摘要
以某高速公路桥梁健康监测系统为例,选取2019年4月25日—2019年5月8日期间基于多条压电薄膜传感器的高精度动态称重系统车辆荷载监测数据,对车流量、车速、车重、轴重等进行分析,全面了解该高速公路桥梁周边地区机动车出行特性和交通构成情况,把握现有公路的交通流量、流向,为后期高速公路改扩建项目的远景交通量预测提供数据支撑。
Taking a highway bridge health monitoring system as an example,this paper chooses the vehicle load monitoring data of high precision dynamic weighing system based on piezoelectric thin film sensors from April 25,2019 to May 8,2019 to analyze the traffic flow,speed,load and axle load,and comprehensively understand the motorization around the highway bridge.Traffic characteristics and traffic composition,grasp the traffic flow and direction of existing highways,and provide data support for the future traffic volume prediction of highway reconstruction and expansion projects.
