Project Functional Requirements (Element - Functional Object):

• Commercial Vehicle - Vehicle Speed Management Assist
• 2: The vehicle shall receive speed warnings from the roadside field equipment.


• FTE Data Collection Field Equipment - Roadway Speed Monitoring and Warning
• 1: The field element shall include sensors to detect vehicle speeds, under traffic or maintenance center control.
• 2: The field element shall include sensors to detect vehicle speeds, under enforcement agency control.
• 3: If the speed detected by vehicle speed sensors is determined to be excessive, the field element shall provide a safe speed advisory to passing drivers via a driver information system (such as portable messages signs, field to vehicle communications to in-vehicle signing systems, etc.).
• 6: The field element shall return operational status for the vehicle speed sensors to the controlling traffic or maintenance center; including measured speeds, warning messages displayed, and violation records.
• 8: The field element shall return fault data for the vehicle speed sensors to the controlling center for repair.


• FTE Data Collection Field Equipment - RSE Speed Warning
• 1: The field element shall provide the reduced speed zone current posted speed limit as established by the controlling center and any roadway configuration changes associated with the reduced speed zone (e.g., lane closures, lane shifts).
• 2: The field element shall provide a warning to a vehicle whose speed has been detected to be over the posted speed limit.


• FTE Data Dissemination Field Equipment - Roadway Speed Monitoring and Warning
• 1: The field element shall include sensors to detect vehicle speeds, under traffic or maintenance center control.
• 3: If the speed detected by vehicle speed sensors is determined to be excessive, the field element shall provide a safe speed advisory to passing drivers via a driver information system (such as portable messages signs, field to vehicle communications to in-vehicle signing systems, etc.).
• 6: The field element shall return operational status for the vehicle speed sensors to the controlling traffic or maintenance center; including measured speeds, warning messages displayed, and violation records.
• 8: The field element shall return fault data for the vehicle speed sensors to the controlling center for repair.


• FTE Data Dissemination Field Equipment - RSE Speed Warning
• 1: The field element shall provide the reduced speed zone current posted speed limit as established by the controlling center and any roadway configuration changes associated with the reduced speed zone (e.g., lane closures, lane shifts).
• 2: The field element shall provide a warning to a vehicle whose speed has been detected to be over the posted speed limit.


• FTE Operations Center (Pompano) - TMC Speed Warning
• 3: The center shall monitor reduced speed zone warning field equipment.
• 4: The center shall control reduced speed zone warning roadside equipment, providing the location and extent of the reduced speed zone, the posted speed limit(s) with information about the applicability of the speed limit(s) (e.g., time of day, day of week, seasonality, relevant vehicle types) and information about associated road configuration changes including lane merges and shifts.


• FTE Operations Center (Turkey Lake) - TMC Speed Warning
• 3: The center shall monitor reduced speed zone warning field equipment.
• 4: The center shall control reduced speed zone warning roadside equipment, providing the location and extent of the reduced speed zone, the posted speed limit(s) with information about the applicability of the speed limit(s) (e.g., time of day, day of week, seasonality, relevant vehicle types) and information about associated road configuration changes including lane merges and shifts.


• Vehicle - Vehicle Speed Management Assist
• 2: The vehicle shall receive speed warnings from the roadside field equipment.

Standards:

• US: NTCIP Warning Device - SNMPv3/TLS
