Interface: Local City Traffic Signals - Local City TMC
Information Flow Definitions
intersection management application info (Future)
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 (Future)
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)
Data required for HRI information transmitted at railroad grade crossings and within railroad operations.
rail crossing status (Existing)
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 (Future)
Notice that a request has occurred for signal prioritization, signal preemption, pedestrian call, multi–modal crossing activation, or other source for right–of–way.
signal control commands (Future)
Control of traffic signal controllers or field masters including clock synchronization.
signal control device configuration (Future)
Data used to configure traffic signal control equipment including local controllers and system masters.
signal control plans (Future)
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 (Future)
Operational and status data of traffic signal control equipment including operating condition and current indications.
signal fault data (Future)
Faults reported by traffic signal control equipment.
signal system configuration (Future)
Data used to configure traffic signal systems including configuring control sections and mode of operation (time based or traffic responsive).
