Information Flow Definitions

environmental sensor data  (Planned)  Selected Comm Solution

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  (Planned)  Selected Comm Solution

Data used to configure and control environmental sensors.

mixed use safety warning control  (Planned)  Selected Comm Solution

Configuration and control of equipment that monitors and manages mixed use crossings and provides visual displays and warnings to drivers when non–motorized users are occupying a cross walk or other mixed use path crossing.

mixed use safety warning status  (Planned)  Selected Comm Solution

Current operational status and state of pedestrian crossings and other mixed use path crossing warning systems.

passive vehicle monitoring control  (Planned)  Selected Comm Solution

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  (Planned)  Selected Comm Solution

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

rail crossing control data  (Planned)  Selected Comm Solution

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

rail crossing request  (Planned)  Selected Comm Solution

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

rail crossing status  (Planned)  Selected Comm Solution

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

right-of-way request notification  (Existing)  Selected Comm Solution

Notice that a request has occurred for signal prioritization, signal preemption, pedestrian call, multi–modal crossing activation, or other source for right–of–way.

roadway advisory radio data  (Planned)  Selected Comm Solution

Information used to initialize, configure, and control roadside highway advisory radio. 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 advisory radio status  (Planned)  Selected Comm Solution

Current operating status of highway advisory radios.

roadway warning system control  (Planned)  Selected Comm Solution

Information used to configure and control roadway warning systems.

roadway warning system status  (Planned)  Selected Comm Solution

Current operating status of roadway warning systems.

signal control commands  (Existing)  Selected Comm Solution

Control of traffic signal controllers or field masters including clock synchronization.

signal control device configuration  (Existing)  Selected Comm Solution

Data used to configure traffic signal control equipment including local controllers and system masters.

signal control plans  (Existing)  Selected Comm Solution

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 control status  (Existing)  Selected Comm Solution

Operational and status data of traffic signal control equipment including operating condition and current indications.

signal fault data  (Existing)  Selected Comm Solution

Faults reported by traffic signal control equipment.

signal system configuration  (Existing)  Selected Comm Solution

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

traffic detector control  (Existing)  Selected Comm Solution

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

traffic detector data  (Existing)  Selected Comm Solution

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 image meta data  (Planned)  Selected Comm Solution

Meta data that describes traffic images. Traffic images (video) are in another flow.

traffic images  (Existing)  

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. Meta data that describes the images is contained in another flow.

video surveillance control  (Existing)  Selected Comm Solution

Information used to configure and control video surveillance systems.
