First Claim
1. A method of identifying a vehicle in a toll system, the method comprising:
- detecting, using a first sensor that is coupled to a lane transaction system of a toll system, a toll transaction between a first vehicle and the toll system;
generating, by a processor of the lane transaction system, a first toll transaction entry in response to detection by the first sensor of the toll transaction between the first vehicle and the toll system, the first toll transaction entry including a first transaction time stamp generated by a first clock;
detecting, using a second sensor that is separate from the first sensor and that is coupled to an imaging system of the toll system, the toll transaction between the first vehicle and the toll system;
capturing, using an image capture device of the imaging system, a picture deemed to depict the toll transaction between the first vehicle and the toll system in response to detection by the second sensor of the toll transaction between the first vehicle and the toll system;
accessing the first toll transaction entry;
accessing a first picture time stamp associated with the picture, the first picture time stamp being generated by a second clock that is independent from the first clock;
accessing a second toll transaction entry, the second toll transaction entry designating a toll transaction between a second vehicle and the toll system and the second toll transaction entry including a second transaction time stamp generated by the first clock;
accessing a second picture time stamp associated with a picture deemed to depict the toll transaction between the second vehicle and the toll system, the second picture time stamp being generated by the second clock;
calculating, using at least one computer processor, a transaction time difference between the first transaction time stamp and the second transaction time stamp;
calculating a picture time difference between the first picture time stamp and the second picture time stamp; and
enabling the calculated transaction time difference and the calculated picture time difference to be concurrently displayed in a graphical user interface for perception by a user.

Abstract
Identifying a vehicle in a toll system includes accessing a set of toll transaction entries. Each entry in the set designates a toll transaction between a vehicle and the toll system and includes a transaction descriptor and a transaction time stamp. A series of toll transaction pictures is accessed. The series includes a plurality of pictures, each of which is associated with a picture time stamp. A toll transaction entry is identified from the set as a violation transaction entry based on the transaction descriptor. A toll transaction picture is selected from the series. The transaction time stamp of the violation transaction is compared, using a processing device, with the picture time stamp of the selected toll transaction picture. The selected toll transaction picture is identified as a violation picture corresponding to the violation transaction entry based on a result of the comparison.

21. A system for identifying a vehicle in a toll system, the system comprising:
-
a lane transaction system including; a first sensor configured to detect a toll transaction between a first vehicle and the toll system, a first clock, and a lane transaction system processor configured to generate a first toll transaction entry in response to detection by the first sensor of the toll transaction between the first vehicle and the toll system, the first toll transaction entry including a first transaction time stamp generated by the first clock; an imaging system including; a second sensor configured to detect the toll transaction between the first vehicle and the toll system, a second clock that is independent from the first clock, and an image capture device configured to capture a picture deemed to depict the toll transaction between the first vehicle and the toll system in response to detection by the second sensor of the toll transaction between the first vehicle and the toll system; and one or more computer processors configured to; access the first toll transaction entry; access a first picture time stamp associated with the picture, the first picture time stamp being generated by the second clock; access a second toll transaction entry, the second toll transaction entry designating a toll transaction between a second vehicle and the toll system and the second toll transaction entry including a second transaction time stamp generated by the first clock; access a second picture time stamp associated with a picture deemed to depict the toll transaction between the second vehicle and the toll system, the second picture time stamp being generated by the second clock; calculate a transaction time difference between the first transaction time stamp and the second transaction time stamp; calculate a picture time difference between the first picture time stamp and the second picture time stamp; and enable the calculated transaction time difference and the calculated picture time difference to be concurrently displayed in a graphical user interface for perception by a user. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
