Topic:Development of a framework for roadspace reallocation in relation to transit priority Adobe PDF Document
Speaker:Dr Majid Sarvi, ITS-Monash
Abstract:The re-allocation of available roadspace to provide priority for transit is increasing at a rapid rate worldwide. The case for re-allocation of roadspace to transit is clear where service and passenger volumes are substantial. However at lower volumes, the need is less clear since the benefits to transit are small but the impacts on other road traffic large. This work summarises the major elements of a research project aimed at defining a balanced framework for roadspace reallocation in relation to transit priority. The framework aims to clarify the trade-offs required in developing transit priority systems in a range of traffic circumstances and to provide a balanced allocation of road space based on the full range of impacts. In particular, the approach focuses on people travel and not vehicle travel. It utilizes advanced traffic micro-simulation approaches to better understand the on-road operational implications of alternative transit priority measures and develops a social cost benefit analysis framework to comprehensively value the benefits and costs of priority measures to transit and traffic travellers. The impacts on general road congestion and wider environmental, economic and social impacts are considered.

Topic:Modelling of emergency evacuation of transportation networks Adobe PDF Document
Speaker:Professor Essam Radwan, ITLS-Sydney Visiting Professor, Professor and Chair of Department of Civil and Environmental Engineering, Executive Director, Center for Advanced Transportation Systems Simulation, University of Central Florida
Abstract:Emergency situations can require a regional ability to move large numbers of people in a safe and timely manner. A regions evacuation strategy encompasses a variety of areas and needs, many of these interdependent and interrelated. The main objective of this research project is to examine the policies, procedures, and components that affect and are affected by emergency evacuation events. Tasks outlined for this study include: thoroughly review the literature for past studies, identify available transportation evacuation models that are in the public domain, formulate the framework for emergency evacuation, and test the proposed framework on a selected site in the central Florida region. Thorough evaluation of the literature revealed that most emergency evacuation models adopt a loading curve for the transportation network that follows an S curve. Published studies on human behavior lacked the data to support this assumption about the S curve and it appears that there is a need to carryout further investigations on this subject. Further investigation showed that top level optimization algorithms are limited in scope and there is room for improvement to these models. A scoring system may be used to identify areas with highest priority for evacuation. A GIS system supplemented by contour line mapping can be used to identify traffic bottlenecks downstream of an evacuation route. By addressing these problem points first a smoother evacuation process may be developed that will reduce network clearance time. Two separate tools and techniques for evaluating and improving evacuation planning for regions and situations are being assessed. The proposed framework will be tested on the City of Daytona Beach, a major coastal metropolitan area that is subject to a variety of threats, including hurricanes.

Topic:What you measure is not necessarily what you get! The mediating role of socialization in strategic buyer/supplier relationships
Speaker:Professor Paul Cousins, Chair in Management (Operations Management), CIPS Professor of Strategic Supply Management, Head of Supply Chain, Innovation & Policy Research Group, The Queen's University of Belfast
Abstract:This paper conceptualises and empirically examines the impact of performance measures and socialization mechanisms on the achievement of shared performance outcomes within strategic buyer-supplier relationships. Prior research has pointed to the importance of using performance measures to manage supplier relationships. However, we argue that inter-organizational socialization mechanisms, which establish communication channels and facilitate information sharing, may play an important role in mediating the relationship between performance measures and shared performance outcomes. A structural equation model, using a sample of 142 manufacturing firms based in the United Kingdom, indicates that socialization mechanisms fully mediate the effects of operational-based performance measures on shared performance outcomes. Socialization was not, however, found to be a mediating variable for communication-based performance measures. Managerial implications and future research directions are discussed.
Bio:Paul is Professor of Operations Management, head of the Supply Chain, Innovation & Policy Research Group and Director of Research: Higher Degrees in the School of Management and Economics at The Queen's University of Belfast. His career to date has spanned a range of business sectors from industry (Westland Helicopters & Sikorsky Aircraft), consulting (A.T.Kearney & McKinsey) to academia (University of Bath and The University of Melbourne). It has led him to work in a variety of countries including the UK, Europe, USA, Australia and now Northern Ireland. He has generated over 1.5m in research grants and has conducted research and consultancy work for numerous firms across a range of industrial sectors at national and international level. Paul's main research interests focus on the area of supply management: Strategic Supply Management, Environmental Supply and Inter-Organisational Relationship Management. Paul's research generally combines both a qualitative (case studies and interviews) and quantitative (structural equation modelling, moderated hierarchical regressions and descriptive statistics) approaches to research design and analysis. This is reflected in his published journal papers and books.

Topic:Airfreight market overview and challenges for intercontinental freighter operators
Topic:Mr Frederic Horst, Lecturer in International Freight Transport, ITLS-Sydney
Abstract:International airfreight remains concentrated around and between major gateways in North and Southeast Asia, North America and Western Europe. All other markets, including Australia, are small in the "grand scheme" of things. Nevertheless, small markets can generate interesting business opportunities for network based freighter operators. This seminar discusses the structure of the worldwide air cargo market, as well as examining some of the critical success factors of profitable intercontinental freighter operations.

Topic:How do respondents handle stated choice experiments? - Information processing strategies under varying information load
Speaker:Professor David Hensher, Director, ITLS-Sydney
Abstract:The popularity of stated choice (SC) experiments has spurned a large number of design strategies in which researchers use increasingly more complex choice settings within which to study choice behaviour. When the amount of information provided increases, we often wonder how an individual handles such information in making a choice. Defining the amount of information (or complexity) as the product of the number of attributes and number of alternatives associated with each choice set (or treatment), we investigate how this information is processed as we vary the amount of information. Four ordered heterogeneous logit and mixed logit models are developed, each for a fixedattribute design, in which the dependent variable is the difference between the maximum (fixed) number of attributes in the design and the actual number that were maintained by the respondent in their information processing strategy (IPS). Potential influences are the dimensionality of the SC experiment (i.e. number of levels of each attribute, numerical range of these levels, the number of alternatives, the number of choice sets), the deviation of the design attribute levels from the reference (or overtly experienced) alternative, the use of adding up attributes where this is feasible (e.g. travel time components) and other contextual effects such as the socioeconomics characteristics of the respondent. We have found that individuals adopt a range of coping strategies that are consistent with how we normally process information in real markets. Importantly we should not argue that more information is necessarily undesirable; indeed such information may be necessary to give meaning (i.e. relevancy) to a choice context even if an individual invokes an IPS that involves excluding specific attributes and even aggregating them. Indeed aggregating does not imply that we should provide the aggregated attribute in the design but rather that this information is often useful (it is not ignored), and a respondent prefers to be aware of it and add it up in the processing of the SC experiment. This should not be seen as necessarily cognitive burden indeed limited information may in itself be especially burdensome where it is an incomplete representation of the attribute space that matters to an individual. The evidence suggests that aligning choice complexity with the amount of information to process is misleading. Relevancy is what matters.

Topic:AUSTRANS The smart people mover for today (PPT)
Speaker:Piers Brogan, Commercialisation Manager, Bishop Austrans
Bio:Piers Brogan is a civil engineer and city and regional planner who has a particular focus in transport planning and infrastructure delivery. Piers first came to Australia in the early 1970s to find Sydneys second airport. Subsequently he was involved as a consultant in many major studies into Sydneys airports including being Director-in-charge of the Long Point and Badgerys Creek EISs in the 90s. Piers has worked on multi-modal transport projects in Europe, The Caribbean, Latin America, The Gulf, Africa, Asia Pacific and Australasia. He founded Australia;s largest boutique transport planning and economics consultancy, Travers Morgan. More recently he was instrumental in rebuilding PPK/Parsons Brinckerhoff to be a first division player in the transport business. Piers has been with Bishop Austrans for a year or so tasked with commercialising the revolutionary Austrans concept.
Abstract:A short video will be played initially which describes the key components of the Austrans system and how it can provide a new 21st century public transport solution to compliment the existing heritage modes. The presentation then illustrates the broad financial attributes of Austrans; the very significant passenger benefits; and itls outstanding environmental credentials. The presentation then focuses on a series of real life case studies where Austrans is compared with a city rail service; a light modern rail application; and a busway or transitway. The comparisons cover financial, passenger benefits and environmental performance. The presentation concludes with a brief discussion of the way forward for Austrans.

Topic:A Critical Review of Intercity Freight Forecasting Models in the US
Speaker:Professor Alan Horowitz, ITLS-Sydney Visiting Professor, Professor of Civil Engineering, University of Wisconsin
Abstract:Governmental planning agencies in the United States have begun to recognize the need for better intercity freight forecasting models for developing and managing transportation infrastructure. A recent review of all intercity freight forecasting models by public agencies in the US (performed for the National Cooperative Highway Research Program) revealed a wide variety of approaches and data sources. A dominant paradigm has not emerged. Many of the models are conveniently derived from the methods of passenger travel forecasting and do not necessarily reflect current thinking about carrier or shipper behaviors. Three prevalent styles of intercity freight forecasting in the US are critiqued and future avenues for model improvement are suggested.

Topic:Induced technical change and climate control policy Adobe PDF Document
Speaker:Dr Truong Truong, ITLS-Sydney Visiting Fellow, Senior Lecturer, School of Economics, University of NSW
Abstract:Technological change plays an important role in climate control policies. To constrain climate change, emissions from the usage of fossil fuels must be reduced. This can come about partly from an improvement in energy efficiency but beyond a certain limit, significant reductions in emissions can only be achieved if there are significant shifts away from carbon-based to carbon-free fuels. Such a shift will happen only if there are technological advances in the use of efficient technologies and cleaner fuels. How and when such technological advances can come about depends on the workings of two competing forces. On the one hand, the long term benefit of cleaner activities will encourage more investment towards the development of clean technologies, but on the other hand, the short term costs of stringent climate control policies may discourage such investment. Understanding the relative strengths of these two competing forces is important for the design of optimal climate control policies. In this paper, a model which is used to analyse these two competing effects is described, and the results from an experiment using this model will be discussed.

Topic:Dynamic traffic modelling and road pricing on motorway networks Adobe PDF Document
Speaker:Professor Michiel Bliemer, ITLS-Sydney Visiting Professor, Delft University of Technology, The Netherlands
Abstract:Using dynamic traffic assignment models, we are able to forecast travellers' behaviour on networks for long-term planning purposes. These models consist of two main parts, namely a traffic simulator describing the congestion effects and delays, and a route choice (and departure time choice) model. This model framework can also be used to predict effects of dynamic road pricing measures. Using game theory and bi-level optimisation, first-best and second-best road pricing schemes can be analysed and optimised. In the presentation, the components of the developed network model INDY will be described, some specific areas of application will be mentioned, and the road pricing study currently conducted in The Netherlands will be discussed.
