Dissertations / Theses on the topic 'Transport telematics'

The key aim of this research is to contribute to the development of a robust and reliable navigation system in order to support the positioning requirements of advanced transport telematics (ATT) services. This is achieved through the development of high integrity map matching algorithms. In the last two decades, satellite navigation technology, especially the Global Positioning System (GPS), has established itself as a major positioning technology for land vehicle navigation. Deduced Reckoning (DR) sensors, which consist of an odometer and a gyroscope, are commonly used to bridge any gaps in GPS positioning. However, DR sensor positioning errors can grow rapidly if not controlled by another sensor or system such as GPS. Digital road maps are used for spatial reference of the vehicle location via a process known as map matching. Map matching algorithms use inputs generated from positioning technologies and supplement this with data from a high resolution digital road network map to provide an enhanced positioning output. Existing map matching algorithms have weaknesses which decrease their capability to support many ATT services. Three high integrity map matching algorithms are developed in this research. They are the improved topological, probabilistic, and fuzzy logic map matching algorithms. These algorithms are successfully implemented, tested and validated using real field test data. A reference (truth) vehicle trajectory, as determined by high accuracy GPS carrier phase positioning, is used to validate the algorithms. The integrity (level of confidence) of the algorithms is analysed by taking into account the uncertainty associated with the map-matched location and the error sources associated with the navigation system and the digital map. The effects of navigation systems and digital map quality on the performance of map matching algorithms are also investigated for suburban and urban road networks. The results suggest that all three map matching algorithms developed in the course of this research have the potential to support the navigation function of a wide range of ATT services. However, of the three, the fuzzy logic map matching algorithm offers the highest performance, both in terms of link identification and location determination.

The focus of this thesis is the assessment of telematic systems for road freight transport from a planning perspective. The aim is to support strategic decisions related to architectural choices for such systems, with the possibility to achieve synergies by supporting multiple telematic services. The past decade has witnessed enormous growth in cargo volumes resulting in increasing demand for transport capacity. To match this increasing demand only with expansion of infrastructure, e.g. road and vehicles, does not seem to be a sustainable strategy. One of the few approaches with the potential to improve the use of current transport capacity is the integrated use of modern information and communication technology, otherwise known as telematic systems for road transport, an important component within Intelligent Transport Systems (ITS). This type of systems can deliver multiple services that can be used to improve the efficiency and safety of road freight transport. However, attempts to unleash the potential of telematic systems and make maximum possible use of the available transport capacity have been hindered by several challenges ranging from planning and design to development and deployment. Considering the large scope of possible telematic services that can potentially be deployed in road freight transport, this thesis suggests a framework in order to enable structured assessment of telematic systems. Based on the suggested framework, a set of potential transport telematic services are identified and a method for quantifying the value of the services to society is developed. The suggested method takes into account the expected impact on different transportation challenges, such as accidents, fuel consumption, and infrastructure maintenance. Quantitative methods are provided for studying the value of services sharing a common infrastructure. Using quantified benefits of services and costs of various functionalities required by telematic services, the concept of a multi-service architecture is investigated using optimization methods, which handles the multi-dimensional relations between different services that are otherwise difficult to analyze with traditional cost-benefit analysis. The analyses show which telematic services can be achieved with different approaches, such as vehicle-to-vehicle communication, vehicle-to-infrastructure communication, etc. Although multi-service architectures are promising, several challenges need to be overcome, including security, service quality, privacy, and business models. The knowledge gained from the work presented in this thesis can be valuable for different stakeholders, such as governments, service providers, and transport service users, in fostering the planning, design, development, and deployment of telematic systems in transport.

This thesis presents the combination of MPLS-TP protocol with an integrated hybridnetwork, the Opmigua network. It is presented that the MPLS-TP protocol is applicableand follows all the requirements to be compatible with an Opmigua network. Differentnetwork scenarios, combining packet and circuit switching properties with MPLS-TPlabels, are presented. At the beginning of this thesis, are provided the characteristics and requirements of MPLS-TP protocol which the standardization of this is on going. Furthermore, it is explained how the MPLS-TP management and the forwarding plane work. Some references are also given not only to OAM mechanisms, but also to control plane that the MPLS-TP uses. We use both, global and local significance MPLS-TP labels for distinguishing theGuaranteed Service Traffic (GST) packets from Statistical Multiplexing (SM) packets.Using this method, we have concluded some results, as it concerns GST and SMtraffic. GST packets take a global significance label value until to reach the destination node. On the other hand, SM packets take local significance labels for each path into an Opmigua network which follow Optical Packet Switch (OPS) networks. We have proposed a new method for differentiation of packets from low to high priority using extension headers of Internet Protocol v6 either Destination Options Header(DOH) or MPLS-TP as an extension header. The result that we have derived is highand low priority packets are differentiated at ingress Opmigua network which GST packets take global significance MPLS-TP label following Optical Cross Connect (OXC) network and SM packets change per each Label Switched Path (LSP) local significance MPLS-TP labels until to reach the destination. Finally, two MPLS-TP path protection schemes, facility bypass and restoration usingdetours were combined with Opmigua network to provide failures for both, GuaranteedService Traffic (GST) packets and Statistical Multiplexing (SM) packets.

A quantidade de problemas relacionados ao trânsito cresce à medida que aumenta a quantidade de automóveis trafegando nas ruas das cidades. O atual estágio de desenvolvimento das tecnologias de dispositivos eletrônicos permite que sistemas sejam criados para reduzir esses problemas. Muitos estudos s˜ao realizados na tentativa de encontrar as melhores maneiras de reduzir problemas como engarrafamento nas vias e emissão de poluentes. Uma das áreas mais estudadas é a telemática de transporte, que é a união entre sistemas de tecnologia da informação modernos e telecomunicações, aplicadas à indústria dos transportes. Nesse trabalho, é proposta uma infra-estrutura que visa reduzir os problemas de custo de implantação de sistemas de telemática de transporte. A arquitetura dessa infraestrutura foi concebida de forma que o sistema pudesse ser extensível. Para validação da infra-estrutura, um software foi desenvolvido para telemática de transporte.
The quantity of problems related to transit grows as the amount of cars transiting the city’s streets increase. The current stage of development of electronic devices technology allows the creation of systems designed to reduce these problems. Many studies are performed in an attempt to find the best ways to reduce problems like traffic jam on roads and emission of pollutants. One of the most studied areas is the transport telematics, which is the joint of modern systems of information technology and telecommunications, applied to transport industries . In this dissertation, it is proposed an infrastructure to reduce the cost problems of introduction of transport telematics at automobiles. This infrastructure architecture was conceived in ways to permit the system to be extensible. To validate the infrastructure, a software was developed for transport telematics.

Floating Car Data (FCD) besitzen eine sehr breite Palette an Anwendungsmöglichkeiten, die aber teilweise noch keine massenhafte Verbreitung gefunden haben, auch wenn das Innovationspotenzial als sehr hoch eingeschätzt wird. Dies begründet sich in erster Linie durch die meist relativ großen Erfassungsintervalle bei der derzeitigen FCD-Erfassung. In Dresden ist ein Taxi-FCD-System in Betrieb, welches sich durch eine sehr hohe Detektionsdichte auszeichnet. Die Fahrzeugpositionen werden mindestens alle 5 Sekunden aufgezeichnet. Damit bestehen ausgezeichnete Möglichkeiten, mögliche Mehrwerte zu prüfen und Prototypen zu etablieren. Getestet wurde u. a. die Generierung von Straßennetzabbildern. Im Dauerbetrieb befindet sich die FCD-basierte Verkehrslageermittlung.

This report studies the possibility of integrating Transport Management Services (TMS) in a low-cost platform called Communicator 200 (C200). The platform is developed by Scania and is a black box that manages vehicle data, positioning, and wireless communication. The C200’s main purpose is to connect a hauler’s vehicles to their office system via wireless links and Internet. The thesis describes the design and implements a prototype of a service called Messaging that is used to send text messages between truck and office. The prototype is evaluated and tested with different web browsers in various hand-held terminals with different screen sizes. The main conclusion is that it is technically possible to integrate TMS in the C200 without altering the platform architecture too much.

C200 huvudsyfte är att sammankoppla ett åkeris fordon med deras kontorssystem via trådlösa förbindelser och Internet. Rapporten beskriver designen och implementerar en prototyp av en tjänst kallad Messaging som används för att skicka textmeddelanden mellan lastbil och kontor. Prototypen utvärderas och testas mot webbläsare i olika handhållna terminaler med olika skärmstorlekar. Huvudslutsatsen är att det är möjligt att integrera transportledningstjänster i C200 utan att ändra plattformens arkitektur alltför mycket.

The goal of the thesis is to give reader a detailed description of the Czech electronic toll system with emphasis to the potential future system development and infrastructure toll extension. The National Transportation Policy, legislative framework concerning the infrastructure tolling, and particular European toll systems are described in the first part of the thesis. Within the other part of the thesis, the reader is given a simplified cost-profit model of future toll extension efficiency to evaluate the optimal outcome of the toll extension.

This thesis is about the design of a Telematics for Totally Transparent Transports System

(T4 System). T4 System combines Wireless Sensor Network (WSN) technology with

ordinary fleet management systems to monitor and track cargo on a global scale. This

means that the cargo itself and not the vehicle transporting the cargo will be observed.

This has the advantage that a change in the transportation method can be made without

interrupting the tracking device. T4 System is not only a simple tracking device which only

monitors the transportation conditions; it also interacts with the chain of transportation

in case of a faulty situation, to provide the possibility to correct the error.

To keep the transportation process as transparent as possible T4 System uses a two way

communication and control strategy which allows, e.g. the customer, to check and/or

update the transport conditions or measurement parameters, respectively, in run-time,

when the situation demands it.

In this thesis, methods for using computer-based models as support tools for assessing Transport Telematic Services (TTSs) are studied. Such assessments provide one way to understand how TTSs can address problems caused by transportation, such as accidents, emissions, and energy consumption. TTSs are services based on telematic systems which are Intelligent Transport Systems (ITS) involving the integrated use of information and communication technologies in transport. The focus is on TTSs that are relevant for road freight transport, even though the suggested methods can easily be adapted for TTSs in other areas. We characterize TTSs, e.g., in terms of their functionalities, and apply computer-based modeling for pre-deployment assessment of various TTSs (from an ex-ante perspective). By analyzing information provided by the suggested computer-based models, it is possible to make an informed decision whether to (or not to) deploy a given TTS. A review of previous studies reveals information about relevant TTSs for freight transport in areas such as driver support, administration, safety, traffic management, parking, and goods handling. A hierarchical clustering algorithm and a k-minimum spanning tree algorithm were employed to analyze synergies of TTSs. Synergies can enable identification of sets of TTSs that can lead to cost savings if deployed on a common platform (cf. Multi-Service Architectures). An analytical model inspired by the net present value concept is used to estimate quantified societal benefits of TTSs. An optimization model is formulated and solved using a branch and bound method to determine an optimal combination of TTSs taking into consideration societal benefits, costs, dependencies, and synergies. The optimization model also addresses possible system architectures for achieving multiple TTSs. Dominance rough set approach is used to assess and compare benefit areas for TTSs specific to truck parking. The benefit areas are suggested with the help of conceptual modeling, which describes functional models of a system in terms of states, transitions among states, and actions performed in states. The main scientific contributions of the thesis are in suggesting new quantitative models, extending and applying existing models in the assessments of TTSs, and obtaining results that can help decision-makers select TTSs for medium-to long-term investments. Researchers can employ and build on the proposed methods when addressing different scenarios (geographic or organizational) involving similar TTSs. By studying a range of TTSs and possible Multi-Service Architecture concepts for such TTSs, the thesis contributes to achieving convergence of TTSs in a Multi-Service Architecture environment that will improve cost efficiency, minimize redundancies, and encourage the establishment of standards in the deployment of TTSs in road freight transport. TTSs implemented in such an environment can contribute to optimizing available capacity, accuracy, speed, and efficiency of road freight transport systems.

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.

Im fünften Band der Schriftenreihe Verkehrstelematik stehen die intermodalen Forschungsthemen aus ausgewählten Veröffentlichungen das Jahres 2014 der Professur für Verkehrsleitsysteme und prozessautomatisierung an der Fakultät Verkehrswissenschaften „Friedrich List“ der Technischen Universität Dresden im Fokus. Die Beiträge des Bandes können in diesem Jahr drei Schwerpunkten zugeordnet werden. Dabei handelt es sich zum einen um Veröffentlichungen zum abgeschlossenen EU-Projekt ON-TIME, das sich dem Thema Verkehrsmanagement und Fahrerassistenz sowie Fahrplanbewertung und optimierung in Bahnsystemen widmet. Fragestellungen zu Verkehrsdaten hinsichtlich des Designs von Datenschnittstellen, der Datenerfassung und -auswertung sowie des Erzeugens von Verkehrsdaten durch Realdaten-kalibrierte Simulationen sind ein zweites Kernthema. Hier reicht die Spannweite von Ansätzen bei der Zugfahrtsimulation der Vollbahn über Leistungsspitzenreduktion bei Straßen- und Stadtbahnen bis hin zu Lichtsignal-Assistenten im Straßenverkehr. Den dritten Schwerpunkt bilden Beiträge zum VAMOS, dem Verkehrsmanagementsystem der Stadt Dresden. Neben einem kurzen Abriss über Entstehung und Umfang des Systems ist die Nutzung der Datenbasis Ausgangspunkt für mehrere Fachpublikationen. Auch hierbei verfolgt die Professur einen multimodalen Ansatz. So zeigen Artikel über die Steigerung der ÖPNV-Qualität einerseits und Assistenzfunktionen des Individualverkehrs zur energieeffizienten Fahrt andererseits, dass VAMOS-Daten für verschiedene Verkehrsträger nutzbar sind.

Die Verkehrstelematik, im Englischen als Intelligent Transport Systems (ITS) bezeichnet, kann durch die Verbindung von Telekommunikation, Informatik und Automatisierung wesentlich zur Sicherung der Mobilität beitragen. Dabei kann durch Erfassen, Übermitteln, Verarbeiten und Darstellen von Verkehrsdaten in Telematiksystemen der Verkehr prognostiziert, gesteuert, gelenkt, geleitet und organisiert werden. An der Fakultät Verkehrswissenschaften „Friedrich List“ der TU Dresden beschäftigt sich das Institut für Verkehrstelematik mit verkehrstelematischen Fragestellungen und Anwendungen. An der Professur für Verkehrsleitsysteme und -prozessautomatisierung stehen dabei Lehre und Forschung in den Themengebieten Verkehrs- und Betriebsleitsysteme, Verkehrssteuerungstechnik, Verkehrsprozessautomatisierung und Verkehrsmanagement sowohl des schienengebundenen als auch des straßengebundenen Verkehrs im Vordergrund. Um aktuelle Forschungs- und Entwicklungsergebnisse einem breiten Fachpublikum verfügbar zu gestalten, veröffentlicht die Professur mit der Schriftenreihe „Verkehrstelematik“ in loser Folge interessante Forschungsthemen und Beitrage aus ihrem unmittelbaren Wirkungsfeld, der Verkehrstelematik allgemein und darüber hinaus auch Beitrage zu interdisziplinär aufgestellten Fragestellungen. Damit verbunden ist die Hoffnung, dass die aktuellen Forschungsergebnisse in die Praxis einfließen und dabei helfen, den Verkehr flüssiger, ressourcenschonender und effizienter zu gestalten.
Traffic telematics and Intelligent Transport Systems (ITS) can significantly contribute to securing mobility by combining telecommunications, information technology and automation. By capturing, transmitting, processing and displaying traffic data in traffic emblematic systems, the traffic can be predicted, controlled, directed, managed and organized. The Institute of Transport Telematics at the Faculty of Traffic Sciences 'Friedrich List' of the Technische Universität Dresden (TUD) deals with traffic telematics issues and applications. Teaching and research in the fields of traffic guidance and operation control systems, traffic control technology, process automation and traffic management of both rail-bound and road-bound traffic are in the focus of the Chair of Traffic Control and Process Automation. In order to make current research and development results available to a broad professional audience, the professorship publishes interesting research topics and contributions from their immediate field of action, namely traffic telematics in general, and also contributions to interdisciplinary issues with the series 'Verkehrstelematik'. Linked to this is the hope that current research findings will be put into practice and help to make traffic smoother, Eco-friendly and more efficient.

The thesis is about a transport Infrastructure payments in the selected transport branches of the Republic of Belarus. The first part is about a general description of the transport infrastructure of the country that connects the European countries with the Russian Federation and the Baltic States. Focus on the actual state, quality, development of the infrastructure. The second part - the description of the methods and tools of payment. In connection with a progressive development of road infrastructure and different methods of payment more attention is given to this type of communication. There are several systems of road payment in the world. The first method is based on the principle of time, such as vignettes. Another method is payment before road use (Toll). The first method is not working in Belarus, so the work described the second method. The last part of the thesis is about the payment on the certain types of transport infrastructure in Belarus. Focus on such transport types as rail and road transport, also made attention to the air and river transport.

This Master's thesis examines the possibility of implementing an intelligent transport system for monitoring road vehicles carrying dangerous goods through the territory of the Czech Republic, for the purpose of providing relevant information to emergency responders in the event of an accident involving such vehicles. The aim is to explore whether, and how, can radio-frequency identification technology be used in such a system. The scope of the research is not limited to technical aspects of the solution. Various options are considered in terms of capital costs, complexity of the required information system and impact on shippers and carriers from an economic and business process standpoint. The paper briefly describes the current legislation concerning the transport of dangerous goods, the existing processes and entities involved in transport and handling of traffic accidents. Following is a comparison of several possible implementations of the monitoring system.

[EN] This thesis has been created within the framework of the interoperability of the networks of sensors in industrial environments, using standard SWE (Sensor Web Enablement). It has developed from the participation in different research projects, within the research group SATRD (Distributed Real Time Systems and Applications) of the Communications Department of the UPV. Has gone a long time since the appearance of the first sensors that were only able to respond to a stimulus, to the concept of sensor web, where sensors can be remotely configured, perform actions and process and integrate data from other sensors. Nowadays, the use of networks of sensors or WSN (Wireless Sensor Networks) is widespread in several fields, to gather information, which can then be used by other applications. As it increases its use, it is necessary to combine or add data from sensors of different WSN, which is not always possible, due to the lack of interoperability between different manufacturers. That is why OGC (Open Geospatial Consortium) founded SWE, in order to develop standards for access to sensors via the Internet and thus improve the interoperability. For these reasons, in this thesis is specified an IoT architecture (Internet of Things) generically, so that it can be extended to multiple environments. The I3WSN architecture is designed for monitoring and control systems, ensuring interoperability between the different elements through the integration of SWE standards. After the design, the application of the architecture is carried out in three different contexts, associated with three research projects. The first of them, in order to monitor and manage the workers' health in industrial environments, based on environmental and medical data, within the project FASyS (Fabrica Absolutamente Segura y Saludable). Secondly, to ensure the level of assurance of a smart grid environment, from the capture of the security information of all its elements, in the UniverSEC project. Finally, to manage efficiently and intelligently transport freight containers, from traffic data in real time, in the project STIMULO.

Se ha desarrollado a partir de la participación en diferentes proyectos de investigación, dentro del grupo de investigación SATRD (Sistemas y Aplicaciones de Tiempo Real Distribuidos) del Departamento de Comunicaciones de la UPV. Ha pasado mucho tiempo desde la aparición de los primeros sensores que únicamente eran capaces de responder frente a un estímulo, hasta el concepto de sensor web, donde los sensores pueden ser configurados de forma remota, realizar acciones y procesar e integrar datos de otros sensores. Hoy en día, la utilización de redes de sensores o WSN (Wireless Sensor Networks) está ampliamente extendida en diversos ámbitos, para recopilar información, que luego pueda ser utilizada por otras aplicaciones. A medida que aumenta su utilización, surge la necesidad de combinar o agregar datos de sensores de distintas WSN, lo cual no siempre es posible, debido a la falta de interoperabilidad entre los distintos fabricantes. Es por ello que OGC (Open Geospatial Consortium) fundó SWE, con el fin de desarrollar estándares para el acceso a sensores a través de Internet y así mejorar la interoperabilidad.

La arquitectura I3WSN se ha diseñado para la monitorización y el control de sistemas, garantizando la interoperabilidad entre los distintos elementos gracias a la integración de los estándares de SWE. Tras el diseño, se ha llevado a cabo la aplicación de la arquitectura en tres contextos distintos, asociados a tres proyectos de investigación. El primero de ellos, con el objetivo de monitorizar y gestionar la salud de los trabajadores en entornos industriales, a partir de datos del entorno y datos médicos, dentro del proyecto FASyS (Fabrica Absolutamente Segura y Saludable). El segundo, para garantizar el nivel de aseguramiento de un entorno smart grid, a partir de la captura de la información de seguridad de todos sus elementos, en el proyecto UniverSEC. Y por último, para gestionar de forma eficiente e inteligente el transporte de contenedores de mercancías, a partir de los datos de tráfico en tiempo real, en el proyecto STIMULO.
[CAT] Aquesta tesi ha estat creada en el marc de la interoperabilitat de les xarxes de sensors en entorns industrialitzats, utilitzant l'estàndard SWE (Sensor Web capacitació). S'ha desenvolupat des de la participació en diversos projectes d'investigació, dins del grup d'investigació SATRD (Sistemes i Aplicacions de Temps Real Distribuïts) del Departament de Comunicació de la UPV. Ha passat molt temps des de l'aparició dels primers sensors que només eren capaços de respondre a un estímul, fins al concepte de sensor web, on els sensors es poden configurar remotament, realitzar accions i processar i integrar les dades d'altres sensors. Avui en dia, l'ús de xarxes de sensors o WSN (Wireless Sensor Networks) està àmpliament estesa en diversos àmbits, per a recollir informació, que desprès puga ser utilitzada per altres aplicacions. A mesura que augmenta el seu ús, sorgeix la necessitat de combinar o afegir dades de sensors de diferents WSN, que no sempre és possible, degut a la falta d'interoperabilitat entre els diferents fabricants. És per això que OGC (Open Geospatial Consortium) va fundar SWE, per desenvolupar estàndards per l'accés de sensors a Internet i així millorar la interoperabilitat. Per aquests motius, en aquesta tesi s'ha especificat una arquitectura IoT (Internet of Things) de forma genèrica, per tal que es puga estendre a múltiples entorns. L'arquitectura I3WSN s'ha dissenyat per la monitorització i el control de sistemes, garantint la interoperabilitat entre els diferents elements gràcies a la integració dels estàndards de SWE. Després el disseny, s'ha dut a terme l'aplicació de l'arquitectura en tres contextos diferents, associats amb tres projectes d'investigació. El primer d'ells, amb la finalitat de monitoritzar i gestionar la salut dels treballadors en entorns industrials, a partir de dades ambientals i dades mèdiques, dins del projecte FASyS (Fabrica Absolutamente Segura y Saludable). El segon, per garantir el nivell d'assegurament d'un entorn de smart grid, a partir de la captura de la informació de seguretat de tots els seus elements, en el projecte UniverSEC. I finalment, per gestionar de manera eficient i intel·ligent el transport de contenidors de mercaderies, a partir de les dades de trànsit en temps real, en el projecte STIMULO.

Um conceito bastante em voga atualmente e o de cidades inteligentes. Ele define um tipo de desenvolvimento urbano capaz de reduzir os impactos ambientais, melhorando os modelos atuais de acesso a recursos naturais, transportes, gestão do lixo, climatização residencial e sobretudo a gestão da energia (produção e distribuição). O massivo volume de dados produzidos por cidades inteligentes oferece uma grande oportunidade para analisar, compreender e melhorar o modo como elas funcionam e se desenvolvem. Esta explosão na quantidade de informações tem elevado a importância do aprendizado a partir de dados a um patamar extremamente elevado. Esta dissertação tem por objetivo descrever uma metodologia para aquisição e exploração de dados de um dos mais importantes pilares de cidades inteligentes: o sistema de transporte público. Como obter, armazenar e utilizar tais dados a fim de prover a todos os envolvidos, serviços telemáticos de alto valor agregado e o problema que se busca resolver neste trabalho. Cinco serviços telemáticos são propostos sob forma de prova de conceito: avaliação da cobertura da rede de transporte atual, seguida de uma proposta de novas linhas de ônibus; avaliação indireta da ocupação diária dos ônibus da cidade; cerca-eletrônica com os limites geográficos definidos pelos itinerários das linhas; serviços de alerta de velocidade e de manutenção. Os resultados são bastante coerentes e promissores, abrindo um grande leque de possíveis trabalhos futuros a serem explorados.
Smart city is a very trendy concept today. It defines a type of urban development capable of reducing environmental impacts, enhancing current models of access to natural resources, better transportation systems, waste management, residential climatization and, above all, energy management (production and distribution). The huge data volume produced by smart cities offers a great opportunity to analyze, understand and improve the way cities work and grow. This explosion in the amount of digital information has elevated the importance of learning from data to a higher level. This document aims at describing a methodology for acquiring and exploring data from one of the most important pillars of smart cities: the public transportation system. How to acquire, store and use such data in order to provide to all stakeholders telematics services with high added value is the problem that is sought to solve in this work. Five telematics services proof of concept are proposed: assessment of current network coverage followed by the proposal of some new bus lines; indirect evaluation of buses’ passengers occupation during the day; geofence with geographical boundaries according to itineraries; speed alert and maintenance reminder services. The results are very coherent and promising, opening up a wide range of possible future work to be explored.

Esta tesis estudia la distribución de ficheros en redes inalámbricas, analizando diferentes mecanismos que permiten optimizar la transmisión en términos de ancho de banda y calidad de experiencia. Concretamente, la tesis se centra en la transmisión de ficheros en canales multicast. Dicha transmisión resulta adecuada en ciertos entornos y tiene múltiples aplicaciones, algunas de las cuales se presentan en este trabajo. La tesis analiza en profundidad FLUTE (File Delivery over Unidirectional Transport), un protocolo para el envío fiable de ficheros en canales unidireccionales, y presenta algunas propuestas para mejorar la transmisión a través de dicho protocolo. En este sentido, una de las bases de este protocolo es el uso de un mecanismo llamado Tabla de Envío de Ficheros (FDT), que se utiliza para describir los contenidos transmitidos. Este trabajo analiza cómo la transmisión de la FDT afecta al funcionamiento del protocolo FLUTE, y proporciona una metodología para optimizar el envío de contenido mediante FLUTE. Por otro lado, en la transmisión de ficheros por multicast resulta esencial ofrecer un servicio fiable. Entre los distintos mecanismos utilizados por FLUTE para ofrecer fiabilidad, este trabajo analiza principalmente los códigos de corrección AL-FEC (Application Layer ¿ Forward Error Correction), los cuales añaden redundancia a la transmisión para minimizar los efectos de las pérdidas en el canal. Al respecto, esta tesis evalúa los códigos LDPC Staircase y LDPC Triangle, comparando su funcionamiento bajo diferentes condiciones de transmisión. Además, en el caso de tener un canal de retorno, una de las principales contribuciones de esta tesis es la propuesta de códigos LDPC adaptativos para servicios de descarga de ficheros. En esta clase de códigos, el servidor de contenidos cambia dinámicamente la cantidad de protección FEC proporcionada en función de las pérdidas que detectan los usuarios. La evaluación demuestra el buen funcionamiento de estos códigos en distintos entornos.

Thesis on "Intelligent Transport Systems in the Czech Republic and their use" is focused on the analysis of intelligent transport systems, particularly for road transport in the Czech Republic. The aim of my work is to summarize the information and knowledge of ITS in the Czech Republic to introduce individual systems, their functions and to assess their contribution to road safety. Based on the evaluation of telematics systems used I suggest in the final part of the ITS elements in selected urban sprawl, particularly in the Czech Budejovice.
