A multizone RF read/write system for conducting transactions with vehicles traveling at high speeds. A first RF read zone is created, preferably by use of a first gantry that extends over at least one lane and contains at least one RF source that creates a large powerful RF read zone for reading or reading and writing to a transponder on a passing vehicle. Additional RF read zones arranged in tandem with the first RF read zone are created by at least one additional RF source that is located on an additional gantry extending over at least one lane, or located on the first gantry. Accordingly, multiple RF read zones are created to conduct transactions with passing vehicles. In one aspect, the multiple RF read zones can be used to ensure that tolling transactions with a single vehicle are more likely to be completed and have a higher degree of accuracy. In another aspect, the multiple RF read zones each employ a different RF technology so that multiple types of RF toll tags can be read and written.

Multiple RF read zone system

A method and system for synchronization of detection loops in a multilane environment. A plurality of loop sensors are arranged in a plurality of lanes such that loop sensors in adjacent lanes are mutually contiguous. A simultaneous synchronization signal is sent to each of the plurality of loop detector controllers, where each loop detector controller is in communication with a loop sensor. The signal causes a scheduling of sampling periods for each loop sensor, such that the sampling period of each loop sensor does not overlap with that of a contiguous loop in an adjacent lane.

An intelligent vehicle identification system that uses inductive loop technology to profile and classify a vehicle. In a tolling industry application, classification of the vehicle is made prior to the vehicle arriving at a payment point in a toll lane in which the vehicle travels. A predetermined fare associated with the classification is then solicited from an operator of the vehicle without efforts from a toll attendant. In a preferred embodiment, the system also includes an intelligent queue loop that verifies the vehicle at the payment point to prevent misclassification due to a second vehicle, e.g., a motorcycle, that changes from a different lane to the toll lane in question.

Intelligent vehicle identification system

An automatic coin machine having a redundant coin processing system with at least two coin processing mechanisms. The first or the active coin processing mechanism is initially set up to receive coins from a coin diverter which is in communication with a coin collection device. While the active coin processing mechanism is processing the coins received from the coin diverter, the inactive or the second coin processing mechanism can be serviced without affecting operation of the active coin processing mechanism. When the first coin processing mechanism becomes disabled, in need of service, or is otherwise idle, the coin diverter is switched from the first coin processing mechanism to the second coin processing mechanism, thus making the first coin processing mechanism inactive, and at the same time, making the second processing mechanism active. Similarly, the coin diverter can be switched back over to the first coin processing mechanism when the second coin processing mechanism becomes disabled, in need of service, or is otherwise idle.
