1.2.4.3–Output In-vehicle Signage Data (Pspec*)
This process shall format and output data for use by roadside processes in creating in-vehicle signage. The process shall be capable of outputting any information that would typically be output on a dynamic message sign (e.g., current incidents, planned events, wide area alerts, evacuation information, shelters, road closures, highway rail intersection status), traffic indicator outputs, fixed signage (e.g., Stop signs, yield signs), and local conditions warnings identified by local environmental sensors. The data shall be structured by this process so that it can be output by each roadside process to vehicles for use by in-vehicle signage equipment.This Pspec is associated with the Traffic Management Subsystem*.
