7.160 Data Element: DE_WiperRate
Use: The current rate at which wiper sweeps are taking place on the subject vehicle. In units of sweeps per
minute. Use a value of 1 for any sweep rate with a period greater than 60 seconds.
ASN.1 Representation:
WiperRate ::= INTEGER (0..255) -- units of sweeps per minute
XML Representation:
<xs:simpleType name="WiperRate" >

In addition, this item may be used by data structures in other ITS standards.
Remarks: [Note: There is debate in the Traffic Info group to change the value system used here to be
"motor on time" rather then sweeps - swipes per unit time. ]
7.161 Data Element: DE_WiperStatusFront
Use: The current status of the wiper system on the front of the subject vehicle.
The "Wiper Status" Probe Data Element is intended to inform Probe Data Users whether or not it was
raining/snowing at the vehicles location at the time the Probe Data snapshot was taken. The element also
provides an indication as to how hard it was raining/snowing by including the "Swipes Per Minute" of the
wiper blades across the windshield. The higher the "Swipes Per Minute", the harder it was
raining/snowing. The element also includes whether the wipers were turned on manually (driver activated)
or automatically (rain sensor activated) to provide additional information as to driving conditions in the
area of the vehicle.
ASN.1 Representation:
WiperStatusFront ::= ENUMERATED {
notEquipped (0),
off (1),
intermittent (2),
low (3),
high (4),
washerInUse (254), -- washing solution being used
