Interface: NYSTA Statewide Operations Center (TSOC) - NYSTA ITS Field Equipment

Information Flow Definitions

field equipment status (Existing) Selected Comm Solution

Reports from field equipment (sensors, signals, signs, controllers, etc.) which indicate current operational status.

lane management control (Existing) Selected Comm Solution

Information used to configure and control dynamic lane management systems.

lane management information (Existing) Selected Comm Solution

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.

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.

shoulder management control (Existing) Selected Comm Solution

Information used to configure and control systems that allow use of a shoulder as a lane for vehicular traffic.

shoulder management information (Existing) Selected Comm Solution

System status including current operational state, violations and logged information.

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.

signal system configuration (Existing) Selected Comm Solution

Data used to configure traffic signal systems including configuring control sections and mode of operation (time based or traffic responsive).

traffic detector control (Existing) Selected Comm Solution

Information used to configure and control traffic detector systems such as inductive loop detectors and machine vision sensors.

traffic detector data (Existing) 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

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.

traffic metering control (Existing) Selected Comm Solution

Control commands and operating parameters for ramp meters, interchange meters, mainline meters, and other systems equipment associated with roadway metering operations.

traffic metering status (Existing) Selected Comm Solution

Current operational status and operating parameters for ramp meters, interchange meters, mainline meters and other control equipment associated with roadway metering operations.

variable speed limit control (Existing) Selected Comm Solution

Information used to configure and control variable speed limit systems including the equipment used to provide current speed limits and other information to drivers.

variable speed limit status (Existing) Selected Comm Solution

Current operating status of the variable speed limit systems including the state of the equipment.

video surveillance control (Existing) Selected Comm Solution

Information used to configure and control video surveillance systems.
