Is there a way of graphically representing queue/delay? A visual depiction would be useful when comparing scenarios.
This depends on what type of junction you’re modelling and what mode you’re in, but here are some tips:

  • The Junction Diagram screen has several overlays and graphical modes. For instance, after running a file, go to to the Junction Diagram and click Overlays>Show Queues>End Queues. This will show red bars on each junction arm corresponding to the time segment queues. These will change as you select different time segments or Demand Sets. To change the scale of the bars, click Show>Scale, then right-click on the scale line and choose Adjust Scale.
  • You can see a graphical depiction of the flows through the junction by clicking Overlays>Flows By Entry, and then choosing Flows>Actual Flows. The widths of the coloured lines will correspond to the calculated throughput for each movement. The relative widths can be adjusted by going to the Options screen and then adjusting Graphical overlays>Overlay width.
  • If using Lane Simulation mode, there are various animations and overlays available, when the Junction Diagram is shown. These are available at the bottom of the Lane Simulation screen. Drag the Time slider to see the queues at different times.
  • Various other overlays are available in the Junction Diagram; please see the User Guide for details.
  • If generating reports in Junctions, the report will contain one copy of the diagram, which will include any currently selected overlays. It is not possible for reports to show the diagram separately for each Demand Set. However, you can copy the diagram by right-clicking in it and choosing Copy and can then paste it into your own report, for any Demand Set.
  • You can also use the Analyser Screen to show charts of queue lengths or any other output. For example, click the Analyser button on the main vertical toolbar, then go to the Time Graph tab, and use the Common time graphs menu to choose one of the built-in graphs. (See the User Guide for details of how to select other items.) Then press the Line or Bar button at the top to generate a chart showing how the queue (or whichever output you chose) varies over time.
  • If available, you can click the Save Graph button at the bottom of the Analyser screen to save graph definitions. When generating reports, you can then tick the Graphs option in the Report Viewer, choose the graph, and then refresh the report. The graph will then be generated (for each Demand Set, if required) whenever you refresh the report.
