Stakeholder Element Name Functional Area/Role Functional Area Description County of Maui Department of Public Works Maui DPW Field Devices Roadway Signal Priority This equipment package includes the field elements that receive signal priority requests from transit vehicles approaching a signalized intersection. The request for priority may or may not be granted, based on the overall traffic situation at the intersection, adherence to the schedule of the transit vehicle, etc. If priority is granted, the operation of the traffic signal is adjusted to give an early green indication or hold a green indication that is already displaying County of Maui Department of Public Works Maui DPW Traffic Operations Center TMC Multimodal Coordination This equipment package supports center-to-center coordination between the Traffic Management and Transit Management Subsystems. It monitors transit operations and provides traffic signal priority for transit vehicles on request from the Transit Management Subsystem. County of Maui Department of Public Works Maui DPW Traffic Operations Center TMC Signal Control This equipment package provides the capability for traffic managers to monitor and manage the traffic flow at signalized intersections. This capability includes analyzing and reducing the collected data from traffic surveillance equipment and developing and implementing control plans for signalized intersections. Control plans may be developed and implemented that coordinate signals at many intersections under the domain of a single traffic management subsystem and are responsive to traffic conditions and adapt to support incidents, preemption and priority requests, pedestrian crossing calls, etc. County of Maui Department of Transportation Maui Bus Fixed Route Dispatch Transit Center Signal Priority The equipment package monitors transit schedule performance and generates requests for transit priority on routes and at certain intersections. This equipment package may coordinate with the Traffic Management Subsystem to provide transit priority along the selected route. It also coordinates with the Transit Vehicle Subsystem to monitor and manage local transit signal priority requests at individual intersections. County of Maui Department of Transportation Maui Bus Fixed Route Vehicles On-board Transit Signal Priority This on-board equipment package provides the capability for transit vehicles to request signal priority at signalized intersections, ramps, and interchanges through short range communication directly with traffic control equipment at the roadside.

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.
