Yes, traction is affected by friction. Friction between a surface and an object can either increase or decrease the traction, depending on the circumstances. More friction typically means better traction, while less friction can lead to reduced traction.

It notifies the driver that the road conditions are creating reduced friction between the tyres and road surface, hence, reduced traction. You'll see it on particularly wet roads, snow/ice covered roads, etc.
