Communication is a vital part of any research. We communicate to form research
collaborations, to gain funding, to have our findings reviewed, and to share our
results with our peers and the wider community. Research conferences often offer
the opportunity to communicate via poster presentations. A well structured,
informative and attractive poster can be very effective at capturing the
imagination of other researchers. In addition, developing a poster involves
selecting your best research, and using efficient words and ideas to reduce this
research to only a few hundred words. The process therefore helps the student
focus on what is really important in any study. Hence, preparing and presenting a
poster is a vital skill for all postgraduate students, and indeed for all researchers.
As part of its postgraduate program the School of Natural and Built Environments
holds an annual poster presentation for research students to develop the poster
construction and presentation skills that will help them develop as researchers
and in their future careers. The School has a diverse array of students from
Australia and around the world and the research conducted falls within a number
of academic disciplines.
The gathering together of these students to present and discuss their work has
many benefits. First, they must succinctly portray a quantum of their work. In
itself, this process is an important skill and one that can only be honed with
practice and feedback. Second, the discussion of their project with other
researchers often leads to new insights, new directions, or new collaborations.
This speculation is of great benefit to all involved. Third, the research students
must consider the work of their peers. This consideration can lead to new ideas
for their own projects – new ways to view or collect data, new methods of
analysis, or new ways to present results. Fourth, research gatherings lead to

meetings and friendships that can provide support through a research student’s
degree and beyond. These events are a welcome addition to the opportunities for
School staff and students to share their research. The diversity of the School
ensures that these events are a fascinating and stimulating gathering of
personalities and research.
I am continually impressed by the quality of work conducted and presented by the
research students within the School of Natural and Built Environments. The
posters presented in this document are a great example of both the breadth of
research conducted at the School and its quality. I thank the research students for
again rising beyond what is expected of them and ensuring the success of this
forum. This success is one that benefits both the students and the School as a
vibrant research culture that continues to grow.

About the School
The School of Natural and Built Environments focuses on the unique relationships and
synergies between natural and built environments, with a particular interest in teaching and
research to support improved environmental and socio‐economic sustainability for the future.
The School is located across two campuses – in the heart of Adelaide at the City East Campus
and at the expanding and vibrant new suburb of Mawson Lakes on the northern fringe of the
City. As part of the Division of Information Technology, Engineering and the Environment (ITEE),
the School offers applied and relevant programs that take students out of the classroom and
into the field.
Civil Engineering
Civil Engineering programs place particular emphasis on the application of theory through
focused project and assignment work. By the final year of the degrees, fifty per cent of the
courses are project based including a major industry related research project and a design
project that models industry experience. This strong industry focus ensures that graduates are
already familiar with the industry needs and modes of operation when they commence
employment. The programs are accredited by Engineers Australia. Industry links include
Department of Transport, Energy & Infrastructure (DTEI), SA Water and Built Environs ‐ all of
whom provide scholarships for students in the program. UniSA coordinate regular industry
lectures as well as industry sponsored student projects.
Construction Management and Economics
Construction Management and Economics at UniSA offers the only construction management
degrees in South Australia and is one of the most accredited construction management and
economics programs in Australia. Students can study a broad range of courses, including the
study of sophisticated construction techniques, surveying and estimating, design economics,
contract administration, project management, planning and more. All undergraduate and
postgraduate programs provide the education and training required to reach a professional
level and have a number of key industry links. The Bachelor of Construction Management and
Economics program maintains a 100% employment rate.
vii
Environmental Management and Sustainability
UniSA offers four specialised programs in the field of Environmental Management and
Sustainability ‐ Biodiversity and Park Management, Environmental Protection and Management,
Geospatial Information Systems, and Geographical and Earth Systems. All four awards provide
students with a broad understanding of environmental issues and share a common first year,
allowing the flexibility to move between the awards as career aspirations become clear.
Graduates will be qualified to work in a wide variety of positions related to the natural and built
environment and the multi‐disciplinary nature of the programs, as well as the strong focus on
practical components of learning and active fieldwork, provides expertise in the natural, spatial
and social sciences. Graduates are employed in the private and government sector in all
Australian states and several overseas countries.
Transport Systems Engineering
The Transport Systems Engineering program is designed to provide Masters level expertise in
the planning, designing and managing of transport systems and continuing education for
graduate students with professional interest in the area of transport systems engineering and
transport planning. The coursework enhances the concepts and theory in different aspects of
traffic and transport engineering and students develop the capacity to undertake independent
research and the ability to analyse and report on research procedures and findings.
Urban and Regional Planning
Urban and Regional Planning at UniSA is home to the longest‐established planning school in
Australia and celebrates sixty years of planning education in 2009. Both the undergraduate and
postgraduate programs incorporate a range of teaching techniques focused on providing
students with the best possible conditions to advance their learning. Students undertake field
trips, engage in collaborative projects, and are taught a number of professional skills courses by
highly qualified planners. A work placement program has been built into the bachelors degree
which provides students with an opportunity to work alongside qualified planners for an
extended period of time. The Planning programs are strongly supported by the Planning
Institute of Australia, the national body that accredits professional planners. There is also a
strong ‘Young Planners’ group, which represents recent graduates and is closely linked to the
student‐governed ‘Organisation of Planning Students’.

Abstract:The 36Cl and 14C ages of a given groundwater sample are often quite different. The 36Cl ages may be up to one order of magnitude higher than the 14C ages. The problem is global and can be attributed either to using inaccurate initial 36Cl and 14C values or to applying inaccurate in-aquifer 36Cl and/or 14C evolution model/s. This work, for the first time, presents similar 36Cl and 14C ages for Great Artesian Basin (GAB) groundwater at Dalhousie, South Australia, using initial 36Cl and 14C values from the recharge area and assuming subsurface addition of 36Cl-free Cl .
Figure 1 Proposed 36Cl/Cl evolution models in the southwestern Great Ar-tesian Basin.
U. A. Abu Risha School of Natural & Built Environment, The University of South Australia
The majority of previous studies attrib-ute the evolution of groundwater initial 36Cl/Cl ratios to: 1. the decay of the initial 36Cl, and2. the transfer of hypogenic 36Cl into
groundwater from aquifer rocks.Three models were found to account for the evolution of the assumed 36Cl/Cl initial ratios measured in the Sandy and Claude wells which occur in the GAB recharge area, to the ratios ob-served in the Dalhousie Springs within times similar to the 14C ages (Figure 1). The Sandy well model assumes subsurface 36Cl-free Cl addition to the groundwater at a rate of 5 mg/l/ka (1000 years). The Claude well models assume subsurface 36Cl-free Cl addi-tion rates of 5 and 10 mg/l/ka.
Figure 5 Comparison between the 14Cages and the 36Cl ages estimated assum-ing initial 36Cl/Cl ratio similar to the Claude well ratio and subsurface 36Cl-freeCl addition rates of 5 & 10 mg/l/ka.
The differences between the esti-mated 14C and 36Cl ages are < 5 ka (Figures 4 and 5) which can be re-garded as a breakthrough in ground-water dating studies.The atmospheric 36Cl/Cl ratios can-not represent the initial groundwater ratio because they are: (1) quite dif-ferent from the recharge area groundwater ratios. and (2) widely variable both spatially and temporally (Keywood, 1995). The ratios of the Claude and Sandy wells are similar to the ratios of the Finke River flood-water (Radke et al. 2000).
Figure 2 14C ages-36Cl/Cl ratio plots of the Dalhousie Springs in the evo-lution time space of the initial 36Cl/Clratio measured in the Claude well as-suming subsurface 36Cl-free Cl rates of 5, 10, and 20 mg/l/ka.
To link the 14C ages to the 36Cl/Cl evo-lution models, the14C ages were plot-ted versus the measured 36Cl/Cl ratios on the initial 36Cl/Cl evolution plots (Figure 2 and 3). It is clear that the Sandy model assuming subsurface 36Cl-free Cl addition rate of 5 mg/l/ka is better than the other models and its ages are closer to the 14C ages. This method provides a means to check the validity of the assumed 36Cl-free Cl ad-dition rates. The actual addition rates to the samples plot to the right of a given model curve are less than the assumed rate of this model whereas the addition rates of the samples plot to the left of the curves are higher than the assumed rates.
Figure 2 14C ages-36Cl/Cl ratio plots of the Dalhousie Springs in the evolu-tion time space of the initial 36Cl/Clratio measured in the Sandy well as-suming subsurface 36Cl-free Cl rates of 5 and 10 mg/l/ka.

Figure 4 Comparison between the 14Cages and the 36Cl ages estimated assum-ing initial 36Cl/Cl ratio similar to the Sandy well ratio and subsurface 36Cl-free Cl addi-tion rate of 5 mg/l/ka.
Conclusions14C and 36Cl are natural radioactive isotopes. After entering an aquifer, they start to decay. If the initial 36Cl/Cl ratio decline is only due to decay, it cannot be measured before the pas-sage of 60 ka. By then all the initial 14C is ex-pected to be decayed. However, this condi-tion is rare in nature and the addition of 36Cl-free Cl or mixing with old saline groundwater can cause 36Cl/Cl measurable differences within the limits of the 14C ages.

RecommendationsThe atmospheric chemical deposition studies in Central Australia focused only on the rain-fall events of normal magnitudes (e.g. Hutton, 1986; Keywood, 1995). The develop-ment of freshwater bodies below the ephem-eral rivers in the GAB reflects the need for studying floodwater chemistry in this region.

6. Research theoretical frameworkThis research employs communicative planning theory to draws on Haber-mas’ theory to engage Af-rican migrants in a discus-sion of their experiences & their interpretations of housing conditions in re-lation to bureaucratic de-
cisions & how com-municative tensions might affect them.My aim is to seek a consensus on how best to address ten-sions between or-ganisations that me-diate between Afri-can migrants & af-fordable housing &
1. Aim and objective of the re-search
The research’s major aim and objec-tive is to empirically explore the housing related issues that could present themselves through data collected from African migrants. The research identifies & examinesThe challenges by drawing onCommunicative action theory.
4. Literature review Many of African migrants arrived in Australia as part of the federal government humanitarian pro-gram in response to political crisis & civil wars in Africa. Before reaching Australia, many of them spent several years in refugee camps after fleeing their countries of origin. The housing crisis in the African community is the result of many factors. Among these are issues with obtaining paid work.
2. Research limitationsLiterature & studies of African refugees have focused on health & education issues with modest focus on how housing issues matter for durable settlement of Africans, or the relationship of housing to health & education. This research will add to exist-ing literature and academic knowledge es-pecially in the field of urban & regional
Housing pathways and community integration of African refugees in Australia: Towards an understanding of African refugee housing issues
African families traditionally live in an extended familysituation. They need an affordable home for successful settlement and integration in Australia. New housing stocks are required to meet the housing needs of African migrants as much of current housing stock in Australia do not suit large families.
Map indicates patterns of African migration to South Australia over recent
3. The significance of the researchThis research serves two functions, i.e. to contribute to the existingrefugee migration field of studies & to address limitation of housingliterature particularly in relation to African refugees in Australia. It aims to provide conclusions & recommen-dations that will be based on sound research findings.
5. Research methodologyIn order to effectively investigate the housing experiences of the African refu-gees in Australia this research under-takes a case study of African refugees in Adelaide, South Australia. In-depth semi-structured interviews will be the primary means of data collection. The case study will involve 20 semi-structured interviews with purposively selected African migrants from refugee backgrounds.
7. Results and discussionData analysis focuses upon two key areas: housing needs as an indicator to community integration & demand, and other social problems confronting African migrants in the wider Australian society. It discusses the nature of household demand specifically in relation to family structure and household size. The analysis will pay particular attention to economic andsocial capital. Close examination of such factors will offer effective understanding of African migrants’ housing situation in the context of Australian social policy.

RESULT AND RECOMMENDATION
The aim
of this research is to explore urban green spaces and people’s attitudes
toward wildlife in Kuala Lumpur,
Malaysia and to compare this to the scenario in Adelaide,
South Australia.
Focus Groups :
NGOs and Built
Environment Professionals
1) Open space planning In Malaysia, urban green space has received little atten-tion in future planning. Large cities such as Kuala Lum-pur aim ambitiously to be a ‘Garden City’ by 2020 (Draft KLSP 2020). However, urban green space planning has been implemented to fulfil predominantly the social needs of people and less consideration to environmental aspects such as wildlife and biodiversity, woodlands and wetlands.
2) Urban green space conservation Urban green space is decreasing due to pressures of rapid population growth, residential and commercial de-velopments. If this trend continues it will invariably af-fect the health and sustainability of the urban environ-ment and lead to long-term damage of the natural habi-tat (Pauleit 2003, Tratalos 2007 and McKinney 2008). Due to the decline in the amount of urban green space many problems occur such as floods, air and noise pol-lution and social and health issues.
3) Demand on Urban Green Space literature
There are not many published scientific researches re-lating to environmental matters of urban green space. For example, in the last sixteen years these issues were not highlighted in the Journal of Landscape and Urban Planning (Chiesura 2004; Matsuoka & Kaplan 2008).This shows that little intension and contribution by profes-sional on the environmental issues, (Brown 2005). How-ever, Swanwick et al (2003) and Bell et al (2007) argue that it has been addressed in other studies, particularly those emanating from the UK.
4) Attitude on Urban green space
Urban green space is crucial to sustainable city because it involves social, economic and environmental issues and if managed properly, has ecological benefits for its inhabitants. Professionals and other citizens are well aware of the values of urban green space and its promo-tion of social integration, community development and environmental protection (Swanwick 2003 and Balram 2005). However, many countries currently have little knowledge about environment conservation (Niemela 1999) and there is little understanding or agreement of this concept among built environment professionals (Brown 2005).

1. To identify the perception of the stakeholder and citi-
zens regarding on the social and environmental bene-
fits of various urban green spaces.
2. To recognize the perceptions/attitudes of stakeholders
and public toward wildlife in urban green spaces.
3. To explore why do ecological con-
cerns of urban green space receive
little intention from citizens and
stakeholders?
CONCLUSION
This research will investigate perceptions of various stakeholders and urban dwellers in Kuala Lumpur, Ma-laysia and Adelaide, Australia. It will make a comparison of both cities’ policies regarding urban open spaces and their implications for urban policy development. Both cities are aware that it is important in an era of increas-ing urbanization to provide more peaceful and sustain-able urban environments. Guidelines will be suggested for making attainable urban open space and more gen-erally in improving people’s knowledge of the environ-ments they live in.

Clues from the past witha view to the future
M.N. Binnie, School of Natural and Built Environments, University of South Australia, Mawson Lakes, SA 5095
IntroductionUnderstanding modern environments provides
information that may enable interpretation of ancient
environments. For example, investigating signals of the
past may contribute to a better understanding of Earth
and current climate change. This in turn, may allow
predictions of future sea-level changes. Foraminifera are
potentially useful tools for such investigations.
PurposeAspects of this research was designed to:
�� Investigate the distribution pattern of modern foraminifera
in an estuarine environment.
�� Determine the species of foraminifera that have potential
for use as indicators of euryhaline conditions, that is, able
to tolerate a broad range of salinity.
Results from this project will provide additional data on the
distribution of benthic foraminifera in modern environments
and broaden the main investigation into ancient sea-levels in
Spencer Gulf, South Australia.
Foraminifera are single celled organisms which construct shell-like
tests (Figs. 3 & 4). They predominantly occur in marine
environments, from estuaries to open oceans and also in saline
lakes. Species distribution is related to water depth, which is a
primary factor that controls such parameters as salinity,
temperature, dissolved gases, light and plant distribution. Their
wide, geographical distribution and abundance makes them ideal
proxies for palaeo-environment analysis and interpretations.
Study Site Onkaparinga Estuary (Fig. 1) is situated approximately 35
km south of Adelaide and consists of a tidal channel with
adjacent tidal flats, salt marshes, artificial wetlands and
open water. The estuary is 10.5 km long and extends from
Old Noarlunga to the mouth (Fig. 2) at Port Noarlunga (DEH
2005). It is a tidal dominated, open estuary and is host to a
variety of birdlife, invertebrates and fishes.

Discussion & Conclusion Estuarine parameters are variable. For example, salinity can
reach to levels greater than 37 ‰ in the upper reaches
depending on seasonality and daily tidal influences. Species
such as E. excavatum are tolerant to and exploit such
conditions, hence dominate the foraminiferal assemblage.
These same species that are present in modern estuaries
are also preserved as fossils in sediment cores thus
providing clues to past environments.
Fig. 6 Selected pie diagrams illustrating dominant species; upper estuary.
ResultsSurficial sediment samples were taken from 8 sites along
the estuary. Preliminary results indicate low species
diversity in the upper estuary (Fig. 5) where it is
dominated by Elphidium excavatum and Ammonia beccarii
(Fig. 6). In contrast, species diversity is greatest in the
lower regions closer to the estuary mouth.

Method 1: Using the principles of Participatory GIS and Continuous Improvement, construct a value stream to determine theeffectiveness of GIS within ILC business processes and constituent parts, then communicate the results to the ILC
NB The communication is a work in progress. Below is a template that will be used to convey the efficiency savings to the
ILC. The final version of the template will be an interactive poster where ILC personnel will be allowed to
navigate to relevant information by clicking on the different tabs & buttons, including videos to compare current business
processes against proposed GIS orientated processes.
Aim 1:Contribute to the ILC’s land acquisition and land management processes by identifying opportunities to increase the
application of GIS and methodologies as a means of maximising benefits for Indigenous people.

Barriers to Local Governments’ Action to address Climate Change
Climate Change and Local Governments
The issue of climate change and the need to reduce emissions of greenhouse gases (GHGs) has in recent years become a key area of concern for communities in Australia. The Intergovernmental Panel on Climate Change (IPCC 2007) reported that
“the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations and that discernible human influences now extend to other aspects of climate including ocean warming,
continental-average temperatures, temperature extremes and wind patterns.” Although climate change is a global issue the contributing factors arise through local action, particularly the use of energy from fossil fuels. While state planning strategies dictate the direction and priorities for planning communities into the future, these are then incorporated into development plans and policies for implementation by each local government agency. Australian local government is the statutory body primarily responsible for jurisdictional planning decisions and shaping the future character of the local built and natural environments (Critchley and Scott 2005).
‘Ideal’ Local Action
A questionnaire was posted to Chief Executives of each metropolitan local government (Councils) in South Australia (SA) and Victoria (Vic) in April 2008. Responses were received from 18 of the 20 SA Councils (90%) and from 19 of the 28 Vic Councils (70%). In response to the question:
“In an ideal world, what process or measure do you think local government needs to implement to make a
positive impact on climate change?” a variety of responses were received. These have been summarised in Figures 1 and 2.

“In your opinion, what are the barriers to local government implementing the ideal process or
measure?” the responses from Councils were also varied. These are summarized in Figures 3 and 4. These barriers are mainly financial, political, institutional, infrastructural or social. These findings support that of other research studies concluding that the barriers to implementing measures to address climate change at the local level are generally not technological.

MotivationMitigation towards sustainable transport is particularly challenging task that Australia is currently facing and will face in the next several decades. However, if this problem is not addressed adequately now, the potential rise of transport GHG emission will jeopardise GHG emission reductions that could be achieved in other sectors of the economy with costly efforts. In the expected conditions of growing demand for transport services the most appropriate action to contain transport GHG emissions within the required limits is to effectively miti-gate to more GHG efficient Australian vehicle fleet.

Institute for
Transport Systemsand Technologies -Sustainable SystemsInstitute for “Sustainable Transport”
Sustainable Transport has recently become an important concern for transport and land-use planners. It is a concept developed in reaction to the consequences of visibly gone wrong transport and land-use policy and development over the second half of the past century – Urban transport systems that relied on personal vehicle, have proved unsustainable, consuming excessive energy, affecting the health and environment, and delivering a declining level of service despite increasing investments.
Motorcycle and Asian developing countries
Recently, a pre-study has been established. 9 travel surveydatabases undertaken in 8 mid-sized cities of Thailand,between 2003 and 2008, were taken into the analysis.Several statistic evidences from this study do help us toroughly picture how the relationship between motorcycleand Asian people looks like. In this poster, 4 evidences arepresented:
• The first chart (the pine chart) shows the average proportion of household car and motorcycle ownershipamong those mid-sized cities. Almost 90% of urbanhouseholds own at least 1 motorcycle.
• The second chart (the colour column chart) shows the proportion of trips made by various transport modes.Over 50% of trips are typically made by motorcycle whileless than 10% are made by public transit.
• The other 2 charts (on the green hatch) present somefindings from an attitude study on motorcycle in a mid-sized city in Thailand. Majority of people have a neutralto highly positive to using and owning motorcycle.
These imply a strong motorcycle dependency, and also the difficulty in changing traveller behaviour and introducinga more sustainable transport mode.
No it is not!
Neutral
Yes it
is!
A study to define possible way to introduce more sustainable transport systems into mid-sized cities of Asian developing countries. Conceptually, for the first step the reasons behind traveller behaviour and decision making need to be investigated using several approaches e.g. statistics, choice modelling and activity-based analysis. The further step is to define the strengths, weaknesses, opportunities and threats (SWOT) involved in each reason contributing MDE, and seeking for a point that we could potentially force people with a new policy and/or development strategy to introduce more sustainable transport system while reducing use of previous unsustainable systems. Stated Preference approach would play important role in this stage. A brief diagram of the study methodology is shown on the left hand side. This study chooses Thailand as the principle study area. A further study could be an extension of the study area to other Asian developing countries.

Why mid-sized cities? It is the fact that over 60% of urban population in Asian developing countries lives in mid-sized cities (population of between 50k and 500k).Most previous studies in motorcycle dominant environments were however established in such large cities with multimillions population. We know there are manydiscrepancies between mid-sized and large cities that could contribute to different people behaviour and lifestyle. That means the policies as well as developmenttechniques suggested for those large cities perhaps do not fit to the mid-sized cities.
Motorcycle seems to be a signature of Asian developing countries!We all know that there is a massive use of motorcycles in most urbanareas of those countries, called Motorcycle Dominant Environment (MDE).Recent studies have affirmed that the great contributions of MDE could below-income, rapid urban expansion and deficiency of public transitservices. Although, the unique characteristic of motorcycle could fill upthose gaps and provide a lot of benefits to the owners under the condition,it also causes many serious transport issues. In which to develop‘Sustainable Transport’ in those countries, the impacts of motorcycle must be seriously taken into account.

Case Study
What is Citizen Science? Scientists work to understand the complexities of the natural world. This endeavour often requires a great deal of data collection, but time and resource availability limit the data collection that scientists can do. One solution to this problem is to have more people collecting data, and this is where Citizen Scientists can assist. Members of the community can help further our understanding of the natural world by collecting data and submitting their findings.
Citizen Science is more than just data collection. In order for a research project to work properly, Citizen Scientists need adequate information about what they are studying and how to study it. So scientists must produce information for the community, to inform them about the project and the subject of the study. Additionally, scientists must provide feedback to participants once the results of the study are finalised, in order to
maintain the engagement of the Citizen Scientists.
There are many benefits of Citizen Science. Community members get a chance to inform scientists, and, in the process, learn more about their environment. Further, information gained through Citizen Science projects can change public perceptions of the natural world, promote interaction with nature, and engage the community in the management of natural resources. Scientists benefit from data collection over
a large area, or over a long period of
time. Data can also be
collected from areas that are
normally difficult to access, such as private
property, or at times when fieldwork is
sometimes challenging, such as at night-time.
Operation Possum is a Citizen Science project that has collected information about possums and how people interact with them in South Australia. With the support of local and regional radio through ABC 891 Adelaide, researchers from the Barbara Hardy Centre have been able to collect data from around the state. The public response to Operation Possum was tremendous. Over 2,300 surveys were completed via an online survey instrument over a three month period in 2008. Figures 1 and 2 show survey returns from towns and suburbs in South Australia.

Macroscopic models represent travel movements with aggregate vehicle flows over a given time period, e.g. peak, off-peak or daily. Interactions between individual vehicles are largely ig-nored as traveller demands are estimated from socio-demographic and land-use data. Still, some output from macro level models can be useful as an input to micro level models ei-ther as a model calibration indicator or simply as a pure input to the modelling process. For example, travel demand origin-destination matrices produced by the macro level models are basic input to the microsimulation.
The microscopic modelling is based on a representation of de-tailed transport networks capturing individual vehicle move-ments, driver interactions as well as the operation of signalised intersections and multimodal interchanges. These models are capable of estimating traffic interaction dynamics and providing a more detailed expression of network operations in comparison to their macroscopic counterparts. Microsimulation software can simulate vehicle and engine responses to driver perceptions and reactions, the individual vehicles in road traffic and vehicle flows on a length of road or through an intersection. As the name sug-gests, microsimulation refers to the simulation of detailed road networks (individual vehicles). Microscopic models use a sto-chastic process for traffic modelling. This means that traffic con-ditions are simulated and variability is statistically built into the system. Therefore, for the same input data, a range of traffic conditions can result therefore better mimicking what occurs in the real world. Such variations are largely due to a mix of driver characteristics where, for example, some modelled drivers are more aggressive than others.
Traditional strategic-level macroscopic trans-port models based on static network equilib-rium are not able to incorporate many impor-tant aspects of dynamic traffic behaviour. When the need arises to gain more detailed assessment of transport networks and individ-ual vehicle interaction, microsimulation mod-elling is a more appropriate approach. Both macro and micro approaches have their own advantages and will continue to play impor-tant role in transportation modelling.Linking the strategic macro and micro level models enables a harmonious information ex-change. This ultimately improves the cost-effectiveness in the development, application and maintenance of both model types. Bridg-ing the two scales of modelling will greatly en-hance operational speed and the ability of both model types to forecast traffic conditions.

From Macro to Meso to Micro (from Barcelo, 2005)
Developing a traffic microsimulation model of Adelaide City area The traffic model was constructed using Paramics microsimulation software as it is considered to be one of the best of its type and has found widespread use with road agencies and consultants within Australia. The Application Programming Interface also allowed increased functionality for testing Intelligent Transport Systems (ITS) scenarios.
3-D simulation Microsimulation software commonly of-fers a three-dimensional interpretation of the results. This type of output is repre-sented as dynamic traffic movement in real time with the movie capturing capa-bility.

Travel Time Reliability for Selected Adelaide’s Corridors
What is Travel Time Reliability ? The data is the eight consecutive years travel time data for ten Adelaide’s corri-dors as shown in Fig-ure 3.
The travel time data were collected by us-ing GPS by The South Australian Department for Transport, Energy and Infrastructure (DTEI).
Travel time reliability is an important performance measure for not only the road users, the freight industry but also for the traffic planners.
The reliable travel time will : 1. Improve the traffic performance 2. Help the road user to select their preference departure time
by taking into account the unexpected delay during their trip 3. Help the road user to choose the reliable route 4. Help the freight industry to arrange their delivery time 5. Help the traffic planner to select proper policy in order to
improve traffic performance
Travel time reliability can be defined as the probability to finish a trip within specified time by taking into account the unex-pected delay.
According to Federal Highway Administration (2006) travel time reliability is the consistency or dependability in travel times, as measured from day-to-day and/or across different times of the day.
By acknowledging the travel time reliability and variability, the

Discussion and Findings
�� This study examines the ten selected corridors of the Ade-laide Road networks by using the eight consecutive years of travel time data.
�� From the data analysis, it is found that there were many differences in buffer time index results among the corridors and for some the differences are much larger than others.
�� In addition, the buffer time index might be not be enough to represent the travel time reliability due to the significant variability of the travel time

BackgroundCracking clay soils (Fig. 1) are present in South Australia’s arid rangelands. Shelters are limited in arid areas and cracking clays may provide refuge for arid-zone plants and animals (Fig. 2 and Fig. 3). These soils may be particu-larly important habitat for small mammals, including planigales (Planigalespp.) and threatened rodents (Read 1981; Brandle and Moseby 1999). Anec-dotally, it appears that where cracking clays are present, small mammals such as dunnarts (Sminthopsis spp.) exist in high numbers. Pastoralism (grazing) is the dominant commercial land use in the rangelands (Smyth & James 2004); it has been identified as a key threat to rangeland biodiversity (Pringle & Landsberg 2004).

MethodsCrack attributes such as depth, width, and length will be measured at grazed and less-grazed sites in order to define their physical structure. Data loggers will be used to determine the temperature buffering and humidity regulating role of cracks. They will be placed in selected cracks and programmed to record data over 24-hr periods, in different seasons. I will com-pare differences in shelter properties between cracks from grazed and less-grazed sites.
Expected outcomes Some of the anticipated outcomes of this research include increased understanding of:
�� the value of cracks as shelter for arid-zone biota; �� the impacts of pastoralism on what may be critical habitat; and, �� the role of cracking clays in biodiversity maintenance in the arid zone.

I commenced a Ph.D. in Environmental Management after completing a Bachelor of Applied Science (Biodiversity, Environmental and Park Management) (Honours). I became interested in cracking clay soils while working as an Environmental Consultant in the South Australian rangelands.
Aims & research questions I aim to determine the shelter properties of cracking clays. My research questions are 1a) what is the role of cracks in temperature buffering and humidity regulation; 1b) how does this role affect crack shelter proper-ties; 1c) what is the effect of grazing on the shelter properties of cracking clays?

Abstract The sources of uncertainty/vagueness in travel demand model are not only from the lack of information related to the parameters that the model tries to estimate but also due to the presence of qualitative/linguistic variables which are often occurred in human thinking. Fuzzy Set Theory (FST) is suggested can tackle the computation of such variables. Combined with other approach, in this case Artificial Neural Network (ANN), a hybrid approach is promoted to forecast intra city working trip distribution with trip length addressed as a fuzzy variable. FST is used to calculate the qualitative/fuzzy variables, while ANN is used to estimate the distribution of journey to work.

Question 33 : What is Artificial Neural Network? In short, it is a method that tries to mimic “human brain” in predicting future events by processing information transmitted from the adjacent input neurons and re-transmitted to the output neuron(s) Question 4 : Can FST and ANN be used together? Yes, and they are expected can have higher performance
Hints : The distance is a fuzzy variable because the following facts : 1. Most travellers would not know the exact distance travelled from origins and destinations 2. Each traveller starts to travel from different points within an origin zone to different points in the destination zone
