His first contact with the Transport Systems Centre (TSC) was in 1996 when he enrolled in a Postgraduate Diploma Course in Transport Systems Engineering. After completing this course in 1997, for which he has received an award for excellence, he started working as a Traffic Operations Engineer at the Metropolitan Region of Transport SA in Adelaide.

Working there for two and a half years he was involved in:

• Developing strategies for Transport Network improvements
• Traffic System Management issues
• Identification of signalised intersection improvements
• Application of traffic monitoring equipment
• Application of vehicle and pedestrian detection equipment
• Writing technical documents and guidelines
• Budget management
• The analysis of Traffic data

He commenced working for the TSC in November 2000 as a Research Assistant. His expertise is in the field of traffic modelling especially in the use of PARAMICS, AIMSUN, SIDRA, VISSIM, SCATES and CUBE(formerly Trips) software. He is also experienced in the use of, and analysis and interpretation of data obtained from traffic counting equipment such as traffic classifiers (VDAS and MetroCounts), camera systems (CAMDAS) and radar guns. He is familiar with the operation of ACTS system, which is used to control the traffic signals in Adelaide Metropolitan area.

Some of the projects that he was working on recently are:

• Traffic microsimulation of Intelligent Transport System (ITS) implementations in Central Business District (CBD) road networks
• Development of Origin-Destination matrix for Adelaide CBD area using CUBE ME
• Development of vehicle profiles for Australian road networks to be used in Microsimulation and emission modelling
• Microsimulation Modelling of the Southern Expressway
• Modelling of corridor management strategy for the City of Adelaide using microsimulation
• Microsimulation modelling of City of Unley road network
• Microsimulation Modelling of Victoria Square in the Adelaide CBD

He is envolved in supervision of international exchange students and Australian undergraduate and postgraduate students working on microsimulation modelling. Students are learning the basics of microsimulation modelling including:

• Data collection and preparation for the use in modelling process
• Network coding (links, nodes, zones)
• Development of the existing scenarios for a road network
• Calibration and the evaluation of the model
• Development of the alternative scenarios
• Generation of the output parameters.
• Modelling of adaptive control systems (SCATS)
• The use of Advance Programming Interface to extend the capabilities of microsimulation software
• Emission and fuel consumption modelling
• Public transport priority modelling

• Transport Modelling, Traffic Surveys and Intelligent Transport System Technologies.
• Selected Projects:
  • The Review of Ella Bay Integrated Resort Project
    The Queensland Section, Environment Assessment Branch, Approvals & Wildlife Division, Department of Environment, Water Heritage and the Arts has requested a peer review of the Ella Bay Integrated Resort Proposal, in response to ongoing concerns about a preferred road access solution. The review project focused on the following issues: traffic generation issues, the use of multi-criteria analysis, traffic impact statement and comments on the supplied reports and drawings.
  • Traffic microsimulation of ITS implementations in CBD road networks (ARC linkage grant)
    This research project will investigate the advantages of using Intelligent Transport Systems (ITS) technologies in an Australian Central Business District (CBD) environment. It is often assumed that road networks and especially high activity areas such as CBDs can benefit significantly from ITS implementations. Traditionally ITS impacts have been difficult to quantify due to difficulties in isolating network effects and limitations with traditional traffic models. The project will overcome this difficulty by using a current state of the art traffic microsimulation model in order to test various ITS scenarios in a duplicate of a real world CBD.
  • Local Area Traffic Management Study:Leabrook-Hazelwood Park Precinct
    The study was conducted in order to determine the amount of traffic on primary and secondary collector roads and the proportions of through and local traffic. In addition, possible changes to current management of traffic were investigated.
  • The Analysis of Adelaide City Council Input and Output Vehicle Flows
    TSC has developed a computer cluster that it has been using to store and analyse traffic signal data. This data was extensively used in order to determine the number of vehicles that are flowing into and out of the ACC area.
  • Microsimulation Modelling of the Southern Expressway
    The extension of model of the reversible Southern Expressway in Adelaide was performed to include the second stage of the Expressway and Lonsdale Highway as a major alternative route. This will allow further modelling of the impact that an Advanced Traveller Information System (ATIS) and an Incident Management System (IMS) could have on vehicle travel on the Expressway and alternative Main South Road and Lonsdale Road routes.
  • Glenelg Tramway Extension studies
    The TSC was commissioned by DTEI to investigate traffic performance issues associated with the Adelaide tramway extension.
  • Modelling of corridor management strategy for the City of Adelaide using microsimulation Adelaide City Council, South Australia
    The project involved the modelling of Pulteney St and Frome St in the Adelaide Central Business District for the morning peak period. A microsimulation model was constructed of the two parallel routes and calibration and verification was performed using extensive data from the City Council. Signal timings and linking were fully implemented along with all public transport routes. Proposed traffic management strategies were explored with the council and the benefit of new dedicated bus lanes was demonstrated.
  • Microsimulation modelling of City of Unley road network
    Paramics model was developed to assess the possible impacts of the traffic signals installation and the implementation of a number of other changes to the road network in City of Unley in Adelaide. Some of the alternative scenarios involved road closures, banning turning movements, median opening and closure. The model was used to analyse different schemes on a network basis, leading to a better understanding of the impacts of proposed, site related changes, on the surrounding roads.
  • Microsimulation Modelling of Victoria Square in the Adelaide CBD Adelaide City Council, South Australia
    The project involved the modelling of alternative layouts for Victoria Square in the centre of the Adelaide Central Business District. A microsimulation model was constructed of the square for various layouts including: the current diamond layout; a large unsignalised roundabout; a partially signalised roundabout; reductions in road widths and a fully signalised oval layout. The modelling showed that road closure of the centre of the square was not feasible and that all of the proposed layouts resulted in poorer levels of service than the current diamond layout. Modelling was performed for the morning peak, business peak and evening peak periods.
  • Review of Central Sydney Light Rail Modelling
    The TSC has conducted an external review of Central Sysdney Light Rail Route Evaluation for the Department of Infrastructure, Planning and Natural Resources in Sysdney, NSW.
  • North Terrace Upgrade Studies
    The project involved modelling and the evaluation of the alternative scenarios for one of the major arterial routes in the City of Adelaide area.
  • Testing and research of microsimulation models
    Paramics model was constructed for the purpose of comparison with the aaSIDRA analytical model (Akcelik and Associates 2000). The following aspects were tested:
    • Comparison of queue discharge flow characteristics of left, through and right turn movements
    • Effects of grade and heavy vehicles on queue discharge flow characteristics
    • Estimation of lane flows for an approach road with shared lanes, including the possibility of a de facto exclusive lane.
    A number of other models were developed in order to test different aspects of microsimulation models including: - Vehicle generation pattern - Saturation flow rates - Bottleneck capacity etc.
  • Traffic Modelling of arterial roads in Adelaide
    The project involved modelling of a number of major routes in Adelaide using SCATES software in order to determine the best off-set data for signalised intersections which are connected to ACTS system.
  • Signalised Intersection modelling
    This was an ongoing project that required regular modelling of the signalised intersections using SIDRA software. The software was used to determine the parameters to be used in the operation of signalised intersections across Adelaide Metropolitan area including: cycle times, phasing data, signal linking data.
