Can I use TRANSYT to model a single isolated junction?

Question: Can I use TRANSYT to model a single isolated junction? I’ve always assumed I’d need to buy OSCADY PRO or an equivalent product to do this.

Answer: Yes! – You can use TRANSYT to model individual junctions. Since TRANSYT 14, TRANSYT has had the features and functionality to do this, and has the added convenience of being able to model both signalled and unsignalled scenarios in the same TRANSYT file.

TRANSYT 15 now offers a full set of priority objects, allowing unsignalled roundabouts, crossroads and T-junctions to be modelled within a network or on their own. These have the same data requirements as the standard ARCADY and PICADY models – The data is stored conveniently within the one network file. With TRANSYT allowing different cycle times to exist within the one file, TRANSYT has the capability to model different signalled and unsignalled scenarios within the one data file.

Note that OSCADY PRO still offers a simple alternative to using TRANSYT, at the expense of not containing any of the advanced networking capabilities that TRANSYT has. Both products will give similar results for the situations that they both can model. Of course, TRANSYT’s capabilties stretch well beyond that needed to model single junctions, and now includes easy-to-use phase-optimisation as well!

TRANSYT can be easily extended to model the effects of adjacent junctions if it subsequently becomes know that they are affecting the performance of your initial junction. The new merging function and set of library files, makes it very easy to merge individual junctions into other TRANSYT networks.

NEW: Follow the link to a video that provides a detailed guide on modelling a single signalised junction with TRANSYT 15 and also demonstrates how quickly a single junction can be built using the library file system.
