Weblateral friction force and tire vertical load as [7, 8]: (1) where is the tire longitudinal friction force, is the tire lateral friction force and is the vertical load. Note that the tire-road friction coefficient only relies on the road surface type, such as ice, snow, and dry asphalt, and its value is between 0 and 1. Webused transverse tining on highways (except for test sections) and instead utilized longitudinal grooving and tining. California today experiences approximately 13% of vehicle miles traveled in the US. The belief at the time was that transverse tining produced higher friction levels, although little data was provided to support this.
