CHARACTERIZATION OF ROAD EDGE MARKINGS IN SUPPORT OF ROAD-DEPARTURE PREVENTION SYSTEMS

The visual properties of painted lane markings were characterized through a field measurement exercise using a specialized trailer apparatus. The class of markings examined consisted of the continuous white stripe defining the boundary between the right lane and the shoulder of the road. Stripe width, reflectance, and contrast with lane and shoulder regions were quantified for over 6000 video images taken along a 600 mile (964.5k) sample of Michigan highways. Data indicate that slightly less than 82% of the stripes surveyed had widths in the of 8 to 15cm, with wider stripes outside this range being more common than narrower stripes. Stripe reflectance exhibited a bimodal distribution with primary modes around 28% and 60% reflectance values. Application of the data set to an existing road-follower algorithm is discussed.
