TRANSYT

TRANSYT is traffic engineering software developed by the Transport Research Laboratory.[1] It is used to model signalised highway networks and has the ability to model platooning.

Signalised roundabouts can be modelled using TRANSYT.

The current release is version 16.[2]

Method

The user inputs traffic flows on the relevant highway links which are controlled by signals. TRANSYT then optimises the green time for each signal to minimise the overall number of stops and delay time.

Worldwide use

The software was developed in the UK but has been adapted for use in other countries including Chile.[3]

In the US, the Federal Highway Administration adapted the product into TRANSYT-7F.[4]

Other software

TRANSYT's main competitor is LINSIG.
