SAE J3234/3_202507

The scope of this document is to provide the design specifications/requirements/guidelines for concrete curb surrogates that represent actual concrete curbs 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 curb surrogate characteristics for automotive cameras, LiDARs, and/or radars. This document is focused only on the concrete curb and not on the asphalt curb, which is not common. 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. Curb is an important roadside feature that should be considered for the road departure mitigation systems. There are currently no standard testing protocols and testing surrogates for curb detection. 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 curb surrogate design guidelines.
