The road surveying system of the federal highway research institute – a performance evaluation of road segmentation algorithms

Abstract

Abstract. The construction of highways and federal roadways is subject to many restrictions and designing rules. The focus is on safety, comfort and smooth driving. Unfortunately, the planning information for roadways and their real constitution, course and their number of lanes and lane widths is often unsure or not available. Due to digital map databases of roads raised much interest during the last years and became one major cornerstone of innovative Advanced Driving Assistance Systems (ADASs), the demand for accurate and detailed road information increases considerably. Within this project a measurement system for collecting high accurate road data was developed. This paper gives an overview about the sensor configuration within the measurement vehicle, introduces the implemented algorithms and shows some applications implemented in the post processing platform. The aim is to recover the origin parametric description of the roadway and the performance of the measurement system is being evaluated against several original road construction information.

Road profile measurement using the two degrees of freedom response-type mechanism

“…Walker and Fernando 21 verified the ride statistics and defect locations determined from profile measurements with the traditional single-point and newer wide-footprint lasers. Streiter and Wanielik 22 recovered the origin parametric description of the roadway and the performance of the measurement system was being evaluated against several original roads construction information.…”
