| 摘 要： | 机动车行驶里程是计算机动车尾气排放量的一个重要参数.对全国数百个地级及以上城市不同车龄的机动车(包括轻型客车、公交车、出租车和摩托车)行驶里程进行了调查.结果表明:除公交车外,其他机动车的累积行驶里程均随车龄而呈现对数递减性,即车龄越长机动车的累积行驶里程增加越慢,年使用率越小;某类型机动车车队的年均行驶里程与调查基准年的各车龄机动车的保有量相关;提出了轻型客车年行驶里程和车龄的经验公式,并得到2007年轻型客车的年均行驶里程为2.691×104km.

| Abstract: | Vehicle mileage traveled is an important parameter in exhaust emission calculation.Sample vehicles of different ages and types,including light duty passager vehicles,buses,taxis and motorcycles were investigated in the cities of China to get the distribution of vehicle mileage.The results indicated that,for all vehicles except buses,the accumulated vehicle mileage traveled may be modeled by a logarithmic function of the age,meaning that the increase of vehicle mileage and usage decreased with age.The averag... |
