Kauai Regional ITS Architecture Functional Requirements: Roadway Traffic Information Dissemination Description: This equipment package includes field elements that provides information to drivers, including dynamic message signs and highway advisory radio. Functional Requirements: 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). 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. 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). The field element shall provide operational status for the driver information systems equipment (DMS, HAR, etc.) to the center. The field element shall provide fault data for the driver information systems equipment (DMS, HAR, etc.) to the center for repair. Included In: HDOT-HWY-K Field Devices Kauai DPW Field Devices

The Hawaiian language uses two diacritical markings. The 'okina is a glottal stop; and the kahako is a macron. The State of Hawaii strongly encourages the use of Hawaiian diacritical markings. The National ITS Architecture tool, Turbo Architecture, does not allow for the Hawaiian diacritical markings to be input and as such, customized service package diagrams, operational concepts and other outputs from Turbo are unable to reflect the diacritical markings. To ensure consistency in this ITS Architecture website, no Hawaiian diacritical markings will be used.
