178:. The LinSig traffic modelling was based on standard 'Y' value hand calculations which were widely used at the time for manually calculating traffic signal capacities and delays. This allowed the results of the software to be easily checked against existing manual calculations.

LinSig provides a matrix estimation facility to generate a network wide trip matrix from junction turning counts. This uses a combination of traditional entropy-based estimation methods together with customisations targeted at estimating matrices in smaller networks.
235:
LinSig uses a development of the Cyclic Flow
Profile traffic model which has been used extensively in the UK for many years. The Cyclic Flow Profile Model simulates the interaction between closely space junctions allowing coordinated signal timings to be modelled.

LinSig
Version 2 was the first version of LinSig to allow the modelling of more than one junction. A new network traffic model was introduced which allows the coordination of closely spaced traffic signal junctions to be modelled.

LinSig can model and optimise networks of several junctions as well as individual junctions. It is designed to model small groups of junctions in detail rather than larger networks covering entire towns.
219:
LinSig 3 changed from a link-based model to a lane-based model. It also allowed the user to model larger networks and provides new network modelling tools such as delay-based traffic assignment and

LinSig uses a traditional user equilibrium assignment to assign traffic to routes through the network based on delays calculated by the network model.
