LinSig 3

A Design and Assessment Tool for Traffic Signal Junctions and Urban Networks


LinSig 3.2 is the current version of LinSig.

Since its original release in 1985 LinSig has been the UK industry standard software for the assessment and design of traffic signal junctions. Its unique attribute was and still is the combination of both traffic and controller modelling for comprehensive traffic signal design. The software has been instrumental in advancing UK phase (signal group) based methods of control giving maximum safety and efficiency for all road users.

One common application of LinSig is rapid testing of new traffic signal schemes which involve large numbers of alternative options. LinSig allows different options to be quickly modelled and rejected or taken forward possibly to more detailed resource intensive modelling such as microsimulation. Other common uses of the software include the interactive design of signalled roundabouts for which it is strongly established in the UK and overseas, transport assessments for land development and detailed modelling of networks of signal, priority and roundabout junctions.

LinSig's main features include:

  • Models networks of traffic signal, roundabout and give-way junctions for network sizes of up to 10-15 junctions depending on junction complexity.
  • Includes a detailed traffic signal controller model for UK TOPAS 2500 specification controllers.
  • Includes a SCATS™ based Controller model that allows signal controller data to be defined in a form consistent with SCATS traffic signal controllers.
  • Allows traffic signal timings to be optimised to maximise Practical Reserve Capacity(PRC) of a junction or to minimise delay.
  • LinSig can estimate a traffic Origin-Destination matrix for the network from traffic count data where no observed matrix is available.
  • Allows a traffic flow matrix to be assigned to the network using equilibrium delay-based assignment.
  • LinSig 3 is compatible with the LMAP (LinSig Model Auditing Process) procedure developed by Transport for London as part of their Modelling Guidelines. LMAP defines a standard procedure for auditing LinSig network models, making LinSig one of only a handful of network modelling packages with its own MAP procedure.
