For the Traffic violations detection module operation program module for identifying the plates and that is being set up is required (see Activating the program module, used for identifying the plates section).

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

To set the Traffic violations detection module, do the following:

1. Go to Traffic violations detection setting tab.
   

2. In Traffic lights signal dropdown list select Sensor object (see Intellect software package: Installing and configuring security system components guide) by signal of which the light of traffic light is detected (1).

   Information about Sensor object is presented in the Intellect software package: Installing and configuring security system components guide. Information about Traffic Light Detection is presented in The Traffic Light Detection software module setup section.

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

3. From the Alarm direction: dropdown list select the signal of traffic light detection on which the traffic violations detection is to be responded (2).
   1. Basic - to fix violation use the base signal of the traffic light.
   2. Left - to fix violation use the left arrow of the traffic light.
   3. Right - to fix violation use the rlght arrow of the traffic light.
4. Set the Draw stop line checkbox if it's necessary to overlay a stop line before the traffic light (3).
5. Set up the stop line displaying:
   5.1 Click Stop line settings (4). The window of the same name opens.
   
   5.2 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.
   
   5.3 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.
   5.4 Click OK.

6. Set up the displaying of violation areas:
   6.1 Click Setting violation areas (5). The window of the same name opens.
   
   6.2 Click Stop video to set the violation areas. As the result the frame on which it's necessary to set the violation areas, is displayed.
   
   6.3 Set the areas corresponding to following zones: before stop line. stop line, crosswalk, crossroads. To set the violation areas, click the points corresponding to the boarder of selected area in the video frame.
   6.4 Click OK.

   To remove the area click the button close to the corresponding button.

7. 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 (6).
8. In the Time of stop for recording field enter time (in milliseconds) that determines the time interval during which the vehicle should stay still while registering the Stop over crosswalk line violation (7).
9. In the Add.photos: fielld enter the number of photos made before the licence plate fixing and after its going out the control zone (8).

10. In the Interval: field enter time (in milliseconds) that determines the time interval between saving additional photos (9).

    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.

11. In the Number of pictures to trace alarm: field specify number of photos which will be stored from the moment of LP recognizing on the base recognizer to the moment of LP recognizing on the additional recognizer (10).
12. In the Additional recognizers: table specify additional LPR channels if it's required to use them along with the base recognizer (11).
    1. To add additional recognizer right-click in the Additional recognizers list, then click Add in the drop-down menu.
       
    2. From the LP recognition drop-down list select the additional recognizer (1).
       
    3. From the Sensor: drop-down list select the sensor which will send events about traffic light operation (2).
    4. From the State drop-down list select event from the sensor on which violation will be fixed (3).
    5. From the Alarm drop-down list select the corresponding type of violation (4).

    6. Click OK. The specified parameters will be added to the Additional recognizer table.
       

       To modidy recognizers in the rable, right-click the required recognizer to open the functional menu. Click Delete all button if the Additional recognizers table it to be cleared.

13. To save the changings click Apply.

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.
  

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.
