Project Functional Requirements (Element - Functional Object):

• City of Lakeland Advanced Traffic Management System - 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.


• City of Lakeland Advanced Traffic Management System - 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.
• 8: The center shall maintain traffic signal coordination including synchronizing clocks throughout the system.


• City of Lakeland 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.


• City of Lakeland 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.
