Past Seminars


Sean Doherty

Date: 2 December 2008

Speaker: Associate Professor Sean Doherty, Department of Geography and Environmental Studies, Wilfrid Laurier University, Canada

Topic: Tracking humans: emerging technologies and health applications Adobe PDF Document

Bio: Dr. Sean Doherty is an Associate Professor in the Department of Geography and Environmental Studies at Wilfrid Laurier University. His interests focus on human activity/mobility patterns and decision making, including tracking methods, modeling, and the impacts on health, safety, and the environment.  He is currently leading several research projects involving application of a personal Global Positioning System (GPS) tracking system to the study of diabetic patients, home-care patients, tourists, and immigrants.  Partners in these projects include Research in Motion (RIM), Telus, and Innovations at the University of Toronto.  Dr. Dohertys also enjoys an active family life and is an avid hockey player.

Abstract: The growth in personal location and biophysical sensing technologies, and the ability to obtain/transmit this data in real-time, is presenting new opportunities to explore personal geographies (in the form daily life/events, mobility, and exposure) and physiological outcomes (such as energy expenditure, heart rate, blood glucose) under real-world conditions in the built environment.  Transforming the plethora of data into useful understandings, interventions, feedback, and clinical/methodological tools is a key future challenge.  This seminar will present a review of emerging passive tracking technologies (including especially GPS and accelerometry), supplemental interactive and in-situ survey methods, present examples drawn from recent field studies (including diabetic patient monitoring), and challenge attendees to consider future applications in public health and safety.

Brett Day

Date: 11 November 2008

Speaker: Dr Brett Day, University of East Anglia, ITLS Visiting Academic

Topic: Modelling demand for new cars in the UK using aggregate and disaggregate data Adobe PDF Document

Abstract: This seminar reports on work undertaken to develop an empirical model of purchasing behaviour in the new car market. The research is motivated by policy-makers desire to forecast the impacts of fiscal policies designed to incentivise the purchase of fuel efficient cars over gas-guzzling alternatives. The seminar will focus primarily on the on-going programme of empirical modelling. At the core of that programme is a standard discrete choice model of household purchasing behaviour applied to an aggregate dataset recording market shares for each model of vehicle available in the UK car market. The seminar will discuss the possibilities for (and limitations of) recovering parameters of the choice function from that aggregate data. Furthermore, the seminar will discuss the possibilities for augmenting the analysis with information from disaggregate data on individual purchasing behaviour in order to better identify the choice function parameters.

Bio: Dr Brett Day is a visiting academic at ITLS from September to December 2008. Brett is a senior lecturer in environmental economics at the University of East Anglia in the UK. His research focuses primarily on identifying economic preferences for non-market goods using market, survey or experimental data. Brett has a strong background in micro-econometrics which forms a recurrent theme in his research. Currently Brett is involved in a variety of projects. Of particular interest are projects looking to integrate the spatial dimension into the valuation of geographically distributed environmental goods using both revealed and stated preference techniques. Also, projects examining the impact of fiscal policies on market demand for greenhouse gas generating products.

David Walters

Date: 30 September 2008

Speaker: Professor David Walters, Professor of Logistics and Supply Chain Management, ITLS-Sydney

Topic: The role of logistics management in the new business model

Abstract: Manufacturers struggle to make their operations respond rapidly and effectively in an environment with myriad uncertainties. Meanwhile, their customers continue to demand faster service, a greater variety of products and the hottest new items. In this intensely competitive environment, balancing demand and supply and profit must be done daily - sometimes hourly. Success depends on how fast and how effectively brand owners and manufacturers can respond to change Ventana Research (30 July 2008). This statement reflects the growing consensus among research organizations on the challenges that will confront manufacturing and service industries in the near future due to the rapidly changing business environment. This seminar identifies some of the emerging business models and their likely implications for logistics management.

Juan Carlos Martn

Date: 19 August 2008

Speakers: Dr Juan Carlos Martn and Dr Concepcin Romn

Topic: Analyzing demand for new high speed train services: The case of Madrid-Barcelona Adobe PDF Document

Abstract: This paper analyzes the potential competition of the high speed train (HST) with the main competing modes in the line Madrid-Barcelona, where a new HST infrastructure has recently been built. The analysis is based on the estimation of a Nested Logit model that uses a mixed revealed/stated preference dataset providing information of travellers behaviour in the available modes. We obtained the value of the different components of the travel time as well as the willingness to pay for other service attributes and analyze demand response to various policy scenarios that consider the potential competition between HST and other modes. Results highlight the low level of competition that the HST could exert over the air transport services in this corridor.

Mark Streeting

Date: 12 August 2008

Speaker: Mark Streeting, Principal, Booz & Company

Topic: Fare policy reform in the Smart Card era Adobe PDF Document

Abstract: Public transport operators around the world have been progressively migrating from ticketing systems employing traditional fare media (e.g. paper and magnetic stripe tickets) to state-of-the-art contactless smartcard systems since the late-1990s. The introduction of this new technology has provided a unique opportunity to review fares and ticketing policy and leverage the full functionality of these new ticketing systems - including time-of-day and service-based pricing. Drawing on the results of a large-scale international survey, Mark will consider the extent to which the opportunities afforded by these new ticketing systems are being exploited in practice.

Hal Morris

Date: 10 June 2008

Speaker: Hal Morris, Chief Executive, Australian Logistics Council

Topic: Australias transport network  How did we get here and where are we going?

Abstract: Australias transport and logistics sector directly contributes $150 billion to our economy every year and underpins every other industry. Historically, however, our sector has seemed to be invisible to policy makers, with it often said the founding fathers forgot transport. This has resulted in ad hoc decision making with consequences including: conflicting regulations between states becoming a de facto barrier to trade; the federal government with no constitutional role or mandate to take the lead in reform; a reluctance for jurisdictions to focus on interstate connections, instead building intrastate networks with their capital city as the hub; and a lack of understanding of the importance of transport and logistics to our state and national economies. So if the system is broken how do we fix it? What is the map for reform?

Bio: Hal Morris started work as the Chief Executive of the Australian Logistics Council in January 2005. The ALC is the national umbrella body for Freight Transport and Logistics across Australias domestic and international supply chains. The ALC is also a partnership between all Australian Governments and the senior leaders of logistics including customers, users, suppliers, and industry modal peak bodies, the State-based Freight Councils, senior government officials, regulators, industry specialists and Unions. Among other responsibilities, the ALC is responsible for leading industry in the development and implementation of the National Transport and Logistics Industry Strategy 2008-2015. Before the ALC Hal worked in Queensland in various roles including Strategy and Government Affairs for QR, in the National Transport Secretariat, as an Executive Director in the Queensland Department of Premier and Cabinet and as a Regional Director in the Queensland Transport Department. Hals early career was in the Australian Regular Army where, after graduating from Duntroon, he flew helicopters in Army Aviation. He holds an honours degree from the University of New South Wales and post graduate qualifications in Business Studies from New England University. He is a Director on a number of commercial and advisory boards.

Date: 1 April 2008

Speaker: Professor Michiel Bliemer, ITLS/Delft Partnership Visiting Professor

Topic: Route choice modelling: Generation of route choice sets and their impact on route choice probabilities Adobe PDF Document

Abstract: Network traffic assignment models are widely used by policy makers, which can assist in assessing infrastructure investment decisions, road pricing policies, etc. A main component of these models are route choice models that describe the route choice behaviour of the individual travellers. Route choice models determine the probability that a traveller will choose a certain route from a route set. In the presentation two problems will be investigated: (1) how to generate a route choice set, and (2) how to compute route choice probabilities. Considering the first problem, in real life, the number of routes from origin to destination is very large, although only few routes will actually be considered by travellers. We will show a simple method for generating a set of routes that can distinguish between relevant and irrelevant routes. The second problem of determining the route choice probabilities is a more challenging one. Typically, a multinomial logit (MNL) model is applied to determine these probabilities and this model is robust against adding irrelevant routes. However, routes are likely to overlap, in which case the MNL model produces biased results. Adapted logit models have been proposed, such as the C-logit model, the path-size logit model, the paired combinatorial logit model, and the cross-nested logit model. Although these models are able to deal with route overlap, they turn out to be very sensitive to including irrelevant routes in the route set. Some surprising and unexpected results will be shown to illustrate this problem (e.g., longer routes becoming most preferred). This basically questions all widely used traffic assignment models as none seem to be able to deal with this problem adequately.

Bio: After finishing his Masters degree in Econometrics and Operations Research, Michiel Bliemer received his PhD in transportation planning and traffic engineering on the topic of dynamic traffic assignment with heterogeneous travellers. Currently, he works as Associate Professor at Delft University of Technology in The Netherlands and since three years as Adjunct Professor at the Institute of Transport and Logistics studies in Sydney. Main research topics include (large scale) analytical dynamic network models for forecasting future network conditions and effects of dynamic traffic management measures, particularly the impact of road pricing. Another important research topic is the design of efficient stated choice experiments for estimating discrete choice models. Other topics of interest are travel choice behaviour under uncertainty, dynamic queuing models, and optimal control problems with conflicting interests using game theory.

Ada Suk-Fung Ng

Date: 11 March 2008

Speaker: Dr Ada Suk-Fung Ng, Lecturer in Logistics and Supply Chain Management, ITLS-Sydney

Topic: Heterogeneous full-truck-load routing policies

Abstract: The transportation and trucking industry remains one of the most important fields in the area of freight logistics. Recent advances in computing speed and power have led to a wide variety of applications being developed in the field of the trucking industry. Due to the increasingly demanding nature of servicing the transportation of goods between different locations, it has become more important for trucking companies to adopt more up-to-date methods of handling operational activities. In this paper, we look into the case study of a nationwide transportation and trucking company in Peninsular Malaysia. The trucking company maintains a heterogeneous fleet of trucks, providing long-haul trucking services to various customers across the country. Trucks originate from a main depot (situated in the Northern region), and are dispatched to various parts of the country to service customer demands. Customer orders are received for the pickup and delivery of full truckload goods on a daily basis. Each customer order defines an origin-destination pair. Goods are picked up at an origin location and delivered to the destination location. In most cases, customers generally require next-day delivery service. Based on this study, our objective is to effectively assign trucks to customer orders (or jobs) in various locations, in order to minimize costs due to deadhead travel between the various pickup and delivery locations, and delay in deliveries. Using a rolling horizon approach, we propose a set of solution policies for addressing the needs to assign trucks to jobs on a day-to-day basis. The policies proposed are based on the offline version of a mixed-integer programming formulation originally developed for the homogeneous truckload pickup and delivery problem. Data obtained from the company are tested using our solution policies. Computational results show that all of the policies improve the companys truck utilization.

Date: 26 February 2008

Speaker: Associate Professor David Layton, Visiting Professor, ITLS-Sydney

Daniel J. Evans School of Public Affairs, University of Washington in Seattle

Topic: Continuous spatial choice - old, new, and emerging connections between fisheries economics and residential location choice

Abstract: Our motivating policy analysis goal is to estimate the economic impact of closing small areas to fishing out of a very large spatial area in order to protect an endangered species. To do this we need to create estimable models that can predict spatial location choice at an exceptionally fine spatial level. To date, spatial location choice modeling has focused on modeling space as a set of discrete zones and then applies discrete zonal choice models. We explore how an earlier, but apparently little used, literature on joint residential location choice and transport mode choice might be used to model continuous spatial choice where the decision maker chooses to locate, or fish, at one point in space.
