Automatic generation of high precision feature maps of road construction sites

Abstract

Road construction sites on highways are a demanding environment for drivers as the lane width is reduced. Especially for trucks, lateral control is a challenge. If the driver slightly drives over the lane markings, other vehicles cannot use the neighbouring lane. This leads to a reduction of the road capacity, thus causing traffic jams. A driver assistance system which supports the driver in the task of lateral control highly benefits from the use of accurate infrastructure (feature) maps. This paper presents an approach for the automatic detection, classification, and mapping of specific elements of road works like guard rails, safety barriers, traffic pylons, and beacons with laser scanners.
