摘要
基于重庆市高速公路发展有限公司提供的一周WIM数据,对不同类型的车型(轴型)出现概率统计出7种常见车型(轴型),并且对总轴重样本与分轴重样本进行了荷载频率统计、曲线拟合、函数拟合以及分布假设与检验,得出重庆市现有高速公路交通流量的总轴重(车重)基本满足要求的结论。
Based on one week＇s WIM data provided by Chongqing city expressway development Co. Ltd, the author calculates out 7 kinds of common vehicle type （axle type） aiming at different kinds of vehicle types＇ appearance probability, and gets loading frequency statistics, curve fitting, function fitting and distribution hypothesis testing to general and partial axle load, finally draws a conclusion that the general axle load （vehicle load） of existing expressway traffic flow in Chongqing city meets the basic requirement.
