2. Changing the road transport for a rail transport to access a Brazilian airport
AbstractThis paper reports a study aimed to assess whether passengers would change the road transport -- whether individual transport (IT) or passenger bus transport (BT) -- for the rail transport to reach or leave the International Airport Tancredo Neves in Confins, State of Minas Gerais, Brazil. It also sought to identify the passengers’ preference betwe

3. Sensitivity analysis of bridge-track-train system to parameters of railway
Generally, Railway bridges are long structures which have different responses against different loads of train. Applied loads of train on railroad bridges are different in terms of axle loads speed, and annual passed tonnages and they have quite different dynamic behavior in comparison with road bridges. Most researches are basically focused on the quasi-sta

5. EVALUATION OF THE PRODUCTIVE EFFICIENCY OF FREIGHT RAIL LINES IN BRAZIL: AN APPLICATION OF THE DEA METHODOLOGY / AvaliaÃÃo da EficiÃncia Produtiva das Ferrovias de Carga no Brasil: uma AplicaÃÃo da Metodologia DEA
A AgÃncia Nacional de Transportes Terrestres (ANTT) acompanha o desempenho das ferrovias de carga atravÃs de diversos indicadores e verifica se as metas estabelecidas estÃo sendo cumpridas ou nÃo, investigando as causas do descumprimento. Entretanto, quando se busca os relatÃrios de avaliaÃÃo das concessÃes ferroviÃrias, nÃo consta uma investigaÃ�

6. Aplicação do método de análise de risco ao estudo do descarrilamento. / Aplication of risk analysis method to the derailment study.
This research proposes a risk analysis method applied to derailment event (characterized by the wheel overlap on the rail, which can be caused by many aspects: rail imperfections, rolling stock failures, obstacles etc and which can cause accidents, material and life loss) to increase the safety level on railway transport that actually does not present decrea

9. Potential of the rail-road intermodality in mitigating CO2 emissions : the case of São Paulo state s cargo transport sector / Potencial da intermodalidade rodo-ferroviaria na mitigação das emissões de CO2 : o caso do setor de transporte de cargas do estado de São Paulo
No ano de 2005, no Brasil, cerca de 58% das cargas foram transportadas através de rodovias, enquanto o modal ferroviário transportou apenas 26% das cargas. O desbalanceamento da matriz de transporte de cargas paulista é ainda mais crítica, pois cerca de 88,6% das cargas que circularam pelo Estado de São Paulo foram através de rodovias e apenas 9,5% atr

10. ProgramaÃÃo linear inteira aplicada no planejamento da alocaÃÃo de vagÃes de carga / Integer linear programming applyed for railroad freight wagons allocation planning
Load transportation attendance for demand is related to the process of wagon allocation that in its turn, is associated with the way by which the decision is taken. The distribution of the wagons to the shipment terminals depends on the planning and movement of the empty wagons, being the trip of the empty wagon the parcel with bigger financial impact on the

12. DEMANDA POR TRANSPORTE FERROVIÁRIO: O CASO DO TRANSPORTE DE AÇÚCAR NA MALHA FERROVIÁRIA DA REGIÃO CENTRO-SUL / DEMAND FOR RAILROAD TRANSPORTATION: TRANSPORT OF SUGAR BY RAIL IN THE CENTER-SOUTH REGION
The high cost of transportation in Brazil, according to logistics is notorius. Mainly to farming products related to commodities, this relationship is still problematic because they don´t have any extra value. Sugar, can be considered as the most important farming trend. So, rail transportation seems to be the solution in terms of competitive prices to many
