公路交通气态污染物扩散模式中的几何参数计算

Geometry Parameter Computing in Gas Pollutants Diffusion Model of Highway Traffic

通过分析公路交通气态污染物排放源的几何分布 ,推导了直线单元、圆曲线单元、缓和曲线单元 (完整缓和曲线与不完整缓和曲线 )

Analyzing the geometry distribution of gas pollutants diffusion source of highway traffic, this paper deduces the expressions to compute the downwind distance and the crosswind distance from a source element to the forecasting point as the linear source is a line element, a circle element, a spiral element or a compound alignment.
