Interface: RTC FAST TMC - Boulder 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.
lane management control (Planned) Applicable ITS Standards
Information used to configure and control dynamic lane management systems.
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 (Planned) Applicable ITS Standards
Notification that a highway–rail intersection is obstructed and supporting information.
rail crossing control data (Planned) Applicable ITS Standards
Data required for HRI information transmitted at railroad grade crossings and within railroad operations.
rail crossing request (Planned) Applicable ITS Standards
A request for highway–rail intersection status or a specific control request intended to modify HRI operation.
rail crossing 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.
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.
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 (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.
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.
