In October 1995, the University of California, Davis (UCD), in conjunction with the California Department of Transportation (CALTRANS) Environmental Program, initiated a two-year investigation to determine if CALINE4 was adequately predicting CO concentrations during 'worst case' meteorological conditions. To explore the role that exhaust buoyancy plays in roadway pollutant dispersion, a series of experiments were conducted on I-80 during winter pre-dawn commute hours. Results of the dispersion studies were inconclusive. However, a compare-contrast study of field measurements versus CALINE4 predictions verified that CALINE4 adequately predicts both the magnitude and qualitative shape of non-worst case pollutions scenarios.
