Project Functional Requirements (Element - Functional Object):
-
Sarasota County Field Equipment - Roadway Basic Surveillance
-
2: The field element shall collect, process, and send traffic images to the center for further analysis and distribution.
-
Sarasota County Field Equipment - Roadway Environmental Monitoring
-
2: The field element shall include environmental sensors that measure weather conditions including temperature, wind, humidity, precipitation, and visibility.
-
4: The field element's environmental sensors shall be remotely controlled by a traffic management center.
-
Sarasota County Field Equipment - Roadway Passive Monitoring
-
1: The field element shall collect, process, and send data to the center to uniquely identify passing vehicles in order to support travel time measurement
-

-
Sarasota County TMC - TMC Environmental Monitoring
-
1: The traffic center shall remotely control environmental sensors that measure road surface conditions including temperature, moisture, icing, salinity, and other measures.
-
2: The traffic center shall remotely control environmental sensors that measure weather conditions including temperature, wind, humidity, precipitation, and visibility.
-
Sarasota County TMC - TMC Passive Surveillance
-
1: The center shall collect time stamped vehicle identities from field equipment.
-
