Title:
New Approach to Road Weather: Measuring Slipperiness
Abstract:
In this paper we present results of field testing a new road surface condition sensor based on optical spectroscopy and short distance remote sensing. Since the sensor can provide amount of water, ice and white ice independently of each other, we tested also the feasibility to model directly slipperiness caused by winter weather on road surfaces. In turned out that it is possible to obtain a fair correlation between actually measured and modeled friction values in typical winter weather conditions. The field testing included also a remote infrared surface temperature sensor. Impact of the technology on road weather information systems is discussed.
