A administração da operação dos transportes coletivos por ônibus em São Paulo: pública ou privada?

Trata da administração direta pelo Estado (Prefeitura Municipal) do transporte coletivo em São Paulo, procurando explicar os motivos da diminuição de sua participação. Através do estudo da decadência da CMTC e crescimento das empresas particulares, no período 1948-61, busca-se esclarecer a maneira pela qual os interesses econômicos lograram determinar a ação políticas municipal, e destruir a proposta de exploração direta, com exclusividade, pela Prefeitura, através da CMTC, do serviço de transporte coletivo. O transporte coletivo nas cidades brasileiras, e particularmente na cidade de são Paulo, é feito principalmente (quando não o é exclusivamente) através do serviço de ônibus. De maneira geral o serviço de ônibus é explorado por empresas particulares que têm nessa atividade suas respectivas fontes de lucro e acumulação de capital.

Estudo sobre as políticas de transportes coletivos urbanos implementadas na Região Metropolitana de São Paulo: período 1968 a 1982

Essa dissertação tem por objetivo principal analisa a intervenção do Estado, nas suas diferentes esferas de governo, no setor dos Transportes Coletivos Urbanos, na Região Metropolitana de São Paulo,no período 1968 a 1982, à luz da abordagem histórico-estrutural. Trata-se de um estudo descritivo com hipóteses, servindo-se do método dialético-materialista-histórico, focalizando, principalmente, as atuações da Companhia Municipal de Transportes Coletivos (CMTC), da Companhia de Transporte Metropolitano de são Paulo (METRÔ), da Ferrovia Paulista S/A (FEPASA), da Rede Ferroviária Federal S/A (RFFSA), da Empresa Metropolitana de Transportes Urbanos S/A (EMTU) e da Empresa de Planejamento da Grande São Paulo S/A (EMPLASA). O esutdo procura explicitar as relações existentes entre os aspectos específicos da questão dos transportes urbanos e o cenário político brasileiro da época, mostrando que a compreensão do problema só pode ser atingida mediante das interações referidas.

Controlar custos de transporte público e sua aplicação à cidade de São Paulo

Num cenário de reclamações sobre os custos de transporte público, tanto dos usuários quanto dos governos, é importante considerar as reformas, pequenas e grandes, que podem ajudar a controlar esses custos. Ao mesmo tempo, ter um sistema de transporte público sustentável não é apenas importante para a qualidade de vida dos cidadãos, mas também para a força da economia regional. Este trabalho pretende identificar alguns sucessos em controlar custos de transporte público apresentados na literatura internacional e aplicar essas lições ao transporte público na cidade de São Paulo, representado pela SPTrans, pelo Metrô, e pela CPTM

Modelo de gerenciamento de estoques de peças de reposição para empresas de transporte urbano de passageiros

This work searches to offer a model to improve spare parts stock management for companies of urban passenger transport by bus, with the consequent progress in their maintenance management. Also known as MRO items (Maintenance, Repair and Operations), these spare parts, according their consumption and demand features, cost, criticity to operation, lead-time, quantity of suppliers, among other parameters, shouldn´t have managed their inventory like normal production items (work in process e final products), that because their features, are managed by more predictable models based, for example, in economic order quantity. In the case specifically of companies of urban passenger transport by bus, items MRO have significant importance in their assets and a bad management of these inventories can cause serious losses to company, leading it even bankrupticy business, in more severe situations which missing spare part provokes vehicles shutdown indefinitely. Given slight attention to the issue, which translates in little literature available about it when compared to that literature about normal items stocks, and due the fact that MRO items be critical to bus urban transport of passengers companies´, it is necessary, so, deepen in this theme searching to give technical and scientific subsidies to companies that work, in many times, empirically, with these so decisive inputs to their business. As a typical portfolio problem, in which there are n items, separated into critical and noncritical, while competing for the same resource, it was developed a new algorithm to aid in a better inventory management of spare parts used only in corrective maintenance (whose failures are unpredictable and random), by analyzing the cost-benefit ratio, which compares the level of service versus cost of each item. The model was tested in a company of urban passenger transport by bus from the city of Natal, who anonymously provided their real data to application in this work

Avaliação de desempenho em mercados reguladores de transporte urbano por ônibus :proposição de um modelo aplicável ao caso de Natal

Increased competition in the market of urban transport, characteristic of the Brazilian cities from years 90, has required actions of the managing agencies to ensure the universality of service, enhancing efficiency and consumer welfare. It grows in the Brazilian municipalities, the need to adopt a systematic performance evaluation in terms of management system of indicators and targets appropriate to the regulatory context, which has the purpose of evaluating the accomplishment and compliance by dealers, of the services granted during the contract period, marked by increasingly long periods. The introduction of an index operational performance in permission contracts/concession in urban buses is intended to establish a regulatory performance, giving the contract a pro-competitive feature and to allow the managing agency the systematic and continuous monitoring of the performance of the delegated service to avoid major deviations from desired performance. A performance assessment model of public transportation companies by bus, and applicable to the case of Natal is proposed. Sought to add the particularities found in the transport system in order to assess the performance of enterprises, contribute to improving the service quality to the population and enable decision-makers a detailed knowledge of the behavior of the licensees

Otimização de escalas de serviço de tripulações estudo de caso em uma empresa de transporte urbano na região metropolitana de Natal/RN

This work aims to "build" rostering urban bus crews to minimize the cost of overtime. For this purpose a mathematical model was developed based on case study in an urban transport company in the metropolitan region of Natal. This problem is usually known in the literature as the Crew Scheduling Problem (CSP) and classified as NP-hard. The mathematical programming takes into account constraints such as: completion of all trips, daily and maximum allowable range of home and / or food. We used the Xpress-MP software to implement and validate the proposed model. For the tested instances the application of the model allowed a reduction in overtime from 38% to 84%

Análise morfotectônica da Bacia do rio Santo anastácio, sp, através de parâmetros fluviomorfométricos e de registros paleossísmicos

Fluvial morphometry is method of great value regarding neotectonic analysis of extensive areas because streams, besides representing one of the main agents in the relief modeling, quickly adjust their thalwegs to even the most gentle crustal deformations. The purpose of this paper is to present the application of some morphometric techniques in the Santo Anastácio River hydrographic basin in order to identify recent tectonic deformations. Additionally, we show liquefaction structures identified in the basin and interpreted here as seismites linked to ancient earthquakes (magnitudes greater than 5). The morphometric survey includes longitudinal stream profile analysis, RDE (declivity versus stream length) index application, and the sinuosity study of the Santo Anastácio River channel. Geologic substrate comprises Cretaceous siliciclastic rocks of the Caiuá and Bauru groups, locally covered by Cenozoic sediments (alluvial plains, terrace deposits, colluvial aprons, as well as in situ regoliths). Considering that liquefaction structures affect dark clay layers of 32.340±320 year BP age (14C dating), a lower age limit for the ancient earthquake is triggered in that region. The authors believe that neotectonic understanding of the Western São Paulo State Plateau is important to the geologic and geomorphologic evolution of that landscape and to the consequent territorial planning and occupation.
