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:
“I feel free as a bird. I’m in a unique position because I’m the boss. I buy what I like. I initiate things. I can experiment with all kinds of things I think the kids might be interested in. Nobody interferes. For me, it’s no chore to go to work. Most people never get to do this at any time in their lives.”
—Sarah Houghton, U.S. librarian. As quoted in Working, book 9, by Studs Terkel (1973)
