Abstract

A system for automatic collection of tolls includes a toll facility, an in-vehicle toll processor having memory for storing a toll-money-available quantity purchased by the user, and a toll-facility-identification site that transmits a toll-facility-identifier signal indicating the identity of the upcoming toll facility and the toll to be collected. As the vehicle approaches the identification site, the in-vehicle processor receives the identifier signal and calculates the toll to be debited. When the vehicle passes through the toll facility, the facility transmits a toll-collect signal instructing the in-vehicle toll processor to debit the calculated toll from memory. The in-vehicle processor debits the calculated amount and transmits an acknowledgement signal to the toll facility.
