Abstract:
A system and method to facilitate drive-through ordering in which two or more options are presented to a customer and an in-vehicle transponder includes an input device to receive customer selection of one of the two or more options. The user selection received via the input device is relayed to the vendor through RF communications between the transponder and a reader.
Abstract:
An electronic toll collection system with dynamically adjusted timing for operation of one or more subsystems. The timing is dynamically adjusted based upon the prevailing traffic speed for the roadway. The roadway traffic speed is determined based upon direct measurements of traffic speed by external equipment or based upon a variable correlated with traffic speed. The variable may include the average number of handshakes per transponder over an estimation period. The subsystem may include a vehicle position determination system, an enforcement system, a loop detection system, or other such subsystems.
