摘　　要：基于GPS/GIS数据的短行程工况构建方法,根据统计结果计算得到城市区域、道路等级和运行时间段的加权因子,并阐述了加权因子的运用方法.针对城市道路等级的特点,将工况分为支路、干道、主干道和快速路4个部分,根据短行程的方法分别构建.将各部分构建的工况组合得到完整的城市工况.计算构建工况的特征参数,并与整个城市短行程数据库的特征参数比较,发现平均相对误差为2.12%,能代表道路的实际行驶工况.A modified short trip cycle development method is proposed,based on GPS/GIS data,different weighting factors to area,road level and running period are given according to the statistic result,and the ways to apply these weighting factors are defined.In accordance with different road levels in urban area,the driving cycle consists of four phases which respectively represent the fast road,main artery,artery and trail.All phases are developed via shot trip method and the whole driving cycle is achieved by combining the four phases.Characteristic parameters of the developed cycle are calculated and compared with that of the urban short trip database,with the finding that the average relative error is 2.12%,which proved the representatives of the cycle developed.
