摘　　要：为了深入细致把握北京市机动车排放特征,本文研究了2017年北京市工作日、非工作日、重污染天、节日和重大活动日五类典型日机动车的交通流特征,分析了不同时段、不同交通方式、不同区域交通流的变化特征。结果表明,北京市工作日机动车的行驶里程最长,五种典型日中,社会小客车的行驶里程占比最高,分时段交通流特征表现呈明显的马鞍型双峰特性,其中货车交通流主要集中在五环到六环之间,以及几个主要交通联络线上,小客车交通流主要集中在四环内。In order to gain a thorough understanding of the vehicle emission characteristics in Beijing,this paper studied the traffic flow characteristics of the five typical days(working day,non-working day,heavy pollution day,festival and big-event day)in Beijing in 2017.The changing characteristics of traffic flow in different time,different traffic modes and different regions were analyzed.The results showed that the vehicle mileage of travel(VKT)on the working day is the highest in the five typical days.In the five types of vehicles,the VKT of the private cars is the highest in all the five typical days.The characteristics of traffic flow in a typical day show obvious saddle-type double peak pattern.The vehicle travelling zones analysis showed that the traffic flow of trucks is mainly concentrated between the Fifth Ring Road,the Sixth Ring Road and several major traffic links,while the traffic flow of private cars is mainly concentrated in the Fourth Ring Road.
