the TU Dresden, the Institute of Traffic Telematics has been dealing with traffic telematics issues and applications for many years. At the Chair of Traffic Control Systems and Process Automation, the focus is on teaching and research in the areas of traffic and operations control systems, traffic control technology, traffic process automation and traffic management for both rail and road traffic.
In order to make current research and development results available to a broad professional audience, the chair publishes the series "Traffic Telematics" in loose succession of interesting contributions from its immediate field of activity, traffic telematics in general, and also contributions to interdisciplinary issues. It is hoped that the current research results will flow into practice and help to make traffic more fluid, resource-friendly and efficient.
The publication series is available in bookstores as well as online and can be cited at http://nbn-resolving.de/urn:nbn:de:bsz:14-qucosa2-339052

Brief description:
The eighth volume of the series "Schriftenreihe Verkehrstelematik" is dedicated to the research topics and selected publications of the year 2016 of the Chair of Traffic Control Systems and Process Automation of the Faculty of Transport Sciences "Friedrich List" of the Dresden University of Technology. Eleven contributions from national and international conferences and from journal publications of the staff members with the topics rail traffic, public transport, road traffic and bicycle traffic show the broad spectrum of traffic telematics applications and research of the professorship.
In the field of energy-optimal control in rail transport, results of the EU-funded project ON-TIME are presented with questions on real-time capable traffic management, driver assistance as well as timetable evaluation and optimization in rail systems. Contributions to the EU project CAPACITY4RAIL complement the considerations with questions on data exchange formats and formal descriptions of incident management processes in railroad operations.
New fields of application for driver information and assistance systems are shown with contributions on BikeNow - a mobile application for cyclists - and COSEL - a system for streetcars. Two articles present the promising results of the first practical application of the systems.
And automated driving functions and driver assistance systems are also a research topic in the field of road traffic management. For the REMAS project, simulation investigations with SUMO are discussed here as an example. Furthermore, in the context of quality management for the Dresden traffic management system VAMOS, it was analyzed which quality is achieved in the traffic situation assessment and how this can be upgraded by using an up-to-date traffic situation image and traffic situation information.

Brief description:
This thesis deals with the linking of conflict resolution and driver assistance systems with the aim of enabling the exploitation of the potentials of both systems.
After a review of the state of the art in both fields with a focus on applied algorithms as well as possible data structures for interfaces, the concept of the train running optimization plan as a set of train running corridors is developed. Different models and algorithms for vehicle dynamics calculations are analyzed. On this basis, a variant is selected that is suitable for vehicle dynamics calculations of conflict resolution, driver assistance and thus also for the interface solution to be developed.
In the following, an interface solution is developed that uses inputs from conflict resolution systems and calculates energy-optimized train running optimization plans. This results in train running corridors in such a way that they are suitable for dispatch to driver assistance systems. For this purpose, the track occupation sequences and the resulting temporal and spatial constraints for the train runs are modeled with a constraint program and optimized with the Matlab-nonlinear constraint solver. Ways to reduce the computational time of the method are discussed and implemented.
Finally, the evaluation of a case study based on two scenarios of European rail corridors follows, where the influences of the different modeling variants on solution quality and computational speed are investigated.

Band 6: Aspekte der Verkehrstelematik – ausgewählte Veröffentlichungen 2015

TUDpress 2016. Kartoniert, 128 Seiten
ISBN: 978-3959080743
Brief description:
The sixth volume of the series "Schriftenreihe Verkehrstelematik" gives an overview of the intermodal research topics of the year 2015 of the Chair of Traffic Control Systems and Process Automation of the Faculty of Transport Sciences "Friedrich List" of the Dresden University of Technology on the basis of selected publications. Seven selected articles of the staff, mainly published in the context of national and international conferences, were compiled for this purpose.
The first focus is on energy-optimal control and traffic management in rail transport. Here, the question is addressed how disturbances of rail operations in real-time operations management can be countered with mathematical methods. As a starting point, the generation of robust, stable and at the same time energy-efficient timetables is discussed. Furthermore, an attempt is made to use conflict resolution algorithms to prepare operationally updated timetables within the framework of operations management in such a way that implementation with on-board driver assistance systems is possible and energy-efficient operation is ensured.
The second part of the volume shows how the methods and algorithms of energy-optimal driving and a corresponding driver assistance system can be transferred to streetcars and also buses. Subsequently, the focus is entirely on private transport and the question of range optimization of electric vehicles by energy-efficient routing algorithms considering real-time traffic situation data is explored. As in rail transport, finding the optimal driving strategy is also supported here by driver assistance systems.

Brief description:
In the fifth volume of the series of publications on transport telematics, the focus is on intermodal research topics from selected publications of the Chair of Traffic Control Systems and Process Automation at the Faculty of Transport Sciences "Friedrich List" of the Dresden University of Technology in 2014. The contributions in this volume can be assigned to three main areas this year.
On the one hand, there are publications on the completed EU project ON-TIME, which is dedicated to the topic of traffic management and driver assistance as well as timetable evaluation and optimization in railroad systems.
Questions concerning traffic data with regard to the design of data interfaces, data acquisition and evaluation as well as the generation of traffic data by real data calibrated simulations are a second core topic. Here, the scope ranges from approaches in train running simulation of mainline railroads to power peak reduction in streetcars and light rail vehicles to traffic signal assistants in road traffic.
The third focus is on VAMOS, the traffic management system of the city of Dresden. In addition to a brief outline of the development and scope of the system, the use of the database is the starting point for several technical publications. Here, too, the professorship pursues a multimodal approach. Thus, articles about the increase of public transport quality on the one hand and assistance functions of individual transport for energy-efficient driving on the other hand show that VAMOS data can be used for different modes of transport.

ISBN: 978-3-944331-73-7
Brief description:
The fourth volume of the publication series Transport Telematics presents the intermodal research topics and their practical applications of the Chair of Traffic Control Systems and Process Automation at the Faculty of Transport Sciences "Friedrich List" of the Dresden University of Technology with selected publications of the year 2013. The focus of the research work lies on the one hand in the field of energy-optimal control in rail traffic and associated driver assistance systems, and on the other hand in the traffic management of road traffic.
Energy-optimal control in rail traffic is implemented by means of driver assistance systems not only in rail traffic, for example on the trains of the Harz-Elbe-Express, but also on streetcar and subway vehicles. In addition, the methods and procedures of energy-optimal control are used as part of approaches for modularized traffic management on railroads.
The traffic management system of the city of Dresden VAMOS forms the basis for the second research focus. Here, on the one hand, possibilities to microscopically simulate road traffic and to incorporate the traffic state data of VAMOS are investigated in the present volume. On the other hand, the question is investigated to what extent road closures can be reliably identified using the floating car data available in the system.
Five additional articles on both research topics have been published in the context of the international conference "3rd Models and Technologies for Intelligent Transportation Systems (3rd MT-ITS)" organized by the chair. These contributions have already been published in the conference proceedings as the third volume of the present series of publications on traffic telematics.

Band 3: Proceedings of the 3rd International Conference on Models and Technologies for Intelligent Transportation Systems 2013
Published by Thomas Albrecht, Birgit Jaekel und Martin Lehnert
TUDpress 2013. Kartoniert, 540 Seiten
ISBN: 978-3-944331-34-8
Brief description:
Challenges arising from an increasing traffic demand, limited resource availability and growing quality expectations of the customers can only be met successfully, if each transport mode is regarded as an intelligent transportation system itself, but also as part of one intelligent transportation system with “intelligent” intramodal and intermodal interfaces. This topic is well reflected in the Third International Conference on “Models and Technologies for Intelligent Transportation Systems” which took place in Dresden 2013 (previous editions: Rome 2009, Leuven 2011). With its variety of traffic management problems that can be solved using similar methods and technologies, but with application specific models, objective functions and constraints the conference stands for an intensive exchange between theory and practice and the presentation of case studies for all transport modes and gives a discussion forum for control engineers, computer scientists, mathematicians and other researchers and practitioners.
The present book comprises fifty short papers accepted for presentation at the Third Edition of the conference. All submissions have undergone intensive reviews by the organisers of the special sessions, the members of the scientific and technical advisory committees and further external experts in the field. Like the conference itself the proceedings are structured in twelve streams: the more model-oriented streams of Road-Bound Public Transport Management, Modelling and Control of Urban Traffic Flow, Railway Traffic Management in four different sessions, Air Traffic Management, Water Traffic and Traffic and Transit Assignment, as well as the technology-oriented streams of Floating Car Data, Localisation Technologies for Intelligent Transportation Systems and Image Processing in Transportation.
With this broad range of topics this book will be of interest to a number of groups: ITS experts in research and industry, students of transport and control engineering, operations research and computer science. The case studies will also be of interest for transport operators and members of traffic administration.

Band 2: Aspekte der Verkehrstelematik – ausgewählte Veröffentlichungen 2012

TUDpress 2013. Kartoniert, 132 Seiten
ISBN: 978-3-944331-18-8
Brief description:
The present volume provides an overview of the research work of the Chair of Traffic Control Systems and Process Automation at the Faculty of Transportation Sciences "Friedrich List" of the Dresden University of Technology in 2012. Twelve selected publications of the staff, mainly from national and international conferences have been compiled for this purpose. The broad research area of the chair, covering all land transport systems, has its main focus on energy-optimal control in rail transport and traffic management of road transport.
In the field of energy-optimal control in rail transport, the aspects of stop avoidance and dynamic running time control are described, for example, in the article "Predictive Energy-Efficient Running Time Control for Metro Lines". The article "Pilotierung eines Assistenzsystems zur kraftstoffsparenden Fahrweise im SPNV" focuses on the research and application area of driver assistance. In addition, the intermodal interactions between public transport and private transport are also addressed. The explanations in "Cooperative Traffic Signals for Energy Efficient Driving in Tramway Systems" illustrate how these traffic modes can be linked to mutual advantage with the help of a cooperatively operating control system for traffic nodes controlled by light signals.
The traffic management system of the city of Dresden VAMOS, which is presented in "The Traffic Management System VAMOS - from Research to Regular Operation", forms the basis for a large part of the further, mainly road traffic related work. Innovative approaches to collect and fuse relevant data from existing detectors and experiences from the operation of the system are complemented by the presentation of further possibilities for the use of traffic data, as shown for example in the paper "Microscopic Real-Time Simulation of Dresden Using VAMOS-Data".

Band 1: Energieversorgung und Betrieb eines Nahverkehrssystems mit on-board-Speicher und Nachladepunkten
Published by Martin Lehnert

Brief description:
In the present work, a model for the description of the energy demand of electric vehicles of public transport is developed on the basis of probability distribution densities, which in particular allows a dimensioning of the on-board energy storage system and the wayside energy supply infrastructure in a catenary-free operating concept (docking principle).
In contrast to deterministic energy demand sizing, stochastic modeling with a combination of Markov chain and semi-Markov process enables the consideration of reliability constraints in terms of mission accomplishment. Finally, it can be used to optimize the size of hybrid vehicle energy storage systems and the location of recharging stations along the route. The effectiveness of the modeling is demonstrated using a case study based on measured data for a streetcar vehicle.
For the design of the wayside energy supply infrastructure, the load profiles of the recharging process are derived in terms of time-weighted load duration curves for characteristic network topographies. On the one hand, a charging of the on-board energy storage from a wayside energy pre-collection station (docking station) brings a considerable smoothing of the power curve during energy draw. On the other hand, an electrical connection of this station to the low-voltage grid is possible within a few hundred meters in ordinary urban settlement structures.
