This research project is a continuation of the first part of “Vehicle Positioning with Magnets in a Carriageway”. The purpose of this project is to investigate different magnetic background noises and disturbances, and to further investigate the magnetic markers pattern. The same magnetic field test rig as for the previous project was used. Different routes have been driven and a number of magnetic background noise sources have been found such as bridges, electrical cables, tramways and manhole covers. The magnetic markers pattern have been studied, both the type of pattern and if it is possible to encode information within the pattern, as well as how the lateral and the longitudinal pattern should be designed. The conclusions are that there are magnetic disturbances that need to be dealt with, either with stronger magnets or with filters. The standard magnetic marker, used for road without magnetic disturbance, will be a ferrite magnet with the dimensions of Ø40x30 mm that is embedded with the top of the magnet 10 cm below the road surface. The magnetic markers pattern is suggested to be a simple systematic pattern with the road marks as the base, with encoded information and at least three meters as longitudinal distance. The lateral pattern is dependent on the type of road. It is suggested that the density of markers used at the edge lines of the lane are halved compared to the density used in the centre of the lane. Demagnetization of the magnetic markers is considered not possible, but to dig up or shield the magnets could be used as a substitute method. The test road at Fagersta shows that the concept of embedding magnets in the road is feasible.
