摘　　要：为了深入细致地把握北京市机动车排放特征,本文基于不同的交通流数据采集和获取方式,建立了北京市主要路网上不同类型车辆交通流预测算法,并通过与交通调查数据进行对比验证,开发了北京市2017年动态交通流模型,并对北京市路网上不同类型车辆典型交通流变化趋势进行了初步模拟。研究结果表明,北京市2017年动态交通流模型可以较好地模拟和预测北京市不同类型机动车交通流变化趋势,可以为进一步研究开发北京市2017年动态精细化交通排放清单打下基础。In order to gain a thorough understanding of the vehicle emission characteristics in Beijing, the dynamic traffic flow model of Beijing 2017 was developed based on the algorithms for forecasting traffic flow of different types of vehicles and the data collected by the different methods on the main road network, while the validation and comparison was conducted.The typical traffic flow trend of different types of vehicles on the main road network was simulated.The results show that the model of dynamic traffic flow developed could simulate and forecast the trend of different types of motor vehicle traffic flow in Beijing well, which lay a foundation for further research of the dynamic vehicle emission in Beijing in 2017.
