Abstract:

The development and testing of incident detection algorithms was based upon freeway surveillance data obtained from Los Angeles and Minneapolis. In the instance of Los Angeles data, data were in the form of samples of the sensor presence pulses fifteen times per second. For purposes of this study, these data were aggregated in the form of twenty-second averages, by lane, of occupancy and volume. Data obtained from Minneapolis were already aggregated in the form of thirty-second averages of occupancy and volume, usually averaged over all lanes at a sensor station. These aggregated data are available in the form of magnetic tapes. The organization and contents of these tapes are described here. The data include instances of malfunctioning sensors.
