FUNCTIONAL REQUIREMENTS

Click on a Project Inventory element from the list above to view functional requirements.

Roadway Signal Controls

  • The field element shall report current transit priority status to the center.
  • The field element shall return traffic signal controller fault data to the center.
  • The field element shall return traffic signal controller operational status to the center.
  • The field element shall report current preemption status to the center.
  • The field element shall report the current signal control information to the center.
  • The field element shall control traffic signals under center control.

TMC Signal Control

  • The center shall maintain traffic signal coordination including synchronizing clocks throughout the system.
  • The center shall manage boundaries of the control sections used within the signal system.
  • The center shall implement control plans to coordinate signalized intersections based on data from sensors.
  • The center shall manage (define, store and modify) control plans to coordinate signalized intersections, to be engaged at the direction of center personnel or according to a daily schedule.
  • The center shall collect traffic signal controller fault data from the field.
  • The center shall collect traffic signal controller operational status and compare against the control information sent by the center.
  • The center shall remotely control traffic signal controllers.

OPERATIONAL CONCEPTS

Stakeholder Roles and Responsibilities
County of Maui Department of Public Works
Operate traffic signal systems for County of Maui owned intersections.
 

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.
