Hawaii Statewide ITS Architecture Functional Requirements: TMC Probe Information Collection Description: This equipment package collects, assimilates, and disseminates vehicle probe data collected from roadside beacons and centers controlling transit vehicles, emergency vehicles, toll collection points, and route-guided vehicles. It estimates traffic and road conditions based on the aggregated probe data and disseminates this information to other centers. Functional Requirements: The center shall collect traffic probe data from vehicles via roadside field equipment. The center shall collect road condition data from probe-equipped transit vehicles via transit management centers; the data may be aggregated and preliminarily processed at the sending center. The center shall collect traffic data from traveler information centers based on data from their subscriber vehicles; the data may be aggregated and initial link time calculations performed at the sending center. The center shall collect traffic data from toll administrative centers containing travel times between toll collection points for those vehicles equipped for electronic toll collection; the data may be aggregated and processed at the sending center. The center shall assimilate current and forecast traffic conditions based on collected probe data and distribute to other centers for dissemination to travelers. The center shall collect operational status for the roadside probe data collection equipment. The center shall collect fault data for the roadside probe data collection equipment for repair. Included In: HDOT-HWY Traffic Management Center

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.
