Project Functional Requirements (Element - Functional Object):

City of Sarasota TMC - TMC Signal Control

1: The center shall remotely control traffic signal controllers.
10: The center shall adjust signal timing in respond to a signal prioritization, signal preemption, pedestrian call, multi-modal crossing activation, or other requests for right-of-way.
15: The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements at or near signalized intersections.
2: The center shall accept notifications of pedestrian calls.
3: The center shall collect traffic signal controller operational status and compare against the control information sent by the center.
9: The center shall implement control plans to coordinate signalized intersections based on data from sensors and connected vehicles.

City of Sarasota Traffic Control 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.
2: The field element shall collect, process, and send traffic images to the center for further analysis and distribution.
5: The field element shall return sensor and CCTV system fault data to the controlling center for repair.
6: The field element shall collect, process, and send traffic images to the center for further wrong way vehicle entries analysis and detection.

City of Sarasota Traffic Control 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.

City of Sarasota Traffic Control Equipment - Roadway Mixed Use Crossing Safety

1: The field element shall collect images or sensor data for pedestrians or bicyclists and respond to pedestrian or bicyclist crossing requests via display, audio signal, or other manner.
2: The field element shall respond to pedestrian or bicyclist crossing requests via display, audio signal, or other manner.
3: The field element shall inform pedestrians and bicyclists of the status of the intersection including the amount of time left for crossing the intersection.

City of Sarasota Traffic Control Equipment - Roadway Signal Control

1: The field element shall control traffic signals under center control.
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.
6: The field element shall return traffic signal controller operational status to the center.
