Um Estudo de Politicas e Práticas do uso do GNV no transporte público urbano do Brasil

The use of Natural Gas Vehicle has had a fast increase lately. However, in order to have a continuous success this Program needs to develop converting devices of Otto-cycle engines, gasoline or alcohol, to the use of NGV (Natural Gas Vehicle) that presents low cost, maintaining the same original development of the vehicle and low level of emissions, considering the PROCONVE rules. Due to the need to diversify the matrix in order to avoid energetic dependence and due to strict pollution control, it has increased in the Brazilian market the number of vehicles converted to the use of NGV. The recent regulation of the PROCONVE, determining that the converted engines with kits should be submitted to emission testing, comes to reinforce the necessity of the proposed development. Therefore, if we can obtain kits with the characteristics already described, we can reach a major trust in the market and obtain an increase acceptance of the vehicle conversion for NGV. The use of natural gas as vehicle fuel presents several advantages in relation to liquid fuels. It is a vehicle fuel with fewer indexes of emissions when compared to diesel; their combustion gases are less harmful, with a major level of safety than liquid fuels and the market price is quite competitive. The preoccupation that emerges, and the motivation of this project, is to know which are the main justifications for such technology, well accepted in other countries, with a low index or emission, with a high level of safety, where its maintenance becomes low, reminding that for this it is necessary that this technology has to be used properly, and once available in the market will not motivate interest in the urban transportation companies in Brazil, in research centers in general. Therefore this project exists to show the society in a general way the current vision of the main governmental factors, of the national research centers and of the private companies concerning the use of natural gas vehicles in urban transport vehicles, in order to give a major reliability to the population as well as to motivate national market competitiveness with a low cost and reliable product and to enrich the national technology

Uma aplicação de análise de decisão com o método AHP Processo de hierarquia analítica: um estudo sobre adoção de Sistema eletrônico de cobrança no Transporte público urbano

This thesis carries through an application of Analysis of Multicriterion Decision with use of the method of Analytical Hierarchy Process (AHP) in the problematic one of taking of decision of the adoption of electronic collecting in the system of urban transport in the country, a subject that has been controversial. A modeling of criteria and alternatives is carried through and applied a questionnaire based on method AHP the excellent actors in the system of urban transport - Leading of the Managing Agency Public Municipal theatre of Urban Transports, Controller of Company of Bus, Controller of Labor union, Controller of Union of Companies, Communitarian Leader. The considered alternatives were: the maintenance of the current state with collectors, the implementation of electronic collection without collectors, and the implementation of electronic collection with collectors. The used criteria were: job, impact in the fare, control of the system, easiness of use, information. The study was carried through in the city of Natal, RN, where if the adoption of electronic collection argues and where this implementation in some bus lines between Natal and Parnamirim exists, city that integrates the region of the great Natal. The main results of the method evidence in a dimension, the viability of use of method AHP with questionnaire by means of validation of the judgments with analysis of variance beyond proper the normal mechanisms of analysis of consistency to the method, and in another one, the contribution of the analysis boarding multicriterion to become the judgments more clearly. The main results of the analysis help to show that although to models of criteria and distinct judgments of the actors, the method evidenced that it has inclination the adoption of the electronic collection on the current situation, even so with divergences between the maintenance or not of the collector. The research points to the possibility of accomplishment of the application of the AHP in successive rounds of judgments

Um sonho distante: reflexões sobre acessibilidade nos conjuntos habitacionais do pmcmv faixa 1 na região metropolitana de Natal

This dissertation seeks to reflect on the accessibility of the governmental program Minha Casa Minha Vida, track 1, which comprehends people who made 0 to 3 minimum wages within the metropolitan region of Natal RN between the years of 2009 and 2012. The research covers the municipalities benefited by the program: Ceará-Mirim, Extremoz, Macaíba, Monte Alegre, Natal, Nísia Floresta, Parnamirim and São Gonçalo do Amarante. We have investigated the extensions of PMCMV on the context of the access to the city, debating some concepts attached to the capitalist mode of production such as residential segregation and peripherization. We have aimed to identify the accessibility conditions in the new housing complexes from three primal categories, namely, the localization of the complexes, the disponibility of public equipments, services, leisure and cultural properties on the neighborhood and the offer of public transport. Our theorical references are based on the ideas of the british geographer David Harvey on his work Social Justice and the City , from 1980. Harvey s studies made us debate on the locational choice for the social-matter habitation, and also let us discuss the price to accessibility on these new programs and its implications on the income of those who are benefited by them, specially because this is about a low-income population. To the achievement of these objectives, we made use of case study, including desk research, photographic documentation, records of field observations and informal conversations with locals, composing a qualitative study. In light of what has been researched and considering the guiding research questions, we reflect on aspects of the program that can greatly influence the processes of residential segregation and housing periphery of the lowincome population from the precarious conditions of accessibility to the referred population

As fontes de desgaste físico e emocional e a Síndrome de Burnout no setor de transporte coletivo urbano de Natal

Recognizing the importance the workplace has on mental health of the individual, the objective of this study was to investigate the relationship between the burnout syndrome and the sources of physical and emotional wear which permeate the work conditions of the urban public transport system of the city of Natal. Although existent in international literature, research on burnout in the professional transport category and studies directed to this category are not a tradition in Brazil. The research was carried out using 412 drivers and money-changers of two transport companies of Natal. To collect the data, two questionnaires and a semi-structured interview were used. The first instrument, developed and validated during the research, investigated the sources of wear and the second, the syndrome of burnout. As its main results, two sources of empirical wear were identified as follows: (1) the Conflict of Values and the Lack of Justice at the Workplace, (2) Union and Reward. Besides these, it was observed that there is an incidence of the syndrome of burnout among the drivers and money-changers of urban transport by bus, not only in the caring occupations studied before in Natal and Brazil and that this incidence is related to the sources of wear which permeate the work conditions of these professionals
