ABSTRACT |
There has been a need to develop a simple measurement system which can continuously evaluate friction coefficients of a snowy and/or icy runway. A currently used standard proper ground-vehicle can measure continuously, but it is very expensive. On the other hand, a simple decelerometer on a common car with limited types of tires is used at airports where heavy snow is uncommon, but it cannot measure continuously. In response to the requirement, a new system that is easily installed on a usual car was developed, enabling the quick and continuous measurement of friction coefficients of snowy and/or icy runways. |
