Architecture Flow Definitions

passive vehicle monitoring control  (Existing)  Applicable ITS Standards

Control commands used to control detection systems that rely on infrastructure–based identification of individual vehicles to measure travel times and other related measures by identifying the same vehicle at different points in the network. Related technologies include Bluetooth readers and license plate recognition systems.

passive vehicle monitoring data  (Existing)  Applicable ITS Standards

Time stamped identifiers that identify the vehicles that have passed through a detection zone.

traffic detector control  (Existing)  Applicable ITS Standards

Information used to configure and control traffic detector systems such as inductive loop detectors and machine vision sensors.

traffic detector data  (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 sensor system.
