Enable the Configuration Mode, then select Carriageways from the Configuration Tree. Select New from the Configuration Panel; this will open a list of new feature options. Select Carriageway.
The Carriageway Wizard window will appear, labelled as Create and Draw New Carriageway. Drag this window to one side, and the plumb line for your carriageway should be visible: a white horizontal line, with three nodal points.
You must now use the nodes of theplumb line in order to plot your carriageway - https://navtechradar.atlassian.net/wiki/spaces/TUN/pages/206602339/Creating+and+Editing+Entities#Plum-Line. The Open Street Map gives a visual guide to the position of the carriageway, but if your radar are live, they should also be transmitting visual data. Use a combination of the Open Street Mapand the visual data from the radar in order to accurately plot your carriageway.
The carriageway plotting tools are these: https://navtechradar.atlassian.net/wiki/spaces/TUN/pages/206602339/Creating+and+Editing+Entities#Carriageway

Return to the Create and Draw New Carriageway window. Now you can configure the carriageway and its Rules - these decide what objects and behaviours you wish the radar to detect.
Create Dual Carriageway: Select if your carriageway is a dual carriageway - traffic flowing in both directions.
Number of Lanes: The number of lanes on each carriage way - each direction of traffic.
Carriageway Separation (m): The distance of the barrier between the carriageways. Only applicable to a dual carriageway.
Lane Width (m): The width of one lane in your carriageway.
Section Length (m): The length of the segments your carriageway will be divided into in order to divide the surveillance of the carriageway equally between the radar.
Right Hand Drive: Select if your carriageway is in a country with right hand side drive.
Virtual Tracking Areas: Selected by default. This forces the software to generate appropriate tracking detection areas that match the carriageway. These areas are created dynamically when the software starts and when any changes are made to the layout of the carriageway.
Virtual Debris Tracking Areas: Selected by default. This forces the software to generate appropriate debris detection areas that match the carriageway. These areas are created dynamically when the software starts and when any changes are made to the layout of the carriageway.
Bidirectional Lanes: Select this option if you require a carriageway with bidirectional traffic, for example, Single Carriageways. This will then allow you to select which lane you wish to have with a reversed direction.
Default Rules: all AID rules are selected by default, however you can deselect the rules you don’t need.
Once you have selected the rules, click Next and you are given the opportunity to amend the key attributes of each selected rule:
Description: The object or action the rule applies to.
Alarm Description: A description of the alarm event, which will be displayed to the user.
Break Count: The number of times a rule has to be met before an alarm is raised.
Use Allowance Curve: The dynamic adjustment of the time it takes to generate an alarm based on how often the rule conditions are satisfied. This option is always recommended for ClearWay™.
Classification: What type of moving object.
Breaking Condition: Set the checking parameters for the rules speed value.
Min./Max. (m/s): Minimum and/or maximum speeds.
Once satisfied with your Rules' configuration, click Finish. Your virtual carriageway should now appear on the main display with sections showing based on the selected section length.
