1. An apparatus for controlling traffic lights of a crossing, a road of a first direction and a road of a second direction intersecting at the crossing, the apparatus comprising:
- a detecting unit configured to detect jam states of the road of the first direction and the road of the second direction for predefined regions in monitored images of the road of the first direction and the road of the second direction;
a counting unit configured to respectively count vehicles on the road of the first direction and the road of the second direction passing the crossing in the predefined regions within a predefined period of time; and
a controlling unit configured to control traffic lights of the road of the first direction and the road of the second direction based on the jam states of the road of the first direction and the road of the second direction and according to jam levels of the road of the first direction and the road of the second direction, weights assigned to the road of the first direction and the road of the second direction and a number of the vehicles on the road of the first direction and the road of the second direction passing the crossing within the predefined period of time.
