The invention provides an hour traffic volume measuring and calculating method for a road section of a high-resolution motor vehicle dynamic emission list, and is used for solving the problem of lackof hour traffic volume measurement and calculation for the road section of the high-temporal-spatial-resolution motor vehicle dynamic emission list in the prior art. The hour traffic volume measuringand calculating method comprises the steps: sequentially constructing FCD speed and traffic volume space-time matching data, a traffic flow mode database and a basic graph model database based on FCDspeed data and traffic flow state classification to form a measurement and calculation model database, then calling a corresponding measurement and calculation model from the measurement and calculation model database according to the current road section limiting condition, and dynamically measuring and calculating the hour traffic volume of the road section. According to the method, the dynamiccalculation of the hour traffic volume of the road section without monitoring the traffic volume in the road network is realized, the calculation cost is reduced, the calculation precision is improved, and the method has high time-space continuity and practicability; the method is used for establishing the high-resolution motor vehicle dynamic emission list, the actual situation of road traffic emission can be reflected in time, and the space-time resolution of the emission list is improved.

    本发明提供了一种用于高分辨率机动车动态排放清单的路段的小时交通量测算方法,用以解决现有技术缺乏面向高时空分辨率机动车动态排放清单的路段的小时交通量测算的问题。所述小时交通量测算方法,基于FCD速度数据及交通流状态分类,依次构建FCD速度与交通量时空匹配数据、交通流模式数据库和基本图模型数据库构成测算模型数据库,再根据当前路段限制条件从测算模型数据库中调用相应测算模型,动态测算路段的小时交通量。本发明实现了路网中无监测交通量路段的小时交通量动态测算,降低了测算成本,提高了测算精度,具有高时空连续性和实用性;用于建立高分辨率机动车动态排放清单,能及时反映道路交通排放的实际情况,提高了排放清单的时空分辨率。
