Architecture Flow Definitions

hri control data   (Future)   No Applicable ITS Standards

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

 

hri request   (Future)   No Applicable ITS Standards

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

 

hri status   (Future)   No Applicable ITS Standards

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

 

pager control_ud   (Future)   No Applicable ITS Standards

Information used to configure and control pager systems.

 

request for right-of-way   (Future)   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   (Future)   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   (Future)   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)   Applicable ITS Standards

Information used to configure and control traffic signal systems.

 

signal control status   (Existing)   Applicable ITS Standards

Status of surface street signal controls.

 

signal control status_ud   (Future)   No Applicable ITS Standards

Status of ITS roadside field equipment, such as school pager systems and red-light-running cameras.

 

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).

 

traffic images   (Future)   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 sensor control   (Existing)   Applicable ITS Standards

Information used to configure and control traffic sensor systems.

 

video surveillance control   (Future)   Applicable ITS Standards

Information used to configure and control video surveillance systems.
