Abstract
A monitoring system alarms drivers of potentially dangerous road surface conditions such as water buildup or icing before it is perceptible to them reducing the possibility of an accident. The road surface friction (RSF) measurement analysis and alarm system monitors RFS utilizing either of two techniques: an extension of the vehicle's automatic braking system including those commonly referred to as the antilock braking system (ABS) to measure tire/wheel slip at constant velocity or accelerating; or an apparatus independent of ABS which rolls against the road surface to determine RSF condition. Both techniques analyze data and alarm or advise the driver of a potentially dangerous RSF condition.
