[en] RAILROAD CARGO TRANSPORTATION IN BRAZIL: CASE STUDY OF FUEL TRANSPORTATION IN SOUTH REGION / [pt] O TRANSPORTE FERROVIÁRIO DE CARGA NO BRASIL: ESTUDO DE CASO DO TRANSPORTE DE COMBUSTÍVEIS NA REGIÃO SULCLAUDIA DUMIT 24 April 2006 (has links)
[pt] Esta dissertação aborda a evolução da malha ferroviária
brasileira e o
impacto deste modal de transporte nos estoques de Diesel e
Gasolina das Bases de
Distribuição localizadas no Sul do Brasil, pertencentes a
uma importante
distribuidora de derivados de petróleo. A relevância do
estudo realizado deve-se à
aprovação da Lei 9.478 - Lei do Petróleo - que quebrou o
monopólio da Petrobras
neste setor, transferindo para as distribuidoras o
gerenciamento espacial e
volumétrico de seus estoques. Por outro lado, o estudo
contribui para o
conhecimento da incipiente malha ferroviária brasileira, a
partir da privatização
ocorrida em 1996, e tornada importante diante da crescente
necessidade de se
agregar valor, eficiência e segurança ao transporte de
combustíveis. O objetivo
deste estudo é abordar a evolução da malha ferroviária
brasileira e o impacto deste
modal de transporte nos estoques de segurança de Diesel e
Gasolina de uma
grande Distribuidora de derivados de petróleo e o
relacionamento dos custos de
transporte atrelados aos riscos e impontualidade ainda
prevalecentes no sistema
ferroviário. / [en] This thesis approaches the evolution of the Brazilian
railroad mesh and the
impact of this modal of transportation to an important
company in the supplies of
Diesel and Gasoline to the Bases of Distribution located
in the South of Brazil.
The relevance of this study is justified due to the
approval of Law 9.478 - Law of
the Oil - that broke the monopoly of Petrobras in this
sector, transferring to oil
companies the spatial and volumetric management of their
oil inventories. On the
other hand, the study contributes for the knowledge of the
incipient Brazilian
railroad mesh, privatized in 1996, and becoming
increasingly important giving the
necessity of adding value, efficiency and security to the
fuel transportation. The
objective of the present study is the evolution of
railroad mesh and the impact of
this transportation modal on Gasoline and Diesel safety
stocks handled by an
important oil company and its relationship to the costs of
transportation related to
the risks and unpunctuality still prevailing in the
railroad system.

Low volume grade crossing treatments for the Oregon high speed rail corridorZaworski, David D. 30 April 1996 (has links)
This study defines the information gathering and communication and response
needed for safety at highway-rail crossings. It examines technologies for low-cost,
high-safety treatments for low volume highway crossings of higher speed (130-200 kph) rail. Crossing closure and consolidation is a necessary first step. Existing
train control and crossing safety systems are examined. Intelligent Transportation
System technologies are examined for applicability to the information gathering,
communicating, and control functions of grade crossing safety. Guidelines are
offered for low volume crossings of the high speed rail line in Oregon. A
preliminary cost benefit analysis is presented.
Above 200kph, crossing closure or grade separation is required. In the range of
130-200 kph, ITS technologies have the potential to enhance crossing safety at
much lower cost than grade separation. A global positioning system based positive
train control system provides the train location and speed information needed for
advanced crossing control. A traffic management center can receive train and
crossing information, operate crossing systems, and grant clearance for train or
highway users through the crossing. Remote lock gates provide safety at private
crossings. Increased traveler information and four quadrant warning gates increase
motorist compliance at public crossings. At train speeds above 175 kph, barrier
gates protect rail movements. Video monitoring and detection systems provide
reliable, redundant information should a vehicle become trapped in a crossing. / Graduation date: 1996

A microsimulation analysis of highway intersections near highway-railroad grade crossingsTydlacka, Jonathan Michael 15 November 2004 (has links)
The purpose of this thesis was to perform microsimulation analyses on intersections near Highway-Railroad Grade Crossings (HRGCs) to determine if controlling mean train speed and train speed variability would improve safety and reduce delays. This research focused on three specific areas. First, average vehicle delay was examined, and this delay was compared for seven specific train speed distributions, including existing conditions. Furthermore, each distribution was associated with train detectors that were placed at the distance the fastest train could travel during the given warning time. Second, pedestrian cutoffs were investigated. These cutoffs represented an occasion when the pedestrian phases were truncated or shortened due to railroad signal preemption. Finally, vehicle emissions were analyzed using a modal emissions model. A microscopic simulation model of the Wellborn Corridor in College Station, Texas was created using VISSIM. The model was run twenty times in each train speed distribution for each of three train lengths. Average vehicle delay was collected for three intersections, and delays were compared using the Pooled t-test with a 95% confidence interval. Comparisons were made between the distributions, and generally, distributions with higher mean train speeds were associated with lower average delay, and train length was not a significant factor. Unfortunately, pedestrian cutoffs were not specifically controlled in this project; therefore, no statistical conclusions can be made with respect to the pedestrian cutoff problem. However, example cases were devised to demonstrate how these cutoffs could be avoided. In addition, vehicle emissions were examined using the vehicle data from VISSIM as inputs for CMEM (Comprehensive Modal Emissions Model). For individual vehicles, as power (defined as the product of velocity and acceleration) increased, emissions increased. When comparing emissions from different train speed distributions, few significant differences were found. However, a scenario with no train was tested, and it was shown to have significantly higher emissions than three of the distributions with trains. Ultimately, this thesis shows that average vehicle delay and vehicle emissions could be lowered by specific train speed distributions. Also, work could be done to investigate the pedestrian cutoff problem.
