1. A system for controlling traffic signalling devices for traffic management at an intersection of at least a first traffic route and a second traffic route, comprising:
a first radar sensor, configured to: transmit first radar signals, receive reflections of the first radar signals from road users within a first detection region on the first traffic route or on a first part of the intersection, and output, based on the received reflections of the first radar signals, first radar sensor detected first radar reflection signals that carry information related to first radar sensor referenced road user positions and/or first radar sensor referenced road user radial velocities;
a second radar sensor, configured to: transmit second radar signals, receive reflections of the second radar signals from road users within a second detection region on the second traffic route or on a second part of the intersection, and output, based on the received reflections of the second radar signals, second radar sensor detected second radar reflection signals that carry information related to second radar sensor referenced road user positions and/or second radar sensor referenced road user radial velocities,
wherein the first radar sensor and the second radar sensor are mutually configured to transmit the first radar signals and the second radar signals, as not interfering with one another,
wherein the first radar sensor and the second radar sensor are positioned at respectively different locations, or according to respectively different orientations, or both, and are further configured such that the first detection region and the second detection region overlap in at least one overlapping region; and
an electronic data processing device configured to:
receive the first radar sensor detected first radar reflection signals and the second radar sensor detected second radar reflection signals and at least partially combine the first radar sensor detected first radar reflection signals and the second radar sensor detected second radar reflection signals into combination detected radar reflection signals, and
control the traffic signalling devices at the intersection, based at least partially on the combination detected radar reflection signals.
