Selecting the vehicle movement direction and distance

To select the vehicle movement direction and distance, do the following:

1. Go to the Speed traps server object.
   
2. From the Target drop-down list (1), select the vehicle direction relative to the Speed-trap device to determine its speed of movement:
   • Automatically − to automatically determine the vehicles speed moving relative to the Speed-trap device;
   • Oncoming − to determine the vehicles speed moving oncoming to the installed Speed-trap device;
   • Passing − to determine the vehicles speed moving from the installed Speed-trap device.

3. When configuring the Auto-URAGAN or AR-Auto software modules, from the Distance drop-down list (2), select the distance from the Speed-trap device to the place where the vehicle speed is determined.

   Note

   • The physical distance from the Speed-trap device to the place where the speed is determined is indicated in the documentation for the Speed-trap device.
   • The value of the Distance parameter is determined experimentally.
4. Click Apply (3).

The vehicle movement direction and distance is now selected.
