1. A computer-implemented method comprising:

  • generating, using a first clock that is an internal clock of a lane transaction system and in response to detection of respective transponders of transacting vehicles by a sensor of the late transaction system, transaction time stamps of a set of lane transaction entities;

    generating, using a second clock that is an internal clock of an image acquisition system and that is different than the first clock, and in response to separate detection of the transacting vehicles by a sensor that is different from the sensor of the lane transaction system, picture time stamps of a series of lane transaction pictures;

    accessing the set of lane transaction entries, each entry in the set designating a toll transaction between a vehicle and a toll system and including a transaction descriptor and one of the transaction time stamps generated by the first clock;

    accessing the series of lane transaction pictures, the series including a plurality of pictures, each of which is associated one of the picture time stamps generated by the second clock;

    identifying, using a computer processor, a lane transaction entry from the set as a violation transaction entry based on the transaction descriptor;

    selecting a group of lane transaction entries from among the set of lane transaction entries based on the time stamp of the violation transaction entry;

    selecting a group of lane transaction pictures from the series of lane transaction pictures based on the selected group of lane transaction entries and at least one of the time stamps of the series of lane transaction pictures; and

    identifying a lane transaction picture from the group of lane transaction pictures as a violation picture corresponding to the violation transaction entry by associating the group of lane transaction entries with the group of lane transaction pictures.
