动态称重系统数据采集及分析

Data Collection and Analysis by Using Weigh-in-motion

采用山东省永久路面试验路的动态称重系统,详细介绍了动态称重系统的组成结构、动态称重系统的安装以及轴型的分类,并对所采集的轴载数据的处理方法进行了介绍和比较。在此基础上,分析了道路通行车辆的实际轴载谱、不同类型通行车辆的轴载变化、试验路段交通量的日、周、月变化以及车辆的速度变化,通行车辆的车道分布等,结果表明,实时采集车辆通行数据的动态称重系统所采集的数据库数据可以有效地解决原来轴载调查使用方法存在的与实际轴载不符的问题。

The weigh-in-motion（WIM） system installed on the Shandong perpetual pavement test road was adopted.The composition structure,installation of WIM system and the axle type classification were described in detail,and the treatment methods of collected axle-load data were introduced and compared. On this basis,the actual axle load spectrum,the axle loads of different vehicle types,daily/weekly/monthly traffic volume,velocity and lane distribution of vehicles were analyzed.The result shows that the collected data in database of WIM system that collecting real-time data dynamic movement data of vehicles can be used to effectively resolve the problem that the outcomes of the axle load survey methods are inconsistent with the actual axle loads.
