Project Name:

Project Details: HDOT-AIR-K Airport Secondary Entrance

Description:

Should a second entrance to the Lihue Airport be constructed, ITS field devices (e.g., CCTV cameras, traffic sensors, dynamic message signs) could be included in the project design in coordination with HDOT-HWY-K.

Collect Traffic Surveillance

• The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements under remote control of the center.
• The center shall monitor, analyze, and distribute traffic images from CCTV systems under remote control of the center.

Roadway Basic Surveillance

• 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.
• The field element shall collect, process, and send traffic images to the center for further analysis and distribution.
• 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.
• The field element shall collect, process, and send traffic images to the center for further analysis and distribution.
• The field element shall return sensor and CCTV system operational status to the controlling center.

Roadway Signal Controls

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

Roadway Traffic Information Dissemination

• The field element shall include dynamic messages signs for dissemination of traffic and other information to drivers, under center control; the DMS may be either those that display variable text messages, or those that have fixed format display(s) (e.g. vehicle restrictions, or lane open/close).
• The field element shall include dynamic messages signs for dissemination of traffic and other information to drivers, under center control; the DMS may be either those that display variable text messages, or those that have fixed format display(s) (e.g. vehicle restrictions, or lane open/close).
• The field element shall provide operational status for the driver information systems equipment (DMS, HAR, etc.) to the center.

TMC Signal Control

• The center shall remotely control traffic signal controllers.
• The center shall collect traffic signal controller operational status and compare against the control information sent by the center.
• The center shall collect traffic signal controller fault data from the field.
• 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 implement control plans to coordinate signalized intersections based on data from sensors.
• The center shall manage boundaries of the control sections used within the signal system.
• The center shall maintain traffic signal coordination including synchronizing clocks throughout the system.
