Active Safety Roadside Concrete Divider Surrogate Recommendation
J3234/2_202303
The scope of this document is to provide the design specifications/requirements/guidelines for concrete divider surrogates that represent actual concrete dividers to the in-vehicle sensors and can be used for performance assessment of such in-vehicle sensing systems in real-world test scenarios/conditions. Therefore, this document only includes the recommended concrete divider surrogate characteristics for automotive cameras, LiDARs, and/or radars. Concrete dividers are also known as concrete barriers [1].
Rationale:
Reducing road departure crashes is key for active safety systems since road departure crashes contribute to many road fatalities in the U.S. As more active safety systems—especially road departure mitigation systems (RDMS)—are introduced to the market, standard roadside object surrogates are needed for the automotive industry to test and evaluate RDMS systems. SAE International created an Active Safety Roadside Object Surrogate Target Task Force under the Active Safety Systems Standards Committee to study this topic and recommend roadside object surrogate design guidelines. The Roadside Object Surrogate Task Force aims to develop design specifications/recommendations for roadside object surrogates. The surrogates should represent real roadside objects to the sensors used in RDMS. They can be used for the performance assessment of such in-vehicle sensing systems in simulating real-world test scenarios/conditions. This document summarizes the findings and recommendations from the Roadside Object Surrogate Task Force.
