CALINE4模型被广泛用于预测车辆排放对道路附近环境浓度的影响。它要求对车辆排放不同空气污染物的速率进行评估,将车辆流量、速度、类型和车龄等因素考虑在内。在欧洲,计算道路运输排放的计算机程序数据库(COPERT)与当地车辆的详细信息相结合,以获得用于分散建模的特定地点排放因子。评估了CALINE4预测高速公路顺风方向碳氢化合物浓度空间变化的能力,以及COPERT III几种碳氢化合物复合排放因子的准确性。在高速公路的顺风和顺风三个地点发现了七种与交通有关的化合物的浓度。模型和实测的背景校正下风浓度在三个基础上进行了比较:日高峰小时浓度、平均浓度和一组模型评价参数。
The CALINE4 model is widely used to predict the effect of vehicle emissions on ambient concentrations close to roadways. It requires an evaluation of the rate at which different air pollutants are emitted by vehicles, taking into account things such as vehicle flow, velocity, type and age. For Europe the databases of the COmputer Program to calculate Emissions from Road Transport (COPERT) are combined with local vehicle details to obtain site-specific emission factors for dispersion modelling. The ability of CALINE4 to predict the spatial variation of hydrocarbon concentrations downwind of a motorway is assessed, as is the accuracy of COPERT III composite emission factors for several hydrocarbon compounds. The concentrations of seven traffic-associated compounds is found at three locations downwind and upwind of a motorway. Modelled and measured background-corrected downwind concentrations are compared on three bases: daily peak hour concentrations, mean concentrations, and a set of model evaluation parameters.
