Project Functional Requirements (Element - Functional Object):

• City of Sarasota CAV Field Equipment - RSE Situation Monitoring
• 1: The field element shall collect traffic-related data including snapshots of measured speed and heading and events including starts and stops, speed changes, and other vehicle control from vehicles.
• 2: The field element shall provide vehicle situation data to a center for archival.
• 3: The field element shall provide data collection parameters to vehicles.
• 5: The field element shall provide collected vehicle situation and local sensor data to data distribution centers.


• City of Sarasota CAV Field Equipment - RSE Traffic Monitoring
• 1: The field element shall communicate with on-board equipment on passing vehicles to collect current vehicle position, speed, and heading and a record of previous events (e.g., starts and stops, link travel times) that can be used to determine current traffic conditions.
• 2: The field element shall aggregate and forward collected probe information to the center.


• 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 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.
• 5: The field element shall return sensor and CCTV system fault data to the controlling center for repair.

Standards:

• (None-Data) - Secure Internet (ITS)
• US: NTCIP CCTV - SNMPv3/TLS
• US: NTCIP Transportation Sensors - SNMPv3/TLS
• US: NTCIP Video Switches - SNMPv3/TLS

Project Operational Concepts:

Roles and Responsibilities
