Physical Object: ITS Roadway Equipment

Roadway Traffic Information Dissemination

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
