Abstract
Surrogates for roadside objects, such as concrete dividers, can be used for vehicle testing. A surrogate for a concrete divider can have substantially the same size and/or shape as the concrete divider that the surrogate is mimicking. The surrogate can be configured to exhibit substantially the same characteristics as their actual counterpart concrete divider when sensed by one or more vehicle sensors (e.g., cameras, radar sensors, and/or LIDAR sensors). Such surrogates can be used to test autonomous vehicles, one or more vehicle sensors, a vehicle sensor system, and/or one or more vehicle system (e.g., a road departure mitigation system). The surrogates can be configured to withstand being crashed into by a test vehicle without being damaged and without damaging the test vehicle.
