Abstract:
A method, system and computer program product are provided for automating the task of data collection and reduction for highway vehicle detector testing. To evaluate the performance of each detector under test, a set of detection data is accumulated concurrently from each of the detectors. This data consists, at a minimum, of the time of arrival of each vehicle as reported by each detector and a digitized video image of the vehicle at the position-compensated time of detection. The data reduction process allows for applying weighting coefficients to each detection result in the formation of a consensus. These coefficients may be either fixed or adaptively adjusted based upon the learned accuracy of each detector under test. A ground truth reference data set is then generated using the weighted consensus determined from the data generated by all detectors under test. The accuracy of each detector under test is then ascertained by comparison with the ground truth data set, and these comparison results are automatically reported as indications of the accuracy of each detector under test.
