摘　　要：回顾了多种当量车PCE的计算方法 ,不同的计算方法结果大不相同。文章以车辆相互影响的根本原因出发 ,用反映汽车动力学特征的动力因数作为评价PCE的量标 ,该计算方法更能反应汽车的行驶速度随道路条件变化的情况 ,车辆的速度变化伴随着动力性的变化。用动力因数来计算PCE的新方法 ,能更准确反映实际车流中车型间的差异 ,更加适合中国的道路和交通条件。但其计算过程比较复杂 。There are many methods to calculate passenger?car equivalents(PCE), but the results from different methods vary largely From the fundamental reason why vehicles interact each other, this paper presents a new method using power factor as measurement to evaluate PCEs Power factor in this method can not only reflect the process of travel speed varying with road condition and vehicle dynamic characteristic better, but also describe the vehicle type differences existing in practical traffic stream exactly More accurate and adaptive China road and traffic conditions results can be obtained by using this new method, but it is difficult to compute PCE value that needs more detailed power parameters of vehicle types
