1.2.7.4–Process In-vehicle Signage Data (Pspec*)
This process shall output data for use by in-vehicle signage equipment on vehicles traveling along the road (surface street) and freeway network served by the Manage Traffic function. This data shall be able to provide information from any of the types of indicators that are supported by the function (e.g., intersection controller, pedestrian controller, dynamic message sign (DMS), fixed signage data (e.g., stop sign, curve warning, guide signs, service signs, and directional signs), and dynamic information (e.g., local conditions warnings identified by local environmental sensors, variable speed limits, lane controls, roadway warnings). The process shall be responsible for its own fault monitoring, which shall check that output data is being sent and that it is an accurate representation of the input data. The process shall return operational status (state of the device, configuration, and fault data) to the Manage Traffic and Manage Maintenance and Construction processes which are responsible for the monitoring of roadside equipment faults.This Pspec is associated with the Roadway Subsystem*.
