成都及其周边地区轻型载客汽车行驶里程调查与分析

研究目的是通过实地调查和统计分析及检验确定成都及其周边地区轻型载客汽车的活动水平(用行驶里程表征)及规律,并比较不同地区间的差异。统计表明,成都及周边城市轻型载客汽车的年均行驶里程为1.5~2.0万km/年。其中绵阳和其他城市间的差异比较显著,而其他城市间的差异在绝对值上较小。成都及其周边地区轻型载客汽车年均行驶里程随车龄呈递减趋势,以成都市最为明显,而周边其他地区稍差。结果表明,为提高机动车尾气排放清单的准确度,对城市差异较大的不同地区的轻型载客汽车的行驶里程进行分别调查是必要的。

The Investigation and Analysis in Mileages for Light-Duty Passenger Cars in Chengdu and Surrounding Cities

This paper aimed to investigate, do statistic analysis, test and confirm the vehicle activity level （ traveled mileage） and discipline of light-duty passenger cars in Chengdu and surrounding cities, and compare the differences between different regions. The results showed that the annual vehicle mileage traveled of light-duty passenger cars of Chengdu and its surrounding cities ranged from 15 N 20 thousands kin, with a significant difference between the Mianyang and other cities, and the differences between other cities was smaller in the absolute value. The annual vehicle mileage travel decreased by ages in Chengdu and surrounding cities, with Chengdu the most obvious and other regions not. This paper indicated that to enhance the accuracy of motor vehicle exhaust emission inventory, the respective investigation on the traveled mileage of light-duty passenger cars in the cities with big difference in different regions is necessary.
