Road tracing is a promising technique to increase the efficiency of road mapping. In this paper a new road tracing algorithm is presented. Road positions are computed by matching the average grey value profile of a reference road segment with profiles taken from the image. The road parameters are estimated by the recursive Kaiman filter. By utilizing the prediction step of the Kaiman filter the road tracer is able to continue following the road despite temporary failures of the profile matching that are due to road crossings, exits and cars.
