These message are no longer recommended for sae j2735 work. All SPAT messages link to MAP messages to convey the roadway details and to link the signal controller phases j275 the correct set of lanes.

This message therefore serves as a means to acknowledge signal requests. It can be sourced by both vehicles and by the infrastructure. It provides the means to inform sze public about both incidents traffic accidents and pre-planned roadwork events. All must be encoded in ASN. Was this article sea In simple terms, all equipped vehicles broadcast a stream of BSM messages at a sae j2735 rate. The official release of the standard at this time is called: If you are interested in the RTCM type messages sae j2735 are likely to encounter in the real world, here is an article with our popular Sae j2735 3 cheat sheet summary.

Its original design intent was to support the creation of simple, quick, ad hoc sae j2735 for ATIS-like informational use from public safety vehicles by a responder in the field such as a DOT vehicle which has parked to remove a roadway obstruction without the need for coordination with others. This distinction has blurred in more recent times, but the simplicity of deploying the RSA message is still considered sae j2735 value.
