Abstract

A system for automatic collection of tolls includes 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. 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 in-vehicle processor transmits its identity, its net balance and the toll, which it debits from an account balance. The in-vehicle processor may increment a low balance, in which case it transmits information which is relayed to a central system for billing. Various means for shutting down delinquent in-vehicle components or identifying offender vehicles are described.

Claims

16. An apparatus for locating and identifying a mobile transceiver comprising:

a plurality of stationary transmitters, each of said transmitters transmitting a radio frequency signals carrying identification information, and wherein adjacent ones of said transmitters transmit signals each of which has an antenna signal transmission pattern primary dircetion that is at least substantially parallel to a common direction,

a mobile transceiver having a preassigned identify and including a transmitter, a receiver, and a data processor,

said mobile indetifying a closest one of said plurality of stationary transmitters and thereafter transmitting a signal which indicates the identity of the closest transmitter.

17. An apparatus in accordance with claim 16, wherein said moble transceiver transmits information from which said apparaturs can determine that said mobile transceiver has an account balance below a predefined level.

34. A method for locating and identifying a moble transceiver in accordance with claim 16, wherein said mobile transceiver has an account balance below a prodefined level and further comprising a step of replenishing said balance.

33. A method for locating and identifying a mobile transceiver comprising the steps of:

transmitting a radio frequency signal carrying identification information from cach of a plurality of stationary transmitters, and wherein adjacent ones of said transmitters transmit signals each of which has an antenna signal transmission pattern primary direction that is at least substantially parallel to a common direction; and

identifying a closest one of said plurality of stationary teansmitters and thereafter transmitting a signal which indicates the identity of the closes transmitter with a mobile transceiver, the moblie transceiver having a preassigned inentity and including a transmitter, a receiver, and a processor.
