AIRPOL-4, an air quality prediction model, has been developed by the Virginia Highway and Transportation Research Council for use in complying with the requirements contained in the Federal Aid Program Manual, Vol. 7, Ch. 7, Section 9, November 1, 1973. This report, the second in the AIRPOL series, presents definitive experimental evidence which establishes AIRPOL-4 as an advancement in the field of air quality modeling. Specifically, this report demonstrates that AIRPOL-4 is a more cost-effective, versatile, and accurate model than either of the accepted "standards," CALAIR or HIWAY, and that its level of performance warrants its implementation. The third report in this series provides a detailed introduction to the mechanics and philosophy of using AIRPOL-4.
