The Color Specification of Surrogate Roadside Objects for the Performance Evaluation of Roadway Departure Mitigation Systems
To ensure the safety of the vehicle and driver while testing the performance of road departure mitigation (warning (RDW) and road keeping assistance (RKA)) systems and to standardize the test environment, a set of roadside test surrogates are being developed, which includes grass, curbs, metal guardrail, concrete divider and traffic barrel/cones. This paper describes how to determine the representative color of these roadside surrogates. Firstly, 44,000 stratified road locations in the US were generated from randomly selected 820,000 locations based on road levels defined in ArcGIS which is a geographic information system for maps. Among them, 24,762 locations have Google street view images, which are used for the color determination of roadside objects. To mitigate the effect of the brightness for the representative color determination, the images in good weather, daylight and not under shade were manually selected.
