1. A method of detecting a vehicle transacting with a toll system, the method comprising:

  • detecting, using a sensor of a lane transaction system, a first vehicle transacting with a toll system;

    in response to detecting, using the sensor of the lane transaction system, the first vehicle transacting with the toll system, generating a first vehicle lane transaction entry, the first vehicle lane transaction entry designating a toll transaction between the first vehicle and the toll system and being associated with a first vehicle transaction time stamp generated by a clock of the lane transaction system for the toll transaction between the first vehicle and the toll system;

    storing the first vehicle lane transaction entry in a lane transaction entry data store, the lane transaction entry data store being configured to store lane transaction entries that designate toll transactions between vehicles and the toll system and that are associated with transaction time stamps generated by the clock of the lane transaction system for the toll transactions between the vehicles and the toll system;

    detecting, using a sensor of an image acquisition system, the first vehicle transacting with the toll system, the sensor of the image acquisition system being different from the sensor of the lane transaction system;

    in response to detecting, using the sensor of the image acquisition system, the first vehicle transacting with the toll system, generating, using an image capture device of the image acquisition system, a first vehicle picture of the first vehicle transacting with the toll system and generating, using a clock of the image acquisition system, a first vehicle picture time stamp for the first vehicle picture, the clock of the image acquisition system being different from the clock of the lane transaction system;

    storing the first vehicle picture in a vehicle image data store, the vehicle image data store being configured to store toll transaction pictures that are associated with picture time stamps generated by the clock of the image acquisition system; and

    identifying the first vehicle picture and the first vehicle lane transaction entry as corresponding to a same toll transaction by matching the first vehicle picture with the first vehicle lane transaction entry.
