| 摘 要： | 以运行车辆为质点,提出采用汽车道路作用空间的物理分析方法来研究车辆当量系数换算问题。建立了车辆道路作用空间模型,通过大量试验数据分析和应用随机场论的分析方法,研究确定了汽车在运行过程中所表现出的横向、纵向道路作用空间特性以及与道路、交通和车型等相关因素的定量数值,并由此推算出了基本车辆当量换算系数,和基于不同公路服务水平条件下的车辆当量换算系数。

| Abstract: | Taking moving vehicle as a particle,method of using the physical analysis base on road action space for studing vehicle equivalent coefficient is suggested.The conception,mechanism and characteristic of the vehicle road action space is discussed,and its mathematics model is set up.By analysing a great number of the experiment data and appling method of the stochastic field theory,crosswise and lengthwise road action space properties running on the road,and the quantitative values related to roads,stream and vehicle types are analysed and determined.Thus the vehicle equivalent coefficients both fundamental and under conditions of different level of service are calculated. |
