TRANSYT Version History

Signal Design for Network and Junctions

TRANSYT is a macroscopic software package for designing, evaluating and modelling everything from single isolated road junctions to large mixed signal-controlled and priority control traffic networks.

TRANSYT
Area Change
UI (Fix) Network Diagram OpenGL compatibility issue solved (often associated with newer laptops and with Intel(R) HD Graphics Card Renderer)
UI (Fix) New User preference “Use hardware acceleration” which can be used to fix rare issues with the display of the network diagram
UI (Fix) Network diagram options: Lane “width” option now working as intended
FILES Library Files now heed Audit Trail file preferences
UI (Fix) Difficultly seeing all Demand Sets in Main Data screen now fixed
UI Enhancements and Fixes: Simulation “Signals Log”:

  • Flow sampling now works for all movements – not just those producing a controlling flow
  • Now only need to reference a source traffic stream, rather than the movement (i.e. source and destination) in order to display queues
  • Simulation “Signals Log”: Stage IDs now displayed
FILES Sample and Library Files edited to take account for possible use in Simulation Mode by ensuring traffic stream lengths are consistent (Auto-length used throughout)
UI Demand Set names are interpreted better to avoid duplicate names – e.g. references in name to AM and PM now automatically copied into “time period name”
UI New checkbox at bottom of OD Matrix “Entry Flows” tab, to allow a view of all traffic types, irrespective of whether or not there are any paths associated with these traffic types. This gives access to remove flows when they are no longer needed
UI Network Diagram – Retention of connections between locations and traffic streams improved when using the “Move Lanes” facility to split or join traffic streams
UI (Fix) When pedestrian crossings, nodes or controller stream IDs are renamed, Collection references are updated too, i.e. synchronised
LICENCES Polling of network licence improved – Grace period added to allow you to save your file before connection is lost
USER GUIDE Revised User Guide (Issue B): Miscellaneous minor corrections and additions.
