Interface: MDOT TMC - MDOT Traffic Signals
Information Flow Definitions
intersection management application info (Existing)
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)
Infrastructure application status reported by the RSE. This includes current operational state and status of the RSE and a log of operations.
lane management control (Future)
Information used to configure and control dynamic lane management systems.
lane management information (Future)
System status of managed lanes including current operational state, violations, and logged information. This includes lane usage information including both traditional traffic flow measures and special information associated with managed lanes such as measured passenger occupancies. It also includes the operational status of the lane management equipment.
restricted lanes application info (Future)
Restricted lane application configuration data and messaging parameters. This flow defines the location, duration, and operating parameters for lanes that are reserved for the exclusive use of certain types of vehicles (e.g., transit vehicles) or vehicles that meet other qualifications (e.g., number of occupants, low emissions criteria). It may also identify additional vehicles that may be allowed in the lanes as exceptions, though they don't meet specified criteria. It identifies the lane(s), the start and stop locations, start and end times, vehicle restrictions, speed limits and platooning parameters. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.
restricted lanes application status (Future)
Current RSE application status that is monitored by the back office center including the operational state of the RSE, current configuration parameters, and a log of lane use (aggregate profiles of vehicles that checked in to the lane and reported vehicle speeds in the lanes) and RSE communications activity.
right-of-way request notification (Existing)
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 advisory radio data (Planned)
Information used to initialize, configure, and control roadside highway advisory radio. 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 advisory radio status (Planned)
Current operating status of highway advisory radios.
shoulder management control (Future)
Information used to configure and control systems that allow use of a shoulder as a lane for vehicular traffic.
shoulder management information (Future)
System status including current operational state, violations and logged information.
signal control commands (Existing)
Control of traffic signal controllers or field masters including clock synchronization.
signal control device configuration (Existing)
Data used to configure traffic signal control equipment including local controllers and system masters.
signal control plans (Existing)
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)
Operational and status data of traffic signal control equipment including operating condition and current indications.
signal fault data (Existing)
Faults reported by traffic signal control equipment.
signal system configuration (Existing)
Data used to configure traffic signal systems including configuring control sections and mode of operation (time based or traffic responsive).
vehicle signage application info (Future)
In–vehicle signing application configuration data and messaging parameters. This flow provides a list of regulatory, warning, and information messages to be displayed and parameters that support scheduling and prioritizing messages to be issued to passing vehicles. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.
vehicle signage application status (Future)
In–vehicle signing application status reported by the RSE. This includes current operational state and status of the RSE and a log of messages sent to passing vehicles.
