1. A computer implemented method for generating a collision warning, the method comprising:

  • defining, by the processor, a monitoring area monitoring by a warning device attached to a first object, wherein the monitoring area moves with the warning device;

    determining a change in a collision awareness factor in relation to the monitoring area, the collision awareness factor corresponding to an estimated awareness level of an operator of the first object of a likelihood of collision with a second object, wherein determining the collision awareness factor is based on a direction of movement of the first object, a velocity of the first object, an angular divergence of a focus direction relative to a movement direction of the first object, a number and a distribution of one or more objects within the monitoring area, a velocity of one or more objects within the monitoring area, a size and a shape of one or more objects within the monitoring area, a position and a proximity of one or more objects within the monitoring area, a current weather condition in the monitoring area, a light condition in the monitoring area, a time of day and a level of humidity in the environment of the first object;

    defining a warning zone in relation to the monitoring area based on the collision awareness factor; and

    generating a warning based on at least the second object being within the warning zone, and the collision awareness factor.
