Functionality:

Functional Requirements*:

1. The field element shall include dynamic messages signs for dissemination of traffic and other information to drivers, under center control; the DMS may be either those that display variable text messages, or those that have fixed format display(s) (e.g. vehicle restrictions, or lane open/close).
2. The field element shall include driver information systems that communicate directly from a center to the vehicle radio (such as Highway Advisory Radios) for dissemination of traffic and other information to drivers, under center control.
3. The field element shall include pedestrian information systems under center control (e.g. warning pedestrians of a potential hazard, or providing mandatory instructions as to the availability of pedestrian access).
4. The field element shall provide operational status for the driver information systems equipment (DMS, HAR, etc.) to the center.
5. The field element shall provide fault data for the driver information systems equipment (DMS, HAR, etc.) to the center for repair.
