Abstract: With a light bus as the target vehicle in this paper, the typical load data in different regions in China are collected and analyzed. Through the statistical analysis of load data, the target loads in each region are established by the combination of rainfall extrapolation and mileage extrapolation. Then the weights for target loads in all regions are given by using analytical hierarchy process, grey correlation analysis and structure entropy weight method respectively, with their results of weights used to establish corresponding user target loads. The target loads established with three methods are comparatively analyzed and the results show that the target loads established by structure entropy weight method are most reasonable

Key words: light bus, user target load, load extrapolation
