Architecture Flow Definitions

environmental sensor data  (Existing (Partial))  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 en

HRI control data  (Proposed)  Applicable ITS Standards

Data required for HRI information transmitted at railroad grade crossings and within railroad operations.

HRI request  (Proposed)  Applicable ITS Standards

A request for highway-rail intersection status or a specific control request intended to modify HRI operation.

HRI status  (Proposed)  Applicable ITS Standards

Status of the highway-rail intersection equipment including both the current state or mode of operation and the current equipment condition.

intersection blockage notification  (Proposed)  Applicable ITS Standards

Notification that a highway-rail intersection is obstructed and supporting information.

request for right-of-way  (Existing (Partial))  Applicable ITS Standards

Forwarded request from signal prioritization, signal preemption, pedestrian call, multi-modal crossing activation, or other source for right-of-way.

roadway information system data  (Proposed)  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 st

roadway information system status  (Proposed)  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 data  (Existing (Partial))  Applicable ITS Standards

Information used to configure and control traffic signal systems.

signal control status  (Existing (Partial))  Applicable ITS Standards

Status of surface street signal controls including operating condition and current operational state.

traffic flow  (Existing (Partial))  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) for mixed use vehicles.. This flow includes the tra

traffic images  (Existing (Partial))  Applicable ITS Standards

High fidelity, real-time traffic images suitable for surveillance monitoring by the operator or for use in machine vision applications. This flow includes the images and the operational status of the surveillance system.

traffic probe data  (Proposed)  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, th

traffic sensor parameterization  (Existing (Partial))  Applicable ITS Standards

Information used to configure and control traffic sensor systems.

video surveillance control  (Existing (Partial))  Applicable ITS Standards

Information used to configure and control video surveillance systems.
