Project Functional Requirements (Element - Functional Object):

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.
4: The field element shall return sensor and CCTV system operational status to the controlling center.

1: The field element shall collect, process, and send data to the center to uniquely identify passing vehicles in order to support travel time measurement

4: The field element shall report the current signal control information to the center.
6: The field element shall return traffic signal controller operational status to the center.
7: The field element shall return traffic signal controller fault data to the center.

1: The field element shall include dynamic message 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).
3: The field element shall provide operational status for the driver information systems equipment (DMS, HAR, etc.) to the center.

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

1: The center shall collect time stamped vehicle identities from field equipment.
2: The center shall correlate the time stamped vehicle identities in order to calculate link travel times and derive other traffic measures.

1: The center shall remotely control traffic signal controllers.
3: The center shall collect traffic signal controller operational status and compare against the control information sent by the center.
4: The center shall collect traffic signal controller fault data from the field.
5: 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.
6: The center shall implement control plans to coordinate signalized intersections based on data from sensors.
7: The center shall manage boundaries of the control sections used within the signal system.

1: The center shall collect traffic probe data from vehicles via roadside field equipment.

Osceola County Traffic Operations Center - TMC Traffic Information Dissemination

1: The center shall remotely control dynamic messages signs for dissemination of traffic and other information to drivers.
3: The center shall collect operational status for the driver information systems equipment (DMS, HAR, etc.).
