Architecture Flow Definitions

speed monitoring control  (Planned)  Applicable ITS Standards

Information used to configure and control automated speed monitoring, speed warning, and speed enforcement systems.

speed monitoring information  (Planned)  Applicable ITS Standards

System status including current operational state and logged information including measured speeds, warning messages displayed, and violation records.

traffic flow  (Existing)  Applicable ITS Standards

Raw and/or processed traffic detector data which allows derivation of traffic flow variables (e.g., speed, volume, and density measures) and associated information (e.g., congestion, potential incidents). This flow includes the traffic data and the operational status of the traffic detectors.

traffic metering control  (Planned)  Applicable ITS Standards

Control commands and operating parameters for ramp meters, interchange meters, mainline meters, and other systems equipment associated with roadway metering operations.

traffic probe data  (Existing)  Applicable ITS Standards

Vehicle data that is used to determine traffic conditions. In a basic implementation, the data could be limited to time stamped unique identifiers that can be used to measure a vehicle’s progress through the network. In more advanced implementations, the vehicle may report current position, speed, and heading and snapshots of recent events including route information, starts and stops, speed changes, and other information that can be used to estimate traffic conditions.

traffic sensor control  (Existing)  Applicable ITS Standards

Information used to configure and control traffic sensor systems.
