This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
Used By: This entry is used directly by one other data structure in this standard, a MSG called
MSG_ProbeVehicleData <ASN> <XML>. In addition, this item may be used by data structures in
other ITS standards.
7.107 Data Element: DE_RainSensor
Use: A general sensor of rain intensity which requires further interpretation by the OEM for precise
semantic meaning.
The "Rain Sensor" Probe Data Element is intended to inform Probe Data Users as to how hard it was
raining/snowing in the area the vehicle was traveling at the time the Probe Data snapshot was taken. The
value of the Rain Sensor data element ranges from 0-7, with 0 indicating "No Rain/Snow", 1 indicating
"Light Mist", and 7 indicating "Heavy Downpour". This information could be sent to vehicles approaching
the area to warn drives of raining/snowing conditions ahead or it could provide Traffic Operation Centers
with locations most likely in need of a snowplow.
