Architecture & the commute : a railway station in MamelodiTanzarella, Beatrice 30 November 2012 (has links)
This dissertation investigates architecture's potential role in improving the experience of the daily commute into and out of the city. It is proposed that an architectural intervention that takes into account the 'embodied' experience of the commuter as key informant could assist in such an improvement. Various structural and infrastructural upgrades are being planned for the east-west Metrorail link between Pretoria Station and Mamelodi by the Tshwane Municipal Government and the Passenger Rail Agency of South Africa (PRASA). This link is selected to act as setting for the enquiry, with Mamelodi Gardens Metrorail Station as site for architectural intervention. A conflict is identified between requirements of the public transport system to function optimally and efficiently and the experiential and everyday needs of the commuter who encounters it. The dissertation aims to relieve this apparent opposition through a design process of mediation. Due partially to its functionally driven nature, public transport planning often leads to an environment of extremes which places the commuting experience under tension. Architecture's potential role in alleviating these extremes through impact or through the mediation of other environmental impacts is explored. Phenomenological philosophy, as a study based in the ontological enquiry of conscious experience, is the theoretical stimulus to the experiential component of the study. This theoretical base is partnered with investigative and interpretive study in order to ascertain the various ways in which architecture could potentially impact on the embodied experience of the commuter. / Dissertation MArch(Prof)--University of Pretoria, 2012. / Architecture / MArch(Prof) / Unrestricted

Market feasibility analysis of the Martin Luther King, Jr. Station Transit Oriented Development ZoneAshby, Michael David 25 November 2013 (has links)
The area surrounding Capital Metro’s Martin Luther King, Jr. (MLK) MetroRail Station was designated a Transit-Oriented Development (TOD) zone and a plan was published in 2009. However, to date there has been very little development, and the development that has occurred is significantly different from what is called for by the plan. This report examines some of the difficulties of implementing TOD in Austin and the factors that could contribute to successful TOD projects. A market analysis of the MLK Station Area explores the economic feasibility of developing land there to its highest and best use. It concludes that the general dearth of TOD in Austin and lack of dense, mixed-use development in the MLK neighborhood make the kind of development called for in the MLK Station Area Plan excessively risky for developers. However, a more conventional multifamily development would be feasible, and increased station-area density could contribute to the success of future TOD. / text

Towards urban multilingualism: investigating the linguistic landscape of the public rail transport system in the Western CapeJohnson, Ian Lyndon January 2012 (has links)
Magister Artium - MA / This study explores the linguistic landscape of Metrorail in the Western Cape, South
Africa. The Western Cape is a diverse, multicultural society with a history of
colonialism and imperialism. For this reason, the language/s on signage was explored to reveal differences/similarities between the various groups and cultures within society.This kind of investigation entailed consideration of the signage displayed on trains,stations and other railway infrastructure. Thus, data was collected over a three-month period during 2010 which coincided with the FIFA Soccer World Cup, hosted by South Africa. A combined quantitative and qualitative approach for the analysis of data was supplemented with a multimodal, multi-semiotic approach. In addition, interviews were conducted of a cross-section of commuters as a way to give meaning to the analysis of the quantitative and qualitative data. The analysis explored the extent to which multilingualism and multiculturalism are reflected in the linguistic landscape of Metrorail.The focus of the study was on the degree of visibility of the official and non-official languages on signage, as faced by Metrorail commuters. The findings of the study reveal
that the interplay between power relations, prestige, symbolic value, identity and vitality in the linguistic landscape of Metrorail results in a somewhat limited display of multilingualism. The findings also reflect the changed language attitudes and
perceptions, the maintenance of power relations, the expression of identity, and the
desire to be perceived in a certain way, in a broader South African context. Furthermore,the data reveals that the actual linguistic reality does not accurately reflect the aims of the Western Cape language policy in terms of promoting multilingualism. Moreover, it reveals that English is the preferred language of wider communication and it is also the dominant language on the official and non-official signage in the public space. Although the indigenous African languages, along with Afrikaans, are generally neglected in the public space, these languages are widely spoken by Metrorail commuters. The linguistic landscape of Metrorail therefore does not accurately reflect the linguistic reality of the various speech communities in the Western Cape. The linguistic landscape of Metrorail serves to index the broader social developments of the transformed sociolinguistic South African identity.

The recommendation and validation of an appropriate physical asset management policy for Prasa’s Metrorail divisionRommelspacher, Karl Otto 03 1900 (has links)
Thesis (MScEng)--Stellenbosch University / ENGLISH ABSTRACT: The
decline
of
the
passenger
rail
transport
system
of
South
Africa
over
the
past
two
decades
has
left
the
passenger
rail
industry
in
a
difficult
position.
The
most
significant
impact
has
been
the
deterioration
of
the
physical
assets.
Due
to
the
renewed
focus
by
government
on
passenger
rail
transport,
the
need
for
improving
the
physical
asset
management
has
been
recognised.
Physical
asset
management
manifests
itself
through
the
application
of
strategies.
The
need
for
new
and/or
updated
strategies
was
identified
and
summarily
examined.
Through
the
initial
literature
study,
it
was
found
that
strategies
are
founded
on
the
specific
maintenance
policy
of
an
organisation.
The
application
of
the
new/updated
strategies
was
intended
to
take
place
at
Metrorail.
An
investigation
at
Metrorail
revealed
the
lack
of
any
significant
policy
that
is
required
to
develop
any
new
strategies.
This
discovery
led
to
a
shift
in
focus
from
the
development
of
new
strategies
to
the
development
of
a
physical
asset
management
policy.
A
generic
policy
statement
called
Requirement-‐based
Asset
Management
(RAM)
was
developed,
with
its
primary
focus
being
the
conducting
of
maintenance
activities
based
on
the
requirements
of
the
organisation,
the
employees,
the
asset
and
the
customer.
In
order
to
evaluate
the
suitability
of
RAM,
a
strategic
roadmap
was
developed
based
on
the
policy
statement
and
validated
in
three
areas
of
Metrorail.
These
three
areas
were
the
wheel
set
maintenance
system,
the
Top
7
fault
evaluation
procedure
and
the
scheduled
maintenance
cycle
of
the
train
sets.
The
application
procedure
concluded
that
the
roadmap
and
thus
by
deduction
RAM
are
suitable
for
the
Metrorail
environment.
RAM
can
be
used
to
develop/improve
an
organisation’s
physical
asset
management
policy. / AFRIKAANSE OPSOMMING: Die
agteruitgang
van
die
vervoerspoorwegstelsel
vir
passasiers
gedurende
die
afgelope
twee
dekades
in
Suid-‐Afrika
het
hierdie
bedryf
in
‘n
moeilike
posisie
geplaas.
Die
mees
beduidende
impak
van
hierdie
verwaarlosing
is
die
agteruitgang
van
die
instandhouding
van

Die
regering
se
hernuwe
fokus
op
die
vervoer
van
passasiers
per
spoor
het
gelei
tot
die
herkenning
van
die
behoefte
aan
verbeterde
bestuur
van
fisiese
bates.
Die
bestuur
van
fisiese
bates
word
gemanifesteer
deur
die
toepassing
van
strategieë.
‘n
Behoefte
aan
nuwe
en/of
opgedateerde
strategieë
is
geïdentifiseer
en
nagevors.
Die
aanvanklike
literatuurstudie
het
bevind
dat
strategieë
op
‘n
organisasie
se
spesifieke
instandhoudingsbeleid
gebaseer
is
en
die
toepassing
van
hierdie
nuwe
en/of
opgedateerde
strategieë
is
beplan
by
Metrorail.
‘n
Gebrek
aan
‘n
noemenswaardige
beleid
wat
vereis
word
vir
die
ontwikkeling
van
nuwe
strategieë
is
by
Metrorail
gevind.
Hierdie
bevinding
het
‘n
fokusverskuiwing
tot
gevolg
gehad
–
van
die
ontwikkeling
van
nuwe
strategieë
na
die
ontwikkeling
van
‘n
bestuursbeleid
vir
fisiese
bates.
‘n
Generiese
beleidsverklaring
genaamd
“Requirement-‐based
Asset
Management”
(RAM),
met
die
primêre
fokus
op
instandhoudingsaktiwiteite,
is
ontwikkel
en
is
gebaseer
op
die
behoeftes
van
die
organisasie,
die
werknemers,
bates
en
kliënte.
‘n
Strategiese
metodologie
wat
op
die
beleidsverklaring
gebaseer
is,
is
ontwikkel
om
die
geskiktheid
van
die
RAM
te
evalueer
en
is
dit
in
drie
areas
van
Metrorail
gevalideer.
Hierdie
drie
areas
sluit
in
die
instandhoudingstelsel
vir
wielstelle,
die
prosedures
betrokke
by
die
evaluasie
van
die
sewe
mees
beduidende
foute,
en
die
geskeduleerde
instandhoudingsiklus
van
die
treinstelle.
Deur
die
toepassingsprosedure
is
die
gevolgtrekking
gemaak
dat
die
metodologie,
en
gevolglik
die
RAM,
geskik
is
vir
die
Metrorail-‐omgewing.
Die
RAM
kan
dus
gebruik
word
vir
die
ontwikkeling
en/of
verbetering
van
‘n
organisasie
se
bestuursbeleid
vir
fisiese
bates.

A decision support model to improve rolling stock maintenance scheduling based on reliability and costAsekun, Olabanji Olumuyiwa 12 1900 (has links)
Thesis (MEng)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: The demand for rail travel has increased over the years. As a result, it is becoming mandatory for railway industries to maintain very high availability of their assets to ensure that service levels are high. Railway industries require both their infrastructure and rolling stock assets maintained efficiently to sustain reliability. There has been on-going research on how maintenance can be carried out in a cost effective manner. However, the majority of this research has been done for infrastructure and the rolling stock maintenance has not been properly covered.
The purpose of this research is to contribute to the maintenance sector of rolling stock for railway industries by developing a decision support model for rolling stock based on reliability and cost. The model is developed as an optimization problem of a system containing several components dependent on each other with different reliability characteristics. In this model, a mixed integer nonlinear problem is developed and solved using an exact method and metaheuristics methods. The Metrorail facility in Cape Town was chosen as a case study. Failure history and cost data were gathered from the facility and the information was applied to the model developed. The case study was investigated and different results were achieved using both exact and metaheuristics methods.
The final result from the study is an optimal maintenance schedule based on reliability and cost. The developed model serves as a practical tool railway companies can adopt to schedule rolling stock maintenance to achieve a high level of reliability and at the same time maintaining minimum cost expenditure. / AFRIKAANSE OPSOMMING: Die vraag na spoorvervoer het oor die jare toegeneem. Dus het dit belangrik geword dat die spoorweg se bates hoogs toeganklik moet wees om te verseker dat die vlak van dienslewering hoog bly. Die spoorweg industrie besef dat hulle infrastruktuur, lokomotiewe, waens ens. effektief in stand gehou moet word sodat dit betroubaar kan wees. Navorsing word nog steeds gedoen oor hoe instandhouding op ’n koste-effektiewe wyse gedoen kan word. Die meeste van hierdie navorsing gaan egter oor infrastruktuur en instandhouding word nie ordentlik gedek nie.
Die doel met hierdie navorsing is om by te dra tot die instandhoudingsektor van die spoorweg deur om ’n besluit-ondersteunende model vir lokomotiewe, waens, ens wat op betroubaarheid en koste gegrond is, te ontwikkel. Die model is ontwikkel as ’n optimasie probleem van ’n sisteem wat verskillende komponente wat van mekaar afhanklik is maar oor verskillende betroubaarheidskenmerke beskik, inluit. In hierdie model word ’n gemengde, heeltal nie-lineêre probleem ontwikkel en met ’n eksakte metode en metaheuristiese metodes opgelos. Die Metrorail fasiliteit in Kaapstad is vir die gevalle studie gekies. Die geskiedenis van mislukkings en koste data is by die fasiliteit versamel en die inligting is op die model wat ontwikkel is, toegepas. Die gevalle studie is ondersoek, en verskillende resultate is met eksakte en metaheuristiese metodes bereik.
Die finale uitkomste van die studie is ’n optimale instandhoudingskedule wat op betroubaarheid en koste gegrond is. Die model wat ontwikkel is dien as ’n praktiese instrument wat spoormaatskappye kan gebruik om die instandhouding van lokomotiewe, waens ens. te reël sodat ’n hoë vlak van betroubaarheid bereik kan word en kostes terselfdertyd tot ’n minimum beperk kan word.
