Architecture Flow Definitions

data collection and monitoring control  (Planned)  Applicable ITS Standards

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

hri control data  (Planned)  Applicable ITS Standards

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

hri request  (Planned)  Applicable ITS Standards

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

hri status  (Planned)  Applicable ITS Standards

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

lane management control  (Planned)  Applicable ITS Standards

Information used to configure and control dynamic lane management systems.

lane management information  (Planned)  Applicable ITS Standards

System status including current operational state, violations, and logged information.

probe archive data  (Planned)  Applicable ITS Standards

Probe data that allows calculation of travel times, volumes, and other measures that support transportation planning. Optionally, this flow also includes origin and destination information for vehicles that opt to provide this information.

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  (Planned)  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 information system 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, 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  (Planned)  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.

shoulder management control  (Planned)  Applicable ITS Standards

Information used to configure and control systems that allow use of a shoulder as a lane for vehicular traffic.

shoulder management information  (Planned)  Applicable ITS Standards

System status including current operational state, violations and logged information.

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 from 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 flow  (Planned)  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  (Planned)  Applicable ITS Standards

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

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.

traffic probe data  (Planned)  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, the vehicle may report current position, speed, and heading and snapshots of recent events including route information, starts and stops, speed changes, and other information that can be used to estimate traffic conditions.

traffic sensor control  (Planned)  Applicable ITS Standards

Information used to configure and control traffic sensor systems.

variable speed limit control  (Planned)  Applicable ITS Standards

Information used to configure and control variable speed limit systems including the equipment used to provide current speed limits and other information to drivers and the equipment used to monitor traffic and environmental conditions along the roadway.

variable speed limit status  (Planned)  Applicable ITS Standards

Current operating status of the variable speed limit systems including the state of the equipment.

video surveillance control  (Planned)  Applicable ITS Standards

Information used to configure and control video surveillance systems.
