摘要
通过对交通路口的污染物浓度、车流量和气象要素的调查和监测，研究了污染物的特征及其与交通流量和气象因子的对应关系。结果表明：（１） 车流量随时间变化明显。路口的车流量以出租车占的比例最大。（２） 污染物浓度与车流量有较为密切的关系。ＮＯｘ 、ＣＯ、ＴＳＰ噪声与车流量的相关系数分别为０ ．４８３５５ 、０ ．７９００５１ 、０ ．６４３７９２ 、０ ．５３６８２ ，受温度影响不大。（３） 交通噪声随车流量增大，声级值也相应增大，影响交通噪声的实质因素是机动车的车速和车间距。
By determining and analyzing traffic、the concentration of air pollution and factors of weather, the relationship among air pollution、the factors of weather and traffic was studied. The results show that (1) with the time change, the traffic has obviously change. (2) the concentration of air pollution and traffic have a close relation. Coefficients of traffic with NO\-x、CO、TSP and noises were 0.48335、0.790051、0.647392 and 0.53682,respectively. (3)The noise was increased with increasing of traffic. The main factors that effect traffic noises were the car′s speed and distance.
