FUNCTIONAL REQUIREMENTS

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

MCM Infrastructure Monitoring

  • The center shall report infrastructure repair needs to the maintenance management system.
  • The center shall provide current infrastructure conditions information to the asset management system.
  • The center shall collect current maintenance and repair needs from the asset management system and correlate this data with data collected through infrastructure monitoring systems.

On-board Transit Signal Priority

  • The transit vehicle shall prevent a priority request from being sent when the transit vehicle cannot use the priority (e.g., when the transit vehicle makes a passenger stop on the approach to an intersection).
  • The transit vehicle shall send the schedule deviation data and status of priority requests to the transit vehicle operator and provide the capability for the transit vehicle operator to control the priority system.
  • The transit vehicle shall send priority requests to traffic signal controllers at intersections, pedestrian crossings, and multimodal crossings on the roads (surface streets) and freeway (ramp controls) network that enable a transit vehicle schedule deviation to be corrected.
  • The transit vehicle shall determine the schedule deviation and estimated times of arrival (ETA) at transit stops.

Roadway Signal Priority

  • The field element shall respond to signal priority requests from transit vehicles.
  • The field element shall respond to signal priority requests from transit vehicles.

Transit Center Signal Priority

  • The center shall provide transit operations personnel with the capability to control and monitor transit signal priority operations.
  • The center shall define business rules that govern use of transit vehicle signal priority, communicate these rules to the transit vehicle, and monitor transit vehicle requests for priority at signalized intersections.
  • The center shall send requests for priority along routes or at intersections to traffic management.
  • The center shall analyze transit vehicle schedule performance to determine the need for priority along certain routes or at certain 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.
