Unique Characteristics
The 407 uses a system of cameras and transponders to toll vehicles automatically. There are no toll booths, hence the name "Express Toll Route" (ETR). It is one of the earliest examples of a highway that exclusively uses open road tolling. Highway 407 is designed as a normal freeway with interchanges connecting directly to surface streets, without the need for toll booth intermediaries (typically via a trumpet interchange) which could otherwise take up significant land. A radio antenna detects when a vehicle with a transponder has entered and exited the highway, calculating the toll rate. For vehicles without a transponder, an automatic number plate recognition system is used. Monthly statements are mailed to users.

Famous quotes containing the word unique:
“At this unique distance from isolation
It becomes still more difficult to find
Words at once true and kind,
Or not untrue and not unkind.”
—Philip Larkin (1922–1986)
