Why Are Traffic Cones Often Seen on Empty Motorways?

[wolram]

Is there some statistic that gives a ball park figure? And doe's anyone knows why they are even there, time after time i see these cones but no activity.

It's possible you've come upon a breeding colony (They have to come from somewhere!). We have a number of nesting areas here in PA and, apparently by law, no one is permitted to disturb them by working within 2 miles. The sole exception is during rush hour.

The formula for required traffic cone density is given as follows:

F = (n * V^2) / IQ

Where F is the cone density (number required per kilometre), n the number of cars passing per hour, V the intended speed limit (in mph), and IQ the intelligence of the average driver for that area. You'll note a particularly high cone density on the M6 in areas around Cannock, Wolverhampton and Coventry because of the denominator of this equation.

Don't worry, Winter's almost here... construction season is almost over.
