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.
