ARCADY 8/Junctions 8 Version History


Junctions 8.0.6, 26th Nov 2015 [CURRENT MAINTENANCE VERSION]

UIVarious fixes to make the importing of Junctions 9 files more reliable.   Please note that there is a difference in the way that Junctions 8 and Junctions 9 handle Analysis and Demand Set IDs.   Junctions 9 allows the IDs to be set by the user to any value, whereas Junctions 8 sets them automatically according to an internal numbering system.  If you import a Junctions 9 file where Analysis/Demand Sets have been deleted/renumbered/re-ordered, the remaining sets may appear in a different order in Junctions 8.  Any references to IDs such as Demand Set Relationships will be blanked during the import and will need to be re-entered manually in Junctions 8.  Please contact TRL for further advice if necessary.

Junctions 8.0.5, 19th June 2015 

UIFiles saved from Junctions 9 (.j9 files) can be imported via the File>Import menu or by dragging the file into Junctions 8.  The import will ignore any data or features of the file that cannot be used in Junctions 8.  Complex files, or those that make heavy use of Junctions 9 features may fail to import; in such cases please contact TRL for advice.   
UIFixed some problems where certain data fields were incorrectly invisible or disabled
UIIf the Report Viewer or Junction Diagram are taken outside the main application window (this is the default for the Report Viewer) they now remain on top of the main window at all times.  Added a Print menu to the Report Viewer (also available by right-clicking the report).
UIFixed bug with PICADY 5 export (CT29)
UIThe lower limit for the major carriageway width for PICADY junctions is now 3m.  Widths in the range 3-6m are intended for use at one-way junctions; for two-way junctions a width of 6m or greater should be entered.
MODELFix to the way certain PICADY stream delays are reported when pedestrian crossings are present.


Junctions 8.0.4, 24th March 2014 


Inclusion of ARCADY Lite as a new product within Junctions 8.   ARCADY Lite is a simplified version of ARCADY, primarily aimed at American users.  It offers the ARCADY and HCM 2010 roundabout models, in a streamlined UI, with built-in window layouts that show all basic data on screen at the same time. It also has various other enhancements such as the ability to set alternative intercept corrections without needing to use the full Analysis Sets system. ARCADY Lite can be activated by purchasing an ARCADY Lite licence and registering this instead of the full ARCADY module.   If the full ARCADY module is registered, then ARCADY Lite can optionally be used on a per-file basis.


The other changes listed below apply to all version of Junctions 8. 
UIWindow Layouts now store the contents, orientation and column widths of Data Grids, as well as their positions.  This makes it much easier to set up custom views of data and screens for subsequent use at any time.
UIWindow Layouts can now be imported and exported, so that they can easily be exchanged with colleagues 
UINew user preference to use abbreviated terms throughout UI - e.g. “E” instead of “Entry Width”, “Res Cap” instead of “Residual Capacity”, etc.   In this mode many screens and data grids occupy less space on the screen, making more compact layouts possible.
UIData Grids in rotated mode (fields as columns) allow widths of all columns to be adjusted evenly, using a width slider at the top of the window
UIData Grids in rotated mode (fields as columns) now allow adding/deleting items by right-clicking column headers
UIData Grids in rotated mode (fields as columns) now highlight active item, and can make an item active by left-clicking column header
UINew user preference to control whether new Data Grids should be shown in rotated mode
UINew user preference to control whether the Summary Results screen is automatically shown after running the traffic model.    Window layouts that already contain results data grids can hence be prevented from launching additional results screens.
UINew user preference to control whether new files should use UK or US units 
UINew optional ‘quick set-up’ screen can be used to set basic options for new files
UIVarious minor bug fixes / enhancements
MODELFixed bug where PICADY stream intercept adjustments would be applied even when inactive
MODELFixed bug where LEVELS profile would fail if peak occurs before end of first time segment
MODELQueue variations (Q95) are now available with PHF profile
MODELFixed bug where Summary Results would show blank results if using multiple analysis sets containing different PICADY geometries leading to different PICADY stream definitions.
MODELVarious minor fixes


Junctions 8.0.3, 13th Nov 2013 

GUIThe link between ARCADY and AutoTrack has been superseded by a link between ARCADY and Autodesk® Vehicle Tracking. This follows the acquisition of Savoy Computing by Autodesk®. The actual operation of the link is unchanged. The requirement to register a licence for the link has been removed. Existing users of ARCADY-AutoTrack Link are still supported
GUIEntry Lane Simulation: if a time segment is selected via the main dropdown, the simulation visualisation time now jumps to the END of the time segment (previously jumped to the start). E.g. if the 08:15-08:30 time segment is selected, the visualisation will show info for 08:30:00, since all other results for a time segment refer to the values at the end of the time segment.
GUIEntry Lane Simulation: the lane configuration screens now respond to Copy and Paste.
GUIClicking through cells in the Turning Counts screen now highlights the movement in the Junction Diagram
REPORTSFixed bug where reports showing all analysis/demand sets could differ from reports showing individual sets
GUIFixed problem with ‘Hide priority streams’ option with LR staggers.
GUIVarious minor fixes
MODELVarious minor fixes



Junctions 8.0.2, 14th Feb 2013

INSTALLATIONNetwork administrators can now automatically set up each Junctions client installation to start in Network Licence mode.  For details, please see the SECURITY REGISTRATION document included with the product.
GUIVarious improvements re UAC and signing on Windows 7/8
GUIDemand set relationships are now easier to use:  turning counts and vehicle mix for the resultant demand set are now calculated automatically.   This means that it is now straightforward to set up demand set relationships with common scenarios such as ONE HOUR profile types.  (Previously it was necessary to manually enter the turning counts for the resultant set, which in many cases negated the convenience of using demand set relationships.)
GUIDemand set relationships can now be used with linked roundabouts 
GUIMax number of analysis/demand sets increased from 20 to 30
GUITime Segment Results>Advanced is now hidden from the user (contained various internal flags which are not needed by the user)
GUIEntry Lane Analysis screen is now resizable, making it easier to work with grids of lane movements.
GUIARCADY-AUTOTRACK LINK:  no longer shows the ‘Calculating…’ dialogue during each AutoTrack-commenced run.   This makes it more convenient to leave ARCADY minimised while connected.
GUIIf running on Windows 8, the default Reader app will be used to launch PDFs if necessary.  However, we strongly advise installing a separate desktop PDF reader, which Junctions will use in preference.
MODELFixes to capacity calculations of pedestrian crossings at T-junctions
MODELChange to capacity calculation of one-way PICADY roads.   (Advice for manual treatment of one-way roads has also changed; please see Knowledge Base.)
MODELEntry Lane Analysis now makes better use of multi-core processors which means that the UI is more responsive during simulation runs.  (Actual time taken to run simulation is mostly unaffected.)
MODELPICADY results now behave more consistently when very low flows are reduced to zero
MODELPICADY results now include a warning about traffic blocking back into the junction (this is present in PICADY 5 but was missed out of the PICADY 8 implementation)
REPORTSReports now correctly show the name and path of the file being run.   (This was not being written in some cases).  Reports are now correctly saved in the appropriate destination folder as set in user preferences.
REPORTSFixes to labelling of sections
REPORTSWhen using the Convert>Save as PDF option, the generated PDF report now has improved pagination so that content is less likely to break across pages.
DIAGRAMJunction diagram:  some lines and other elements in 8.0.1 were very thin/faint and difficult to see; this has been corrected.
DIAGRAMWhen in Entry Lane Analysis or HCM modes it is now possible to right-click on the entry side of an arm (pale blue line inside one of the lanes) to access the arm properties and the Add new Section option.   This makes it possible for lanes to bend or curve as required.  This is described in section 14.4.3 of the User Guide but previously did not work correctly.
ALLVarious other minor bug fixes and enhancements.
