The invention concerns a signal alignment test performed by a processing unit 6 that can be used to automatically check correct configuration of signage 8 on a stretch of railway track or road. The method comprises: receiving image or video data from a section of road or track; identifying from the data, shapes as target signs for which to calculate attributes (e.g. alignment, orientation); generating output data about the set-up of the target signs. The method could include taking data from a camera mounted on the vehicle or locomotive 4. The processing unit contains software or firmware to calculate deviations in signage data such as face angle, largest perceived surface area, and effective luminosity, for each sign viewable on the given stretch of track or road. Claims are also included for a system having a memory that stores reference image or video data indicative of an acceptable condition of the signage. By comparing images recorded by the camera to the stored data the system can issue an alert if the signage is in an unacceptable condition.
