Project Functional Requirements (Element - Functional Object):

• FDOT District 7 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.


• FDOT District 7 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 7 Tampa Bay SunGuide Center - Emergency Response Management
• 6: The center shall allocate the appropriate emergency services, resources, and vehicle (s) to respond to incidents, and shall provide the capability to override the current allocation to suit the special needs of a current incident.


• FDOT District 7 Wrong Way Detection 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.


• FDOT District 7 Wrong Way Detection System - TMC Incident Detection
• 2: The center shall collect and store traffic flow and image data from the field equipment to detect and verify incidents.


• FDOT District 7 Wrong Way Detection System - TMC Traffic Information Dissemination
• 1: The center shall remotely control dynamic messages signs for dissemination of traffic and other information to drivers.
• 15: The center shall coordinate information dissemination with other traffic management centers.

Standards:

• (None-Data) - Secure Internet (ITS)
