<p>The invention relates to a system for detecting the crossing, by a vehicle (3), of an effective line (L1) of a red light in a three-color traffic light (2), on a roadway (4) comprising at least four lanes, said system comprising at least two apparatuses (1) located on either side of the roadway (4), wherein each apparatus (1) comprises a pair of presence areas provided on each lane, for one to n lanes of the roadway (4); an image sensor (10), the field of view of which is capable of viewing at least the one to n lanes of the roadway (4) that are provided with at least one pair of presence areas, and thus defining a farthest lane in view on the roadway (4) as being the most distant lane from the sensor (10) among the one to n lanes of the roadway (4); and a processor (20) connected at least to each pair of presence areas and to the sensor (10), the processor being capable of detecting the presence of a vehicle (3) passing into a presence area, characterized in that the system comprises an additional presence area (31-1), connected to a first apparatus (1) and located in the farthest lane in view of the second apparatus (1), upstream from any presence area (21) connected to said first apparatus and located in the farthest lane in view of the apparatus (1). The invention also relates to a method implemented by the system.</p> |
