高速公路交通流数据检测技术

结合应用实践，介绍了现代交通流检测技术——视频检测技术、磁映像技术、橡胶气压管传感器技术和远程微波传感器技术的工作原理及在高速公路交通流检测中的应用，对每种检测设备的适用条件、安装要求进行了详细论述。并以MetroCount 5600车辆分型统计系统的Traffic Executive交通量管理软件为例，对高速公路的交通流参数关系进行分析。实践证明，以上4种检测技术能为高速公路交通流特性研究提供所有交通流参数，为高速公路交通流特性研究提供有力的数据支持。

Data Detection Techniques for Traffic Flow of Expressways

According to application experiences, the work principles and applications of detecting traffic flow of modern detection technique, such as video detection technique, magnetism reflection technique, rubber gas press pipe sensor technique and long-distance microwave sensor technique are introduced, and adaption conditions, install request of each equipment discussed. Last,the relations among three traffic parameters are analyzed by Traffic Executive Software of MetroCount 5600 as an example. Practice proves that four detection techniques can provide all traffic flow parameters for studying expressways and provide data support for studying traffic flow characteristic powerfully.
