Architecture Flow Definitions

barrier system control  (Existing)  Applicable ITS Standards

Information used to configure and control barrier systems that are represented by gates, barriers and other automated or remotely controlled systems used to manage entry to roadways.

data collection and monitoring control  (Existing)  

Information used to configure and control data collection and monitoring systems.

environmental sensor data  (Existing)  Applicable ITS Standards

Current road conditions (e.g., surface temperature, subsurface temperature, moisture, icing, treatment status) and surface weather conditions (e.g., air temperature, wind speed, precipitation, visibility) as measured and reported by fixed and/or mobile environmental sensors. Operational status of the sensors is also included.

environmental sensors control  (Existing)  Applicable ITS Standards

Data used to configure and control environmental sensors.

field device status  (Existing)  

Reports from field equipment (sensors, signals, signs, controllers, etc.) which indicate current operational status.

infrastructure monitoring sensor control  (Future)  

Data used to configure and control infrastructure monitoring sensors.

roadside archive data  (Existing)  

A broad set of data derived from roadside sensors that includes current traffic conditions, environmental conditions, and any other data that can be directly collected by roadside sensors. This data also indicates the status of the sensors and reports of any identified sensor faults.

roadway information system data  (Existing)  Applicable ITS Standards

Information used to initialize, configure, and control roadside systems that provide driver information (e.g., dynamic message signs, highway advisory radio, beacon systems). This flow can provide message content and delivery attributes, local message store maintenance requests, control mode commands, status queries, and all other commands and associated parameters that support remote management of these systems.

roadway information system status  (Existing)  Applicable ITS Standards

Current operating status of dynamic message signs, highway advisory radios, beacon systems, or other configurable field equipment that provides dynamic information to the driver.

signal control plans  (Future)  Applicable ITS Standards

Traffic signal timing parameters including minimum green time and interval durations for basic operation and cycle length, splits, offset, phase sequence, etc. for coordinated systems.

signal system configuration  (Future)  Applicable ITS Standards

Data used to configure traffic signal systems including configuring control sections and mode of operation (time based or traffic responsive).

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 images  (Existing)  Applicable ITS Standards

High fidelity, real-time traffic images suitable for surveillance monitoring by the operator or for use in machine vision applications.

video surveillance control  (Existing)  Applicable ITS Standards

Information used to configure and control video surveillance systems.

work zone warning device control  (Future)  

Data used to configure and control work zone safety monitoring and warning devices.
