| Abstract |
ROADWAY is a finite-difference model which solves a conservation of species equation to predict pollutant concentrations within two hundred meters of a highway. It uses surface layer similarity theory to predict wind and eddy diffusion profiles from temperature at two heights and wind velocity upwind of the highway. A unique feature of the model is its use of vehicle wake theory which was originally developed by Eskridge and Hunt (1979), and was modified by Eskridge and Thompson (1982); Eskridge and Rao (1983, 1985). It is assumed that vehicle wakes affect the wind and turbulence fields in a linear manner with wake intensity a function of vehicle speed, downwind distance, and distance from the wake center. The user has the option of considering NO, NO2, and O3 chemical reactions near the road. Output from the model consists of x-z fields of wind components, eddy diffusion coefficients, and concentration of pollutant. |
