Equipment at the plaza read the transponder electronically and automatically debit the account. In Toronto, Highway 407 adds an important feature that allows cars that are not equipped with transponders to use the facility. Using digital video technology, a computer reads a license plate - matches it against the Motor Vehicle Registry's database, and sends out a monthly bill. Mobility improvements are being supported with project revenues. Feasibility studies are being sponsored in many parts of the country.
Many projects are underway on the international scene in addition to Toronto's innovations.
In Trondheim, daytime electronic variable pricing was introduced in 1991. Inbound traffic has declined by ten percent during toll periods while non-toll period traffic has increased by 9 percent. Weekday bus travel has increased by 7 percent. Revenues are being used for road infrastructure, public transit, and pedestrian and bicycle facilities. Singapore introduced peak pricing in 1975 and the system was updated to a fully automated electronic charging system in the spring of 1998.
