1. A temperature measurement device for measuring a temperature of water covering a road surface, comprising:
- a measurement member for measuring water temperature;
a channelling structure, which directly channels water covering the road surface, the channelling structure including a support portion that forms part of;
a measuring chamber, which is open to the road surface, for measuring a temperature of the channelled water, wherein the measurement member includes a temperature measuring head situated in the measuring chamber, anda collecting chamber, which is open to the road surface, the collecting chamber being situated upstream of the measuring chamber when considering a direction in which water flows with respect to the device; and
a roller, which is supported by the support portion, and which causes the measurement member and the channelling structure to be driven over the road surface in such a way that;
the collecting chamber and the measuring chamber form channels that are delimited by the road surface and the support portion, andthe temperature measuring head is situated to face the road surface at a distance from the road surface.

5. A method for measuring a temperature of water covering a road surface, the method comprising:
-
driving a test vehicle over the road surface; sprinkling on the road surface water from aboard the test vehicle, the water being sprinkled at least at first and second different temperatures in succession; and for each of the sprinkled water at the first temperature and the sprinkled water at the second temperature, measuring a temperature of the sprinkled water over which a tire of the test vehicle has driven, wherein the test vehicle includes; a sprinkler for performing the sprinkling, a temperature measurement device for performing the measuring, and the tire, which is positioned downstream from the sprinkler and upstream of the temperature measurement device when considering a direction of travel of the test vehicle, wherein, when the test vehicle is running, the tire drives over the sprinkled water, and the temperature measurement device measures the temperature of the sprinkled water over which the tire has driven, and wherein the temperature measurement device includes; a measurement member for measuring water temperature, a channelling structure, which directly channels water covering the road surface, the channelling structure including a support portion that forms part of; a measuring chamber, which is open to the road surface, for measuring a temperature of the channelled water, wherein the measurement member includes a temperature measuring head situated in the measuring chamber, and a collecting chamber, which is open to the road surface, the collecting chamber being situated upstream of the measuring chamber when considering a direction in which water flow with respect to the device, and a roller, which is supported by the support portion, and which causes the measurement member and the channelling structure to be driven over the road surface in such a way that; the collecting chamber and the measuring chamber form channels that are delimited by the road surface and the support portion, and the temperature measuring head is situated to face the road surface at a distance from the road surface. - View Dependent Claims (6)
