Project Name:

Project Details: HIEMA Emergency Messages on DMS


This project will create a connection to allow HIEMA to have the ability to put emergency messages on HDOT-HWY DMS. HIEMA would not have direct control of the signs, but provide information or messages via a center-to-center connection.

Emergency Response Management

  • The center shall manage coordinated inter-agency responses to and recovery from large-scale emergencies. Such agencies include traffic management, transit, maintenance and construction management, rail operations, and other emergency management agencies.

Roadway Traffic Information Dissemination

  • 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).

TMC Incident Dispatch Coordination/Communication

  • The center shall exchange alert information and status with emergency management centers. The information includes notification of a major emergency such as a natural or man-made disaster, civil emergency, or child abduction for distribution to the public. The information may include the alert originator, the nature of the emergency, the geographic area affected by the emergency, the effective time period, and information and instructions necessary for the public to respond to the alert. This may also identify specific information that should not be released to the public.

TMC Traffic Information Dissemination

  • The center shall remotely control dynamic messages signs for dissemination of traffic and other information to drivers.

Stakeholder Roles and Responsibilities
Hawaii Department of Transportation - Highways Division
Coordinate incident and threat information with the Hawaii State EOC and the City and County of Honolulu EOC.
Provide traffic information to travelers via HDOT DMS equipment and GoAkamai.
Hawaii Emergency Management Agency
Provide evacuation and incident information to travelers in the state using the National Alert Warning System, the Hawaii Alert Warning System, Statewide Siren Warning System, and the Emergency Alert system.

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.
