Automatic detection and classification of safety barriers in road construction sites using a laser scanner

Lateral control of trucks is a challenging task, especially in demanding environments such as road construction sites as the lane width is reduced. Detailed and highly accurate maps, which contain traffic infrastructure objects, will provide important information for a lane keeping assistant for heavy duty vehicles. This paper presents a new approach for the automatic detection and classification of safety barriers in road construction sites using a laser scanner. This data then is used for the generation of a detailed road work map.
