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

1. Go to the Speed traps server object (2).
   
2. From the Target drop-down list (3), 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 CARMEN-Auto software modules, from the Distance drop-down list, select the distance from the Speed-trap device to the place where the vehicle speed is determined.

   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.
