Requirements
# | Requirement |
---|---|
01 | The field element shall include dynamic message 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). |
02 | 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. |
03 | The field element shall provide operational status for the driver information systems equipment (DMS, HAR, etc.) to the center. |
04 | The field element shall provide fault data for the driver information systems equipment (DMS, HAR, etc.) to the center for repair. |
05 | The field element shall provide dynamic message sign information to roadside equipment for transmission to connected vehicles to support in-vehicle signing. |
06 | The field element shall include devices that provide data and status information to other field element devices without center control. |
07 | The field element shall include devices that receive configuration data from other field element devices, without center control. |
08 | The field element shall include dynamic message signs for dissemination of wrong way entry to drivers. |
09 | 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 wrong way entry to drivers, under center control |
