  • introducing horizontal and vertical signaling equipment, including changes to the adjacent road and motorway networks,
  • creating a multipoint unit to link the equipment,
  • setting up operating equipment (road signs, cameras, traffic lights, special signs, etc.),
  • upgrading the roadside operations, safety and assistance control center to integrate the shared-access lane.
