The invention provides a high-emission road section identification method, which comprises the following steps: acquiring real-time road network data and vehicle data, estimating the traffic flow of each road section in a road network according to the road network data and the vehicle data, calculating the total emission of the road type to which each road section belongs based on the traffic flow of each type of vehicles on each road section and the length of the corresponding road section, and accumulating the total emissions of all the road types to obtain a whole road network emission list, and identifying high-emission road sections of which the emissions are higher than a preset value in the whole road network emission list. The invention further provides a device corresponding to the method, electronic equipment and a storage medium. The method is based on vehicle real-time emission monitoring data, the calculation accuracy of a road network emission list is high, vehicle emission is subdivided into hour road sections, the vehicle emission time and spatial resolution are high, the time change rule of high-emission road sections can be dynamically obtained, and the correct recognition rate of suspected high-emission road sections is high.
本公开提供了一种高排路段识别方法,包括:获取实时路网数据及车辆数据,根据路网数据和车辆数据,估算路网中各路段的车流量,基于各路段上各类型车辆的车流量和对应的路段的长度,计算各路段所属道路类型的总排放量,将所有道路类型的总排放量进行累加,获得全路网排放清单,识别全网排放清单中排放量高于预设值的高排路段。本公开还提供了与方法对应的装置、电子设备和存储介质。该方法基于车辆实时排放监测数据,路网排放清单计算精准度高,车辆排放细分至小时路段,车辆排放时间及空间分辨率高,可动态获得高排路段的时间变化规律,疑似高排路段正确识别率高。
