Project Functional Requirements (Element - Functional Object):

• City of Tallahassee 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).
• 4: The field element shall provide fault data for the driver information systems equipment (DMS, HAR, etc.) to the center for repair.


• City of Tallahassee Field Equipment - Roadway Work Zone Safety
• 1: The field element shall include work zone intrusion detection devices that detect when a vehicle has intruded upon the boundary of a work zone, under center control.
• 3: The field element shall include work zone intrusion alerting devices that alert crew workers of a work zone emergency or safety issue such as the intrusion of a vehicle into the work zone area or movement of field crew into the travel lanes or vehicles approaching at an unsafe speed.
• 6: The field element shall provide operational status for the work zone intrusion detection devices to the maintenance center.
• 7: The field element shall provide fault data for the work zone intrusion detection devices to the maintenance center for repair.
• 8: The field element shall provide operational status for the work zone intrusion alerting devices to the maintenance center.
• 9: The field element shall provide fault data for the work zone intrusion alerting devices to the maintenance center for repair.


• City of Tallahassee Field Equipment - Roadway Work Zone Traffic Control
• 1: The field element shall collect, process, and send work zone images to the center for further analysis and distribution, under center control.
• 2: Under traffic and maintenance center control, the field element shall include driver information systems (such as dynamic messages signs and highway advisory radios) that advise drivers of activity around the work zone through which they are currently passing.
• 3: Under the control of field personnel within maintenance vehicles, the field element shall include driver information systems (such as dynamic messages signs and highway advisory radios) that advise drivers of activity around a work zone through which they are currently passing.
• 5: The field element shall provide operational status for the surveillance (e.g. CCTV), driver information systems, and gates/barriers in work zones to the maintenance center.
• 6: The field element shall provide fault data for the surveillance (e.g. CCTV), driver information systems, and gates/barriers in work zones to the maintenance center for repair.


• City of Tallahassee Field Equipment - RSE Traveler Information Communications
• 1: The field element shall distribute traveler information including traffic and road conditions or upcoming work zones to passing vehicles using short range communications, under center control.
• 2: The field element shall distribute advisory information, such as evacuation information, wide-area alerts, incident information, work zone intrusion information, recommended speed limit and other special information to passing vehicles using short range communications, under center control.
• 4: The field element shall return system operational status to the controlling center.
• 5: The field element shall return system fault data to the maintenance center for repair.


• City of Tallahassee STMC - TMC Work Zone Traffic Management
• 1: The center shall receive work zone images from a maintenance center.
• 2: The center shall analyze work zone images for indications of a possible incident.
• 4: The center shall collect operational status for the driver information systems equipment in work zones.
• 5: The center shall collect fault data for the driver information systems equipment in work zones for repair.


• County and City Roadway Maintenance and Construction Systems - MCM Work Zone Management
• 2: The center shall control the collection of work zone status information including video images from cameras located in or near the work zone.
• 4: The center shall control traffic in work zones by providing remote control of dynamic message signs, highway advisory radio systems, gates, and barriers located in or near the work zone.


• FDOT District 3 Construction and Maintenance System - MCM Work Zone Management
• 2: The center shall control the collection of work zone status information including video images from cameras located in or near the work zone.
• 4: The center shall control traffic in work zones by providing remote control of dynamic message signs, highway advisory radio systems, gates, and barriers located in or near the work zone.
