Outbound-only broadcast vs bidirectional V2X
Are proposals using a one-way broadcast architecture (infrastructure-to-vehicle, no inbound from vehicles) considered responsive, given that it eliminates handshake latency and reduces cybersecurity exposure? Or does the topic require bidirectional V2X consistent with SAE J2735 / 3GPP Release 16 standards?

There is no preference for one-way or two-way broadcast architecture. SBIR Applicants are encouraged to select the communication architecture that best supports the proposed congestion mitigation approach, with emphasis on effectively disseminating operational advisories to reduce local congestion and prevent its propagation to surrounding areas.
