Tolls are annoying, but high-speed toll collecting is an interesting technology mix

Laser scanners, embedded induction loops, high-speed cameras - it takes a lot for a system to accurately (most of the time, anyway) assess cars for highway tolls at highway speeds. For example: how do you tell the difference between a truck hauling a trailer and a truck being tailgated by a car?

My story in The Telegraph today takes a look at some of that technology - here it is.

It takes no stance on whether collecting tolls is a good thing or a bad thing (for which a couple of readers have been critical).
