Interface: Road Weather Information System - Statewide Transportation Management Center
Architecture Flow Definitions
environmental sensor data (Planned) 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.
environmental sensors control (Planned) Applicable ITS Standards
Data used to configure and control environmental sensors.
field device status (Planned) Applicable ITS Standards
Reports from field equipment (sensors, signals, signs, controllers, etc.) which indicate current operational status.
infrastructure monitoring sensor control (Planned) Applicable ITS Standards
Data used to configure and control infrastructure monitoring sensors.
infrastructure monitoring sensor data (Planned) Applicable ITS Standards
Data read from infrastructure-based sensors that monitor the condition or integrity of transportation infrastructure including bridges, tunnels, interchanges, pavement, culverts, signs, transit rail or guideway, and other roadway infrastructure. Includes sensor data and the operational status of the sensors.
roadway treatment system control (Planned) Applicable ITS Standards
Control data for remotely located, automated devices, that affect the roadway surface (e.g. de-icing applications).
roadway treatment system status (Planned) Applicable ITS Standards
Current operational status of automated roadway treatment devices (e.g., anti-icing systems).
traffic flow (Planned) 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 detectors.
traffic images (Planned) Applicable ITS Standards
High fidelity, real-time traffic images suitable for surveillance monitoring by the operator or for use in machine vision applications.
traffic sensor control (Planned) Applicable ITS Standards
Information used to configure and control traffic sensor systems.
video surveillance control (Planned) Applicable ITS Standards
Information used to configure and control video surveillance systems.
