This online training program is offered for traffic and transport professionals and students with any level of experience. It will be of benefit to people interested in the essential concepts of traffic modelling and principles of traffic analysis.

This program has been prepared by Dr Rahmi Akçelik, a leading scientist and software developer with 50 years of practical, research and training experience in the area of road traffic operations, traffic engineering, management and control.

Upcoming Events

These listings include important information on pricing, currency, time zone and payment.

Left-Hand Traffic | Metric

We have prepared presentation content according to driving on the left-hand side of the road and using Metric units for countries such as Australia, New Zealand, South Africa, Malaysia, Singapore, India and UK.

Key Focus

This training will focus on traffic variables, concepts and principles that need to be understood for effective intersection and network modelling from a practical perspective using an analytical software tool such as SIDRA INTERSECTION. These traffic variables are of importance in preparing input, interpreting output, and calibrating the model for best representation of real-life traffic conditions.

The knowledge gained at this online training will be useful generally in the use of all traffic and transport modelling software tools.

Technical Requirements

We will conduct these training sessions using Webex Meetings via a high speed Fibre connection from our office located in Melbourne, Australia.

Program Contents

The SIDRA MODEL FUNDAMENTALS online training program consists of 3 Modules.

SIDRA Presenters

The following presenters will conduct this training program:

Mark Besley is a scientist and software specialist who has worked in the traffic management area since 1980s. He has been making a significant contribution to the development of the SIDRA INTERSECTION software in collaboration with Dr Rahmi Akçelik during the last 30+ years. He has trained several thousand professionals in over 300 workshops, courses and seminars.

Mark has been involved in many aspects of research on traffic operations including traffic network models, incident detection, fuel consumption estimation, traffic data collection and analysis.

Dr Ian Espada joined Akcelik and Associates in November 2019 as a Senior Traffic Modeller / Analyst. Ian has more than 18 years of work experience in the role of researcher, transport/traffic planner, transport survey specialist, transport demand modeler, and transport economist. He had an 11-year career at the Australian Road Research Board where he was the team leader of the Network Operations Team under the Future Transport Systems Working Group. Ian worked for 7 years as a transport planner / modeller for ALMEC Corporation, Japan. He was also a sessional lecturer on transport demand modelling at Swinburne University for 10 years.

Ian has a Ph.D. degree in transportation engineering and planning from the University of Tokyo and an M.Eng. degree in transportation planning and traffic engineering from the Asian Institute of Technology, Thailand. Ian was the Australian representative to the World Road Association technical committee on road network operations from 2016 to 2019.

David Nash is an accredited SIDRA INTERSECTION trainer. He graduated from the University of Melbourne as a Civil Engineer in 1978 and attained a Graduate Diploma in Technology Management in 2003. He has over 35 years of experience in traffic engineering, having worked with the Commonwealth Department of Transport, Country Roads Board, Road Traffic Authority and VicRoads. He worked on the design and operation of traffic signals and the early SCATS installations in Melbourne and Singapore. He has also had overseas work experience in Indonesia, Thailand and Ireland. David has lectured in Transport Engineering at Swinburne University of Technology and conducts many workshops and webinars. David is Principal of Traffinity, a traffic engineering consultancy based in Melbourne, Australia. He is the secretary of the Institute of Transportation Engineers - Australia and New Zealand Section.

General Details

Please read the following important information about our training programs.

Available Modules and Prices are listed on the UPCOMING EVENTS page.

Different registration information for Australian and Overseas customers is given in the Eventbrite page.

Attending all available Modules is recommended. However you may choose to attend individual Modules at different times.

Separate Registration for each Module

Separate registration is required for each Module. For instance, if you would like to attend both Module A and Module B, you are required to register for each of these two Modules separately.

Units and displays in presentations and SIDRA project files will be configured according to region. These are based on:

  • SIDRA Standard Left software setup using Left-Hand traffic rule and Metric units.
  • SIDRA Standard Right software setup using Right-Hand traffic rule and Metric units.
  • SIDRA US HCM software setup using Right-hand traffic rule and US Customary units.

You will need to view two windows at the same time, one window to view the Presenter's desktop and another window to view the Training Book for exercises.

For Australian Events

We run our programs from Melbourne, Australia which observes two different time zones throughout the year -

Current time zone: AEST

For Other Events

We will list Local Programs under the closest time-zone for the local area. Please refer to the UPCOMING EVENTS page for details.

At the end of your Module, we will ask you to complete and submit a Training Evaluation Survey so we can get feedback on your experience. The information and feedback you provide is valuable for us in designing and improving our programs.

After completion of training, we will send you a Certificate of Completion. We will also send you links for downloading your Answers to Exercises Books.

  • You will be sent training books (PDF format) before the training.
  • The training will be in English.
  • We recommend that you watch these tutorial videos before the training.

By registering for this training, you are agreeing to the following conditions:

Understanding fundamental concepts and principles for effective intersection and network modelling

"A good understanding of traffic operations is essential for effective use of traffic models for intersection and network design, performance assessment and transport planning purposes. Model calibration is an important element of this process. SIDRA Training is not just about intersection and network analysis, but aims to improve general understanding of operational analysis of all traffic facilities."

Dr Rahmi Akçelik


Here are some positive comments from delegates who have attended our SIDRA MODEL FUNDAMENTALS online training program. Read More..

It was a good experience for the improvement and understanding of the basic and advance concepts of SIDRA. It helps to understand how things works and how to interpret the results. The basic clarification is extremely necessary to find solutions for a particular problem/scenario.

Udit Bhatti
