Claim 8:
9. An apparatus comprising at least one processor and at least one memory that contains program code, wherein the at least one memory and the program code are configured to use the at least one processor to cause the apparatus to perform and/or control at least:
obtaining light intensity information that is indicative of an intensity of light emitted from at least two light sources positioned along a segment of a road and detected by a light sensor;
converting the light intensity information into data representative of the variation in the intensity of light;
detecting light emitted from the at least two light sources while moving along at least part of the segment of the road, wherein the data representative of the variation in the intensity of light comprises a temporal frequency at which the intensity varies at least while moving along the part of the segment;
obtaining information indicative of a mutual distance between the at least two light sources wherein the mutual distance is based on at least information indicative of a length of the segment of the road; and
obtaining information indicative of a velocity of at least one first apparatus and/or of at least one further entity based at least on the data representative of the variation in the intensity of light.
