Element Expanded Functional Requirements: HDOT-HAR-M Field Devices

Functional Area: Roadway Basic Surveillance
  1. The field element shall collect, process, digitize, and send traffic sensor data (speed, volume, and occupancy) to the center for further analysis and storage, under center control.
  2. The field element shall collect, process, and send traffic images to the center for further analysis and distribution.
  3. The field element shall collect, digitize, and send multimodal crossing and high occupancy vehicle (HOV) lane sensor data to the center for further analysis and storage.

  2. The field element shall respond to pedestrian crossing requests by accommodating the pedestrian crossing.
  3. The field element shall provide the capability to notify the traffic management center of pedestrian calls and pedestrian accommodations.
  4. The field element shall report the current signal control information to the center.
  5. The field element shall report current preemption status to the 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.
