Abstract

La présente invention concerne un système de contrôle sans pilote pour des véhicules en infraction de la loi à proximité de feux de circulation pour piétons. Plus spécifiquement, la présente invention concerne un système de contrôle sans pilote qui peut contrôler des incursions sur des lignes d'arrêt ou dans des passages pour piétons par des véhicules à proximité de feux de circulation pour piétons alors que les feux de circulation pour véhicules présentent un panneau d'arrêt. Selon un mode de réalisation, le système de contrôle sans pilote peut même contrôler des incursions sur des terre-pleins centraux (demi-tours dans des zones d'interdiction de demi-tour ou sous des panneaux d'interdiction de demi-tour, incursions arbitraires sur des terre-pleins centraux, etc.).
