Extra 'set of eyes' for self-driving cars: Roadside radar sensors could reduce blind spots

Autonomous vehicles (AVs) are becoming increasingly common on roadways, but making them as safe as possible may entail going beyond the particular specs of the vehicles themselves to upgrading the roadway infrastructure. EyeDAR, a low-power millimeter-wave radar sensor roughly the size of an orange, could provide radar-equipped AVs with critical inputs about surrounding traffic, extending and enhancing the vehicles' sensing accuracy.
