Interface: RTC FAST TMC - NDOT District 1 ATM Field Equipment
Architecture Flow Definitions
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.
field equipment status (Planned) Applicable ITS Standards
Reports from field equipment (sensors, signals, signs, controllers, etc.) which indicate current operational status.
mixed use safety warning control (Planned) Applicable ITS Standards
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.
rail crossing blockage notification (Existing) Applicable ITS Standards
Notification that a highway–rail intersection is obstructed and supporting 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.
roadway dynamic signage data (Planned) Applicable ITS Standards
Information used to initialize, configure, and control dynamic message signs. 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.
roadway warning system control (Planned) Applicable ITS Standards
Information used to configure and control roadway warning systems.
roadway warning system status (Planned) Applicable ITS Standards
Current operating status of roadway warning systems.
traffic detector control (Planned) Applicable ITS Standards
Information used to configure and control traffic detector systems such as inductive loop detectors and machine vision sensors.
traffic detector data (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 sensor system.
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. 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.
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.
work zone warning device control (Planned) Applicable ITS Standards
Data used to configure and control work zone safety monitoring and warning devices.
work zone warning status (Planned) Applicable ITS Standards
Status of a work zone safety monitoring and warning devices. This flow documents system activations and includes additional supporting information (e.g., an image) that allows verification of the alarm.
