LinSig3.2 : SCATS Modelling Workshop Australia and New Zealand (A two day course)


Accurate LinSig modelling is fundamental to traffic signal design, transport assessments for development and detailed studies where traffic signal junctions are a major determinant of transport outcomes.


This intensive course covers the use of LinSig 3.2 to model traffic signal junctions and networks. It starts from first principles including Signal Groups, Phases, Clearance Times and Pedestrian Protection and then moves quickly on to examine network building, Route based and Lane Based modelling, SCATS flow import, matrix estimation, the use of cyclic flow profiles and modelling buses. The course is computer based with practical workshop exercises based on real junctions in Australia and New Zealand used throughout.

Who should attend

This course is suitable for anyone who uses or will use LinSig for modelling traffic signal junctions and networks and who requires a comprehensive base of knowledge to ensure their modelling is robust and accurate.


Delegates are expected to have a basic understanding of how traffic signals work and know what is meant by terms such as Signal Group, Phase and Clearance Time, a brief recap on Saturation Flow, Degree of Saturation and Practical Reserve Capacity is included in the programme.


No prior knowledge or experience of LinSig is required.


All JCT courses are Approved or are pending Approval by the Institute of Highway Engineers and attendance is therefore recognised by the IHE and many other bodies as evidence of Continual Professional Development (CPD).


Courses are managed under a ISO9001 Quality Management System.

Course content

Since 1985, LinSig has been the industry standard modelling software for traffic signal design and assessment in the UK. In 2009 LinSig 3.2 added the ability to model networks and introduced a SCATS controller model which has been refined over the years to accurately represent Signal Groups, Phases, Clearance Times, Pedestrian Protection and SCATS flow import. This two day workshop is key training for anyone new to LinSig who needs to produce efficient and accurate modelling as part of traffic signal design or transport assessments.

The course involves extensive computer usage and covers the following topics:

Day 1

Overview of main LinSig3 & SCATS Based features including lane based modelling, short lane control and blocking, assignment of flows to lanes and routes, comprehensive modelling of traffic signal controllers, pedestrian links, flows, delays and crossing times.
Building a LinSig3 model on a suggested step by step basis including explanations of LinSig3 features in the context of building an actual model.  This includes the use of the many different data and results display options in LinSig.
Running LinSig3 models and interpreting the results.  This includes input of signal timings using timing dials or optimisation.  The detailed lane based results are explained and an overview is given of the report builder and print out options.
Modelling give-way left turns and opposed right turns, including a full appreciation of the components of right turn capacity dependent on the selected phase sequence.
Use of flow group formulae and component flow groups for the efficient modelling of multiple traffic scenarios in transport assessments.

Day 2

Modelling networks including the creation of networks from individual models, importing SCATS data and matrix estimation.
Understanding Cyclic Flow profiles in the context of a complicated double junction and applying cruise times, platoon dispersion and platoon compression.
Modelling buses with custom Bus speeds and dwell times.
