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.

Esta pesquisa tem por objetivo obter um panorama das políticas públicas urbanas em telemática ao longo da sua recente história visando sua melhor compreensão. Isto se deve principalmente à necessidade de compreender como tais políticas evoluíram ao longo do tempo e como estas vêm influenciando a sociedade como um todo e principalmente o conjunto de lugares, tais como residência, trabalho, locais de lazer e o próprio tecido urbano que esta mesma sociedade ocupa e convive. Para esse entendimento será necessário compreender a história das comunicações em sua evolução em direção às telecomunicações, à telemática e às novas tecnologias da Informação (TIC\'s) para em seguida conhecer os serviços telemáticos que são oferecidos ao usuário final. Mas, além do conhecimento da sua história e também conhecer quais são estes serviços temos que conhecer, devido à importância, à complexidade e à velocidade em que estes serviços evoluem, as políticas públicas, no nível das esferas federal e municipal, a fim de, pesquisando a evolução temporal das políticas públicas urbanas de telemática, no nosso caso dentro do município de São Paulo, perceber toda a complexidade de sua influência, já citada anteriormente, sobre a sociedade e sobre a própria cidade. / This research is intended to obtain a general view of the urban public policies in telematic along their recent history and for a better comprehension of them. That is, mainly, due to the necessity of recognizing how such policies have developed through the time and how they have been influencing the society as a whole and, mostly, the set of places, such as residence, work, leisure areas and the urban net itself, which this same society inhabits and lives with. For this, recognition will be necessary to understand the history of communication in its evolution towards the telecommunications, telematic and the new technologies of information (TIC`s) to know, afterwards, the telematic services which are offered to the final user. But besides the knowledge of its history, and also know which these services are, we have gotten to learn, due to the importance, to the complexity and to the velocity in which these services develop, the public policies at the federal and municipal level in order to, researching the time evolution of the urban public policies of telematic, in our case, inside of the municipal area of São Paulo, to perceive in all the complexity of their influence, already mentioned formerly, over the society and over the city itself.
