Book Description
The current state of knowledge with both studded tire performance and methods of assessing pavement wear is reported. An annotated bibliography is presented of all known research on this subject from the U.S. and European sources, a review and evaluation of the data and results of completed studies and recommendations for future research. The objectives of the study were confined to the following tests: (1) correlation of data on the frictional characteristics of studded tires on ice, packed snow, and on bare pavements, and (2) development of a method, or methods, of quantitative assessment of the difference in wearing and abrasive effects of studded versus unstudded tires on different types of surfaces. A stud-resistance coefficient for operation on ice was derived and all U.S. data are correlated with this parameter and ice temperature.

Book Description
In part I, observations on the traffic stream made under two intensities of artifical illumination and under daylight conditions are studied along with an analysis of the accident rate under day and night conditions over a 5 year period. Part II centers upon the individual driver and his performance in controlling his vehicle under different nighttime illumination levels. The subjects drove an instrumented vehicle equipped with an oscillograph recorder and sensors for velocity, steering, and gas pedal movements. Part III deals with the instrumentation of the vehicle. Part IV pertains to the area of driver apprehension, the effects of illumination change upon visual phenomena and driver responses and the effects upon traffic flow, driver behavior, and accidents.
