Interface: NDDOT Traffic Signals - NDDOT TOC
Information Flow Definitions
barrier system status (Existing) Selected Comm Solution
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.
flood sensor control (Existing)
intersection management application info (Existing) Selected Comm Solution
Intersection and device configuration data, including intersection geometry, and warning parameters and thresholds. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.
intersection management application status (Existing) Selected Comm Solution
Infrastructure application status reported by the RSE. This includes current operational state and status of the RSE and a log of operations.
rail crossing control data (Existing) Selected Comm Solution
Data required for HRI information transmitted at railroad grade crossings and within railroad operations.
rail crossing request (Existing) Selected Comm Solution
A request for highway–rail intersection status or a specific control request intended to modify HRI operation.
rail crossing status (Existing) Selected Comm Solution
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) Selected Comm Solution
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 (Existing) Selected Comm Solution
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 devices.
roadway dynamic signage status (Existing) Selected Comm Solution
Current operating status of dynamic message signs.
signal control commands (Existing) Selected Comm Solution
Control of traffic signal controllers or field masters including clock synchronization.
signal control device configuration (Existing) Selected Comm Solution
Data used to configure traffic signal control equipment including local controllers and system masters.
signal control plans (Existing) Selected Comm Solution
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) Selected Comm Solution
Operational and status data of traffic signal control equipment including operating condition and current indications.
signal fault data (Existing) Selected Comm Solution
Faults reported by traffic signal control equipment.
speed monitoring control (Existing) Selected Comm Solution
Information used to configure and control automated speed monitoring, speed warning, and speed enforcement systems.
speed monitoring information (Existing) Selected Comm Solution
System status including current operational state and logged information including measured speeds, warning messages displayed, and violation records.
traffic image meta data (Existing) Selected Comm Solution
Meta data that describes traffic images. Traffic images (video) are in another flow.
