Cold Weather Transit Technology Program. Volume 3. Characteristerics of Ice and Snow at the Interface with Transit Vehicle Surfaces

摘要

This report addresses two aspects of the effects of ice and snow on the transitway interface: (1) traction and rolling resistance, and (2) communication through thin ice layers. The objectives of Volume 3 are to generate data on the traction and rolling resistance for wheels on ice or snow covered roadways under controlled environmental conditions in the laboratory and also to develop useful scaling laws by which the laboratory data can be used to predict the corresponding characteristics for an actual AGT vehicle under severe cold weather conditions.
