WCDPWT Traffic Management to WCDPWT ITS Field Equipment Interface Diagram

Architecture Flow Definitions

environmental sensor data (Existing) Applicable ITS Standards

Current road conditions (e.g., surface temperature, subsurface temperature, moisture, icing, treatment status) and surface weather conditions (e.g., air temperature, wind speed, precipitation, visibility) as measured and reported by fixed and/or mobile environmental sensors. Operational status of the sensors is also included.

right-of-way request notification (Existing) Applicable ITS Standards

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 dynamic signage data (Existing) Applicable ITS Standards

Information used to initialize, configure, and control roadside systems that provide driver information (e.g., dynamic message signs, 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 dynamic signage status (Existing) Applicable ITS Standards

Current operating status of dynamic message signs, highway advisory radios, or other configurable field equipment that provides dynamic information to the driver.

roadway warning system control (Existing) Applicable ITS Standards

Information used to configure and control roadway warning systems.

roadway warning system status (Existing) Applicable ITS Standards

Current operating status of roadway warning systems.

signal control commands (Existing) Applicable ITS Standards

Control of traffic signal controllers or field masters including clock synchronization.

signal control device configuration (Existing) Applicable ITS Standards

Data used to configure traffic signal control equipment including local controllers and system masters.

signal control plans (Existing) Applicable ITS Standards

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) Applicable ITS Standards

Operational and status data of traffic signal control equipment including operating condition and current indications.

signal fault data (Existing) Applicable ITS Standards

Faults reported by traffic signal control equipment.

signal system configuration (Existing) Applicable ITS Standards

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

traffic detector control (Existing) Applicable ITS Standards

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

traffic detector data (Existing) Applicable ITS Standards

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 sensor system.

traffic situation data (Existing) Applicable ITS Standards

Current, aggregate traffic data collected from connected vehicles that can be used to supplement or replace information collected by roadside traffic detectors. It includes raw and/or processed reported vehicle speeds, counts, and other derived measures. Raw and/or filtered vehicle control events may also be included to support incident detection.
