A system and method for securing and verifying transmitted traffic data. A transmitter may send a transmission via a radio signal including traffic data through or from hardware installed in a traffic control cabinet adjacent an intersection or other roadway feature of interest. The transmission may be signed with a private key. A receiver associated with a vehicle may receive, in addition to the transmission, a public key (e.g., via a data network) for use in verification of the authenticity of the transmission.
