Project Functional Requirements (Element - Functional Object):

• Manatee County Field Equipment - 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.


• Manatee County Field Equipment - Roadway Field Management Station Operation
• 1: The field element shall accept configuration information from the center.
• 2: The field element shall pass data provided by the center to local field devices and report data from the field devices back to the center.


• Manatee County Field Equipment - Roadway Signal Control
• 1: The field element shall control traffic signals under center control.
• 3: The field element shall provide the capability to notify the traffic management center of pedestrian calls and pedestrian accommodations.
• 5: The field element shall report current preemption status to the center.
• 8: The field element shall report current transit priority status to the center.


• Manatee County Field Equipment - Roadway Traffic Information Dissemination
• 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.


• Manatee County TMC - TMC Basic Surveillance
• 1: The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements under remote control of the center.
• 6: The center shall maintain a database of surveillance equipment and sensors and associated data (including the roadway on which they are located, the type of data collected, and the ownership of each).


• Manatee County TMC - TMC Roadway Equipment Monitoring
• 1: The center shall collect and store sensor (traffic, pedestrian, multimodal crossing) operational status.


• Manatee County TMC - TMC Signal Control
• 1: The center shall remotely control traffic signal controllers.
• 2: The center shall accept notifications of pedestrian calls.
• 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.


• Manatee County TMC - TMC Traffic Information Dissemination
• 1: The center shall remotely control dynamic messages signs for dissemination of traffic and other information to drivers.
