For correct operation of the Traffic violations detection module configure the synchronous video camera from which frames and video fragments will be saved (detailed information about configuring the sychronous video camera is presented in the Selecting the video cameras to work with the LPR channel page).

Note
titleAttention!

The Traffic violations detection is in full operation with the Auto-Uragan recognition module. Only the Red light violation will be recognized while join operation of the Traffic violations detection module and the Carmen recognition module. Other violations will be inaccessible.

 

The Traffic violations detection object is created on the basis of LPR channel object.

    For correct operation of the Traffic violations detection module disarm the corresponding Sensor object.

  3. Set the Draw stop line checkbox if it's necessary to overlay a stop line before the traffic light (2).
  4. Set up the stop line displaying:
    4.1 Click Stop line settings (3). The window of the same name opens.

    4.2 Click Stop video to set the stop line. As the result the frame on which it's necessary to set the stop line, is displayed.

    4.3 Set the stop line. To set the stop line, click the road edge in the image, press the left mouse button, drag the cursor to another edge of the road in the video frame.
    4.4 Click OK.
  5. Set up the displaying of violation areas:
    5.1 Click Setting violation areas (4). The window of the same name opens.

  6. In the Delay in violation registering field enter time (in milliseconds) that determines the time interval after which after switching on a red light the violations will fix (45).Enter
  7. In the number of frames that will be saved in database in the The number of frames to save field at the running a red light (5). Only 10 frames are saved in database in case of value more than 10 is specified.Enter Time of stop for recording field enter time (in milliseconds) that determines the time interval of frames for saving in the Frame saving interval field at the running a red light during which the vehicle should stay still while registering the Stop over crosswalk line violation (6).
  8. From In the Type of violation drop-down list select the type of traffic violation that will be specified in the caption to the alarm while the Stop violation is registered Number of add.photos: fielld enter the number of photos made before the licence plate fixing and after its going out the control zone (7).

    titleNote.

    The following violation types are available: Stop over stop line and Stop over crosswalk line.

  9. Enter the number of frames that will be saved in database in the The number of frames to save field when the Stop violation is registered (8).
  10. Enter In the Interval: field enter time (in milliseconds) that determines the time interval of frames for saving in the Frame saving interval field when the Stop violation is registered (9between saving additional photos (8).

    Note
    titleAttention!

    For correct operation of synchronized frames recording set the checkbox in Automatic recording on LPR channel object setting panel and set value of time that is bigger than the product of Number of frames for saving and Interval of frame saving parameter points.

The Traffic violations detection module setup is complete.

Logic of working the Traffic violation detection is explained in the following example.

Example. The vehicle is going from zone 1 to zone 2. Crossing over stop line violation will be registered in case of the vehicle is not crossing the boarder of zone 3 during the delay in violation registering. Checking for Stop over crosswalk line violation is performed in case of vehicle is crossing the border of zone 3. In such case vehicle stay still during the time of stop for recording and Stop over crosswalk line violation is registered or the vehicle is crossing the boarder of zone 4 and Crossing over crossroads on red light violation is registered.

The installation diagram of video cameras for violations detections by all directions of signaled crossing depending on the number of lanes is follows.

Several cameras are used for this purpose:

  • Main camera - by one on each lane focused on the crossing and they detect and recognize license plates of vehicles entered to the crossing. Vehicles are moving to cameras.
  • Additional, overview camera directed behind vehicles entered to the crossing (vehiles are moving from the camera). The traffic light with the red signal is also in the field of camera view.
    Image Added

The Auto-Intellect software package receives signal from traffic light controller that the red signal enabled. After this signal record by all cameras started. For each vehicle entered to the crossing the following are detected:

  • image of vehicle and its license plate;
  • recognized vehicle LP (in the text mode);
  • image confirming that the red signal is enabled and vehicle is located on the forbidden place is detected by additional, overview camera.

The Auto-intellect software package allows combining of umlimited number of crossings in the one photo-video detection system of moving on the red signal of traffic light. Data about all detected violations on all crossings are automatically passing to the integrated database.
