Project Functional Requirements (Element - Functional Object):
-
Seminole 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.
-
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.
-
5: The field element shall return sensor and CCTV system fault data to the controlling center for repair.
-
Seminole County Field Equipment - Roadway Passive Monitoring
-
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
-
Seminole County Field Equipment - Roadway Signal Control
-
1: The field element shall control traffic signals under center control.
-
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.
-
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.
-
8: The field element shall report current transit priority status to the center.
-
Seminole County Field Equipment - Roadway Traffic Information Dissemination
-
3: The field element shall provide operational status for the driver information systems equipment (DMS, HAR, etc.) to the center.
-
8: The field element shall include dynamic message signs for dissemination of wrong way entry to drivers.
-
9: The field element shall include driver information systems that communicate directly from a center to the vehicle radio (such as Highway Advisory Radios) for dissemination of wrong way entry to drivers, under center control
-
Seminole 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.
-
2: The center shall monitor, analyze, and distribute traffic images from CCTV systems under remote control of the center.
-
Seminole County TMC - TMC Passive Surveillance
-
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.
-
Seminole County TMC - TMC Roadway Equipment Monitoring
-
2: The center shall collect and store CCTV surveillance system (traffic, pedestrian) operational status.
-
Seminole County TMC - TMC Signal Control
-
1: The center shall remotely control traffic signal controllers.
-
15: The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements at or near signalized intersections.
-
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.
-
Seminole County TMC - 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.).
-
Vehicle - Vehicle Location Determination
-
2: The vehicle shall calculate the location from one or more data sources including positioning systems such as GPS, sensors that track vehicle movement, and maps used to determine the likely vehicle route.
