ITS Roadway Equipment to Traffic Management Center: environmental sensor data
Flow Description
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.

Solutions
   Solution Description
This solution is used within the U.S.. It combines standards associated with US: NTCIP Environmental Sensors with those for I-F: SNMPv1/TLS. The US: NTCIP Environmental Sensors standards include upper-layer standards required to implement centre-to-field weather and environmental sensor communications. The I-F: SNMPv1/TLS standards include lower-layer standards that define one way to retrofit basic security into SNMPv1 implementations (mainly in the US); however, this only secures the communications link and does not provide end-application security and is not recommended for new deployments.
