City of Sarasota Fiber Optic Cable Expansion

Project Description: This project will upgrade existing twisted pair copper cable to fiber optic cable. The project will also deploy fiber optic cable to areas that currently do not have fiber optic cable neteork. Deployment of this project will expand the existing network which will allow more connectivity and redundancy within the network.

Project Functional Requirements (Element - Functional Object):

City of Sarasota TMC - 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.
7: The center shall remotely control devices to detect traffic.

City of Sarasota TMC - TMC Signal Control

1: The center shall remotely control traffic signal controllers.
4: The center shall collect traffic signal controller fault data from the field.
6: The center shall implement control plans to coordinate signalized intersections based on data from sensors.
8: The center shall maintain traffic signal coordination including synchronizing clocks throughout the system.

City of Sarasota TMC - TMC Traffic Information Dissemination

1: The center shall remotely control dynamic messages signs for dissemination of traffic and other information to drivers.

City of Sarasota Traffic Control 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 Sarasota Traffic Control Equipment - Roadway Signal 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.

City of Sarasota Traffic Control 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).
