Playback Tracks

Introduction

This section covers the Playback Track function: how to create and configure Playback Track, and their potential uses.

Contents



Overview

A Playback Track is a essentially a track clone, designed by the user in order to simulate incidents, test areas and classification parameters. Obviously, it is preferable to create the specific situation and conditions for testing rather than have to wait on the off-chance for the desired result from actual data.

Creating a Playback Track

Change Track Engine Provider Type

Before a Playback Track can be created, it is necessary to change the Track Engine Provider Type, as a Playback Track cannot function alongside tracks from live data. To do this:

  1. Under the Topology tab, select the Track Engine Window that contains the Radar Sensor allocated to the stretch of carriageway the Playback Track will travel along.

  2. In the Topology Panel, select Edit, and then open the dropdown list of Provider Type options.

     

  3. Select Playback All Track, then select Save.

Create a New Playback Track

Now a Playback Track can be created:

  1. Under the Config tab, the PPI Display should now include a Playback Tracks Controls Panel.

     

  2. In the Entity Panel, select Playback Tracks, and then select New in the Configuration Panel.

     

  3. Select New Playback Track to open the Create New Playback Track Wizard.

     

  4. Name the Playback Track, then select Finish.

     

  5. The Playback Track will appear on the PPI as a horizontal plum line:

     

  6. Use Standard Creating and Editing - to edit the plum line into the pathway the Playback Track will take, along the carriageway.

     

  7. Configure the Playback Track settings in the Configuration Panel (see below), then select Save.

     

  8. By default, the Playback Track pathway will not be hidden; appearing as a dashed red line on the PPI:

     

  9. Next, use the Playback Tracks Controls Panel to Play, Pause, Rewind and Stop the Playback Track.

     

  10. It is possible to create multiple playback tracks played simultaneously:

     

  11. To enable or disable particular tracks, select or deselect the Enabled option and Save:

     

When amending a playback track, the previous saved position will be displayed as a pink dashed line.

When setting up playback tracks for ClearWay™ you will need to enable Distribute Tracks on all of your radars. Please refer to for information.

Cloned Playback Track

A Playback Track can also be cloned from a track's history during a Track Query -:

  1. In the Results Panel, select the history of the track to be cloned.

     

  2. The Track Details window will open. Select Clone Track.

     

  3. The new Playback Track will appear in the Configuration Tree and on the PPI Display. It will be named after the track it was cloned from.

There is a limit to cloning Playback Tracks from track histories: only tracks with fewer than 200 sightings can be cloned.

Configuration

These are the settings for Playback Tracks that appear in the Configuration Panel.

Settings

Name: The name of the Playback Track.

Channel: The channel the Playback Track is assigned to. The Playback Track pathway must be drawn on the carriageway assigned to the same channel, or it will not run.

Refresh Period: The time period between sightings.

Enabled: Select this to enable the Playback Track.

Loop: Select this to constantly replay the Playback Track.

Record Track: Select this to keep a record of the track.

Classification: Select one of the entities from the drop-down list; e.g. Large Vehicle.

Source Type: Select the Source Type from the drop-down list.

Tag: The name of the tag of one has been added.

Default Speed (m/s): The speed of the Playback Track.

Speed Variance (m/s):

Course Variance (Deg):

Default Size Azimuth (m): The size of the Track along the azimuth.

Default Size Range (m): The size of the Track along the range.

Default Signal Strength: The strength of signal the Playback Track returns.

Default Weight: The weight of the Track.

Default Hight: The height if the Track.

Hide: Select this to hide the Playback Track pathway on the PPI Display.

Colour: The colour of the Playback Track pathway.

Layer: Select this to choose the Layer.

Delta

Effective

Speed

The increase/decrease in speed at this waypoint from the default speed setting.

Default Speed +/- Delta Speed = Effective Speed

Size Azimuth (m)

The increase/decrease in size along the azimuth at this waypoint from the default size azimuth setting.

Default Size Azimuth +/- Delta Size Azimuth = Effective Size Azimuth

Size Range (m)

The increase/decrease in size along the range at this waypoint from the default size range setting.

Default Size Range +/- Delta Size Range = Effective Size Azimuth

Strength

The increase/decrease in signal strength at this waypoint from the default signal strength setting.

Default Signal Strength +/- Delta Signal Strength = Effective Signal Strength

Weight

The increase/decrease in weight at this waypoint from the default weight setting.

Default Weight +/- Delta Weight = Effective Weight

Height (m)

The height of the track.

 

Linear Change

Select this box to enable a gradual between waypoints with different deltas, instead of a terraced change.

-

Stop Time (s)

The period of time the track will pause at this waypoint.

-

Coast

Shows if the track was coasting at this waypoint.

 


 

Safety is everything.
