Project Functional Requirements (Element - Functional Object):
-
Indian River 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.
-
Indian River 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.
-
Indian River 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
-
Indian River County Field Equipment - Roadway Signal Control
-
1: The field element shall control traffic signals under center control.
-
10: The field element shall receive request for transit vehicle signal priority.
-
15: The field element shall receive requests for emergency vehicle signal preemption.
-
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.
-
8: The field element shall report current transit priority status to the center.
-
Indian River County Field Equipment - Roadway Standard Rail Crossing
-
1: The field element shall collect and process, traffic sensor data in the vicinity of a highway-rail intersection (HRI).
-
Indian River 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).
-
Indian River 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.
-
Indian River County TMC - TMC Roadway Equipment Monitoring
-
1: The center shall collect and store sensor (traffic, pedestrian, multimodal crossing) operational status.
-
2: The center shall collect and store CCTV surveillance system (traffic, pedestrian) operational status.
-
3: The center shall collect and store sensor (traffic, pedestrian, multimodal crossing) fault data and send to the maintenance center for repair.
-
Indian River County 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.
-
12: The center shall adjust signal timing in respond to traffic and environmental parameters at each intersection in real time and adapts so that the traffic network is optimized using available green time to serve the actual traffic demands while minimizing the environmental impact.
-
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.
-
4: The center shall collect traffic signal controller fault data from the field.
-
6: The center shall implement control plans to coordinate signalized intersections based on data from sensors.
-
8: The center shall maintain traffic signal coordination including synchronizing clocks throughout the system.
-
9: The center shall implement control plans to coordinate signalized intersections based on data from sensors and connected vehicles.
-
Indian River County TMC - TMC Standard Rail Crossing Management
-
1: The center shall collect highway-rail intersection (HRI) equipment operational status including both the current state or mode of operation and the current equipment condition.
-
Indian River 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.).
-
4: The center shall collect fault data for the driver information systems equipment (DMS, HAR, etc.) for repair.
