Who uses TRANSYT?
TRANSYT is used across the globe by traffic engineers, traffic modellers, junction designers, students and tutors, working for local authorities; municipal, state and regional authorities; consultancies of all sizes from multi-nationals to the smallest businesses; universities; other educational establishments.

What can TRANSYT model?
TRANSYT can model mixed networks of signalised and unsignalised junctions.  Furthermore, when used in conjunction with a Junctions licence, it has the capability to predict the performance of priority junctions using standard ARCADY PICADY geometric data.

How TRANSYT works?
The core traffic model calculates a baseline Performance Index (an economic cost based on stops and delays) using manually entered traffic flows. TRANSYT then runs an optimisation process that adjusts the signal timings with the ultimate aim of reducing the Performance Index (PI) to a minimum. The TRANSYT optimisers are therefore seeking to produce multi-directional ‘green waves’ – a task that is impractical to attempt manually due to the complexity of trying to satisfy multiple objectives from different parts of the network.  Green waves on key routes can be easily favoured by applying constraints on the optimiser in the form of weightings and penalties.

A number of optimisers are provided and offer a choice between fast and highly-efficient modelling and slower modelling options which are able to provide better optimised timings. The optimisation process can be influenced by the application of a variety of weighting factors and limit penalties, which allows you to ensure the results match your exact criteria.

The simulation model provides a mechanism to evaluate the performance of a TRANSYT network for a given set of signal timings, for a wider variety of scenarios, including intermittent stages (i.e. non cyclic behaviour), blocking back, uneven lane usage, complex signalled approaches and controller streams on different cycle times.  This is achieved by modelling the random arrival patterns of individual vehicles over a series of trials, with results collated from the output of all the trials.
