| 以上海内环区域高架道路和地面主干道路的交通信息为基础，基于路段的机动车动态排放清单并利用ADMS Urban模型模拟NOx扩散变化。结果表明：道路车流以轻型客车为主，分别占高架路、主干路的77%和60%；1 139条路段工作日平均车流量为95万辆/h，车速为37.5 km/h；NOx小时排放量为127 kg/h～2 019 kg/h，日排放量为25.8 t，重型客车NOx排放量为道路机动车排放NOx的主要来源；模拟NOx质量浓度占环境空气比例为6.6%～73.4%，2：00 NOx质量浓度最低，8：00最高，与交通密度低谷和峰值同步。 |

| Based on the traffic information of the inner ring elevated roads and trunk roads in Shanghai，ADMS Urban model was used to simulate the diffusion characteristics of NOx with the dynamic vehicle emission inventory of road sections. The results showed that light bus accounted for 77% and 60% of the vehicles on the elevated roads and trunk roads respectively. The average daily traffic volume of 1 139 road sections was up to 950 000 vehicles per hour，and the average speed was 37.5 km/h. The hourly NOx emission was 127 kg/h～2 019 kg/h and the daily NOx emission was 25.8 t. Heavy bus was the main source of NOx emissions. The simulated NOx concentration accounted for 6.6%～73.4% of the ambient air. The lowest and the highest concentrations of NOx occurred at 2 o'clock and 8 o'clock in the morning respectively，which agreed with the valley and peak of the traffic density. |
