干线交通流量采集传感器布局研究

交通流量采集传感器在交通控制中起着极其重要的作用,它是交通控制系统中控制参数采集的主要工具,它为干线协调控制提供基础数据,是决定交通信号控制精度的主要部件。本文通过对干线交通的研究,研究了干线交通中交通流量采集传感器布局。首先,讨论了干线中测速对传感器在车道上布局的影响。其次,考虑传感器的采集可靠性,给出了干线不同车道上车流量之间的相似度估算公式,讨论车道上传感器利用率的情况。最后给出了干线交通流量采集传感器的优化布局的整体思路。

Study on the Layout of the Traffic Acquisition Sensor

Traffic acquisition sensor which is one of the main tools for data acquisition in traffic control system plays an important role in traffic control.It provides the basic data for the coordinated control of main roads,also determines the control accuracy of the traffic signal and the acquisition of control parameters in the traffic signal control system.Through the study of the main roads,the layout of the traffic acquisition sensor in the main road traffic is discussed.Firstly,the impact of cars' speed meas...
