The description of the Area editor window interface elements is presented in the table below.

NumberInterface elementDescription
1Workspace

Displays the information about the areas on top of a video image

2High Accuracy Mode flagNot used in this version
3Start Time Of The
Clip
field

Not used in this version.

Note. It specifies the start time that will be used as the base for sending the timestamps. The frame timestamp is calculated as the TIME_STAMP = (START_TIME + FRAME_NUMBER * 1 / FPS), where FPS means “Frames per second”, and FRAME_NUMBER is the zero frame index

4Freeway flag

Enables/disables the freeway mode. Should be activated for a freeway where the vehicles are moving fast and non-stop

5FailSafe Detection ON flag

Enables/disables the video signal availability check

6Number of Zones

Displays the number of zones in the workspace

7Add New Zone buttonAdds a new zone to the workspace
8Delete Current Zone button

Deletes the current (highlighted in red marks) zone from the workspace

9Enabled flag

Enables/disables the processing of the selected zone

10Directionality drop-down list

Enables/disables the vehicle direction check:

  • Hard − detection of vehicles will be limited to the cars that move in the right direction, or the cars that stopped in the zone;
  • Soft − maintains a high level of detection of vehicles that are moving in the wrong direction, but slightly weakens the detection;
  • Off − vehicle direction check is disabled
11Shadow Suppr. drop-down list

Controls the shadow suppression algorithm:

  • Soft − soft shadow suppression;
  • Hard − hard shadow suppression;
  • Off − disables the shadow suppression algorithm
12WD Check flagChecking Wrong Direction. Enables/disables the visualization of cases when the vehicle moves in a direction totally opposite to the originally set direction (orange color)
13Cars Per Zone drop-down list

Allows specifying the number of vehicles that are "visually" in the zone, if you place them one after another. For detection of stopped cars usually a value of 1 is specified, and the zone of the corresponding size is automatically set, and the entire roadway is filled with these zones. As a result, it becomes possible to create wide, stretched zones that cover the whole or most of the lane compared to when you create several zones of the “single vehicle”.

  • AutoDetect − automatic detection;
  • 1 Car − 1 vehicle;
  • 2 Cars − 2 vehicle;
  • 3 Cars − 3 vehicle;
  • 4 Cars − 4
vehicle12Lane Type drop-down list

It is used to configure the type of detection zone (to configure the response of the algorithm depending on the expected behavior pattern):

  • Left turn − a significant amount of staying (waiting for the green traffic light) traffic is expected;
    • Right Turn − (North America specifics) - minimum
    • vehicle
    stop time, etc.;

    Note. The Shoulder parameter is used to configure “Roadside” type of detection zones (detection of vehicles that have stopped because of alleged accident)

    13Shadow Suppression drop-down list

    Controls the shadow suppression algorithm:

    • Soft − soft shadow suppression;
    • Hard − hard shadow suppression;
    • Off − disables the shadow suppression algorithm
  • Shoulder − not used in this version.

    Check Wrong Direction flag

    Enables/disables the visualization of cases when the vehicle moves in a direction totally opposite to the originally set direction (orange color)

    15
    Suggested Cars Per Zone fieldSpecifies the estimated number of vehicles that are "visually" placed in the zone. It is directly associated with the Cars Per Zone parameter
    16Shoulder IsBusy flag

    Not used in this version.

    Note. Enables/disables the display of information and events based on whether the lane of the Roadside type is occupied for more than a certain number of seconds. This type of detection zone is suggested to be installed in the curb area if the analytics are required to detect the cases of roadside occupancy at the installation site of the detection zone by a car, presumably in an emergency

    17Min Busy MSec field

    Not used in this version.

    Note. It is directly associated with the Shoulder IsBusy parameter, and is used to set a time threshold (in seconds) to start sending messages

    18
    15Sensitivity sliderIndicates the sensitivity level of the vehicle detection in the selected area
    19
    16Work Mode drop-down list

    Indicates the operation mode of vehicle detection:

    • Optimal (default) − provides the most balanced and accurate vehicle detection;
    • MinFD
    −
    •  − provides a good level of vehicle detection, with less false triggerings;
    • MaxTD
    −
    •  − provides the maximum level of vehicle detection, but sometimes it can produce additional false triggerings
    20
    17Lane ID fieldIndicates the identifier of the lane associated with the selected zone. This information is used by the IntelliVision vehicle detection
    module
     module for better detection accuracy
    21
    18Auto reset time fieldIndicates the time in minutes used to reset the zone if the zone is in the busy state longer than the specified time (default = 0, which means disabled)
