Interface: Huron Speed Warning System - Local Jurisdiction Public Works
Architecture Flow Definitions
barrier system control (Planned) Applicable ITS Standards
Information used to configure and control barrier systems that are represented by gates, barriers and other automated or remotely controlled systems used to manage entry to roadways.
barrier system status (Planned) Applicable ITS Standards
Current operating status of barrier systems. Barrier systems represent gates, barriers and other automated or remotely controlled systems used to manage entry to roadways. Status of the systems includes operating condition and current operational state.
environmental sensor data (Existing) 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 (Existing) Applicable ITS Standards
Data used to configure and control environmental sensors.
field device status (Existing) Applicable ITS Standards
Reports from field equipment (sensors, signals, signs, controllers, etc.) which indicate current operational status.
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.
right-of-way request notification (Existing) 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 information system data (Existing) 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 (Existing) 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.
signal control commands (Existing) Applicable ITS Standards
Control of traffic signal controllers or field masters including clock synchronization.
signal control device configuration (Existing) Applicable ITS Standards
Data used to configure traffic signal control equipment including local controllers and system masters.
signal control plans (Existing) 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 (Existing) Applicable ITS Standards
Operational and status data of traffic signal control equipment including operating condition and current indications.
signal fault data (Existing) Applicable ITS Standards
Faults from traffic signal control equipment.
signal system configuration (Existing) Applicable ITS Standards
Data used to configure traffic signal systems including configuring control sections and mode of operation (time based or traffic responsive).
speed monitoring control (Existing) Applicable ITS Standards
Information used to configure and control automated speed monitoring, speed warning, and speed enforcement systems.
speed monitoring information (Existing) Applicable ITS Standards
System status including current operational state and logged information including measured speeds, warning messages displayed, and violation records.
traffic flow (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 detectors.
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.
traffic metering control (Existing) 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 (Existing) 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 sensor control (Existing) Applicable ITS Standards
Information used to configure and control traffic sensor systems.
video surveillance control (Existing) Applicable ITS Standards
Information used to configure and control video surveillance systems.
