Architecture Flow Definitions

data collection and monitoring control (Existing) Applicable ITS Standards

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

environmental sensor data (Planned) 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 (Planned) Applicable ITS Standards

Data used to configure and control environmental sensors.

local situation data (Existing) Applicable ITS Standards

This general flow represents the traffic, environmental, and emissions situation data that is collected from connected vehicles by an RSE, aggregated, filtered, and provided to a back-office center. It also includes data collected from ITS roadway equipment that provides current intersection and road network status for the area proximate to the RSE.

right-of-way request notification (Planned) Applicable ITS Standards

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

roadside archive data (Existing) Applicable ITS Standards

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 dynamic signage data (Planned) Applicable ITS Standards

Information used to initialize, configure, and control roadside systems that provide driver information (e.g., dynamic message signs, 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 dynamic signage status (Planned) Applicable ITS Standards

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

signal control commands (Planned) Applicable ITS Standards

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

signal control device configuration (Planned) Applicable ITS Standards

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

signal control plans (Planned) 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 control status (Planned) Applicable ITS Standards

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

signal fault data (Planned) Applicable ITS Standards

Faults reported by traffic signal control equipment.

signal system configuration (Planned) Applicable ITS Standards

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

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.

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. This flow includes the images and meta data that describes the images.

traffic metering control (Planned) Applicable ITS Standards

Control commands and operating parameters for ramp meters, interchange meters, mainline meters, and other systems equipment associated with roadway metering operations.

traffic metering status (Planned) Applicable ITS Standards

Current operational status and operating parameters for ramp meters, interchange meters, mainline meters and other control equipment associated with roadway metering operations.

video surveillance control (Existing) Applicable ITS Standards

Information used to configure and control video surveillance systems.
