Project Functional Requirements (Element - Functional Object):
-
FDOT District 4 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.
-
3: The field element shall collect, digitize, and send multimodal crossing and high occupancy vehicle (HOV), and high occupancy toll (HOT) lane sensor data to the center for further analysis and storage.
-
4: The field element shall return sensor and CCTV system operational status to the controlling center.
-
FDOT District 4 Field Equipment - Roadway HOV Control
-
1: The field element shall include sensors to detect high-occupancy vehicle (HOV) lane usage, under center control.
-
10: The field element shall provide traffic flow measures and information regarding vehicle occupancy (i.e., lane usage) in express lanes to the center.
-
8: The field element shall include freeway control devices, such as ramp signals and mainline metering and other systems associated with freeway operations that control use of express lanes, under center control.
-
9: The field element shall include freeway control devices, such as ramp signals and mainline metering and other systems associated with freeway operations that control use of express lanes, under center control.
-
FDOT District 4 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).
-
FDOT District 4 Field Equipment - Roadway Traffic Metering
-
6: The field element shall include lane controls for use on freeways, under center control.
-
7: The field element shall monitor operation of lane control indicators and report to the center any instances in which the indicator response does not match that expected from the indicator control information.
-
8: The field element shall return lane control operational status to the controlling center.
-
9: The field element shall return lane control fault data to the maintenance center for repair.
-
FDOT District 4 FMS - 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.
-
FDOT District 4 FMS - TMC Demand Management Coordination
-
1: The center shall collect and store toll pricing data from payment administration centers, including the price for each road segment to which a toll applies, with the time and date for when it applies.
-
FDOT District 4 FMS - TMC HOV Lane Management
-
9: The center shall remotely control freeway control devices, such as ramp signals and mainline metering and other systems associated with freeway operations that control use of express lanes.
-
FDOT District 4 FMS - TMC Regional Traffic Management
-
1: The center shall exchange traffic information with other traffic management centers including incident information, congestion data, traffic data, signal timing plans, and real-time signal control information.
-
FDOT District 4 FMS - TMC Roadway Equipment Monitoring
-
2: The center shall collect and store CCTV surveillance system (traffic, pedestrian) operational status.
-
FDOT District 4 FMS - TMC Traffic Information Dissemination
-
1: The center shall remotely control dynamic messages signs for dissemination of traffic and other information to drivers.
-
10: The center shall remotely control AM/FM radio rebroadcast equipment to allow vehicles to access radio broadcasts while inside the Port of Miami Tunnel.
-
FDOT District 4 FMS - TMC Traffic Management Decision Support
-
1: The center shall provide center personnel with an integrated regional view of current and forecast road and traffic conditions including traffic incidents, special events, maintenance activities and other events or conditions that impact capacity or demand.
-
4: The recommended actions shall include predefined incident response plans, signal timing plan changes, DMS/HAR messages, lane control strategies and freeway control strategies including ramp metering, interchange metering, and mainline metering.
-
FDOT District 4 FMS - TMC Traffic Metering
-
2: The center shall collect operational status from ramp meters, interchange meters, and mainline meters and compare against the control information sent by the center.
-
4: The center shall implement control strategies, under control of center personnel, on some or all of the freeway network devices (e.g. ramp meters, interchange meters, and mainline meters), based on data from sensors monitoring traffic conditions upstream, downstream, and queue data on the approaches to the meters.
-
7: The center shall remotely control systems to manage use of the freeways, including lane controls.
-
FDOT District 4 FMS - TMC Traffic Network Performance Evaluation
-
5: The center shall exchange traffic information with other traffic management centers, including incidents, congestion data, traffic data, signal timing plans, and real-time signal control information to support overall network performance evaluations.
-
SunPass Customer Service Center - PAC Payment Administration
-
1: The center shall manage toll transactions, including maintaining a log of all transactions and toll pricing structure information.
-
14: This center shall maintain and publish the prices for the electronic payment system.
-
15: The center shall provide the HOT pricing information, including variable pricing based on calendar, time of day, vehicle type and passenger occupancy.
-
2: The center shall dynamically price tolls based on current traffic condition information.
-
6: The center shall manage a local billing database for toll customers.
-
7: The center shall manage the details of toll payment violations based on vehicle information from the ITS roadway payment equipment, registration information from the Department of Motor Vehicles, invalid payment information from a Financial Institution, and previous violation information stored locally, and report such violations to appropriate law enforcement agencies.
