High-intensity LED visual warning array The topic states advisories must be delivered to drivers and that the system should function effectively at low connected-vehicle *********** rates. Is a high-intensity LED visual warning array integrated into roadside infrastructure — visible to all vehicles regardless of V2X equipment status — considered a compliant advisory delivery mechanism under this topic, satisfying the low-*********** performance requirement by providing 100% vehicle coverage as a parallel channel alongside V2X RSA broadcast? The topic focuses on innovative systems integrating AI, cloud-edge, and V2X, aiming to mitigate real-time congestion in a local or regional area, encompassing multiple intersections and roadways. SBIR applicants are encouraged to incorporate relevant technologies to satisfy the solicitation under the scenarios of low connected vehicle rate.
