Interface: ODOT District 8 Signal Operations - ODOT District 8 Field Equipment
Information Flow Definitions
passive vehicle monitoring control (Planned) Selected Comm Solution
Control commands used to control detection systems that rely on infrastructure–based identification of individual vehicles to measure travel times and other related measures by identifying the same vehicle at different points in the network. Related technologies include Bluetooth readers and license plate recognition systems.
passive vehicle monitoring data (Planned) Selected Comm Solution
Time stamped identifiers that identify the vehicles that have passed through a detection zone.
rail crossing control data (Planned) Selected Comm Solution
Data required for HRI information transmitted at railroad grade crossings and within railroad operations.
rail crossing request (Planned) Selected Comm Solution
A request for highway–rail intersection status or a specific control request intended to modify HRI operation.
rail crossing status (Planned) Selected Comm Solution
Status of the highway–rail intersection equipment including both the current state or mode of operation and the current equipment condition.
signal control commands (Planned) Selected Comm Solution
Control of traffic signal controllers or field masters including clock synchronization.
signal control device configuration (Planned) Selected Comm Solution
Data used to configure traffic signal control equipment including local controllers and system masters.
signal control plans (Planned) 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 (Planned) Selected Comm Solution
Operational and status data of traffic signal control equipment including operating condition and current indications.
signal fault data (Planned) Selected Comm Solution
Faults reported by traffic signal control equipment.
signal system configuration (Planned) Selected Comm Solution
Data used to configure traffic signal systems including configuring control sections and mode of operation (time based or traffic responsive).
speed monitoring control (Planned) Selected Comm Solution
Information used to configure and control automated speed monitoring, speed warning, and speed enforcement systems.
speed monitoring information (Planned) Selected Comm Solution
System status including current operational state and logged information including measured speeds, warning messages displayed, and violation records.
traffic detector control (Planned) Selected Comm Solution
Information used to configure and control traffic detector systems such as inductive loop detectors and machine vision sensors.
traffic detector data (Planned) Selected Comm Solution
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
video surveillance control (Planned) Selected Comm Solution
Information used to configure and control video surveillance systems.
