Project Functional Requirements (Element - Functional Object):

• Brevard 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.


• Brevard County Field Equipment - Roadway Environmental Monitoring
• 1: The field element shall include surface and sub-surface environmental sensors that measure road surface temperature, moisture, icing, salinity, and other measures.
• 10: The field element shall provide weather and road surface condition data to centers.
• 2: The field element shall include environmental sensors that measure weather conditions including temperature, wind, humidity, precipitation, and visibility.
• 4: The field element's environmental sensors shall be remotely controlled by a traffic management center.


• Brevard 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.
• 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.


• Brevard County Traffic Operations Center - 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.
• 4: The center shall distribute road network conditions data (raw or processed) based on collected and analyzed traffic sensor and surveillance data to other centers.


• Brevard County Traffic Operations Center - TMC Environmental Monitoring
• 1: The traffic center shall remotely control environmental sensors that measure road surface conditions including temperature, moisture, icing, salinity, and other measures.
• 2: The traffic center shall remotely control environmental sensors that measure weather conditions including temperature, wind, humidity, precipitation, and visibility.
• 3: The traffic center shall assimilate current and forecast road conditions and surface weather information using a combination of weather service provider information (such as the National Weather Service and value-added sector specific meteorological services), data from roadway maintenance operations, and environmental data collected from sensors deployed on and about the roadway.
• 4: The traffic center shall receive road condition information from weather service providers.


• Brevard County Traffic Operations Center - TMC Signal Control
• 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.


• Brevard County Traffic Operations Center - TMC Situation Data Management
• 1: The center shall collect traffic probe data from vehicles via roadside field equipment.


• FL511 - TIC Traveler Information Broadcast
• 1: The center shall disseminate traffic and highway condition information to travelers, including incident information, detours and road closures, event information, recommended routes, and current speeds on specific routes.
