Interface: City of Ridgeland TMC - City of Ridgeland Work Zone Intrusion Detector
Information Flow Definitions
data collection and monitoring control (Existing)
Information used to configure and control data collection and monitoring systems.
passive vehicle monitoring control (Existing)
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 (Existing)
Time stamped identifiers that identify the vehicles that have passed through a detection zone.
rail crossing control data (Planned)
Data required for HRI information transmitted at railroad grade crossings and within railroad operations.
rail crossing request (Planned)
A request for highway–rail intersection status or a specific control request intended to modify HRI operation.
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 (Planned)
Notice that a request has occurred for signal prioritization, signal preemption, pedestrian call, multi–modal crossing activation, or other source for right–of–way.
roadside archive data (Planned)
A broad set of data derived from roadside sensors that includes current traffic conditions, environmental conditions, and any other data that can be directly collected by roadside sensors. This data also indicates the status of the sensors and reports of any identified sensor faults.
roadway advisory radio data (Existing)
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 (Existing)
Current operating status of highway advisory radios.
roadway dynamic signage data (Existing)
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)
Current operating status of dynamic message signs.
signal control commands (Existing)
Control of traffic signal controllers or field masters including clock synchronization.
signal control device configuration (Planned)
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 (Planned)
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).
traffic detector control (Future)
Information used to configure and control traffic detector systems such as inductive loop detectors and machine vision sensors.
traffic image meta data (Existing)
Meta data that describes traffic images. Traffic images (video) are in another flow.
traffic images (Existing)
High fidelity, real–time traffic images suitable for surveillance monitoring by the operator or for use in machine vision applications. This flow includes the images. Meta data that describes the images is contained in another flow.
video surveillance control (Existing)
Information used to configure and control video surveillance systems.
work zone warning status (Future)
Status of a work zone safety monitoring and warning devices. This flow documents system activations and includes additional supporting information (e.g., an image) that allows verification of the alarm.
