Interface: Illinois DOT Road Weather Information Systems - Illinois DOT Maintenance Center
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.
environmental sensors control (Existing) Applicable ITS Standards
Data used to configure and control environmental sensors.
environmental situation data (Planned) Applicable ITS Standards
Aggregated and filtered vehicle environmental data collected from vehicle safety and convenience systems including measured air temperature, exterior light status, wiper status, sun sensor status, rain sensor status, traction control status, anti–lock brake status, and other collected vehicle system status and sensor information. This information flow represents the aggregated and filtered environmental data sets that are provided by the RSE to the back office center. Depending on the RSE configuration and implementation, the data set may also include environmental sensor station data collected by the RSE.
field equipment status (Existing) 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.
